River Otter

River Otters, Lontra canadensis, are members of the weasel family. They can be found in a variety of freshwater bodies including rivers, creeks, swamps, marshes, ponds, and lakes throughout Florida with the exception of The Keys. Otters love riparian areas where they can make their burrows under tree roots on a bank and slide into the water for a tasty dinner of fish, crustaceans, reptiles, and amphibians. They also dine on insects, birds, and small mammals.

River Otters weigh 15-30 pounds and live to 12 years old, They and are skilled swimmers. When they aren’t playing in the water or mud, you will find them marking their territory with urine, feces, scent glands, and scratch marks on trees. Females give birth to one to six pups in a den dug into the bank of a body of water or a hollow log. When they are two months old, the mother otter pushes her pups into the water where they quickly learn to swim.

Fun Fact: River Otters can hold their breath for 8 minutes.

Hidden Waters Preserve

Once known as the Eichelberger Sink, this 90-acre preserve located near Eustis is managed by Lake County Water Authority. Hidden Waters Preserve was established in 1996 to protect the water seepage and Lake Alfred where water slowly seeps into the aquifer.

Hidden Waters Preserve offers 6 trails ranging from 2 miles to 15 miles. Hike the meandering paths through sandhill restoration areas. Notice the newly planted Long-leaf pines and the gopher tortoises who make their burrows there. Water flowing from a seepage slope offers the opportunity to discover various plants and ferns.

The elevational difference between the top of the sink and the bottom is 110 feet. Explore the depression marsh and lake at the bottom of the sink where you will find a variety of plants and wading birds. Bird watchers will be happy to discover some of the more than 35 birds on this designated FWC Statewide Birding Trail.

Eastern Coral Snake

Eastern Coral snakes, Micrurus fulvius, have a bright, glossy, distinct pattern. Their heads are black and their tails are yellow and black. Red and black rings separated by thin yellow rings make up the rest of their body.

An adult Coral snake will grow to 1 1/2 to 2 1/2 feet long. Prey consists of frogs, lizards, and other snakes. Coral snakes are the only venomous snakes in Florida that are part of the cobra (Elapidae) family, therefore, they lay eggs.

From scrubs to swamps, Eastern Coral snakes can be found in numerous habitats throughout Florida. Because they spend most of their time hiding under logs or underground, an occasional Coral snake sighting can be a wonderful discovery.

A bite from this venomous snake is extremely rare, however, their bites are dangerous to pets and people. Bites occur when the Coral snake is threatened. When you discover a coral snake, simply give it space so we can peacefully coexist.

Little Big Econ State Forest

Little Big Econ State Forest

Located in Geneva in eastern Seminole County, the Little Big Econ State Forest gets its name from both the Econlockhatchee River and the Little Econlockhatchee River. Econlockhatchee means “earth-mound stream” in the Muskogee language and was named by the native Americans for the numerous mounds found along the river.

Before being established on March 24, 1994, by the Florida Legislature, the property was used for cattle ranching, crops, as a turpentine distillery, and for a portion of the Florida East Coast Railway. Today the 10,336 acres in the Little Big Econ State Forest is an outdoor enthusiast’s paradise.

Seventeen miles of the Econlockhatchee River, which has been designating an Outstanding Florida Waterway, makes its way through the forest before flowing into the St. Johns River on the eastern boundary. The Little Big Econ State Forest boasts a variety of habitats including wet prairie, pine flatwoods, sandhill, scrub pine, flatwoods, scrub, sandhill, and oak-palm hammocks.

Over 160 bird species have been spotted in the forest including Bachman’s sparrows, crested caracara, wood storks, swallow-tailed kites, and sandhill cranes. Look for fox squirrels, gopher frogs, gopher tortoises, turkeys, deer, and alligators.

The Little Big Econ State Forest has been named one of the country’s most family-friendly hikes by the American Hiking Society. Saunter along the 5.2-mile loop Kolokee Trail, discover wildlife along the 8 miles of Florida National Scenic Trail, or explore any of the 15 miles of trails located in the forest.

Paddle all or a portion of the 20 mile-long Econlockhatchee River Paddling Trail. There are 12.1 miles of bicycle trails and 9.3 miles of equestrian trails complete with a water trough.

Primitive camping sites are available and some have a picnic table and fire ring.

Reserve the picnic pavilion for your special events.
Enjoy your lunch at a picnic table. Your leashed pets are welcome.

Whether for a day or a week, there is plenty to explore and discover at the Little Big Econ State Forest.

Snail Kite

Snail Kites can be found flying low over open freshwater and marshes in Central and Southern Florida before dropping down to snatch an apple snail with their talons. They will fly to a perch and use their unique-shaped bills to pry the snails from their shells. Look for Snail Kites roosting in flocks just before hunting and during nesting season.

Listed as endangered in Florida since 1967, Snail Kites (Rostrhamus sociabilis) depend on good quality water to survive. Urban development, sewage seepage, nutrient and pesticide run-off, and invasive plants have degraded much of Florida’s freshwater. Nearly 1/2 of the Everglades have been drained. Since a Snail Kite’s diet consists almost exclusively of apple snails that only live in freshwater areas, it is imperative that we protect the remaining wetlands.

Green Anole

Green Anoles (Anolis carolinensis) are native to Florida. They are found in natural and suburban areas throughout our entire state.

Adult Green Anoles grow to 5-8 inches long. Males have a solid pink throat fan known as a dewlap. Anoles can quickly change from bright green to a dull brown color to blend into their surroundings. Their favorite foods are roaches, beetles, flies, spiders, and other small invertebrates, which makes them beneficial to your garden.

You may find these lizards hiding in shingles, under tree bark, or in rotting logs in cool weather. In warmer weather, look for them basking in plants, on fence tops, or on rooftops. Females lay single, round eggs in rotting wood or moist soil throughout warmer months. The tiny lizards emerge from their eggs, looking like miniature adults.

The biggest threat to Green Anoles is the introduced Cuban brown anole. Because they are great climbers, Green Anoles move vertically up in their habitat, which allows them to decrease competition by claiming the higher habitat among the trees as their own.

House Sparrow

House sparrows were introduced at various stages throughout New York (Barrows 1889), Maine, Massachusetts, and Nova Scotia. Some of these releases were a sentimental connection to the homeland of many European immigrants. Others were to help control cankerworms or linden moths(Marshall 2014). In some cases, the release of house sparrows failed and the birds died without breeding. One of the more successful attempts was in Nova Scotia. This population spread and the presence of other populations in the U.S. Northeastern states may have helped them thrive.

Today, house sparrows have spread throughout all of the United States, most of Mexico, and the southern parts of Canada. They have even made their way to South America. In most regions, they are considered an invasive species due to their aggressive and territorial tenancies. They will even go to such extremes as to damage the nests of other birds. They out-compete many native birds for food and reproduce at a rapid rate making them difficult to control. Oddly enough, many places in Europe are seeing declines in house sparrow populations. The United Kingdom has a 71% reduction since the mid-1990s. This decline has been linked to avian malaria and areas of increased nitrogen dioxide. Italy experienced a 49% decline in house sparrow populations from reductions in nesting sites, reduced food availability, and possible disease. Paris reported a 12.4% reduction by year primarily due to city gentrification. Yet, these birds continue to thrive in North America.

One way you can help is by providing a nesting box for house sparrows. If eggs are laid you can simply poke them with a pin to prevent the eggs from further developing. Removing the eggs entirely can cause the female to produce more eggs at a faster rate. Removing an entire nest could force sparrows into more wild landscapes and could pose a greater threat to native birds. While we might never be able to fully eradicate house sparrows from Florida, it never hurts to try and reduce the growing population.

House Sparrows are sexually dimorphic with the male having a classic black mask across his eyes. The photos below show a male (Left) and female (Right).

Viera Wetlands

– Viera Wetlands –

One mile of shoreline, wildflowers, and birds draw over 200,000 people each year to the Ritch Grissom Memorial Wetlands which is commonly known as Viera Wetlands. Named in honor of a long-time Brevard County employee and awarded a grant by the Florida Wildflower Foundation, the wetlands are a popular destination for ecotourists, birders, photographers, and wildflower enthusiasts.

There are 200 acres to explore at Viera Wetlands. Walk or bike around the berms. Enjoy the scenery from your car as you leisurely drive no more than 10 mph along the one way, unpaved road. (The road is occasionally closed to vehicles when too wet.) Revel in the beauty of wildflowers along the banks of the lakes and ponds. Notice the different plants in dry areas as well as those in wet areas. The plants work together to stabilize the soils without the need for fertilizers and irrigation. What pollinators will you discover?

Birds abound at Viera Wetlands which is included in the Great Florida Birding Trail. Get a better view of the wetlands from the observation tower. Keep your eyes open otters, marsh rabbits, and raccoons who make their homes there along with an abundance of amphibians and reptiles. Look for beautiful butterflies and striking Painting Buntings.

Bobcat

The Florida Bobcat (Felidae Rufus Floridanusare) is one of two predatory cats native to the Florida region. Despite being the only two native wild cats to Florida, Bobcats and Florida Panthers diverged from two different lineages. Bobcats are a species of lynx. The lynx line diverged from a common ancestor 7.2 mya. The Puma lineage which the panther diverged from did not appear until 6.7 mya. Twice the size of domestic cats and weighing 12-28 pounds, Bobcats are often mistaken for the larger endangered Florida Panther.

Florida Bobcats are immediately identifiable by their short tails or bobs.  Fringes of fur outline the sides of their heads. Their tails have white on the underside and black markings on the top side. They have spots of white fur on all parts of their body which can range in color from reddish-brown to grey. 

Female bobcats require approximately 5 square miles of range while males require 15 to 30 square miles.  The mating season occurs from August to March with the peak time occurring in February and March.   The den can consist of a hollow tree, cave, rock outcropping, or other open shelters. Dense shrub thickets and saw palmetto provide cover for private dens. One to four spotted or mottled kittens are born in the early spring.  Coyotes effectively regulate the Bobcat population when they prey on cubs. Florida Bobcats live up to 14 years.

Bobcats can swim and climb trees with ease, two factors that prevent them from falling prey to natural enemies besides human hunters. Bobcats usually hunt at night but can often be spotted during the day. Dinner consists of birds, carrion, rats, rabbits, raccoons, opossums, and squirrels.  Towhees, thrashers, catbirds, and other ground-dwelling birds provide winter treats.  Florida Bobcats play an important role in the ecosystems they inhabit by helping to control their prey animals’ populations.

This native species is abundant in Florida and can be found in forests, swamps, and hammocks. Though bobcats are stealthy, elusive, and show no interest in people, they are often seen in suburban yards and even city streets from time to time.

Bobcats typically do not approach humans but will do so if fed and taught to associate people with food. When living with Bobcats, we must do our part—secure chickens and other small pets in an enclosed pen. Domestic cats and dogs should not be left alone in your yard or on a screened porch. Always walk your dog on a leash. With just a little common sense, we can truly coexist with these magnificent cats.

Fiddler Crabs

Fiddler Crabs (Genus uca) live in the tidal sands of mangroves and salt marshes. They are experts at sensing the ebb and flow of the tide because their survival depends on it. Although they have gills, Fiddler crabs can drown if there is too much water. They retreat to their 12″ burrows in the sand at high tide and seal the burrow with mud or sand.

During low tide, Fiddler Crabs colonies get down to business doing their part for the ecosystem when they come out in the hundreds to work and eat. To build and maintain their burrows, they use their small claws to move sand to their mouths, where they strain and extract nutrients. Clean sand pellets are spat out. Although their diet consists of algae and decomposed matter, Fiddler Crabs are tasty meals for shorebirds, fish, and land mammals such as raccoons and foxes.

Female crabs incubate eggs for 2 weeks. During high tide, the female will release the larvae who will float away. In a few weeks, the surviving young crabs will drift back to shore and join a Fiddler Crab colony.

Male Fiddler Crabs have one oversized claw that looks like a fiddle. While it is sometimes used to defend against other male crabs, the large claw is primarily used in courting rituals. To woo his desired female, the male Fiddler crab will dance while waving his giant claw until the lady agrees to join him in his burrow.

Short-tailed Kingsnake

Short-tailed kingsnakes (lampropeltis extenuata) are as thin as a pencil and grow to an average length of 14 to 20 inches long. Their scales are smooth and gray with a spotted pattern. They have dark spots down the middle of their backs as well as on their sides. The lighter color between the spots has an orange center.

The Short-Tailed Kingsnake has a small oval-shaped head and round eyes. As the name implies, their tails are shorter than the tails of other snakes. This snake is nonvenomous and is not a threat to people. The Kingsnake consumes other snakes and lizards. They spend their lives below ground and are rarely seen. This snake is so rare that it is assumed eggs are laid below ground where it burrows. Reproduction has not been studied; therefore, nothing is known about the number of eggs in the Short-tailed kingsnake’s clutch. They can be found in north-central Florida habitats, such as pine or coastal live oak hammocks and sand pine scrub.

The Short-tailed Kingsnake is endemic to Florida. This snake is listed as threatened and protected by Florida state law. Their range is limited, and conversion of habitat to citrus, mining, and development pose ongoing threats.

Gray Fox

The Gray Fox is a member of the dog family, Canidae. This fox is common in Florida and can be found statewide except for the Keys. Their preferred habitat is dense cover in thickets, forests, or swamps.

The Gray Fox is also known as the Tree Fox as they are the only fox species that climb trees to evade predators and hunt prey. Gray foxes climb in a scrambling motion, grasping the tree trunk with their forepaws and forcing themselves higher with long claws on their hind feet.

Gray Fox’s diet consists of small mammals, insects, fruits, acorns, birds, amphibians, reptiles, carrion, and eggs. Due to their ability to climb, squirrels are an important source of food. Rabbits, mice, and rats are their preferred food.

The upper side of their bodies is salt and pepper gray. The nose and the sides of its muzzle are black. A black line extends from the corner of their eyes to their neck. The sides of their neck, backs, legs, the underside of their tails, and the base of their ears are all bright reddish-orange. A black stripe runs along the bushy tail, which measures 11 to 16 Inches. Gray Foxes grow to a height of 15 inches and 21 to 30 inches in body length. They weigh 7 to 13 pounds.

Gray Fox dens are located in hollow logs, ground burrows, beneath boulders, and even under buildings in areas where the foxes have become acclimated to people. The breeding season occurs from late January to March. Females give birth to 3-7 dark-brown, blind pups after 50 to 55 days. The male stays with his mate to care for the young, which are weaned at about 2 months. By 3 months, they leave the den with their parents, who teach them to hunt. They stay with their parents until late summer or fall.

Cane Toad

The Cane Toad (Rhinella marina) is an invasive species. Native to Central and South America, it was released in Florida in the 1930s-1940s to control sugar cane pests.

Cane toads grow to between 4 to 6 inches. Their coloration ranges between tan, brown, reddish-brown to gray. The skin is warty and the back is marked with dark spots. They do not have ridges or crests like the native southern frog. They do, however, have large triangle-shaped parotoid glands, which appear prominently on the shoulders. Breeding takes place from March to September along vegetated, freshwater areas and they lay their eggs in a long, string line, like native toads.

Cane toads are predominantly found in Central and South Florida. They can be found in urban areas as well as agricultural areas, flood plains, and mangrove swamps.
Cane Toads prey on anything that fits in their mouths. Unfortunately, their prey often consists of native frogs, lizards, snakes, and small mammals.

Toxin from a cane toad can irritate a human’s skin and eyes. If a pet bites or swallows a cane toad, they will become sick and the toxin may be fatal. FWC states, “A cane toad’s toxin can kill your pet in as little as 15 minutes without proper treatment. If your pet bites or licks a cane toad, it will likely start acting strangely with frantic or disoriented behavior. It may also have brick-red gums, seizures, and foam at the mouth.”

FWC recommends “If you see these symptoms and believe your pet licked or bit a toad, immediately wash toxins forward out of the mouth using a hose for 10 minutes, being careful not to direct water down the throat. Wipe the gums and tongue with a dish towel to help remove the toad’s milky, white toxins that will stick to your pet’s mouth. Once you have done this, get your pet to a veterinarian as quickly as possible.”

Keep your cats indoors and your dogs close by when you take him or her outside.

FWC offers these tips to make your yard less attractive to cane toads:

  • Cut your grass regularly and keep it short.
  • Fill in any holes around structures.
  • Trim the underside of shrubs and keep branches off the ground.
  • Clear away brush piles and remove clutter.
  • Feed pets indoors when possible and bring outdoor pet food and water bowls indoors at night.
  • Clean up any food scraps from pet bowls or outside tables and grills.

Sweat Bee

Sweat Bees (Halictidae) are also known as Halictid Bees. They vary greatly in appearance. The majority are dull to metallic black, with the remaining species being metallic green, blue or purple. These bees do not sweat; they are attracted to human sweat. These non-aggressive Bees use the salt from human sweat for their nutritional needs. Sweat bees are important pollinators for many wildflowers and crops, including stone fruits, pears, and field crops. Halictids typically nest in bare soil located in a sunny location. Most halictids nest underground, but some will nest in rotting wood. The bees help speed the decay and decomposition of deadfall trees. In the spring or summer, the female mates. She then begins digging a nest and providing cells with pollen and nectar. Cells containing an egg or larva are lined with a waxy substance, which is extruded from a gland on the underside of the bee’s abdomen. In each cell, a single egg is laid. When the larva hatches, it eats the pollen provided. Once that is eaten, it must become self-sufficient and find its own food source. Males will usually resemble the female of the same species, but the male sweat bee does not have an area of long, dense hairs on its hind legs used for carrying pollen. They may have a yellow spot below the antennae on their face. As these bees feed on nectar and pollen, they are pollinating in the process. These technicolor bees do add a flash of brilliance to a spring garden.

Turkey Buzzard

Let’s talk about the Turkey Buzzard (Cathartes aura), nature’s sanitation engineer, and when joined by friends, the ultimate clean-up crew.

Turkey Buzzards are also known as Turkey Vultures. They have black or dark brown feathers, and their featherless heads and necks have pink skin. They are between 25 to 32 inches in length and weigh up to 6 pounds. They have a wingspan of 54 inches.

Turkey vultures use thermal currents to float on the warm air currents without flapping their wings, conserving energy. They will travel 30 to 50 miles on these currents in search of food. Their bills and feet are not designed to catch prey, and they prefer to eat fresh roadkill and other carrion.

The Turkey Buzzard has a keener sense of smell than other birds. They can smell the chemical breakdown of carrion from a mile away and will float and follow the aroma until they find it. Their bald, featherless heads make it safer for them to stick their heads deep into the carrion, and nothing will stick to the smooth skin.

As carrion eaters, many consider Turkey Buzzards spooky and harbingers of death. If you see one of these vultures circling above you, it doesn’t mean you are about to die. These Buzzards have a unique and ecological role because they prevent the spread of disease from rotting carrion by eating it.

Since they have weak legs and cannot carry food back to their young, they will gorge on a carcass and regurgitate to feed the young. They will also urinate on their legs and feet to cool off. Their urine kills any parasites and bacteria from walking and standing on the carcasses. When threatened, they will vomit to lighten their body weight to escape as a defense mechanism against predators.

Turkey vultures are highly social. They will fly in a small group and breed annually with the same mate. The vulture can be found in pastures, landfills, or anywhere they can find carrion. Eggs are laid on the ground in dense thickets, scrub areas, hollow logs, caves, or old buildings. The Turkey Buzzard lays between one to four clutches from March to July. Their eggs hatch in 35 to 40 days, and the nesting period is 55 to 90 days.

Vultures are a protected species, which means that interfering with them physically has legal repercussions.

Lightning Bug

Let’s be a kid again with the Firefly/Lightning Bug!

Remember those nights of wandering outside in the spring and summer and being surrounded by amazing little flying strobe lights. They would come out at dusk and stay only for a few hours. We captured them in glass jars and looked in amazement as we tried to figure out how their lights worked.

Fireflies are a good indicator species for the health of an environment. Unfortunately, these little miracles of life are on the decline throughout the world because of overdevelopment, pesticide use, and yes, light pollution.

The best thing you can do to support fireflies is to stop using lawn chemicals and broad-spectrum pesticides. Firefly larvae eat other undesirable insects. They are nature’s natural pest control.
If you miss seeing these little buggers, you’ll be happy to know Central Florida’s firefly season is at the end of March and early April. In fact, Blue Springs State Park stays open a little past their usual closing time and has guided tours at this time so you can enjoy nature’s light show.

Dolphin

Dolphin is a common name of aquatic mammals within the order Cetacea. Dolphins can be very large, reaching weights of up to 1400 pounds and lengths of 12.5 feet. They can live between 40 to 50 years and reach sexual maturity between 5 and 14 years.

Like all mammals, dolphins reproduce through internal fertilization, and females give birth to live young. The gestation period is between 9 to 17 months, depending on the dolphin. Juveniles are able to swim from the moment they are born, but for two years, they are dependent on their mothers for nursing.

Dolphins are thought to be some of the smartest animals on the planet. They are also extremely curious, and their intelligence is both a result and a driver of their complex social structures.

They generally live in pods between five to several hundred depending on the type of dolphin. Their preferred prey includes small, schooling fishes and squids. There are over 40 species named as dolphins, from freshwater to saltwater. Most species live in tropical and temperate oceans throughout the world. Five species live in the world’s rivers. They use echolocation to find prey and will hunt together by surrounding a school of fish, trapping them, and taking turns swimming through the school to catch the fish.

They have a vocabulary of danger sounds, food sounds, and seeking sounds. Sometimes they put these sounds together in a reasonably complex fashion. They are known to vocalize one to the other. Studies also indicate that there are differences among dolphins’ species regarding their skull size and form, variations that may lead to future changes.

As with most species today, the dolphins’ most dangerous threat is man. Sometimes, humans kill dolphins not because they are a food source but because they prey on the same fish species as humans do. Therefore, many fishermen have killed dolphins only because they are a competition for the fish. In some countries, people eat dolphins. In Japan, some species’ meat is seen as a delicacy and can cost up to $25 USD a pound. The presence of humans on Earth does not give dolphins many possibilities to survive. If they are caught in the fishing nets, they are unable to breathe and drown. There is a loss of habitat due to pollution. Millions of gallons of polluted water, toxic substances such as pesticides, heavy metals, plastic trash, and hundreds of other hazardous materials are released into the ocean and the rivers. Their habitat becomes contaminated and causes illness and death. There are many positive interactions between humans and dolphins. They have rarely attacked people. Instead, they have helped them often. The truth is that there is nothing to indicate that dolphins feel particular empathy for man since they have a highly developed social behavior. They behave the same way with other animals.

Fun Fact: While sleeping, the bottlenose dolphin shuts down only half of its brain, along with the opposite eye. The other half of the brain stays awake at a low level of alertness. The attentive side is used to watch for predators, obstacles, and other animals. It also signals when to rise to the surface for a breath of air. After about two hours, the animal will reverse this process, resting the brain’s active side and awaking the rested half. This pattern is often called cat-napping

Horse Conch

The state shell of Florida,  designated in 1969., is the Horse Conch (Triplofusus giganteu).  The word “conch” comes from a Greek word meaning “shell.” The Horse Conch is the largest snail found in American waters and can grow to a length of two feet.  It’s easily identified by the bright orange body. The shell is grayish-white to salmon in color and covered with a brown, scaly outer layer, that you will see peeling. The 10 whorls of the shell are knobbed. Young shells are orange. The animal inside the shell is orange to brick red in color. The shell protects their soft bodies from predators. Horse Conchs use a foot that extends from their shell to drag the shell along.

Horse Conchs are commonly found in seagrass beds and reefs. This snail is carnivorous and will feed on clams and mussels as well as other snails. They consume algae and detritus (poop and parts of dead organic matter.) The female attaches capsule-like structures to rock or old shells. Each capsule contains several dozen eggs. Not all eggs are fertile. Non-fertile eggs are eaten by those who are maturing in the same capsule. When the young emerge they are an orange color and usually 3.5 inches in diameter.

Commercial harvesting requires a permit and there are limits. In some areas, it’s illegal to collect them. Lee County does not allow their harvest and Manatee county does not allow more than two per day. Keep in mind that while it may be tempting to collect large numbers of shells, other organisms rely on their shells for a safe living space after the conch dies. It’s best to admire Horse Conchs for a brief time and leave it for someone else to appreciate.

The Horse Conch’s predators are primarily humans who use them for their shells and food. Other predators are octopuses who use their suction cups to suck the conch out of its shell. Some starfish can slip one of their arms into the opening of the conch and then force their stomach out and ingest the conch right from its shell. 

This photograph shows how Horse Conchs make little Horse Conchs.

Green Sea Turtle

Marine habitats surrounding the Keys provide habitat for threatened and endangered species. The Florida population of Green Sea Turtle (Chelonia mydas) has been considered endangered since 1978. The declining population has been a victim of commercial harvesting for eggs and food and incidental bycatch in the shrimp fishery. Florida is an important sea turtle nesting area. The majority of nesting in Florida occurs between May 1st and October 31st. About 90% of all sea turtle nesting in the United States occurs on Florida’s beaches. To prevent nesting and hatchling turtles from wandering off track, your beachfront property should use sea turtle-friendly lighting. Never touch a sea turtle or pick up the hatchling; it interferes with the process of imprinting on their beach.

The Green Sea Turtle has a rounded, oval body with a distinctive smaller head. Its name is derived from the greenish fat in its upper and lower shell. Incubation lasts approximately sixty days. As the nursery due date, between 4 to 5 days, comes closer, a depression forms in the sand that indicates hatchling movements. Soon, the babies begin digging out en masse to start their journey to the water’s edge. The reflection of the moonlight on the water inspires their pathway to the sea. Turtles deposit approximately 100 golf-ball-sized eggs, gently cover the eggs with sand, and then spread sand over a wide area to obscure the chamber’s exact location. A single female may nest several times during a season and then not nest again for one or two years. A male Sea Turtle never leaves the ocean. The Turtles live between 12 to 50 years. Once in the water, the hatchlings swim directly out to sea, facing a struggle to survive to adulthood. They range in size between 3 to 5 feet and weigh anywhere between 240 to 420 pounds. They mainly eat seagrass and algae, the only sea turtle that is herbivorous as an adult. Their jaws are finely serrated, which aids in tearing vegetation. The estimate is there are between 85,000 to 90,000 nesting females. It may seem like many nesting females are laying eggs, but the Green Sea Turtle is facing a high risk of extinction in the wild in the near future.

Crocodile

Florida is famous for many things, one of them being the only environment on earth where American Alligators and American Crocodiles coexist. You may wonder what the difference is between the two. While they are related and do look very similar, crocodiles and alligators have some major differences. Crocodiles exist both in freshwater and saltwater, whereas alligators prefer freshwater environments.

The obvious difference is their appearances. Crocodiles have longer, pointier snouts. Alligators have shorter, more rounded snouts. When an alligator has its mouth shut, you won’t see any of its teeth. When a crocodile has its mouth shut, its back teeth stick up over the top lip. Because they are broader, alligator snouts are stronger than crocodile snouts, which allows them to crush hard-shelled prey such as turtles. Crocodiles are typically lighter in color, with tans and brown colors. Alligators are darker, showing more gray and black colors. Both members are excellent hunters. They have sharp, above-water vision, night vision, sensitive hearing, and vertical pupils that take in additional light. Both have small sensory pits along their jaws that allow them to detect pressure changes in the water and locate and capture prey. They both prefer to swallow large chunks or swallow their prey whole. Crocodiles have higher-functioning salt glands that allow them to excrete higher amounts of salt from water than alligators can. Alligator glands do not function as strongly, which makes them less tolerant of saltwater environments, so they prefer freshwater. Crocodiles can successfully migrate across multiple bodies of salt and fresh water.

American Alligators are regarded as more docile than crocodiles, only attacking if hungry or provoked. American Crocodiles are shy and reclusive. Crocodiles prefer to spend more time in the water. Alligators prefer to sunbathe on the banks or in the mud close to the water. Female alligators will continuously mate with the same male alligators for life. Crocodile babies come from multiple mates. Crocodiles live longer than alligators. The average lifespan of a crocodile is between 70-100 years, while an alligator’s average lifespan is usually between 30-50 years.
It would be best to avoid contact with both animals at all costs.

Red Velvet Ant

The Red Velvet Ant (Dasymutilla occidentalis) – the name is a bit misleading. These fuzzy little insects aren’t actually ants but rather wasps. The males have wings and can fly but are harmless. The females, however, can deliver a powerful and painful sting. Fortunately, they do not have wings and can easily be avoided. These differences in sexes are called sexual dimorphism.

These wasps create burrows in the ground that look like small holes. Chances are you have walked by the burrows without noticing.

Golden Silk Orb Weaver

The Golden Silk Orb-Weaver (Trichonephila clavipes) is dreaded by hikers and bikers in the forest. Their sticky, golden webs, which can measure 6 1/2 feet in diameter, are spun in insect flight paths in open woods and at the edge of dense forests. You may run into them in your yard, where they are spun between trees and dense shrubs. The large webs catch flies, bees, wasps, moths, butterflies, male orb-weavers, and more. The prey is devoured by the spider, who is waiting patiently on the web.

Golden Silk Orb-Weavers are also known as Banana Spiders because of their yellow coloring. Their color variation, complete with furry-looking tufts on their legs, helps them blend into the forest. They are also known as Giant Wood Spiders because the females’ bodies are more than 1 1/2 inches and, including legs, can measure up to 5 inches in diameter. Males are significantly smaller, with bodies at about 1/4 of an inch.

The small males come out to mate between July and September. The females produce at least two egg sacs per year but have been known to produce up to nine. Each sac contains a few hundred eggs. The female often eats the male after mating.

Climate change has mildly affected these spiders’ behavior. Still, they have adapted by creating reflective carapaces and turning the cylindrical parts of their bodies towards the sun to reduce the heated body surface. They also reduce heat by holding a drop of water in their chelicerae (mouth-part) and allowing it to evaporate. This has allowed them to adapt very well to their environment.

The next time these little ones give you a scare, take a few minutes to appreciate their hard work. Golden Silk Orb-Weavers play an important role in our ecosystems. Orange and pecan farmers appreciate their cooperation in keeping pests away from harvests. These fascinating spiders provide insect control in our wild spaces and our yards.

Robin

Robins

* Robins prefer cooler temperatures, which is why they fly north to escape the southern heat.
* Robins will start to migrate back north when they feel a 37-degree average daily isotherm ( ground temperature above 37*).
* Male robins will arrive at their northern destinations about 2 weeks earlier than the females. This gives them time to claim their territory. 
* Robins do not mate for life; however, the male will stay to help feed his chicks.
*Chicks leave the nest in August and live to be 5-6 years old.
* Robins begin to migrate south when the temperature causes the ground to become too hard to dig for earthworms, their main food source.
* Robins will resort to eating berries and insects until that food supply starts to dwindle.
* During migration, robins can fly up to 36 mph and cover 100-200 miles a day.
*Winter months are spent in Florida, southern Louisiana, southern Texas, southern Arizona, southern New Mexico, Southern California, and northern Mexico.
* Most robins migrate intermediate distances but some have migrated from Vancouver to as far south as Guatemala.

As the temperature warms in our neighboring states, robins will begin to make their way across Florida. Keep an eye on your birdbath. A flock of robins just might stop by for a quick dip and drink.

Florida Cracker Horse

The Florida Cracker Horse is a valuable and vital part of Florida’s heritage. While still rare, there are over 1,000 registered horses, which continues to grow yearly. The Florida Cracker Horse traces its ancestry to Spanish stock brought to Florida in the 1500s. They were given their name from the sound of the whips cracking as they worked cattle.

The Florida Cracker horse exhibits great endurance in an unfavorable environment. This horse exemplifies great patience and strength. The Cracker horse can work all day and night, traveling without additional care requirements. When the horses were left to roam freely, they evolved due to natural selection. They were tempered and molded by a challenging environment. In addition to playing an important role in the lives of Seminole Indians, they eventually helped Florida become a state of agriculture and ranching.

Through the efforts of several private families and the Florida government, the breed was saved from extinction, but there is still concern about its low numbers. The breed’s low numbers are considered to be at a critical point. The state has three small herds in Tallahassee, Withlacoochee State Forest, and Paynes Prairie State Preserve. The state maintains two lines for breeding and the line that roams the Paynes Prairie State Preserve for display purposes. By 1989, these three herds and around 100 other horses owned by private families were all that remained of the breed. The population is considered “critical,” meaning that there are between 100 and 300 active adult breeding mares in existence today.

Effective, July 1, 2008, the Florida House of Representatives declared the Florida Cracker Horse the official state horse.

Bald Eagle

The Bald Eagle, Haliaeetus leucocephalus, is more than the symbol of the United States. They are interesting enough to have an entire day dedicated to them. While Save the Eagles Day originated as a way to raise awareness about the then-endangered species, it now serves as a time to learn about the thriving animals. Here are five facts you may not know about eagles:

1. Females weigh more than their male counterparts. The males weigh between 7 and 10 pounds, and females can weigh up to 14 pounds.

2. Eagles can see as much as eight times further than humans, and their eyes are equipped with infection-fighting tears.

3. While the bald eagle population has steadily increased after a severe drop, most of the population’s fatalities remain human-related. Impacts with manmade structures, gunshots, and poisoning are the leading causes of death.

4. The Bald Eagle emits a surprisingly weak-sounding call. Usually, a series of high-pitched, whistling, or piping notes. The female may repeat a single, soft, high-pitched note that signals her readiness to copulate.

5. Eagles can dive up to 100 mph while hunting. When they’re flying casually, they go about 30 mph.

The bald eagle, the national bird of the United States, was once on the endangered species list, being on it from 1967 until 1995. It was then reclassified as being threatened. The Eagle was subsequently removed from that list in 2007 and is now listed in the least concern category.
The bald eagle is strongly associated with the United States, but eagles are on the coat of arms of Germany as well as on Egyptian and Albanian flags and coats of arms.
If you live near eagles, advocate protecting their habitat. The bald eagle is another example of a species brought to the brink of extinction that is now thriving.

American Alligator

American Alligators (Alligator mississippiensis) are found across Florida. These large, water-dwelling reptiles have a powerful bite and should be treated with extreme respect. They will generally seek to swim away if approached. However, if they think their young are in danger or if they feel threatened, they will strike out at the perceived danger. Alligators have round snouts, range between 9.5 to 15 feet, weigh as much as 1000 lbs. and have a maximum speed of 20 mph in the water. The alligator is a rare success story of an endangered species not only saved from extinction but that is now thriving. State and federal protections, habitat preservation efforts, and reduced demand for alligator products have improved the species’ wild population to more than one million today. They live nearly exclusively in freshwater rivers, lakes, swamps, and marshes. The hatchlings are usually 6 to 8 inches long with yellow and black stripes. Juveniles fall prey to dozens of predators, including birds, raccoons, bobcats, and other alligators, so they will stay with their mothers for about two years. They are opportunists and will eat just about anything, carrion, pets, and, in rare instances, humans. They feed mainly on fish, turtles, snakes, and small mammals. Adult alligators are apex predators critical to the biodiversity of their habitat.

Alligators get a bad reputation, but as long as we respect them from a distance, we have no reason to fear them. Alligators have ears directly behind their eyes. Do you see that part that looks like this alligator’s eyes are smiling? That’s its ear. The structure of the ear is designed to pinpoint sound rather than hear a vast amount of sound.

Female alligators lay between 32-50 eggs. If these eggs are hatched in the wild and not a hatchery, there is a chance that only a few eggs will survive. Predators such as birds, snakes, raccoons, otters, bobcats, bass, and other alligators can eat their eggs. According to FWC, an average of 25 eggs will hatch, but only about 10 alligators will survive their first year. These eggs and small gators become food so that other species can survive. In turn, large alligators may eat these same animals to ensure their survival. It’s all about balancing out populations.

If you see an alligator, don’t touch it. Take a few pictures and observe from a distance. In most cases, if you get too close, an alligator maybe become afraid and swim away. Alligators wait patiently for animals to come near and then use all their energy at once to take down their prey. This is one way they conserve energy.
