Nine-banded armadillo

Nine-banded armadillos (Dasypus novemcinctus) are a species of mammal native to the southern United States, and Florida is no exception. Armadillos in Florida are found in many areas, from the Everglades to urban regions. These animals have adapted to a wide variety of habitats, from wetlands and forests to grasslands and scrubs. They can be seen foraging for food during the day or night, and their burrows provide them with shelter from predators. In addition to their unique physical traits such as their hard shell, armadillos also play an important role in controlling insect populations. As such, they are an important part of Florida’s natural environment.
Unfortunately, many people villainize armadillos who root around their yards. Since they enjoy, worms and insects brought to the surface through moist soil, a wet yard attracts them. Preventing overwatering can deter them. If you must water, do so in the morning so the top layer can dry during the day. This will make them less likely to come around at night. You can also use a fence to exclude them. Ensure the fence extends at least 18 inches into the ground to prevent digging. A few small changes can help us coexist with our native wildlife.

Great White Shark

Great White Sharks, Carcharodon carcharias, are the largest predatory fish that inhabit Earth. They can grow to 20 feet and weigh more than 2.5 tons. These endothermic (warm-blooded) fish are found in cool and tropical coastal waters around the world and have been tracked crossing entire oceans. Great White Sharks migrate across wider geographic areas than any other marine animal and have been tracked swimming from Newfoundland to Florida. This sleek grey shark gets its name from its white underbelly. They can travel at speeds up to 15 miles per hour and breach the surface when preying on a food source at the edge of the water.
Great White Sharks are carnivores. Their good sense of smell and ability to sense an animal’s electromagnetic field helps to locate their prey. Food consists of small fish, sea birds, seals, sea lions, and whales. Their 300 triangular teeth make it easy to hold their prey and rip it apart before swallowing the pieces whole. Researchers have learned that Great White Sharks are social animals. The scientists observed single sharks making a kill and sharing their meal with others. Humans are not on the Great White Shark’s menu. While some humans have been severely injured or killed, these incidents are extremely rare. It is now known that Great White Sharks will take a taste and quickly learn that humans are not suitable prey.
Females are larger than males and give birth to live young. During gestation, the mother does not feed her unborn via a placenta. Instead, she provides her young with unfertilized eggs. The new sharks are born as natural predators and will begin eating coastal fish immediately.
There is no accurate population count of Great White Sharks. They are currently listed as Vulnerable (VU A2bd) on the International Union for the Conservation of Nature’s Red List of Threatened Species. Threats include getting caught in fishing nets, inshore habitat degradation, and overfishing. Unfortunately, Great White Shark jaws and fins are often considered commodities. Killing Great White Sharks can be considered an achievement by unknowing or uncaring humans.
Every animal has an important role in our ecosystems. Refuse to buy animals parts. Educate other people about the importance of respecting Great White Sharks and why we need to peacefully coexist with them.

American Mink

The elusive American mink, Mustela vison, is a Florida native. Like otters, they are members of the weasel family and therefore, fiercely carnivorous. Dinner consists of fish, snakes, crabs, crayfish, frogs, insects, and small mammals. Minks are smaller than otters, weigh up to 4 pounds, and are only 1 – 2.5 feet long.

Minks are semi-aquatic animals that live in marshes and along the banks of rivers and streams. They have been spotted in salt marshes near the northern Atlantic and Gulf coasts. The Everglades mink, Neovison vison, is state-designated as threatened. They have been documented in freshwater and saltwater marshes in the southern Everglades, Fakahatchee Strand, and Big Cypress Swamp. There have been no current sightings of mink in the freshwater habitats of northern and central Florida.

In the spring, female minks give birth in their dens of hollowed-out logs or under protective tree roots. The 3-6 kits open their eyes at 25 days, are weaned at 5-6 weeks, and stay with their mother until fall. Bobcats, great-horned owls, and foxes prey on mink. Life expectancy is only 3 years. However, humans are the biggest threat to minks. In addition to hunting mink for oil, fur, and to assure a large fish population in human fishing areas, humans have reduced the minks’ habitat and polluted the waters that supply their food.

Minks are fast and incredibly adept at staying out of the sight of humans. Because they hunt in the late evening, during the night, and early mornings, sightings are rare. FWC biologists are seeking help from the public to track mink distribution in Florida. If you see a mink, please report your sighting here: https://public.myfwc.com/hsc/weasel/Default.aspx

Eastern Cottontail

The Eastern Cottontail (Sylvilagus floridanus) is best known for the white puffy fur on its tail’s underside. Cottontails grow to 14 – 17 inches in length and weigh two to four pounds. Their cotton-like tail is most noticeable when they hop.

Cottontails can be found in woodlands, fields, briar patches, bushy areas, and yards. They are herbivores often seen dining on clover, grasses, and other green vegetation. When greens are not available, Cottontails will seek out young woody shoots and bark. You will often see these solitary rabbits in the early morning or evening.

Breeding can occur any time during the year but happens most often in February through September. In about a month, the mother cottontail will give birth to a litter of 4 – 7 rabbit kittens. Female Cottontails can produce 3-4 litters each year.

Cottontails will stand on their hind feet to look for predators such as hawks, foxes, coyotes, or weasels. When one is spotted, these speedy rabbits can run up to 15 miles an hour and hop distances of up to 15 feet in a single leap.

Coyote

The coyote (Canis latrans) is a medium-sized omnivore. The average size of a coyote in Florida is about 28 lbs. Fossils of their remains have been found in Florida as far back as 2.6 million years ago. Due to the annihilation of the red wolves in Florida, coyotes are thriving. They are also stepping up to the plate to carry out the ecological task previously carried out by the red wolves. The role of a tertiary predator is important in maintaining balance and order in an ecosystem. They do this by regulating the trophic levels below them. If there are too many primary consumers, the vegetation can be depleted, causing soil and water problems. If there are too many secondary consumers, the primary consumer population can deplete, resulting in overgrowth. If prey isn’t available, coyotes adapt by eating vegetation.

February is part of the mating period. I suppose you could say Valentine’s Day is a romantic time for Coyotes as well as humans. After about a 63 day gestation period, the females will give birth. They will have to rely on the male to provide food for the mother and pups. The pups start weaning between April and May. This is done by eating the regurgitated food of their parents. By July, they are eating solid food. They begin hunting in August and will be ready to venture out on their own by December.

Coyotes are often called “song dogs” because of their variety of sounds. People frequently overestimate the number of coyotes in an area due to their singing. The phenomenon of hearing multiples is called the Beau Geste Effect. This term means “fine gesture” in French and comes from a book published in 1924. The story explains how a group of brothers used dead soldiers to give the illusion of several soldiers in an attempt to intimidate approaching forces.

Coyotes get a bad reputation, but with human behavior changes, we can learn to coexist with them. Don’t leave food out for other animals. Walk dogs on a short leash if you know coyotes are around. Secure trash. Keep your yard clear of any debris they could use as a den: secure livestock and their feed. If you see coyotes, make a loud noise to scare them away. As we learn to live with coyotes, we can learn to appreciate the role they play in keeping Florida’s ecosystems healthy.

Coyotes are a perfect example of an omnivore because they will eat almost anything. Their meals consist of plants, berries, dead things, insects (they love bugs), rodents, foxes, small animals of any kind including birds, small livestock, cats and small dogs, and of course, human and pet food!

Unlike wolves, coyotes do not hunt in packs. However, they will hunt with family members until their siblings go on their way.

Why are we seeing more coyotes in Florida? Humans have killed most of the wolves. Because wolves are now nearly extinct in Florida, coyotes have moved in and become king of the hill. They have no natural predators and will coexist in the wild with other animals, including panthers and bobcats. Coyotes love open grassy areas where rodents and other small animals live. Since man has cleared out many forests to make way for ranching and farming, the coyote has a free-range with plenty of food.

An adult coyote weighs 25 to 40 lbs. At times they may appear to be starving and seem very thin. This is their body build. Since they are extremely adaptable to almost any environmental condition and will eat almost anything, there is never any worry about coyotes finding enough food. When coyotes inhabit a new area, their population will grow quickly. Five to six pups may be born in a single litter. Once an area is established, the coyote population will level off.

Can we send them back to their original range? It has been tried in many states for hundreds of years, and the answer is no. Snare traps will most likely catch some other wild animal or someone’s pet before it captures a coyote. Two Florida black bears were found dead with coyote snares around their necks here in Central Florida. If we kill them, coyotes will just have more pups to repopulate the area quickly. Unless we reintroduce their natural predator, the red or grey wolf, and allow nature to take its course through Trophic Cascade, coyotes are here to stay.

What can you do to keep them wild and in the forests or uninhabited areas? We use the same techniques for coyotes as we do for our amazing Florida Black bears. Take in pet food and bird feeders, secure all attractants, scare that coyote if it is in your yard by yelling at it, making loud noises, etc. Never leave small pets outside unattended. Coyotes don’t know the difference between a small cat or dog and any other prey. It’s our responsibility as pet owners to keep pets safe.

Let’s learn to respect nature, and not fear it, to coexist and not destroy it.
