American Alligator Populations Continue to Decline into 2015

The American alligator has always been a popular and well known staple in the Florida Everglades. Scientists, however, are starting to fear that the American alligator won’t always be a common presence in Everglades National Park. A species once so prevalent in the park has been declining in population over the years, and even while fewer numbers of alligators are being found and studied in the area, those that are found tend to be much smaller than the generations of gators before them.

Scientists who study gator populations in the Everglades note that today’s gators appear skinny and emaciated, at times like skin and bones. These alligators also grow slower, at only about 2/3 the rate of healthy alligators living in healthy habitats. Worse still, unhealthy alligators in a region that relies so heavily on their presence could mean the presence of an overall unhealthy ecosystem. In some instances, unhealthy alligators could indicate an extremely serious underlying problem.

Some scientists believe that humans are to blame for the declining health of the Everglades, and thus the declining populations and health of many of the species that live there, including the American alligator. The cause of the damage spans decades, starting in the 1950’s when a massive drainage project was started in the Everglades in order to develop the large metropolitan areas of South Florida, such as Miami and Fort Lauderdale.

While the consequences of such a project were not apparent at the start, Everglades wildlife has been effected for years. Scientists believe that the redirecting of water from the Everglades out into the ocean shrank the area of the park by over half and heavily polluted the native waters. While more than $20 billion has been spent on Everglades restoration since to reverse some of this damage, it’s still unclear when, and if, the American alligator population will be able to recover.

Airboat rides through the Everglades with Captain Mitch are the perfect way to spot these magnificent creatures in their natural habitats. Because South Florida has one of the most unique ecosystems in the entire world, alligators are just one of the many species that can be spotted on an Everglades swamp tour. Riders can always expect to see more than a few birds, fish, snakes, and lizards along the way too!

Bull Sharks in the Everglades

Alligators and crocodiles are not the only apex predators that call the Florida Everglades home, though they are undoubtedly the most well known. Many people might actually be very surprised to learn that sharks also live in the Everglades, especially because it’s such a commonly understood fact that sharks need saltwater and are therefore restricted to the world’s oceans.

This fact, however, is a myth, as there are a few species of sharks that are able to adapt to and live in freshwater. Most notably, bull sharks, which have been found in rivers as far north as Illinois. Because many of the wetlands and swamps of the Everglades are connected to the Gulf of Mexico and Atlantic Ocean, it should come as no surprise that bull sharks have been known to find their ways there.

Bull sharks and other freshwater sharks are able to easily adapt to saltwater or freshwater environments because they possess an ability called osmoregulation. While all sharks have this ability, which is simply the ability to maintain a certain concentration of water within the body, bull sharks are different in that they can gradually adjust their kidneys to suit different levels of salinity depending on what kind of water they are in.

Next time you’re out on an Everglades airboat ride, keep your eye out for some fins in the water as well as the usual scales. Because bull sharks are especially prevalent during birthing season, when the secluded rivers of the Everglades provide the perfect protection for young pups, now is the perfect time to spot creatures of all kinds on an Everglades tour.

The Black Vulture is the Everglades’ Least Popular Bird

vulturesWhile the American black vulture is certainly not the most beautiful bird in the Everglades or the one with the best reputation, it might be one of the more interesting birds in not only the Everglades, but the entire world. Because the circling of vultures in the sky can often be a sign that something on the ground has just died and is about to be eaten, black vultures have often been associated with death. But while their feeding habits seem to give black vultures an ominous presence over humans, it is also their feeding habits that make them so unique.

The black vulture is a well known scavenger, and it has often been stated that a vulture will eat “anything.” Their main source of food is carrion, which is the dead and decaying flesh of animals. It’s no wonder these birds are easily spotted hovering above recent road kill, but they have also been known to make a meal out of the living – namely fresh eggs and newborn animal babies.

In areas populated by humans, the black vulture has been known to feed at garbage dumps, and, because they sometimes feed on livestock as well, this particular bird is not too popular among cattle herders and farmers. Whether or not this interesting bird is well-liked by the human population, it plays an extremely important role in the ecosystem of which it lives, as these birds dispose of carrion that would otherwise serve as a breeding ground for bacteria.

The black vulture gets its name from its deep black plumage, featherless grey-black head, and its short, hooked beak. While it is a relatively large bird with a wingspan of up to 5ft, it is actually considered small in comparison to other vulture species, which can get much larger. The black vulture has excellent eye sight and sense of smell, and, because they often find prey by following other vultures, they can often be seen in large groups. The American black vulture can be found in the Southeastern United States down to Central South America, and is protected in the United States under the Migratory Bird Treaty Act of 1918.

While vultures can be found in the populated areas surrounding the Everglades, they are best observed during an Everglades swamp tour. While humans can easily observe them feeding on trash or roadkill in their neighborhoods, airboat tours through the Everglades allow us to truly witness their natural behavior and feeding habits without human intervention.
