Peregrine Falcon

Though the peregrine falcon is certainly not exclusive to South Florida, the species is one of the Everglades’ greatest hunters. The name peregrine falcon literally means “wandering falcon”, and the species has up to nineteen listed subspecies, though one or two of these are currently up for scientific debate. They are members of the raptor family, and though not great in size – caping out at around two pounds and a couple of feet in length – they are one of the most feared and respected birds throughout the world.

This well known bird of prey can be found on six of the seven continents and is quite versatile in its habitat. Because of this, it is one of the most widespread species of all birds, and is only absent from areas of extreme cold, extreme altitude, and extreme rainfall. In fact, only the rock pigeon is more widespread than the peregrine falcon, a species which is actually one of the later’s most desirable prey. Like the rock pigeon, peregrine falcons are becoming more and more common in populated cities, though they do prefer low mountain ranges, river valleys, and open coastlines.

The peregrine falcon is the single fastest species that can be found in the entire animal kingdom. In fact, with the highest measured speed of a peregrine falcon coming in at 242 mph, these amazing birds can beat out most top of the line sports vehicles as well. The peregrine falcon, however, only reaches these extreme speeds during a stoop, which is a hunting tactic in which the raptor first climbs to a high altitude before diving steeply towards its prey. And, for the estimated 1,500-2,000 species of smaller birds that the peregrine falcon feeds on worldwide, being caught in this predator’s line of site while hunting is an almost sure sign of impeding death.

While notable for its great speeds, the peregrine falcon is perhaps most famous for its trainability as a falconry bird. In this hunting tactic, a trained falcon stalks and kills its prey, but instead of eating its capture itself, it returns its victim willingly to its human owner. The earliest accounts of the practice of falconry occurred in 2,000 BC, and are not only evidence of the interesting relationship that has existed between human beings and these birds for centuries, but are strong evidence for the extreme level of intelligence these birds possess as well.

For your chance of spotting a peregrine falcon in the wild, as well as for other amazing bird-watching opportunities in South Florida, there’s truly nothing better than an airboat tour through the Everglades. No one knows the area better than an experienced Florida swamp tour guide, and you’ll find just that with Captain Mitch and his friendly crew.

The Dangers of Red Tide

If you live in Florida, there is a good chance you are familiar with red tide – especially if you have been in Florida in the last decade or so, as three major red tides have occurred in recent years along the Gulf of Mexico coastline. This colorful phenomenon is not only highly noticeable when it occurs in local waters, but it also has a large affect on the local ecology and economy as well.

Despite its somewhat morbid appearance, giving seawater the distinct tinge of a deep blood-red, red tide is actually the result of something somewhat unexpected. When certain types of algae, called dinoflagellates, are present in high amounts, it causes what is known as an algal bloom. It’s important to note, however, that not all algal blooms will result in a red tide, as not all types of algae are red or brown in color, and oftentimes their concentration is not actually high enough to cause a change in the water’s appearance.

It also important to note that the title of “red tide” is not entirely accurate, especially as the phenomenon has nothing to do with the tides at all. Furthermore, harmful algal blooms can occur just as easily with dinoflagellates that are not red in color, and which in fact blend in so well with the natural coloring of the water that they are almost entirely undetectable. It is these algal blooms that are perhaps the most dangerous, because their presence is much less obvious while their affects can be just as disastrous.

But what makes algal blooms so dangerous? In terms of direct causes to the local wildlife, the affects can be quite deadly. Karenia brevis, the microorganism which is present in most Florida cases of red tide, produces brevotoxins that are highly poisonous to marine life. These toxins build up in seagrass and sediment, which is then fed on by primary consumers and eventually eaten by predators, negatively affecting and killing wildlife at all stages of the food chain.

While it’s not uncommon for red tide and other algal blooms to kill off large populations of fish and manatees, these harmful affects reach human beings in the area as well. Economically, the affects on marine life cause disruptions to fisheries and local restaurants, as animals containing brevotoxins are unsafe for human consumption. Furthermore, fishermen, beachgoers, and boaters can be affected simply through air exposure, as certain algal blooms can cause eye irritation and respiratory problems, especially in those with respiratory conditions already present.

Fortunately, no major red tides have occurred in South Florida during the 2015 season, and the coastlines and estuaries of the Everglades can easily be enjoyed on an exciting airboat tour. To view the Everglades ecosystem at its best, schedule a Florida swampland tour that the whole family can enjoy today.

How Do Sharks Survive in Freshwater?

Most people associate sharks with saltwater and the oceans, and rightly so. However, while saltwater environments are certainly where the great majority of shark species can be found, this is not to say that they are completely unable to survive in freshwater environments as well. In the United States alone, sharks have been spotted in the Mississippi river as far north as Illinois, as well as in the ocean-connected rivers that are so prevalent throughout South Florida and the Everglades.

This is not to say that you will find just any species of shark making its way into the world’s freshwater rivers. In fact, there is one shark in particular who seems to be found in these areas more than any other – the bull shark. Furthermore, this fact can be particularly scary when you consider that bull sharks are responsible for more human deaths than any other species of shark in the world. Not only must swimmers be wary of alligators when entering a Florida river, but if said river is also connected to the ocean, swimmers must also be careful to avoid bull sharks as well.

Scientists are still not entirely sure what makes this special characteristic almost exclusive to this single species of shark. All species of sharks must maintain a certain concentration of salt within their bodies, as salt prevents their cells from rupturing which in turn causes bloating and death. As soon as a shark enters freshwater, the salt concentration within their body becomes diluted, which is why the great majority of sharks will never even enter freshwater at all, or if they do, will leave it almost immediately.

The fact that bull sharks can live in freshwater is not because they do not possess the same need to maintain a certain salinity level as other sharks. Bull sharks still need to maintain their salinity levels, but have developed a special ability within their kidneys to continuously recycle and retain the salt that they absorb. And while it is not yet known how or why they developed this ability, it does seem to give them a competitive advantage when it comes to feeding and breeding, allowing them exclusive access to certain prey as well as a safe haven for newborns. However, because freshwater environments still do not appear to be preferable for bull sharks, it is clear that the disadvantages of such environments still outweigh the advantages.

For your chance to see two of planet earth’s most fearsome predators in the same environment – alligators and sharks – take an airboat ride through the Everglades today. Not only are airboat tours a safe way to observe these wild animals from a comfortable distance, but they are a great way to explore everything else that the Everglades has to offer as well.

The Difference Between Centipedes and Millipedes

Of all the creepy crawlies that can be found in southern Florida, perhaps two of the most seen and hated are centipedes and millipedes. And while the two species are often discussed interchangeably, they are actually two very different types of arthropods – and the differences go far beyond just the number of legs that they have.

First, it is important to point out the similarities that these two types of arthropods have. For instance, they are both from the group Myriapoda. They also both have segmented bodies, numerous legs, and breath through spiracles, which are openings on the surface of their bodies that lead to their respiratory systems. While the two species are from the same group in the animal kingdom, it’s important to note that there are more than 13,000 species within the group Myriapoda, with an almost infinite amount of variation between them.

Centipedes are further classified into the class of Chilopoda, while millipedes are placed into the class of Diplopoda. Species in the class of Chilopoda are flexible and have flattened appearances, while those in the class of Diplopoda are more rigid and sub-cylindrical in shape. It’s also important to note here that neither centipedes nor millipedes are insects, though they are often mistakenly referred to as such. Insects are classified as only have three pairs of legs, one pair on each segment, while both centipedes and millipedes have many segments, with one or two pairs of legs on each, respectively. There is also no set number of legs with centipedes and millipedes, and there will usually be a lot of variation between specific species of each.

You’ve probably seen both centipedes and millipedes inside your home at some point, especially if you live in Florida, where both are considered to be household pests. You probably find millipedes to be far more innocent than centipedes, however, as they are incredibly slow moving and generally harmless. Their legs are also not visible unless you get very close to them, they are not capable of biting, and they feed only on decaying organic matter. While understandably a nuisance inside your home, these creatures are considered a very ecologically important part of the environment.

Centipedes, on the other hand, are a different story. Even while having fewer legs than millipedes, they are incredibly fast movers, a fact which is accentuated by the fact that their legs veer off from the sides of their bodies and trail backwards and are highly visible in comparison to the legs of millipedes. Centipedes also have to be handled carefully because they bite, releasing a venom into their prey which in rare cases can cause allergic reactions in humans.

You may think you’ve seen enough of these critters in your houses but we promise, both centipedes and millipedes are a lot more interesting in the Everglades, where on an airboat ride you run the chance of spotting a few alongside alligators, snakes, and birds in every color of the rainbow. Don’t miss your chance to experience the Florida Everglades on a safe, yet thrilling airboat tour today.
