Types of Diving Birds in Florida
Florida is home to a diverse range of diving birds, each with its own unique and behaviors. These birds have adapted to their aquatic lifestyle, enabling them to thrive in Florida’s coastal areas, lakes, and rivers. Let’s explore three fascinating diving bird species found in Florida: the Brown Pelican, Double-crested Cormorant, and Anhinga.
Brown Pelican
The Brown Pelican is a remarkable diving bird commonly spotted along Florida’s coastlines. With its large body and wingspan, it is an impressive sight to behold. This bird has a distinctive appearance, with a long bill and a pouch that hangs from its lower mandible. The pouch is used to scoop up fish while diving from the air.
Unlike many other diving birds, the Brown Pelican does not dive from great heights. Instead, it glides low over the water, scanning for fish below. Once it spots its prey, it folds its wings and plunges headfirst into the water, using its sharp beak to catch fish. The Brown Pelican is known for its graceful and efficient diving technique.
Double-crested Cormorant
Another notable diving bird found in Florida is the Double-crested Cormorant. This bird has a sleek body and a long, slender neck that allows it to swiftly navigate through the water. Its name comes from the distinctive double crest of feathers that appear on its head during the breeding season.
The Double-crested Cormorant is an expert fisherman, using its webbed feet to propel itself underwater in search of prey. It can dive to impressive depths and remain submerged for several minutes at a time. This bird has a voracious appetite and can consume large quantities of fish in a single feeding session.
Anhinga
The Anhinga, also known as the “snakebird,” is a fascinating diving bird that can be found in the wetlands and swamps of Florida. It has a slender body and a long, snake-like neck that it uses to spear fish underwater. Unlike other diving birds, the Anhinga lacks waterproof feathers. Instead, its feathers are permeable, allowing them to become saturated with water. This unique adaptation helps the Anhinga dive deeper and stay underwater for longer periods.
When hunting, the Anhinga swims slowly beneath the surface, patiently waiting for its prey. Once it spots a fish, it rapidly extends its neck forward and impales the fish with its sharp beak. The Anhinga then flicks its head back, tossing the captured fish into the air, and catches it headfirst before swallowing it whole.
