Family and Species Gallery
Class: Aves (birds) - Birds are the only organisms with feathers. They are endotherms, maintaining a nearly constant body temperature. They have a hard bill but no teeth. A gizzard, which functions to grind food, is present in the digestive tract. Fertilization is internal. A nest is built in which the hard-shelled eggs are deposited and incubated.
Order: Pelecaniformes - Tropic birds, pelicans, gannets, boobies and darters are medium-sized aquatic birds. They have long bills and a throat pouch to aid in the capture and eating of fish. These birds nest together in large numbers. All four of their toes are webbed together to help them move through the water.
Family: Pelecanidae (Pelicans) - Pelicans are large, stout aquatic birds. They have elongated and flattened bills and a long neck. There is a huge pouch on their throat. The head rests on the shoulders when the bird flies. They have a straight line flight pattern. The birds float like bouys while they are swimming.

Family: Ardeidae (Bitterns, Herons, and Allies) - Herons and bitterns are aquatic and wade at the water's edge. They have long legs and necks. The bill is pointed (like a spear) for capturing food. They fly with their heads resting on their shoulders, in an "s" pattern and with the legs sticking straight out behind them.
