Alligators are freshwater and slow moving rivers and have the blunt, square nose.
Crocodiles are found in salt water and have the pointy nose
Great Blue Heron: Whether poised at a river bend or cruising the coastline with slow, deep wingbeats, the Great Blue Heron is a majestic sight. This stately heron with its subtle blue-gray plumage often stands motionless as it scans for prey or wades belly deep with long, deliberate steps. They may move slowly, but Great Blue Herons can strike like lightning to grab a fish or snap up a gopher. In flight, look for this widespread heron’s tucked-in neck and long legs trailing out behind.
Pied-billed Grebe: Part bird, part submarine, the Pied-billed Grebe is common across much of North America. These small brown birds have unusually thick bills that turn silver and black in summer. These expert divers inhabit sluggish rivers, freshwater marshes, lakes, and estuaries. They use their chunky bills to kill and eat large crustaceans along with a great variety of fish, amphibians, insects, and other invertebrates. Rarely seen in flight and often hidden amid vegetation, Pied-billed Grebes announce their presence with loud, far-reaching calls.
Wood Stork: A large, white, bald-headed wading bird of the southeastern swamps, the Wood Stork is the only stork breeding in the United States. Its late winter breeding season is timed to the Florida dry season when its fish prey become concentrated in shrinking pools.
