To celebrate America's 250th birthday, we at the U.S. Fish and Wildlife Service are highlighting the incredible wildlife that calls this beautiful country home. From American icons to subtle specialists, join us as we highlight seven species each week: one species for each of the 250 days leading up to America's 250th birthday. 

American eel (Anguilla rostrata)

The American eel has a mysterious life cycle that carries out across thousands of miles - from freshwater rivers to the open ocean. Born in the Sargasso Sea region of the Atlantic, eels migrate to rivers and streams across eastern North America where they may live for decades before returning to spawn once.

American kestrel (Falco sparverius)

The American kestrel is North America's smallest falcon, easily recognized by its colorful plumage. These raptors hunt insects, small mammals and more from perches along open fields and roadsides. This time of year, they're claiming territories and preparing to nest.

Elk (Cervus canadensis)

The elk is known for its bugling calls, large size and the male's massive antlers. This time of year, elk herds begin to shift from wintering grounds to higher elevations as snow melts and vegetation emerges.

Eastern bluebird (Sialia sialis)

The eastern bluebird has brilliant blue feathers and a warm rusty chest. This time of year, bluebirds may already be building nests and defending territories as they forage for insects, fruit and seeds.

Bottlenose dolphin (Tursiops truncatus)

The bottlenose dolphin is an intelligent and social marine mammal found along coasts and in some bays and estuaries. This time of year, dolphins are moving inshore to feed as temperatures rise, following schools of fish.

Eastern screech owl (Megascops asio)

Eastern screech owls are small but mighty, known for their impressive camouflage and haunting calls. These nocturnal hunters can be gray or reddish and are found in woodlands across the eastern United States. Right now, it's breeding season and pairs are actively defending territories and delivering food to mates.

Five-lined skink (Plestiodon fasciatus)

The five-lined skink is a sleek, speedy lizard found in forests, woodlands and rocky areas of the eastern United States. Juveniles have a striking bright blue tail that helps distract predators. This time of year, they're emerging from winter dens and seeking out sunny spots.
