They are found in more varied habitats than any other owl in North America.
What we hear as a blur of sound, the Winter Wren hears as a precise sequence of sounds, the visual equivalent of seeing a moving film as a series of still pictures.
The harsh call of a silvery-white seabird rips the air.
Before the boat leaves, climb the stairs and step out on the observation deck where you can enjoy a mini-birdwatching cruise. Why does the American Dipper dip?
The bills of young birds are not crossed at hatching, but cross as they grow.
The people went hungry because the clams lay hidden under water. But beneath the waves, with its flipper-like wings partly extended, it is a streamlined, masterful swimmer. Only the Glaucous-winged Gull nests in the Pacific Northwest, so for months, gull-watching has been pretty tame. Not really a hawk at all, the nighthawk is closely related to the more fully nocturnal nightjars, such as the Whip-poor-will of eastern North America.
This is the only North American raptor to feed exclusively on fish. The parent Bald Eagles may react by calling from a tree, or they may have to descend to the ground, to tend to and encourage their young to take flight again. Bluebirds nest in tree cavities, but clear-cutting and the removal of snags have decreased their natural nesting sites. Killdeers lure predators away from their nest by calling loudly while appearing to limp and drag a wing. To compensate, these birds move their heads.
A Peregrine attacks a flock of shorebirds, igniting a breathtaking aerial display.
Only a few weeks after young Bald Eagles fledge from their nests, the parents leave the area as well. The nests are bits of gravel, debris, and dried vegetation or sticks, often next to a wall or chimney. Look high into the top branches of a Douglas fir tree, and you may see a Bald Eagle, our national symbol.
It appears that its head and feet are linked. When a hawk-predator chases a smaller bird, the hawk focuses on the strongly contrasting feathers of its prey.
