Do Birds See Color?

Have you ever wondered if a hummingbird can recognize colors other than red, or if other birds see color? What about this male Scarlet Tanager?

Woodcock's Sky Dance

It is an ancient music. The mating song of the male American Woodcock. To hear it, step out into the dusk of a quiet spring evening in the Connecticut countryside.

What Birds Can Hear in Songs

What does the Winter Wren hear in a song? It's a long story... What we hear as a blur of sound, the bird hears as a precise sequence of sounds, the visual equivalent of seeing a movie as a series of still pictures. That birds can hear the fine structure of song so acutely allows them to convey... read more »

The Dainty Flamingo?

The Greater Flamingo, an American icon, is as comfortable next to a patio as it is in a tropical lagoon. It is found throughout the Caribbean, in the Galapagos, and from southern Europe across Africa to India. Despite its pencil-thin neck and legs, the flamingo miraculously maintains grace and... read more »

Wrong-way Kingbird

Ornithologists think a glitch in a gene that controls migration in Tropical Kingbirds causes them to fly in exactly the wrong direction. From their Arizona breeding grounds, they head northwest in fall, rather than southeast to their usual wintering haunts in Mexico. Learn more at Cornell's... read more »

Swallows in Winter?
