Chestnut-crowned Sparrow-Weaver

A small warbler with a dark cap and eye-stripe and a yellow eyebrow. Strongly yellow below, dark chestnut brown above. Bill and legs pale. Found in mossy forest above 1200 meters of elevation. Very similar to Island Leaf Warbler, but yellowish rather than light gray below, with pale bill and legs. Song a tinkling warble, but more commonly heard giving quiet “tzik” call.

Small and rotund with intricate brown, black, and white patterning. Some striking variation in plumage across range. Most males, including those in the eastern U.S., have bold black and white head pattern and heavy white spotting on belly. In Mexico, males can be entirely cinnamon-colored below and have a fully black head; some might have a white eyebrow or a dark chest band. Females are more consistent throughout range: look for buffy throat and eyebrow. Pairs or small groups are found in scrubby fields and brushy woods. Usually on the ground, but occasionally perches in trees when singing. The only quail native to the eastern U.S., where populations are declining sharply. Listen for distinctive “bob-WHITE!” whistle.

Stocky goose that inhabits rocky coastlines, lagoons, and tidal flats. Striking white head, black throat, and petite pink bill. Blue-gray body with intricate black-and white bars, a white tail, and bright orange legs. Face sometimes stained orangish-brown. Juvenile has a gray head, but still shows white tail. Breeds on marshy tundra and winters in small flocks on coastal waters. Rarely seen outside Alaska.
