Red-billed Partridge

Remarkably plain brown warbler whose most outstanding features are a finely speckled throat and a white outer tail. Found in the canopy of acacia trees at middle and high elevations. Slow-moving and inconspicuous. Usually seen singly or in pairs. Not very vocal, but does give a simple whistled song and ratcheting calls. Somewhat similar to Garden Warbler, but darker below, with white edges to the tail. Could also be mistaken for female Eurasian Blackcap, but lacks its rufous cap.

Dark-bodied with a creamy face. About the same size as Mallard. Overall color is darker than female Mallards and paler than American Black Duck. White bars in wing are very narrow, and may not be noticeable. Males have bright yellow bill, females have duller olive bill. Inhabits wetlands of Florida and coastal areas from Louisiana to Mexico.

A bright and attractive small warbler with many virtually identical relatives. Breeds in foothill and montane forests, where it favors areas with a dense understory. Descends into lower elevations in the winter, when it often moves around with mixed flocks. Bright green above and yellow below, with a gray-and-black-striped crown and a bright yellow eyering; note intermediately strong crown patterning and distinct yellow eyering, often weak but not broken above the eye. Song is a series of lively whistles and chirps uttered in discrete bursts.
