White-breasted Whistler

Attractive duck with distinctive triangular head; forehead slopes seamlessly into the long bill. Males are white-bodied with black chest, reddish-brown head, and red eye. Females are dull grayish-brown with unique head profile and dark brown eye. Breeds in lakes and marshes. Winters in any large body of water with submerged aquatic vegetation on which to feed. Dives frequently, searching for vegetation and invertebrates. Often gathers in large flocks in nonbreeding season.

Widespread but uncommon forest hawk of tropical America. Adults are mostly gray, darker on crown and upperparts, with two pale tail bands and rufous thighs that are often hidden from view. Belly is tinged rufous and faintly barred in the southern part of its range. Immature looks remarkably like a forest-falcon, but note its yellow eye and lack of dark crescent on face. Overlaps with the similar Rufous-thighed Kite in parts of South America. Bicolored Hawk is larger, lacks a vertical stripe on the throat, usually stays inside forest, and almost never soars. Feeds mainly on birds and is generally quiet and elusive. Birds from central and southern Chile as well as adjacent parts of Argentina are now considered a separate species, Chilean Hawk.

Large red-headed woodpecker of tropical forest in lowlands and foothills; also in pine-oak forest of lower mountain slopes. Red head (with black forehead and throat on female) is often more squared than Lineated. Juvenile Pale-billed has black face with white cheek stripe, very like Lineated, but soon attains red head and usually travels with adults. All plumages of Pale-billed have a white V on the back, compare Lineated. Loud double-rap drum distinctive; drum in West Mexico often longer, but still very slow-paced.
