White-tailed Nuthatch

Fairly large, bright green parrot endemic to humid tropical lowlands and foothills in northeast Mexico. Uncommon. Found in forests, edges, semiopen areas with scattered tall trees, and forest patches. Most often seen flying over early and late in the day, often fairly high and usually in pairs or loose groups made up of pairs. Best field mark is the pale, ivory-yellow bill that contrasts with the red forecrown. Like other similar parrots, in flight shows a red patch on the back of the wing. Introduced to California, Puerto Rico, Florida, and Hawaii.

Chunky, mid-sized robin-like bird. Males are pale gray and orange, while females are gray-brown. Madagascar endemic that is found in coastal spiny forest and scrub in the southwest. Perches up conspicuously. Song is a variable mix of thin whistles and raspy notes. Paler than Forest Rock-Thrush, with little or no overlap in range. Female similar to female Madagascar Magpie-Robin, but smaller and grayer, without white patch in the wing. 

A small brownish bustard with long legs and neck. May crouch if disturbed but when flushed, explodes noisily into a grouselike flight with whirring wings. Striking white wings with black tips are prominent in flight. Breeding-plumaged males are distinctive with black neck and double V-shaped white collar. Usually fairly quiet and unobtrusive. Found in open plains with shrubs and sufficient ground cover to hide in.
