Checker-throated Woodpecker
Chrysophlegma mentale
Ornate medium-sized woodpecker. Moss-green with blood-red wings and neck. Back edge of head and neck are brightened by a sunny yellow crest. Black-and-white “checker” throat is not particularly obvious. Prefers mature lowland and hill forests; seldom seen in secondary growth or sparsely-vegetated edge. Typically forages at mid-levels of forest, frequently singly but also in mixed flocks or pairs. Gives loud, insistent “nyeh” notes and a strident “choo-yik!”

Yellow-headed Amazon
Amazona oratrix
Scarce and local large green parrot of tropical lowland savannas and semiopen areas with forest patches and big trees (but often seen in cages). Like many parrots, usually seen in pairs, not mixing with other species. The head of Mexican birds has extensive yellow (less so on immatures) and the bill is pale. Birds in Belize and Honduras have less yellow on the head. This species is often trapped for the pet trade, which means it has been eliminated from much of its historic range.

Cuban Crow
Corvus nasicus
A large, black gregarious species of open woodlands, palm savannahs, and human settlements (including agricultural areas and garbage dumps) near woodlands; often found in flocks of up to fifty birds. The similar Palm Crow has a much shorter bill with extensive feathering on top. The Palm Crow also has a flat, harsh “raaah” unlike the Cuban Crow’s “whih waaa” call with the first note inflected upward and the second note downward. Cuban Crows also have a number of shrieking and harsh burbling noises.
