Sinaloa Martin
Progne sinaloae
Large swallow; very local summer resident in mountains of northwest Mexico. Favors open pine-oak forest, usually with big dead pine snags and cliffs, where nests in cavities. Ranges widely in highlands and foothills, coming to drink at ponds and lakes. Usually seen as singles or small groups, which may associate with other swallows. Male blue-black overall with contrasting white belly. Female similar to several other martins, but clean white belly contrasts more strongly with dark breast.
识别特征
Adult males have dark iridescent blue-black feathers with a contrasting white patch covering the belly to the vent, much like the related Caribbean martin. However, its reproductive situation and different habitat preference supports its status as a species.<p>The adult female and immature form of the Sinaloa martin are very similar to related Progne species such as the Cuban martin, Caribbean martin, and purple martin.

Crow-billed Drongo
Dicrurus annectens
Large dark drongo of open forested environments. Glossy black with a characteristically forked tail. Immature speckled with grayish-white on lower breast and belly. Thick dark bill gives a generally heavier-headed appearance than other similar dark drongos such as Black Drongo, with which it shares parts of its range; also prefers more forested environments than the latter. Aggressive and territorial, particularly during the breeding season, frequently mobbing raptors and corvids with great vigor. Like other drongos, boasts a varied repertoire; songs include a ringing “tsee-goo-gohgee!” Calls include bell-like gurgling notes, harsh chattering, and piercing whistles.

Crimson-collared Grosbeak
Periporphyrus celaeno
Stocky and often rather sluggish bird of tropical forest and edge in lowlands and foothills of northeast Mexico. Usually found as singles or pairs, feeding quietly at all levels in fruiting trees or bushes. Note the thick stubby bill and rather long tail. Adult male is striking: dark overall with a black hood and broad pinkish-red collar. Female is drab greenish overall with black hood similar to male. Immature is like female but with less extensive black hood.

Green-throated Tanager
Stilpnia argyrofenges
Gorgeous cloud forest tanager found in scattered locations along the east slope of the Andes; rare in most of its range. Distinctive male is black and buffy-yellow with a turquoise throat. Female is quite different and might be mistaken for other female tanagers such as Silvery, Black-capped, Green-capped, or Sira; note her bluish head and her yellow back and flanks, which contrast with her white belly. Usually found with mixed-species canopy flocks, often with other tanagers.
