Spot-backed Antbird

Handsome blue-and-black jay of tropical forests, woodlands, and gardens endemic to west Mexico. Usually in small groups, which can be noisy and conspicuous or very quiet and easily overlooked; often with Yellow-winged Caciques. Around the town of San Blas (in Nayarit, Mexico), appreciably larger Purplish-backed Jay occurs at southern end of its range (and northern end of San Blas Jay’s range). Purplish-backed is deep purplish blue on back and tail, not strikingly two-toned blue-and-black like San Blas Jay, and has bright yellow legs. Voices also very different. Purplish-backed occurs in mangroves and adjacent woodlands in and around town while San Blas Jay occurs in foothill forest of coffee plantations south of town.

A large dark green hummingbird of montane woodlands that often appears black. Within its range, only the Antillean Mango and Green-throated Carib are similar in size and shape. Green-throated Carib and male Antillean Mangos have black, not green, bellies. Female and immature Antillean Mangos have largely gray underparts unlike the Green Mango’s green underparts. Calls include a thin, high twitter, a sharp high "tsip".

Rare bird known only from the Allpahuayo-Mishana National Reserve in the lowlands of northeastern Peru. Like other gnatcatchers, it is mainly gray and white; tail is black with white outer feathers. Distinguished from female Tropical Gnatcatcher by gray breast and broken white eye-ring. Inhabits canopy of forests in areas with sandy soil. Typical song is three “sip” notes followed by a rapid trill.
