Bannerman's Weaver

Small. Olive-green above and banana-yellow below and on throat. Chest smudged olive. Has a bold white eye-ring and a black patch on the face from the eye forward. Found in most forest, scrub, and garden habitats. Song consists of around nine up- or downslurred notes. Call is a strong, two-syllabled “che-u.”

Very local, long-tailed, and social parrot of mountains in northwest Mexico. Feeds in pine and pine-oak forests. Nests colonially in groves of giant aspens, whose soft trunks allow nest cavities to be excavated. Usually found in flocks, of 10–100 birds, less often in scattered pairs; often located by its far-carrying, raucous laughing calls. No similar species in its range; note the red forehead and small red shoulder patches. In flight shows a broad yellow stripe under the wings.

Tiny bird with a strong bill and short tail. Males are glossy blue-black on the head, back, and throat with a bright yellow forehead and belly, and a white undertail. Females are olive-green above with either a yellowish or white belly flanked by yellow depending on region. Found commonly in a variety of habitats from humid forests to mangroves and from agricultural areas to gardens. Often accompanies mixed-species flocks. The most frequently heard vocalization is the “teee-deee” call.
