Short-tailed Drongo

Beautiful small bunting of lowlands and foothills; endemic to west Mexico. Occurs in brushy woodland and edge, adjacent weedy fields, and open grassy areas. Often in small groups, feeding on roadside grasses and flushing up with brilliant blue flashes. Also feeds at all levels in fruiting trees and bushes. Male unmistakable: electric turquoise blue and green above; rich yellow below with a burnished orange breast. Female duller overall: greenish above and yellow below, with a bluish tail. Female brighter yellowish below than slightly larger female Painted Bunting.

A tiny, brightly colored bird with a sharp bill. The back is olive-green, the wing blackish with white fringes, and the underparts yellow. Local and uncommon in savanna, ranging from moist Guinea savanna to dry thorn savanna. Usually in pairs or small flocks. Similar to Sennar and Forest Penduline-Tits, but much brighter: yellow rather than buffy below, and with white edges on the wing feathers. Vocalizations include a series of whistles in an up-and-down pattern and a quick series of buzzy notes. 

This hummingbird is found in humid forest in mountainous regions of eastern Venezuela, the Guianas, and northern Brazil. Plumage is bright green with a coppery rump and tail, and belly ranges in color from pale gray to buff. Occasionally seen in lowlands, where it is perhaps just a seasonal visitor or wanderer. Formerly considered to be a subspecies group of Green-bellied Hummingbird.
