Turquoise-crowned

Common name: Turquoise-crowned Hummingbird (female photographed only)
Scientific name: Cynanthus doubledayi
Clades: Trochilini - Emeralds
Endemic to Mexico

The Turquoise-crowned Hummingbird is about 8–10 cm (3.1–3.9 in) long. It weighs only 3–4 grams (10 to 14 oz), with the male weighing slightly more than the female.

Turquoise-crowned Hummingbirds have brilliant colors, dark tails, and mostly red bills. The species is endemic to Mexico, mainly along the Pacific coast from Guerrero to Oaxaca. Among its habitats are arid thorns, tropical deciduous, galleries, and secondary forests. Forests with pine-oak trees and grassy slopes occasionally host this species. Elevations generally range from sea level up to 2,200 m (7,200 ft), but they can reach more than 3,000 m (9,800 ft). When seen from a distance, the male appears all dark, but in the right light, it glistens cobalt blue. In females, the underside is grayish-dusky with a prominent pale stripe behind the eye.

This species used to be called Doubleday’s Hummingbird and was considered a subspecies of the Broad-billed hummingbird.
