Family : Hummingbirds (Trochilidae)
Genre : Cynanthus
Type : Blue-faced broad-billed hummingbird
Scientific name
Cynanthus doubledayi
( Bourcier , 1847)

The blue-faced broad-billed hummingbird ( Cynanthus doubledayi ) or Doubleday broad-billed hummingbird is a species of bird from the hummingbird family (Trochilidae). The species is endemic to Mexico . The IUCN assesses the population as Least Concern (not endangered).


The blue-faced broad-billed hummingbird reaches a body length of about 8 to 9 centimeters. The straight beak is red with a black tip. The front upper head of the males glitters turquoise blue, the throat even more intense violet blue. The underside shimmers blue-green. The under-tail-coverts are blue-black with pale gray, thin hems that can hardly be seen in the wild. The females resemble the blue-throated broad-billed hummingbird , but are slightly smaller and the tail appears dull gray-green, which stands out clearly from the emerald-green back.


Not much is known about the behavior of the hummingbird, but it is believed to be similar to that of the blue-throated broad-billed hummingbird.

distribution and habitat

They live in dry to semi-arid bushy forests, in scrub and semi-open areas with isolated trees. They can be found at altitudes from sea level up to 900 meters on the Pacific slopes from western Guerrero via Oaxaca to eastern Chiapas .


Their calls sound like a dry chatter, similar to that of the blue-throated broad-billed hummingbird. When they have settled on branches, they often emit a lively chik, chik, chick, chik, chik , with particular emphasis on the first and last notes.

Etymology and history of research

Jules Bourcier described the blue-faced broad-billed hummingbird under the name Trochilus Doubledayi . Bourcier suspected that the type specimen came from the Río Negro . William Swainson introduced the new genus Cynanthus in 1827 for the blue-throated broad-billed hummingbird , which was later assigned to the blue-faced broad-billed hummingbird. This name is a Greek result from "kyanos κυανος " for "dark blue" and "anthos ανθος " for "blossom". It is unclear who should be honored with the species name "doubledayi", as Bourcier did not provide any information. If one follows Étienne Mulsant , who, like Bourcier, came from Lyon and also published with him, then the name is dedicated to Edward Doubleday (1810–1849).

  1. The first description probably appeared in The Philosophical magazine . However, it cannot be ruled out that it first appeared in The Zoological journal from the same year.
  2. Other sources name his brother Henry Doubleday (1808–1875), to whom the name is dedicated. Since Bourcier used a manuscript by George Loddiges (1786–1846), this cannot be ruled out either.
