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).

features

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.

behavior

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 .

Vocalizations

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).

Remarks

  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.
