Crest is mostly white, and obvious white frame for the face extends from the rear of the head, around the ear coverts and down to the breast side.

      Lost and found, then lost again? Recently rediscovered hummingbird faces extinction

    The blue-bearded helmetcrest (Oxypogon cyanolaemus) is a spectacular hummingbird. It is aptly named for the blue streak of feathers on its chin and a pointed crest on its head resembling a knight’s helmet.

    Equally spectacular to the species’ physical appearance is its physical disappearance and reappearance.

    No one had seen a single living blue-bearded helmetcrest since 1946, and the species was known only from preserved museum specimens. But that all changed last month when researchers rediscovered the bird in the mountains of Colombia. ...

     The blue-bearded helmetcrest (Oxypogon cyanolaemus) is a species of hummingbird endemic to the Santa Marta Mountains in northeastern Colombia. It has elongated purply blue throated feathers, which assemble in the form of a beard and a prominent white crest. The white frame from the face extends from the rear of the head, around the ear coverts and down to the breast side.

    The blue-bearded helmetcrest was formerly considered to be a subspecies of what was known as the bearded helmetcrest (Oxypogon guerinii). The blue-bearded helmetcrest was promoted to species status when the bearded helmetcrest was split into four species based on a study of biometric and plumage data published in 2013. The nominate subspecies was renamed the green-bearded helmetcrest.[3][4]

    It is an extremely rare hummingbird which was known only from 62 museum specimens with the most recent specimen taken since 1946. Surveys during 1999-2003 failed to detect the species ...

     Le Colibri à barbe bleue ou colibri à casque bleu (Oxypogon cyanolaemus) est une espèce de colibri endémique des montagnes de Santa Marta, dans le nord-est de la Colombie. Il possède des plumes allongées à gorge bleue pourpre, qui s'assemblent sous la forme d'une barbe et d'une crête blanche proéminente. Le cadre blanc de la face s'étend de l'arrière de la tête, autour des couvre-oreilles et jusqu'au côté de la poitrine1.

    Il s'agit d'un colibri extrêmement rare qui n'était connu que de 62 spécimens de musée, le dernier ayant été prélevé depuis 1946. Les enquêtes menées entre 1999 et 2003 n'ont pas permis de détecter l'espèce. Une brève enquête menée en février 2007 et en décembre 2011 n'a pas permis de détecter l'espèce, mais les efforts d'enquête n'ont jamais été suffisamment approfondis pour inscrire cette espèce sur la liste des espèces en danger critique d'extinction (possiblement éteintes)2. En mars 2015, des chercheurs de la fondation ProAves ont redécouvert le colibri à barbe bleue en documentant les feux allumés par les agriculteurs locaux qui menacent aujourd'hui l'espèce3 ...
