Burnished-military


Burnished-military

Tangara cyanocephala, also known as Burnished-of-handkerchief, had left-necked-red, soldier and verdelim (NE), is a passerine bird in the Thraupidae family.
It has three subspecies of subtle diagnoses, often even questionable, based on size, extent of red stripe on the neck, the color on the head and color of supracaudais coverts (the latter most notable character). Extreme (T. c. Cyanocephalae T. c. Cearensis) are well differentiated, however T. c. Corallina may just be a intergradante population, and not a valid taxon, which points to the need for a group of taxonomic revision.
Tangara cyanocephala cyanocephala: inhabits from the south of the Holy Spirit to Rio Grande do Sul, more Paraguay and northern Argentina (Misiones);
Tangara cyanocephala coral: the Pernambuco coast to the Holy Spirit; It is distinguished from the noun form to be, on average, slightly lower; the track in the neck is a red a little paler; the yellow bar on the wing is narrower and lower parts are yellowish.
Tangara cyanocephala cearensis: Serra do Baturité, Ceará. Critically Endangered. Differs from the nominal form and prior to have a crown of a blue-purple, black feathers on top of the canyon between the red stripe and the blue end of the throat, and especially for having feather light blue in coverts supracaudais .
