Turquoise tanager
Template:Short description Template:Speciesbox The turquoise tanager (Tangara mexicana) is a medium-sized passerine bird in the tanager family Thraupidae. It is a resident bird from Trinidad, much of Brazil, Colombia, and Venezuela, and south to Bolivia. Despite its scientific name, it is not found in Mexico. It is restricted to areas with humid forest, with its primary distribution being the Amazon. It was formerly treated as being conspecific with the white-bellied tanager which is found in the Atlantic Forest of eastern Brazil.
It occurs in forest, woodland, and cultivation. The bulky cup nest is built in a tree or shrub, and the female incubates three brown-blotched grey-green eggs.
These are social birds usually found in groups. They eat a wide variety of fruit and also take insects and other arthropods,<ref>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref> often gleaned from twigs.
TaxonomyEdit
The turquoise tanager was formally described in 1766 by the Swedish naturalist Carl Linnaeus in the 12th edition of his Systema Naturae under the binomial name Tanagra mexicana.<ref>Template:Cite book</ref> His description was principally based on Mathurin Jacques Brisson's Le tangara blue de Cayenne that he had described and illustrated in 1760.<ref>Template:Cite book</ref> The type locality is Cayenne in French Guiana.<ref>Template:Cite book</ref> The turquoise tanager is now placed in the genus Tangara that was introduced by Brisson.<ref name=brisson>Template:Cite book</ref><ref name=ioc>{{#invoke:citation/CS1|citation |CitationClass=web }}</ref>
Four subspecies are recognised:<ref name=ioc/>
- T. m. vieilloti (Sclater, PL, 1857) – Trinidad
- T. m. media (Berlepsch & Hartert, 1902) – east Colombia and Venezuela
- T. m. mexicana (Linnaeus, 1766) – the Guianas to central Brazil
- T. m. boliviana (Bonaparte, 1851) – southeast Colombia to east Ecuador, east Peru, west Brazil and north Bolivia
The white-bellied tanager (Tangara brasiliensis) was formerly treated as a subspecies.<ref name=ioc/>
DescriptionEdit
.jpg){kind=link}
Adult turquoise tanagers are Template:Cvt long and weigh 20 g. They are long-tailed and with a dark stout pointed bill. The adult is mainly dark blue and black, with turquoise edging to the primaries. Most races have yellow lower underparts, but this is paler, more cream, in the nominate subspecies found in north-eastern South America. The Trinidadian race, T. m. vieiloti, has a darker blue head and breast and more vividly yellow underparts than the mainland taxa. Their song is a fast squeaky chatter tic-tic-tic-tic-tic.
