Red-necked Tanager Tangara cyanocephala
Brazilian name: saíra-militar
The Red-necked Tanager is found along the east coast of Brazil from Ceará to Rio Grande do Sul and into northern Argentina.
They are found generally in the Atlantic Rain Forest, on forest borders but in scrub in the north east of Brazil.
It is a very colourful bird with cobalt blue crown and chin, black forehead, red “scarf”, a turquoise line round the eyes and above the forehead, green underparts, black wings with broad green edging and a yellow-orange line on the wing coverts.
Photos 5 to 8 are from the Serra de Baturité, Ceará and are of the sub-species T. c. cearensis. These are slightly smaller than the nominate and note also the turquoise-blue at the rump and base of the tail which is absent in the nominate.
The female in photos 6 and 7 is duller with a mantle streaked black and dull yellow. Photo 8 is of a young bird.
They feed at the top of fruiting trees occasionally dropping down to pick berries of bushes.
There are recordings on xeno-canto, a distribution map from NatureServe and additional information available via Avibase. There is a page in Portuguese on Wikiaves.
