The Ruby-crowned Tanager is a passerine bird in the tanager family. Also known as Chau, gurundi, chepe, black little fire (São Paulo) and bluebird.
For identification, it is useful to pay attention to the white male under the wings; Red cristinha is almost never visible. The male is black with a narrow bright red band at the top of the head; the female is all brown. It measures about 18 inches.
It feeds on fruits, seeds, flowers and insects in the trees harvested from the average height to the top. Frequents feeders with fruit.
The nest, bowl shaped, is made with branches, vines and leaves, lined internally with fine roots. Its outer diameter is 11 to 13 centimeters, placed in vegetation less than 2 meters high. Eggs, 2 or 3 are rosy with red and brown spots, or even black, and measure 22 of 17 millimeters.
TIE-black can be seen isolated in pairs, groups of 3 or 4 individuals or even in larger packs. The male, when excited, displays the red spot of the head (pileus) and moves the wings showing the white of the lower wing coverts. Species of forest habits, Ruby-crowned Tanager is seen more often when visiting fruit trees on the edges or around woods and coppices. Lives in pairs. It is a bustling bird that frequents the foliage of shrubs and trees, actively moving in search of food.
