Characteristics
It's about 18 centimeters. It is a bird with a gray body, black head, throat and neck. When young its color is olive green. It has a soft and soft chirp very similar to that of the velvet bill (Schistochlamys ruficapillus). According to recent discoveries, sexual dimorphism does not exist. In the brand new edition (2011) of the Birds of Brazil - Pantanal and Cerrado guide, only a single adult form appears. Other older books present the female as olive green, but today this form of the bird is considered to be that of the young.
