Zanate Frenteterciopelo

Identificación

The male velvet-fronted grackle grows to about 22 cm (9 in) and the female about 19 cm (7.5 in). Both sexes are entirely black, with a slight bluish gloss on the dorsal surfaces. The feathers at the front of the crown are very short and dense, giving a velvet-like appearance at close quarters. The beak is short, conical and pointed, the iris is dark and the tail is long and somewhat rounded. The calls produced include a crackling "chack" and a whistling "cheziit", and the song, sometimes sung at dusk from a perch, is a moderately-musical rapid gurgling sound. This species could be confused with the shiny cowbird (Molothrus bonariensis), but their calls and habits are quite different.

Resident species

Comportamiento

This species often congregates with others of its kind in small groups of up to about twenty birds. Sometimes these coalesce with groups of tanagers and caciques. The birds move noisily through the canopy, foraging high and low, and sometimes hopping around on floating vegetation on lakes. The diet includes insects such as winged ants and beetles but is poorly described. In Guyana it breeds in March, in Ecuador in September and in Bolivia in October and February.
