Bird name: Shiny Cowbird
Latin: Molothrus bonariensis
Other: Vira-bosta (Br) • Tordo (Es), Tordo común, Tordo renegrido
Family: Icteridae • Cowbirds

The Shiny Cowbird is one of a few entirely black birds to be found in Brazil. The photo above may be of a female - the adult male is jet black and shiny.

The Shiny Cowbird’s range covers much of Latin America and has recently extended into Chile and Florida.

It’s usually seen in groups but not always. It tends to walk around on the ground and looks more relaxed than the male Ruby-crowned Tanager. The Chopi Blackbird has a more peaked head and grooved bill than the Shiny Cowbird.

The Shiny Cowbird, not beloved by many birders, is a brood parasite, like the European Cuckoo, laying its eggs in the nests of other birds, and in some cases endangering host species survival.More photos...
