The Chopi Blackbird is a completely black bird but can be distinguished from Shiny Cowbirds by its grooved lower mandible. It also often seems to have spiky head feathers.

We saw Chopi Blackbirds in the Pantanal, Chapada das Guimaraes and upstate Rio de Janeiro, in Brazil.

I saw a flock of Red-breasted Blackbirds in a field in southern Para, Brazil. The male, pictured above, has a red breast. Females are borwn and yellow, streaked.

These were the only ones we saw in Brazil, since we didn’t visit this kind of habitat much in the north, but it looked like it might be quite a common bird around farms.

Red-breasted Blackbirds are the northern equivalent of the White-browed Blackbird, which occurs further south.
