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.

The Shiny Cowbird is one of a few entirely black birds to be found in Brazil. The photo above is a presumed female - the adult male (below) is deep blue-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 has a grooved bill.

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.

The Crested Oropendola is the most common Oropendola, often seen at feeders in the Pantanal, Brazil; huge numbers seen returning to roost each evening in the Upper Napo region of eastern Ecuador (photo below); also seen as far west as Chiriqui, Panama (photo lowest) - it is currently expanding northwest into Honduras etc.

The Crested Oropendola has a pale yellow bill, bright blue irises, black body with long yellow undertail feathers, which extend past the 2 black central feathers, and chestnut vent and rump.

Charismatic birds which make wonderful noises and calls and a spectacular display (pic below).

Similar:

The Russet-backed Oropendola is the only Oropendola in the Ecuadorian Andes, which makes identification easier there. There are several subspecies, the eastern race has a dark bill, generally, whereas other morphs (south and west) have light bills.

All birds pictured on this page, except the lowest, were taken at the same lodge, San Isidro, on the eastern slope, but even at this one location there appears to be variability in bill colour and plumage (see below). You can get very good views of this bird at San Isidro Lodge.

There were also large numbers Russet-backed Oropendolas seen returning to roost each evening in the Upper Napo region of eastern Ecuador (photo below), I think mixed with Crested Oropendolas; I certainly identified some of each species in the flocks containing many hundreds of birds.

The eastern Russet-backed Oropendola, pictured here, is a dark bird with an olive head, variable bill colour, olive - brownish body and long yellow undertail feathers.

Range: Colombia to E Brazil & N Argentina
Similar: Scarlet-rumped Cacique, Subtropical Cacique

The Red-rumped Cacique is the most common form of Cacique in eastern Brazil. It is a large bird, quickly identified by its yellow bill, startling bright blue iris and red flash of colour on its rump, especially visible in flight. The rest of the bird is black. Sometimes the blue irises show as black, perhaps in juveniles or bright light, as can be seen in the photo of the juvenile begging for food.

Red-rumped Caciques nest in colonies of pendulous nests, which they add to year after year, so that some older ones are empty. This can work to confuse some predators such as snakes. They will also weave their nests with green garden twine and several nests were seen incorporating this man made material. In Itatiaia I often saw Red-rumped Caciques eating fruit, including that of cecropia. A good sized colony of Red-rumped Caciques by the lake at Regua too.

There are two separate populations of Red-rumped Cacique, one in southeast South America, including the southeast of Brazil, and one in northwest South America.

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.

The Orange-backed Troupial is a real stunner, quite regularly seen in the Pantanal and reasonably approachable. The bird above was the first one I saw, on day three of my Pantanal trip, as I was driving along the Transpantaneira. Too good to be true that this bird was feeding on a tree with similarly-coloured flowers! Of couse I stopped the car for a good fifteen minutes. I’d like to know what tree this is.

These are not Cowbirds, in that they are not brood parasitic or in the genus Molothrus. In fact they are parasitised by Shiny Cowbirds, whose juveniles look very similar.More photos...

The Giant Cowbird is a brood parasitic icterid, laying its eggs in the nests of oropendolas, caciques and some other birds such as jays. It is found from Central America to the northwestern half of South America and to a lesser extent the southern part of Brazil.

The Giant Cowbird is a large bird (40 cm) - it looks a bit similar to the Great-tailed Grackle in Panama, but the latter has a thinner bill. The adult male is larger and shiny blue-black, the female browner and smaller. Irises can be red or yellow, depending on regional differences, also in some regions males tend to have red irises and females yellow irises.

The females and juveniles are more difficult, mostly brown with the red replaced by ochre. Pictured below is one with yellow spots and red - perhaps a juvenile male?

The Chestnut-capped Blackbird is found in much of eastern South America and Colombia. In Brazil it lives in the south and east of the country.
