Red-cowled Cardinal ( Paroaria dominicana )

18cm Unlike the Red-crested Cardinal ( Paroaria coronata ) the Red-cowled Cardinal does not have a crest and the absence of black patches on the head and throat distinguishes this from the other Brazilian cardinals.

Its beaty often costs its freedom as thousands of these birds are captured in the wild to be kept as cage birds. There is large illegal traffic of these birds throughout Brazil and even to other countries. Several specimens, and even established breeding populations have been reported considerably far from its original distrib...

Suiriri Flycatcher ( Suiriri suiriri )

There is still some debate on this bird’s taxonomic status. The Brazilian Official Bird List considers two species, the Suiriri Flycatcher, with two subspecies, the Chaco Suiriri, and the Campo one, which differs from the previous for having a yellowish rump, instead of grayish, and there is the recently described Chapada Suiriri ( Suiriri islerorum ), similar to the Campo one (possibly hybridizing with it) but with a smaller beak and white in the tip of the tail. Very little is known about this species. It is mostly solitary and uses the same hunting techniques of most other flycatchers, that consist basically of catching flying insects few meters away from its perching site and returni...
