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 returning to it subsequently.
It is not common in urban areas, but may be frequent in farms and grasslands.
There is a paper describing a decline in this bird’s population after forest fires.
It is probably seasonal, but its migrating routes have not been investigated yet.
