|Suiriri Flycatcher (Suiriri suiriri)
(aka Chaco/Campo Suiriri - Suiriri affinis)
|Chapada dos Guimarães, Mato Grosso, Brazil
There is some debate as to whether this is one species or two. It is currently treated as one by the CBRO and most other authorities. However, this bird which, if split, would be called the Campo Suiriri (Suiriri affinis) differs from the Chaco Suiriri (Suiriri suiriri) in having a pale buffy-yellow rump, belly and tip of the tail. It also sits more horizontally and it flicks its tail when perched. Furthermore, it has a different voice.
|However in a recent paper, it is suggested that S. affinis should be treated as a sub-species of S. suiriri. The paper also describes a second species, Chapada Flycatcher Suiriri islerorum, see:
