Brown-breasted Bamboo Tyrant (Hemitriccus obsoletus)

About the Brown-breasted Bamboo Tyrant

The brown-breasted bamboo tyrant or brown-breasted pygmy-tyrant (Hemitriccus obsoletus) is a species of bird in the family Tyrannidae, the tyrant flycatchers. It is found in Argentina and Brazil. The brown-breasted bamboo tyrant has two subspecies, the nominate H. o. obsoletus (Miranda-Ribeiro, 1905) and H. o. zimmeri (Traylor, 1979). There is some evidence that zimmeri deserves full species status. Some early to mid-twentieth century authors considered the brown-breasted bamboo tyrant to be a subspecies of the drab-breasted bamboo tyrant (H. diops) but since at least 1966 most systems have recognized them as separate species. They and the flammulated bamboo tyrant (H. flammulatus) form a superspecies.
