Abstract

Cinereous Warbling-Finch, Poospiza cinerea, is a poorly-known bird endemic to the Cerrado region and ‘Vulnerable’ to extinction. It has been suggested that this species may be nomadic because of its rarity and low density. We tested this suggestion throughout observations of two banded individuals in a ‘campos rupestres’ site at Serra do Cipó, state of Minas Gerais, Brazil. We also described some aspects of its natural history, including a preliminary estimation of the home range size. Estimated home ranges of the pair were 15.02 and 16.56 ha using two different methods. Home range comprises mainly rocky outcrops, with low-height vegetation, used for foraging on small arthropods. The pair showed year-round residency and long-term site fidelity for at least 3.5 years, thus contradicting the nomadism hypothesis.
