On 18 November 2010, another group was heard and tape-recorded from dense scrubs on the border of a semideciduous forest fragment near the district of Meloso (19o03’00”S; 43o21’24”W, 720 m). A local farmer reported that this species used to be much more common in the region seve- ral years ago, but it has become very rare nowadays, probably due to hunting and deforestation.
