Emberizoides ypiranganus
The Lesser Grass-finch is one of our more common birds. It resides and breeds in the long grassy areas that we maintain for our Strange-tailed Tyrants and is also associated with water.
It has a grating, chattering call which is quite different from the other Emberizoides species that we occasionally see.
It measures around 16cm, has a plumbaceous face with yellow mandible and black culmen. The upperparts are olive with heavy black streaks and greenish coverts. Underparts are pale whitish. The tail is long and spiny.
