The Yellow-faced Grassquit is a seedeater found on grasslands. I have seen this species a few times at Fincas Bambuzal, Rio Frio where my parents live. The yellow face is diagnostic when trying to identify versus other seedeaters that may inhabit the same zone. They like to perch both on grass branches and in fence wires at the edge of trails and gravel roads; they will usually share space with Variable Seedeaters and Thick-billed Seed-Finches, although they are not confused easily with those species. Small juveniles take the risk to abandon the nest and call for their parents to feed them. It is very difficult to locate them in the tall grass.
