The Grayish Saltator belongs to the same family as the Black-headed Saltator, which at my parent’s home in Río Frío is much more common. As it name implies, its upperparts are gray, but the underparts are brownish, particularly close to the vent. The throat has a central white stripe, bordered by two black strips. It also shows a white supercilliary which ends right after the eye. The beak is strong as other Saltators. They sometimes come to fruit feeders, but are more wary that most other birds.
The Nicaraguan Seed-Finch is one of Costa Rica’s biggest finches species, only surpassed by the Wedge-tailed Grass-Finch, which is even rarer and has a longer tail. It looks similar to the Thick-billed Seed-Finch, with the male being uniformly black and the female uniformly brown, albeit with a bigger size. Their bills are undoubtely specialized for breaking down seeds and the male’s bill is particularly conspicuous, given its pink coloration. In Costa Rica, it can be found in lowland areas of the northern area, near the border with Nicaragua, and in a thin strip along the eastern coast of the Caribbean.
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.
This is a very small and nervous bird. Taking a close up picture of this bird proved to be difficult, even during sunny days with great light available. The male in low light it looks black, but in sunlight it glows in a metallic blue color. The female is rather drab, sporting a brown look. The male perches in fence wire and posts, then suddenly starts jumping while making its call, doing acrobatic maneuvers in mid air, all to attract nearby females.
