Yellow-green Finch Pselliophorus luteoviridis

Endemic to the highlands of western Panama, there is apparently no geographical overlap between Yellow-green Finch and its sole congener, the Yellow-thighed Finch (Pselliophorus tibialis), with which some past authors have considered the Yellow-green Finch to be conspecific. Both species possess yellow thighs, but Yellow-green Finch is characterized by its bright olive-green body plumage, contrasting with the blackish head, wings, and tail. The bend of the wing also is yellow. Very few data appear to have been published concerning its life history, although most facets of the behavior of this species might be expected to be similar to those of the Yellow-thighed Finch. The IUCN classifies Yellow-green Finch as Vulnerable, as much of its core habitat is threatened with deforestation and it is known from only few locations. In Spanish it is known as saltón verdiamarillo.
