Yellow-throated Euphonia Euphonia hirundinacea Scientific name definitions

Yellow-throated Euphonia is found from southern Tamaulipas in eastern Mexico to western Panama, at elevations from sea level up to about 1800 m. Males are blue black above and yellow on the underparts and on the forecrown; unlike Scrub Euphonia (Euphonia affinis), with which it often occurs, the yellow of its underparts extends forward to the base of the bill. Females are dull green above and pale gray below with yellow along the flanks. Like Scrub Euphonia, this species is found in a variety of habitats ranging from intact forest to isolated trees in pastures. As is typical of the genus, Yellow-throated Euphonia builds a small spherical nest with a side entrance; the nest is placed in a recess in a bank, such as along a road, or may be nestled in an epiphyte or clump of moss high above the ground. Nests of Yellow-throated Euphonia frequently contain up to five eggs, a very large clutch size for a Neotropical passerine. Yellow-throated Euphonias are highly frugivorous, feeding primarily on mistletoe berries, and even the nestlings are provisioned with regurgitated fruit.
