Velvet-fronted Euphonia

The velvet-fronted euphonia (Euphonia concinna) is a species of bird in the family Fringillidae, the finches and euphonias. It is endemic to Colombia. == Taxonomy and systematics == The velvet-fronted euphonia was originally described in 1855 with its current binomial Euphonia concinna. The genus Euphonia was long placed in the family Thraupidae, the "true" tanagers. Multiple studies in the late twentieth and early twenty-first centuries resulted in its being reassigned to its present place in the family Fringillidae. The velvet-fronted euphonia is monotypic. However, some early twentieth century authors treated it and what are now the orange-crowned euphonia (E. saturata) and Finsch's euphonia (E. finschi) as conspecific. == Description == The velvet-fronted euphonia is 9 to 10 cm (3.5 to 3.9 in) long and weighs 9 to 12 g (0.32 to 0.42 oz). The species is sexually dimorphic. Adult males have a small yellow forecrown; the color extends just to the eye and is separated from the bill by a thin black line. The rest of their head and their upperparts are blue-black with a purplish gloss. Their tail is also blue-black. Their flight feathers are black with usually a small white spot at the base of the outer primaries.…
