Velvet-fronted Euphonia

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. Their chin and throat are blue-black and the rest of their underparts are rich ochraceous to cinnamon-yellow. Voice: The male, and possibly the female, velvet-fronted euphonia sings "a slightly gravelly and varied series of phrases, e.g. p’wheeet-wheeet...pa’weet, whe’e’e’t, whe’e’e’t...pa’weet, p’bzrrrr, bzrrrr..." whose wheeet notes rise in pitch and are sometimes slightly burry. The bzrrrr notes are buzzy or rattling. Both sexes call with "a clear high dee-dee or tee dee-dee".
