Bronze-green Euphonia
Euphonia mesochrysa
The bronze-green euphonia is 9 to 10 cm (3.5 to 3.9 in) long and weighs 12 to 15 g (0.42 to 0.53 oz). It is a rather drab euphonia with a thick stubby bill. The species is sexually dimorphic. Adult males of the nominate subspecies have a bright yellow forehead with a thin dark olive band below it. Their mid-crown is olive, their rear crown grayish, and their nape and the rest of their face olive. Their upperparts are olive with a strong gray-blue gloss. Their upperwing coverts are olive-green and their primary coverts blackish. Voice: One description of the bronze-green euphonia's song is "2 clear notes followed by a musical trill, tee-teeu-trrrrrt". Another is "usually a whistled note followed by one or more ringing rattles, for example peew brrrrrrr brr brr". Its call is "a distinctive, gravelly treeuh, treeuh".

Velvet-fronted Euphonia
Euphonia concinna
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".
