Plumbeous Euphonia

The plumbeous euphonia is about 9 cm (3.5 in) long and weighs about 9 g (0.32 oz). The species is sexually dimorphic. Adult males have a glossy dark gray head, upper breast, and upperparts. Their tail is dusky with a wash of olivaceous gray. Their upperwing coverts and flight feathers are dusky with wide olivaceous gray edges. Their underparts from their breast to the undertail coverts are bright yellow with some gray mottling on the sides and flanks. Adult females have an overall pattern similar to the male's though duller. Voice: The plumbeous euphonia's song is described as "a squeaky, jumbled o'fiddle-de-wEET!" that is sung quickly. Another description is a jumbled "WEET sweeta-swee-swee" that often includes call notes. The species' most common call is "a high, clear dee-dee or dee, dee-dee" whose notes are on one pitch.
