Trinidad Euphonia

The Trinidad euphonia is a small, stout, short-tailed passerine, measuring 9.7–11 cm (3.8–4.3 in) in length and weighing 8.8–14 g (0.31–0.49 oz). It is sexually dimorphic in plumage. The male is glossy blue-black on the head, back, chin, and throat, with a bright yellow forehead and crown, and bright yellow underparts. The basal half of his rectrices are white, as are his underwing coverts; the latter results in a white stripe on his underwing when he flies. He also has white on the inner webs of the outer two to three tail feathers; this appears as two large white ovals on the undertail. Voice: A "notably vocal" species, the Trinidad euphonia has whistled calls that are high-pitched, plaintive, and hard to locate. The male typically sits at or near the top of a tree to call, often sitting on a semi-exposed or bare branch. One regular call, variously transcribed as "pee", "tee", or "dee", is typically doubled, though sometimes it is repeated 3–5 times, and exceptionally up to 20.
