Trinidad Euphonia

The Trinidad euphonia (Euphonia trinitatis) is a species of bird in the family Fringillidae. It is common in northern Colombia and northern Venezuela and uncommon to rare on the Caribbean island of Trinidad. Like all euphonias, it is small, stocky, and short-tailed; unlike some, it is sexually dimorphic. The male is glossy blue-black on the head, back, throat, and upper breast, with a bright yellow forehead and crown, and bright yellow underparts. The female is olive-green above and yellow-olive below, with a grayer patch running down the center of her breast and abdomen, and bright yellow undertail coverts. Its calls are high-pitched, plaintive whistles: the two most common are a single-pitched, double-noted "pee pee" or "tee dee", or a rising, double-noted "puwee", "cooleee" or "duu dee". Wikipedia →
