Spot-crowned Euphonia

The spot-crowned euphonia (Euphonia imitans) is a species of bird in the family Fringillidae, the finches and euphonias. It is found in Costa Rica and Panama. == Taxonomy and systematics == The spot-crowned euphonia was originally described in 1936 with the binomial Tanagra imitans and the English name "tawny-bellied euphonia". The genus Tanagra (Tangara) is a member of the family Thraupidae, the "true" tanagers, where the species remained after being reassigned to genus Euphonia. Multiple studies in the late twentieth and early twenty-first centuries resulted in Euphonia being reassigned to its present place in the family Fringillidae. The spot-crowned euphonia is monotypic. == Description == The spot-crowned euphonia is about 10 cm (3.9 in) long and weighs about 14 g (0.49 oz). It is a small euphonia with a stubby bill. The species is sexually dimorphic. Adult males have a bright yellow forehead; the patch extends to the rear of the eye and is speckled with black. The rest of their crown and their face, nape, throat, chest, and upperparts are steely blue-black. Their upperwing coverts are a slightly glossy blue-black. Their flight feathers are dusky with a blue-black tinge and white bases on the inner webs of most feathers.…
