Tawny-capped Euphonia

The tawny-capped euphonia (Euphonia anneae) is a species of bird in the family Fringillidae, the finches and euphonias.

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 tawny-capped euphonia and the orange-bellied euphonia (E. xanthogaster) form a superspecies. The tawny-capped euphonia has two subspecies, the nominate E. a. anneae (Cassin, 1865) and E. a. rufiventrix (Salvin, 1866). == Description == The tawny-cappeded euphonia is 10 to 11 cm (3.9 to 4.3 in) long and weighs about 15 g (0.53 oz). It is a small euphonia with a thick bill. The species is sexually dimorphic. Adult males of the nominate subspecies have a rich rufous-chestnut crown.
