Small finchlike bird, compact and short tailed. Generally yellow below and dark blue-back above with stout, short bill. To identify male euphonias, focus on the crown and throat: Orange-bellied has yellow cap and dark throat, as well as slightly orange-yellow belly. Females extremely difficult to separate from other euphonias but often seen in pairs or small groups with males. Frequents open forested habitats, edges, and gardens. Can form mixed feeding flocks with other species such as warblers and tanagers.
