Purple-throated Euphonia

Euphonia chlorotica

Tiny11 gForest

The purple-throated euphonia is 9 to 10 cm (3.5 to 3.9 in) long and weighs about 8 to 14 g (0.28 to 0.49 oz). The species is sexually dimorphic. Adult males of the nominate subspecies E. c. chlorotica have a bright yellow forehead and forecrown; the color extends to the rear of the eye. The rest of their head and their upperparts are glossy blue-black that in good light has a purplish tinge. The upper side of their tail is blackish and the underside duller with white on the inner webs of the outer two or three pairs of feathers. Voice: The purple-throated euphonia's song is "a jumbled series of squeaks, harsh notes and whistles" that is infrequently heard. A typical call is "a high, clear, whistled teee, deee" that is often lengthened to three or four notes as "teee, deee, deee"; occasionally it makes only a single "teee". The notes are on a single pitch.
