Ivory-billed Aracari vs Lettered Aracari

Ivory-billed Aracari

Pteroglossus azara

Medium144 gForest

The ivory-billed aracari is 36 to 45 cm (14 to 18 in) long and weighs 120 to 160 g (4.2 to 5.6 oz). The two subspecies (and the brown-mandibled species) do not differ appreciably in length, weight, or plumage but only in bill color. Adult males have a black cap above a chestnut head and throat, maroon-red nape and upper back, green lower back, and red rump. They have a narrow black band under the throat, a wide red band on the upper breast, a wide black band on the lower breast, a yellow belly, and green thighs. Voice: What is thought to be the ivory-billed aracari's song is "a series of 2–6 wailing 'twaaa-a-a' or 'tweee-ee' or 'traaa-at' notes". Other vocalizations include "rattles, grunt-like contact notes, nasal 'nyek', purr-like notes, 'kyeek' alarm, pure rattles 'bddddt'".
