Bindenarassari

Bestimmung

The many-banded aracari is 43 to 46 cm (17 to 18 in) long including the 11 to 12.5 cm (4.3 to 4.9 in) bill. It weighs 215 to 302 g (7.6 to 11 oz). Males' and females' bills are alike in color; the female's is shorter. The bill has an orange-yellow line at its base. Its maxilla is orange-yellow with a wide black stripe on the culmen and a black base. Its mandible is black. Adult males have a mostly black head, throat, and neck but for bare blue-green to green skin around the eye and a chestnut patch behind it. Their back is dark green and their rump is red. Their underparts are yellow with two bands, the upper one black and the lower one black and red. Their thighs are a mix of chestnut, green, and yellow. Adult females have little or no chestnut behind the eye and their black breast band is usually wider than the male's. Immatures are overall duller than adults, especially the yellow. Their bill is gray, brown, horn, and black without the yellow basal line. Their thighs are green.

Verbreitung und Lebensraum

Resident species

Verhalten

The many-banded aracari is believed to be a year-round resident throughout its range.<p>The many-banded aracari forages singly, in pairs, or in small groups. It is primarily frugivorous and also includes insects, small birds and bird eggs, and lizards in its diet. It plays a role in seed dispersal of fruits with a dispersion range of hundreds of meters. It is likely to regurgitate seeds as opposed to excreting them.<p>The many-banded aracari's breeding season is thought to be between November and March in Colombia and Ecuador and from March to October in the rest of its range. Nothing else is known about its breeding biology.<p>The many-banded aracari's calls are variously described as "seeent", "seeet", "see-yeet", "kyseek", and "kyeek".
