Aracari


An aracari or araçari
is any of the medium-sized toucans that, together with the saffron toucanet, make up the genus Pteroglossus.
They are brightly plumaged and have enormous, contrastingly patterned bills. These birds are residents in forests and woodlands in the Neotropics.

Taxonomy and systematics

One species, the distinctive saffron toucanet, was formerly placed in the monotypic genus Baillonius, but Kimura et al. showed that it belongs in the genus Pteroglossus.

Extant species

Fourteen species are considered to belong to the genus Pteroglossus:

Former species

Some authorities, either presently or formerly, recognize additional species or subspecies as species belonging to the genus Pteroglossus including:
Some species of aracaris are unusual for toucans in that they roost socially throughout the year, up to six adults and fledged young sleeping in the same hole with tails folded over their backs.

Breeding

They are arboreal and nest in tree holes laying 2-4 white eggs.

Food and feeding

All the species are basically fruit-eating, but will take insects and other small prey.

Threats

The ischnoceran louse Austrophilopterus flavirostris is suspected to parasitize most if not all species of aracaris, with the possible exception of the green aracari.
