White-bellied parrot

Appearance

The white-bellied parrot has an orange-yellow head and vent, a white belly, green wings and back, bluish primary feathers, a pinkish-horn beak, and pinkish legs and feet. Juveniles have brownish or black feathers on the head and nape, yellow feathers on the white belly, and greyish legs. Generally, the off-colored feathers will be lost and replaced by orange or white feathers respectively as the bird matures. Young birds also have dark brown irises, which will change to a rust or orange with age. The white breast feathers of wild caiques are often stained a chestnut brown color. This may be due to tannin staining, as result of their particular affinity for bathing by rubbing their bodies against wet leaves and other plant matter.

The head and nape plumage of the white-bellied parrot has been observed to fluoresce strongly under ultraviolet light.
