[2] P. crassus has a large range extending across northern-central western Africa, from eastern Cameroon and southwestern Chad across the Central African Republic and extreme northern DRC into the southwestern edge of Sudan.

[3] Distribution and population of this parrot are currently unknown, and the conservation status of this bird is of least concern because it is not known to be globally threatened and does not approach a small enough range for a higher conservation status.

[4] Most of the range of the Niam-Niam parrot is located in the Central African Republic and thus the species enjoys both plateau savannah and highly diverse forests.

Poicephalus parrots tend to be arboreal, resting and nesting in trees located within their territory.

Seeds, fruit, leaves of a variety of trees and shrubs, nectar, insects, maize, and millet have all been observed to be part of their diet.
