The Red-crowned Amazon (Amazona viridigenalis), also known as the red-crowned parrot, green-cheeked amazon or Mexican red-headed parrot, is an endangered amazon parrot native to northeastern Mexico and possibly southern Texas.
They gather in large flocks being noisiest in the morning and evening. The characteristic screeching heard of these birds usually occurs when they travel in a large flock to a new feeding area. Their diet consists of seeds, fruits, flowers and nectar. Red-crowned amazons nest in tree cavities, like most other parrots.
A 1994 study estimated wild populations of between 2,000 and 4,300 mature individuals; the IUCN Red List considers it a globally endangered species with a decreasing population. The major threats to its population are illegal capture for the pet trade and destruction of natural habitat.
