Their appearance is generally green with the most notable features being a bright red forehead and crown, dark blue streaks behind the eyes, and light green cheeks.
Their natural range is across the lowlands of northeastern Mexico. Feral birds have bred in urban communities of southern California, southern Florida, and the island of Oahu in Hawaii. Birds in the Rio Grande Valley of Texas may be either feral, descendants of natural vagrants from Mexico, or both.
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.
This parrot is often kept as a pet and can be very affectionate and playful when given the attention they need from their owners. Although some are excellent talkers and copy voices, they are best at mimicking sounds.
