The Golden-collared Macaw nest in a hole in a tree.

The Golden-collared Macaw was described by American ornithologist John Cassin in 1853.

The undertail and underwing are greenish-yellow similar to that of several other small macaws (e.g. Red-bellied and Golden-collared Macaw).

The Golden-collared Macaw or Yellow-collared Macaw (Primolius auricollis) is a small mostly green Central South American parrot, a member of a large group of Neotropical parrots known as macaws.
