Many of these birds were bred in the early 2010s but have since become much rarer. Their appearance can range from a harlequin-like bird with a reddish chest and more green coloration to a miliquin-like bird that is mostly dark green with an orange abdomen. They typically have small red crowns. Camilla hybrids are 50% green-winged macaw, 25% blue and gold macaw, and 25% military macaw.
