Buffon Macaw
Ara ambigua
Larger cousins of the Military Macaw, these unusual beauties are distinguished by their overall more massive body and beak, a yellowish tone to the green feathers, plus orange rather than burgundy tail feathers. They also have a rather more placid and gentle nature.
Rare in the wild - and indeed in captivity too - these birds should only be considered as pets if kept in pairs and then given the opportunity to breed when mature.
