Red-and-green macaw
The green-winged macaw (''Ara chloropterus''), also known as the red-and-green macaw,〔 is a large mostly-red macaw of the ''Ara'' genus.
This is the largest of the ''Ara'' genus, widespread in the forests and woodlands of northern and central South America. However, in common with other macaws, in recent years there has been a marked decline in its numbers due to habitat loss and illegal capture for the parrot trade.
==Description==
The green-winged macaw can be readily identified from the scarlet macaw. While the breast of both birds are bright red, the upper-wing covert feathers of the green-winged macaw is mostly green but can occasionally sport a few yellow feathers above the band of green (as opposed to mostly yellow, or a strong mix of yellow and green in the scarlet macaw). In addition, the green-winged macaw has characteristic red lines around the eyes formed by rows of tiny feathers on the otherwise bare white skin patch; this is one of the biggest differences from a scarlet macaw to the casual viewer. Iridescent teal feathers are surrounded by red on the tail. If seen together, the green-winged macaw is clearly larger than the scarlet macaw as well.
In terms of length, this species is second only in size to the hyacinth macaw, the largest of the macaws. The red-and-green macaw attains a total body length of in adults.〔Cameron, M. (2012). ''Parrots: the animal answer guide. JHU Press''.〕 Twelve adults were found to average .〔''CRC Handbook of Avian Body Masses, 2nd Edition'' by John B. Dunning Jr. (Editor). CRC Press (2008), ISBN 978-1-4200-6444-5.〕 A weight range of between has been reported.〔 While its weight range is broadly similar to that of the hyacinth, the average weight of the red-and-green macaw is slightly surpassed by both the hyacinth and great green macaws, and amongst all living parrots additionally by the kakapo.〔〔
