The red-and-green macaw (Ara chloropterus), also known as the green-winged macaw, is a large, mostly-red macaw of the genus Ara. This is the largest of the genus Ara, 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 distinguished 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 (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. Twelve adults were found to average . 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. Behavior The green-winged macaw generally mates for life. The female typically lays two or three eggs in a nest made in a hole in a tree. The female incubates the eggs for about 28 days, and the chicks fledge from the nest about 90 days after hatching. Population recovery Since 1999 a population has appeared on Trinidad. Although these might have escaped from captivity, it is also possible they have a wild origin. The historical range of this species is thought to have stretched southwards to include the Argentine provinces of Chaco, Corrientes, Formosa and Misiones. Hunting for meat, the pet trade and changes in land use are thought to have caused the species to be extirpated throughout its Argentine range by the 1960s. The species is listed as critically endangered in
