Chestnut-fronted Macaw

A medium-sized macaw of Central and South American tropical forests from southern Mexico to Bolivia and Brazil, chestnut-fronted macaws have predominantly green plumage with a chestnut forehead, red shoulder patches, and blue flight feathers. The smallest of the true macaws, they inhabit forest edges, savannas, and secondary woodland and often raid crops, making them locally unpopular with farmers. They are popular aviary birds, but wild populations face pressure from trapping and deforestation.
