First link is informing of a chat in Wyoming's Buffalo Bill Center of the West given by the biologist in charge of a reintroduction project for green winged macaws in Argentina [wish it was nearer to me, I would have loved to attend it!]. The second link is about the project itself. Apparently, green wings used to exist in Argentina but became extinct there and there is no an effort in reintroducing the species - cool, eh?
