The link goes to a poster of the putative extinct macaws of the Caribbean. Wikipedia says that there have been thirteen proposed Caribbean macaw species, but that there are doubts about this because only three have any extant physical remains.
The linked poster itself says that, due to prehistoric and historic human impacts, three-quarters of the original Psittaciformes of the Caribbean are extinct.
Extinct birds have long been of interest to me, even though learning about them makes me sad. When I found out about the Carolina parakeet, I sometimes tried to envision what the eastern United States would be like if they still lived. These Caribbean macaws are especially poignant to me because the Islands, in so many ways, remind me of the South American mainland, but with entire broad taxa missing – no howler monkeys, no toucans, etc. Those taxa may never have reached the Caribbean; but to think that macaws once flew over the Islands’ forests – what must that have been like?
When I used to walk that long road from the village to the beach, I would pass a house with painted wooden macaws on swinging perches decorating the veranda. I find them a poor substitute for the prospect of seeing the real thing flying free.
