Harpy Vulture

The main thing that changed in the Harpy Eagle was their diet. In the present day, their diet is sloths, monkeys, opossums, etc but in the future, there will not be many trees for these animals so I think the Harpy Eagle will have to become a scavenger like vultures. The Harpy Eagle will not have any feathers on their head so they are more clean as well as easier to eat dead animals. As well as having a longer neck so it is easier to get into remains. The third thing is their feet vultures spend a long time on the ground eating as opposed to eagles in nests and trees. Because of that, they have long toes with blunt talons.
