One Big Ass Bird

Visited the Bald Eagle days for a bit tonight. it was very noisy in there, but I believe she called this bird a Hackly. They come from South America she was with the wild bird sanctuary, the only birds they don't release after rehab are those who for one reason or another wouldn't survive. I would say this bird is twice the size if not more then a Bald Eagle. I have been corrected thank you Wingnut, this is a Harpy Eagle!
