I love watching birds of prey. I remember watching a nature program once and seeing a Harpy eagle with a 6-foot wingspan grab a 4-pound sloth from a tree. It came in sideways, literally angled more than 90 degress, to grab the sloth off the tree. This doesn't look like the same clip to me [youtube.com...] but it is still impressive. The program I was watching showed it in slow motion and it was just incredible.
