Actually a few years ago and not a sit - visiting raptor rehabber near Prague. This is Omar the vulture - but not sure what kind. Also owls, eagles, hawks… I had a piece of raw chicken in my hand (not holding too tightly) and the bird flew to me to grab it. You do need both arms to land this bird. It is actually an airbnb experience -https://www.airbnb.com/experiences/713637
