They are pretty smart, not Raptor smart, but they can be trained. There is a falconer that we see periodically that has a few vultures that are trained like the raptors (not to hunt, just to fly from place to place on command) for the show.Do they really have a brain inside such a tiny skull ? Or they just following instinct?
They will, rarely, but they can't grip with their feet and their beak isn't made to be able to kill easily (it's more of a grab a string of meat and pull type thing) so they aren't good at it and typically only kill sick or already weak or very young animals.If no carrion is available will they attack live creatures?
Also, the ones pictured above are Turkey Vultures, they have never been proven to kill, the ones that have been seen doing it are Black Vultures who look similar but they have a black head as an adult (Baby Turkey Vultures also have a black head)
