those big black  birds,who wait untill something is dead untill something is dead.do you think they can see the spirit leave the body.ive often thought of this.your thoughts on this please.george

Vultures?  My experience with vultures (we mostly call them buzzards around here) is that they don't have a lot on their minds but eating, but I suppose they might see such a thing.  If they do, I bet they don't even notice it as anything out of the ordinary.

Also, they tend to go for things that have been dead a while, if that makes a difference.

I had one fly in front of the truck once, a few years back.  I scared the poo out of it.  Vulture poo is not a pleasant thing to have to clean off a windsheild.  :)
