I'd have to agree w/ Snowdog. I'm not sure what I'd do unless I was in that situation. But my initial thoughts are that I love the chess game that's played between myself and the gobbler. Calling - changing calls - hanging up - the whole deal....that's what makes the hunt for myself.

I know the bird doesn't "belong" to anybody therefore you have done no wrong. But knowing that this other guy was calling and the bird was moving towards him....I may have passed on that bird to enjoy another hunt.
