Hello all.

We recently bought a place in western michigan and we have some acreage on the river that I plan to hunt next year. We have a lot of deer in the area and we spend every night watching groups of 5-15. How can I tell which of these, if any, are bucks?

I've been told that you can tell a buck by the flatness of of the crown of their head, but I honestly have a hard time seeing much difference, especially when they are out at 50 yards. Does anyone have any links to pictures illustrating this difference?

Are there any other physical or behavioral characteristics which would give a clue?
