A freind of mine did one of the controled hunts, DNR guys there said his deer was old , very old. After they did a autopsie and took its lower jaw and organs they let him have it, 5 hours later !!! They did not do this to everyone that got a deer, I guess they were just interested in his because as I said it was very old.
When calling coyotes, more often than not they will circle on a target they are
coming into and approach from the downwind side. Presumably they do this in
order to align what they smell, with what they are hearing.
This means that you should always have your downwind side camouflaged and have
an open shooting lane. If the area is heavily covered the coyote could come in
take a look and be gone, with you none the wiser.
