I am having the same problem up here too, the birds I am seeing are holding real tight, then they tend to flush head on. But there is still alot of cover let that is stil green. Up here the ruffed grouse ussually want to flush away, or holdtight and go up behind you, they the I have gotten are young, but taking the oldest out on youth season this weekend hopefully I can get a better feel for the birds with him scuffing his feet , he's only 10 but time will show him the experince he'll need to wlak, but right now he is a good bird flusher.
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.
