I have a few ideas for ya. I like the spots I marked for one reason - edges. Without a topo it's hard to discern any other real key features other than what you have marked. So I like the edges of the thick stuff and the oaks food source with security cover near by seems like a good start. Same goes with the crab apples, thick stuff, and oaks - you have a few foods sources and security cover nearby. I also like the area between some of the thick stuff and the creek near the field in the Southwest portion of the map - seems like it could be a pretty decent area as well.
