That's very true, Rich. My personal experience is that raccoons spend most of the day in the trees, and won't bother to come down for a distress call. Night time, depending on the area, that's a way different story. They respond very directly, again, unless they are in trees. My impression is that Texas has a bunch of 'coons, we have some in the Sierras and in the local mountains, but there is wide gaps in the distribution, following water sources, I guess? However, I did see one right down in Coyote God's country; road kill just north of Elfrieda! Seemed a unlikely spot, and flat.
But, the advice about coon fight sounds and bird distress sounds are very good. Myself, if I call them, I tend to let them go, unharmed.
Good hunting. LB
