I can say that for gray fox, my previous post holds true, but reds are more cautious and shy. Instead of running up and getting within 10 or 15 yards like grays do, a red will often get within 100+ yards and then hang up on you. If you see eyes coming in that suddenly stop and hesitate, it' s probably a red.

Bobcats are even more shy than the red fox, so you might consider calling at an even lower volume after the first 5 minutes or so.

For crows, you' ll want to keep it cranking so that passing flocks will have a better chance of coming in. They' re easier to see and hear when they approach anyway.

From what I' ve read about coyotes, you should set up at least 1/2 mile to 1 mile apart for each calling sequence and call for approximately 30 minutes before moving on to your next stand.

As a side note, I have a hunting buddy who has had great success using styrofoam and a wine glass to call fox. He said that when you rub the styrofoam on the outside of the glass, the loud, high-pitched sound drives them crazy! Has anybody else heard of this???
