When I first started trapping it didn't take long to learn that Gray foxes stay in very small areas compared to coyotes. About 5 days was the time limit that I could catch Gray foxes before I needed to move those traps. With coyotes I could go up to a month and still be catching some coyotes.I like how they are so quick to respond to the call. If you set up close to where they are they are coming in----and fast. If I don't have something come in within five minutes I start thinking they just aren't around.
Really cool at night when I am hunting with a light to see those eyes bouncing along as they come in.
