Maybe the available prey was getting low, so they relocated where there was more plentiful food! I don't even want to think about what the foxes are eating around here...other than what I put out, of course! The doe prefers what I put out for birds to the deer feed, although she will eat some of it. The raccoon raids the bird feeders at night...and lately during the day also. But it'll eat most anything also...filched catfood being its favorite food.
