we have a family living in a dying oak tree down by our dam along a small stream. They are smart, they are tenacious, they must keep appointment calendars cause they know precisely when my neighbors sweet corn firld is ripe. AND, they will not allow beavers near the little raccoons. Little raccoons are amazingly precocious little shits. They will come up to you begging for food. If you feed the kit, the mother will come tearing out from wheteve she was sleeping to rip you a new one.
Besides beavers, fox and most dogs will give em lots of room.
