red squirrel VS ruffed grouse

Went hunting for deer this evening. No deer but I did see something I have never seen before. A Red squirrel was munching on the two ears of corn I had brought for the deer when a ruffed grouse came into the clearing and started over to see if the corn was any good. The squirrel took exception to this and attacked. The grouse held it own for a few seconds but the squirrel did not let up and the grouse finally took off to find easier pickings. First round goes to the mammal. Vick's dogs have nothing on these two.
