When I was a kid I had a pet crow nd he was amazingly intelligent. He learned like a small kid and was a sponge for new information. He would overlearn new tricks to do familiar tasks and he learned that since we were his "flock" hed usually just walk around rather than fly. He would ride on the back of our English Setter and the setter acted like it was no big deal. They became fast companions and Murphy would slep in the kennel in the doghouse.
He did have a mean bite though. He could punch a hole in a soda can with his beak. His"love pecks" could draw blood and I used a water pistol to reinforce his good behaivior. Murphy loved getting spritzed with the water pistol, and would do tricks like crazy for a squirt in the face.
