We had a friend who found a hummingbird stuck beak first into the screen of his sunroom. He pushed the tip of the beak until it was all the way out and it just sat there. He carried it to his hummingbird feeder where it glugged down for a good minute as it sat in his hand then it flew off. Very cool! 
My DH tried to help a beaver across the road once. The beaver did NOT appreciate the help! LOL
