Pigeon loses ability to fly. He adapts by becoming one of the dogs.

8. As a kid I had many pet pigeons

Heart warming story of a fallen pigeon finding a rewarding relationship with caring humans!

Farmers ask me to take the young birds, after they blocked off entrances of nesting adult pigeons into barns. I can attest that young pigeons will beg for food to the point of sticking their beaks right in your face demanding to be fed. As, two days before the pigeon eggs hatch, both the parents' crops become engorged with fluid-filled cells. The pigeon parents regurgitate this thick milky goop into the mouths of their squabs. This crop milk remains the squabs' only food for several days after hatching.

You can see Herman the pigeon is quite interested in young animals as any adult male pigeon would be. A virus or injury disrupted the birds very complex semi-circular canal and/or lumbosacral organ. Not to get to technical but a birds' balance, and body positioning, are very acute and rapid. Herman's odd head positioning and loss of flight seems to indicate this injury.
