Steve and I had a good laugh and then together named him Jonathon Livingston Pigeon.
He came to me with a bum leg, and back wound, and an inability to fly. He's been eating and drinking well, and yesterday flew a short low distance (while Marian and I raced to tackle the stalking cat which motivated his efforts) and had slightly more mobility in his bum leg. (No fractures that I can find.)
And best of all? Today he pecked both me and Marian for the first time, so it seems his uncharacteristic docility and trust of humans may be coming to an end--, something I welcome wholeheartedly.
(He deposited that poo just for you, as I moved him around for a better picture angle. Enjoy.)
