Are you familiar with handfeeding defrosted peas to a pigeon? Get him hydrated first by dipping the tip of the beak (not over the nostrils) in a small bowl of water. Can you post a photo of the toes?
looks like hawk attackFound this bird at the carpark of a mall earlier, it's tail feathers seem to be going through a bad moult with being almost naked and all pin feathers. It wasn't very responsive when I touched it, but did struggle a little when I picked it up, although it has seem to mostly been sleeping once I put it in my cat's carrier with some shredded paper for warmth. It's legs seem to be curled up under it, and it was puffed up when I found it. No injuries from what I can tell, but it seemed to have trouble trying to stand. View attachment 105481
