Skorpio,thank's for caring
I have a flock of about 30 Pigeons coming to my feeders and I love them.
If I find a wounded bird,I take it to our Humane Society(Oakville)they have an outdoor large cage for birds.
Often times though,I am sure they euthanize if the wound is too severe.
They are fragile,but it is possible he can survive,he could be in shock right now.
You can get some Pigeon-feed,I saw it at WalMart the other day,although "my"Pigeons eat good birdseeds and corn.
If you cannot find any place to take him,could you keep him warm and fed in a carrier.
It's possible he was attacked by a Hawk and something scared the Hawk away,I have Hawks going after the Pigeons here every day in the winter.
for the Birdie
