Are you in the UK? If so, is the pigeon a feral or a wood pigeon?
Feral pigeons can take quite a lot without suffering from shock, even severe blood loss at times. They quite often behave as if they are tame with humans because they have a lot of human contact.
Wood pigeons and collared doves are vulnerable to shock, but their reaction is to open their beaks and gasp, quite often they die if not left alone immediately when this starts.
Sometimes they lose their feathers in a cat attack (woodies and collared doves are designed to drop a ton of feathers if caught by anything) and if so will need antibiotics.
Examine his body carefully, looking for bruising or signs of a puncture wound. Also, look inside of its mouth to ensure that it is pink and healthy. Chesselike growths are a symptom of canker, blueness indicates lack of oxygen.
Don't try to syringe water into him unless you are absolutely certain that he is not drinking, but you could gently lower his beak into the water to see if that prompts him to drink. Also wait before you start force feeding him. Several feral pigeons that we rescued would sit stock still, ignoring food and water. When we put down peanuts and left them for a while we would return to find them exactly as we had left them, sitting like statues...but the peanuts had gone.
If the feathers of the tail have been completely "plucked" then they will grow back within 6 weeks.
