how do i take care of my hurt pigeon?

[peachykeen]

i found a pigeon flopping in the street on my way home from work tonight. a cat had been 'playing' with it. i stayed with him a while and then put my coat over him, picked him up and carried him home.

he (or she, i guess, i have no idea) can't fly, but he can move his wings. his poop looks like normal bird poop, not really runny or anything. his eyes are open and he seems very alert. the ends of his wings are tattered. under one is fine but i haven't gotten a look under the other one. he's a bit sticky in places (underneath mostly but i haven't taken a close look yet) and one of his feet is a little messed up.

right now he has some warm water with a bit of sugar in it. i dipped his beak in but he didn't even open it. there are also some bread crumbs. he's in a box lined with paper and a cloth. and he's in the dark.....

what should i do? should i be feeding him? what should i feed him? should he be in the dark? should he have a water bottle or something with him?

please give me some advice as i have no idea what i'm doing with this poor little guy!
thanks!!
