well my friend called me this afternoon and said he had a baby bird that wouldn't leave....he guards at a near by pool, i coach the swimteam...he said he found it in the gudder of the pool



so he got it out dried it off and called me an hour ago. i just got back with him. he said the bird was there all day and would not leave. it was flapping his wings a bit...and i even saw him preen once. he is screaming for for food. his poops are clear and watery. i got him warm and he actually just fell asleep.
i attached photos....they're awful though SORRY!!!
I think he's a catbird/grockle/or cowbird but cant tell....i am gonna look online after i post this and look some more.
questions...
what am i gonna feed him? baby food? worms?
how warm should he be?
how often should he be fed?
oh! and i called the animal rehab place and they said they wont take him in...uhhh...and they would even tell me what to do or even give advice.

so any help please..:)
