baby bird

Hi, I am new to this website, and the reason I have signed in, is that my tom cat Manson has brought a baby bird to my house last nite. The birdie is still alive and I have managed to keep the baby alive, at the moment I only fed him with sugar water. I am thinking getting a dog canned food and start feeding him with proper food, but I would really appreciate if someone could come bk to me and give me more guidance, or a place where people look after animals like this, where I could make sure he is safe. I will look after him no matter what (if he will pull through) , but if there is a place, I could perhaps bring him. thank you in advance

Regards Dagmara
