Callie found a hurt bird this morning. I picked her up and she seems unbroken (as much as I know about bird anatomy) She's flapping her wings but not going anywhere. I took her because I know she'd be dead within an hour thanks to the wild animals around here (many of them human who would think nothing of "playing" with a hurt bird)

I have her in a cat carrier and need to know what else to do for her. I think its a finch. Do I put a bowl of water in there? How shallow? Do they eat anything special or should I just go to the pet store? Of course its Sunday and I work at 11, making a trip to the pet store a bit difficult. I googled the question and didn't find any real help there.

She's very scared (I guess 7 curious cats and an obnoxious dog would do that) I'm calling it a her because I know male birds are more colorful than their female counterparts and she's very brown.
