found exotic bird, need help with basic knowledge

Question
Hi, I just recently got a mccaw. My mother-in-law caught him running around her r.v. park. she had seen him running around for about a week. she has looked and called and asked around town to see if somebody would claim this bird.  We have had no such luck.  So my question is what do they eat, and just a little bit of information about them.  I have absolutely no knowledge about birds let alone this beautiful parrot.  So just a little information from you would be fantastic if maybe you could tell me some.

Answer
Are you sure it's a macaw?
 It wasn't flying?

What kind of macaw?

Take a look at my page and let me know if you see what looks like your bird - there's also lots of info about keeping them properly.  

You can email me directly from there, or here. Either way, I'll do everything I can to help you all the way!
