Ravens

I'm wanting to get a raven, crow or any corvid hybrid for my kids this year. I Had pet crows growing up.. As far as I know it's illegal to keep native Ravens and crows as pets in most states if not all U.S. Does anyone know if there are any states that allow wild take of ravens or crows? I'm interested in buying one, but the going rate for an african raven is 3,000 or more, I'm not gong to pay that much! Another option may be some that are held by rehabbers? if anyone has any info on how I can get my hands on one I'd appreciate it. Thanks,
Jonathan
