Glad he's ok. If you want I can see if I can find individual wildlife rehabbers near you or that you can call, who might be able to give you advice on his care and maybe getting permitted or certified yourself to be allowed ownership?
It's difficult to find someone willing to take you in as an apprentice falconeer and it's often passed down to family or friends, not people they don't know, but if you get involved in a forum and befriend others in the falconry hobby you may get lucky.
*** Oh and you may want to keep quiet about it to people you know or live near so word doesn't get out or you get reported by a neighbor or something while you are figuring what to do - because there is usually a very hefty fine and/or jail time for keeping any native species of bird, especially raptors. Here I believe it is a $5000 fine and up to a year in prison and the animal is confiscated.They can also tack on endangerment or animal abuse if it wasn't cared for properly and lord knows what else.
I'm not condoning keeping him or not keeping him, just warning to be careful and try to get legal one way or the other, whether it be bringing him to a rehabber or getting licensed.
