Yes definitely take it to Wildlife Rescue they are awesome and will help the Mockingbird I have taken quite a bit of injured wildlife to them
I truly don't know call them and ask
I would recommend you surrendering the mockingbird to them. Their vet staff is amazing and will be able to provide the best care and treatment for the bird. I believe though that you are allowed to pick the bird back up and take it back where you found it once its cured and ready to be released.
I don't think they'll make you surrender it but it takes alot more than you think to successfully raise a wild baby bird.
