My dove is limping and not flying

Hello. I have a Eurasian Collard Dove that is limping, and appears weak as he does not fly as much anymore, not even up to his perch to eat his food. Can you help? Do we need to bring him in to see someone? Who would we bring him to?

Thank you so much, your help is MUCH appreciated, truly!
