Green parakeet with blue cheeks, lost

I lost my green parakeet yesterday around 3pm near the downtown Ocala square, at the corner of S Magnolia Ave and E Fort King St. It's a small parakeet about 6 inches long with vivid green feathers, bright blue cheek patches, and a tiny white feather on its left wing. It wears a light blue plastic leg band marked CA-041. The bird is extremely friendly, and I've had him for about four years; he's basically part of the family. I'm really worried and would be endlessly grateful to get him back.
