Lost green parakeet named Rico with bright yellow face and notch in left wing near Westside Park, Gainesville.

I lost my green parakeet named Rico while walking near Westside Park in Gainesville yesterday evening. He usually stays close but took off after a loud noise. He has a bright yellow face and a little notch in his left wing. I'm really worried about him, so if you see him or have any information, please reach out!
