Bright green budgie with yellow face

I lost my bright green budgie yesterday around 3pm near the Lake Charles Civic Center on Lakeshore Drive. He’s tiny, about 5 inches from beak to tail, with a lime-green body, a yellow face, blue-tipped tail feathers, and a red leg band with the code A12. If you call his name 'Kiwi', he’ll usually chirp back, though he’s a bit shy around new people. This bird is a gift to my daughter and means the world to us—we’d really appreciate any sighting in the boardwalk/piers area and a quick reunion.
