Yellow-green budgie with blue leg band

I lost my yellow-green budgie yesterday around 3pm near Pullman Square in downtown Huntington. It's a small parakeet, about 5 inches from beak to tail, mostly yellow-green with a cobalt-blue tail and an orange beak. It wears a blue leg band with the code A12 and has a faint white crescent on its left wing. It’s been with me since last year and helps me get through rough days—truly a sentimental companion. The bird was out of its light-blue travel cage and may be stressed, so please keep an eye out near apartments along 7th Street and the riverfront path by Pullman Square.
