Lost blue parakeet Pico with blue leg band 42

I lost my blue parakeet Pico yesterday around 3:15pm. We were outside the Fort Dodge Public Library on Central Ave near the main entrance when a gust kicked the door and Pico slipped from his cage on the balcony. Pico is about 6 inches from beak to tail, cobalt blue with a pale yellow chest, and there’s a tiny white patch on his left wing. He also wears a blue leg band with the number 42. This bird means a lot to me—Pico was a gift from my grandmother, and I’m really worried about him being out in the town. If anyone spots him nearby, please let me know or bring him back to the library steps; I’d be forever grateful.
