Tiny blue parakeet with orange cheeks, lost

I lost my tiny blue parakeet named Sunny yesterday around 3pm. He's about 6 inches from beak to tail, cobalt blue with orange cheeks, and a white ring around his right leg; one tail feather is a bit frayed. I last saw him fluttering toward the street near the library on Main Street in downtown Nacogdoches, Deep East Texas, and I called him, but he vanished into the trees by the storefronts. Sunny was a shelter rescue and means a lot to me—he's bright, curious, and really lightens my days. If anyone spots him, please text me here or call, and I'll grab him right away.
