Green parakeet with red tail, leg band

I lost my green parakeet yesterday around 3pm near the Inner Harbor promenade by the National Aquarium in Baltimore. It's a small-to-medium parakeet, mostly emerald green with a bright red tail and a tiny black beak. He has a light blue leg band with the number 42, and there’s a tiny white scratch on his right wing from a rough branch. This bird means a lot to me—I've had him for years and he’s been a cheerful constant through some tough days. If anyone spots him, please email [email protected]. I’d be forever grateful to get him back.
