Emerald parakeet with blue tail, lost near Friday Harbor

I lost my emerald-green parakeet yesterday around 6pm near the Friday Harbor Market on Spring Street. My parakeet is about 5 inches tall, with a bright blue tail patch and a tiny white scar on the left side of his beak. I can spot a red leg band marked 'A1' on his leg, and his cheerful chirp gives him away when I'm nearby. This bird means a lot to my family, especially my daughter, so I’d really appreciate getting him back.
