Green parakeet with blue tail, leg band

I found a small green parakeet this afternoon around 2:15pm near the Dia:Beacon courtyard on Beekman Street in Beacon, in the Hudson Valley. It's lime-green all over with a blue-tinted tail and a pale beak, and it wears a tiny metal leg band stamped 'NY-47'. The bird seemed calm and perched on the railing by the river before hopping onto a bench and letting me approach a bit. If you’ve lost a bird matching this description, send me a note here and we can set up a meetup to get it back to you.
