Blue-green parrotlet found near Boston Public Library

I found a small blue-green parrotlet this afternoon around 3:15pm, perched on a railing outside the Boston Public Library’s McKim Building on Boylston Street near Copley Square. It’s about the size of a robin, mostly teal with a bright yellow belly and a tiny red beak. There’s a light blue leg band on its right leg engraved with '23-AL.' It seemed friendly and hopped onto my finger for a moment before scolding at me with a chirp. I’d really hate for someone to worry about it—losing a pet bird would be awful. If this is yours, I’m happy to help arrange a meetup near the library or at a nearby vet clinic to verify ownership.
