Found green parakeet with yellow face in Ithaca

Found a small green parakeet this afternoon around 4:15pm outside the Ithaca Commons, by the fountain on State Street. It's about the size of a typical parakeet, with an olive-green body, a bright yellow face, and tiny blue cheek patches. There's a blue leg band on one leg with the number 21, and the bird seems healthy and curious but clearly someone’s pet. I know this is someone's bird, and I hope to reunite it with its owner soon.
