Found green parrot with orange beak near Grassmarket

I found a small green parrot this afternoon around 2:15pm outside a cafe on Victoria Street, near the Grassmarket in Edinburgh. It's about the size of a large robin, with a bright orange beak and a few blue-tinted tips on the tail feathers. It wears a blue leg band with the code ED-23 and has a slightly ruffled look, like it's been out in the drizzle. It perched on my sleeve for a minute before hopping onto a nearby railing and looking around. I'm hoping to reunite it with its owner—if you recognize this bird, message me here with the leg band code and where you last saw it; we can arrange a safe meet-up in Edinburgh to return it.
