it was found dead outside a warehouse I'm seconded to this week. I think it may have flown into a concrete wall.

I emailed our local wildlife rescue; I initially didn't want to throw it out in the garbage as my coworker told me to do, and when I realized it's a bird I'd never seen before, I wondered if it should be reported to a rare bird sighting place.

Anyways, I emailed the pics and she wrote back saying it looked to be a Yellow Rail (you're pretty close, azfiddle!), a common visitor in our parts during fall migration. I wouldn't say the warehouse is right by a marsh, though it's not too far from estuaries and a couple of bogs.

And zen, to answer the question of where it's been all day, well... in the fridge. And don't worry, Roxy, I packed him/her up with gloves (2 pairs, actually!) in a plastic bag inside a paper bag inside a cardboard box. Looks like I'll be taking him/her somewhere tomorrow to bury. Can't dignify throwing him out in the garbage
