If you do find dead birds like this (if they're fresh and not freeze-dried or damaged) you can store them in your freezer in plastic bag so they can be donated to the Cornell Museum of Vertebrates the Cornell Lab of Ornithology (when they eventually are open for the public again). I'm not sure if there's any system in place currently for accepting specimens. If you decide to store one, you should put a little slip of paper in the bag that says the date, location, and how the bird died (or how you found it). You don't have to worry about identifying the bird if you don't know what it is. And freezer bags are always better, since they're made for keeping things safe in a freezer.
