Do geese glow in the dark?

Only against the moon or when passing below clouds that are backlit by the moon.

You can also spot them if you are in an urban area where there are parking lot lights on.

If you are interested in observing night flight, listen for a member of the flock to be honking as they pass by. Seems most of the geese I see at night have a member of their flock emitting a honking signal.
