Sora rail release

Ryan, our Audubon staffer, let the Sora go out by the marsh where the students first discovered it.  The bird took off from his hand, proving to be a remarkably strong flier.  Ironically, it flew clear across the marsh and landed on the far bank of the pond; after a brief recovery, it ran up the bank into the woods!  In flight, it showed no distinct white trailing edge to the secondaries, a good field mark distinguishing it from Yellow Rail.  Soras are long-distance migrants, moving into southern North America and Central America for the winter.  But they are hardly ever seen in flight–so do they move at night, like most passerines?  If so, do they have distinctive flight calls like many passerines that would make it possible to track their movements?  I’ve never heard of rail flight calls…
