[Tweeters] Counting birds by the full moon

[Steve Hampton]

The moon-migration research was described in detail in Rebecca Heisman's
book, Flight Paths <https://rebeccaheisman.com/flight-paths/>, and in her
recent presentation to the Washington Ornith Society. Her talk is online.
The moon topic starts around minute 8.
