Hi All,

If in doubt about a Sora call, I would encourage people to view the 
spectrograms for Sora in the Macauley Library. Spectrograms that show a sharply 
rising slope through most of the call are quite possibly Spring Peepers. Sora 
calls are longer and have a fairly long, relatively flat or gently rising slope 
in the first part of the call.
