IUCN Conservation Status: Least Concern
A small, secretive bird of freshwater marshes, the Sora is the most common and widely distributed rail in North America. Its distinctive descending whinny call can be easily heard from the depths of the cattails, but actually seeing the little marsh-walker is much more difficult.
Call a long, high descending whinny. Also a two-noted "sor-AH" call, with second note higher.
