The songs and genes of Marsh Wrens tell of two species in North America

Since the late 1980s, we’ve known of an abrupt transition in Marsh Wren singing styles across the Great Plains of the United States.

To the east, songs are semi-musical and far more homogeneous, and males learn only about 50 different songs.
