Complexity of a male bird’s song can help attract the most compatible mate, new research suggests. Researchers investigated whether song repertoire and complexity advertises the singer’s genetic dissimilarity to others in the population — something that could help a couple raise the most viable young.

Researchers analyzed spectograms of Hermit Thrush songs, which revealed significant differences in song structures of three major populations—Northern, Western Mountain and Western Lowland thrushes.

Zebra finches’ courtship serenade preferences shaped by developmental exposure
