The songs of songbirds vary considerably within species as well as between closely related ones, with important consequences for mate choice, recognition of individuals and species, and diversification. Ecological selection (through direct and indirect influences of habitat and diet) and sexual selection (via male competition and female choice) appear to be primary drivers of song variation. A third factor, human-induced environmental change, also affects how birds sing, but its influence of light of ecological and sexual selection is unclear. In this talk, I will present recent research aimed at identifying patterns and assessing multiple drivers of song variation in field sparrows and house wrens.
