Abstract
⺠We evaluated effects of urban noise on structure and salience of white-crowned sparrow song over a 36-year period. ⺠Birdsong increased in minimum frequency between 1969 and 2005 coincident with rising levels of traffic noise. ⺠Birds in urban environments gave stronger responses to current songs than to historical songs. ⺠Results support the hypothesis of habitat-dependent selection on cultural evolution of birdsong in urban environments.
