Differential geographic patterns in song components of male Albert’s lyrebirds

Geographic variation in bird song has received much attention in evolutionary studies, yet few consider components within songs that may be subject to different constraints and follow different evolutionary trajectories. Here we quantify patterns of geographic variation in the socially-transmitted ‘whistle’ song of Albert’s lyrebirds (Menura alberti), an oscine passerine renowned for its remarkable vocal abilities. Albert’s lyrebirds are confined to narrow stretches of suitable habitat, allowing us to map likely paths of cultural transmission...
