Caption

This is a map of the recording locations used in this study (with number of males recorded in parentheses) and the route of island colonization by chaffinches. Azores archipelago: a, São Miguel (n = 73); b, Pico (78); c, Faial (91); d, Flores (79). Canary Islands archipelago: e, El Hierro (n = 25); f, Tenerife (34); g, Gran Canaria (27). Below the map, a spectrogram of a chaffinch song from the Catalonia population, illustrating the species-specific syntax of European chaffinch song (note the unrepeated flourish syllables at the end of the song). The bars above the spectrograms illustrate how song units (syllables) are hierarchically organized into phrases.
