Acoustic frequencies and body mass in New World doves

We studied the acoustic frequencies contained in the songs of 44 species of New World doves of eight genera in relation to body mass and habitat structure. On each sonogram, maximum (MAX), minimum (MIN), emphasized frequency (ENF), and frequency bandwidth (BAND = MAX - MIN) were measured. Log-transf...

In particular, closed habitat species use significantly higher MAX than their more open habitat relatives. This pattern contrasts with the one reported in studies based on community-wide comparisons, which in general do not correct song data for phylogeny and body mass, or include oscine species.
