Aspects of bird song have been shown to correlate with morphological and
ecological features, including beak and body size, and habitat. Here we
study evolution of song length and song frequency among 30 species
belonging to the Cettiidae. Frequency is negatively correlated with body
size, and song length increases with latitude. Although migration distance
correlates with latitude, the association of song length with latitude is
only present within the non-migratory species, implying the association is
not a consequence of migration. We place these correlations in a
historical framework to show that the body size-frequency association
arose early in the group, but the latitude-song length association is more
evolutionarily labile. We suggest that latitudinal correlates of song
length may reflect increased importance of sexual selection by female
choice.
Data for Cettiidae song evolution studyRaw song measurements as well as
the ecology traits data (i. e. breeding latitude, migration and
morphology) for 30 species in Cettiidae are provided.cettiidaedata.xlsx
