Birdsong is often regarded as an aggressive signal. More specifically, particular singing
behaviours are hypothesized to be threatening, including song type matching, frequency …

Communication and social behaviour are inextricably linked, with communication mediating
important social behaviours such as resource defence and mate attraction. However, the …

Publisher Summary This chapter discusses on how birds respond to each other and the
proximate and ultimate consequences of different singing strategies during an interaction …

Analyzing the function of song and its evolution as a communication signal provides an
essential backdrop for understanding the physiological and neural mechanisms responsible …

Birdsong provides neuroscientists with a uniquely powerful model for studying imitative
vocal learning in a system where the brain structures responsible for song learning and …

Bird song, like many other male secondary sexual characters, may have evolved as intra-or
inter-sexual signals of male phenotypic quality. The hypotheses that song rate and song …

In our study population, neighbouring song sparrows typically share two or more of their 6–
10 song types. In an earlier experiment, we found that established neighbours typically reply …

Song–type matching is a singing strategy found in some oscine songbirds with repertoires of
song types and at least partial sharing of song types between males. Males reply to the song …

Song repertoires may be a product of sexual selection and several studies have reported
correlations of repertoire size and reproductive success in male songbirds. This hypothesis …

A male song sparrow, Melospiza melodia, has a song repertoire of about eight or nine
distinct song types, and he typically shares several of these song types with each of his …
