Male Song Repertoire Size and Syllable Sharing of Oriental Great Reed Warblers, Acrocephalus orientalis

다국어 초록 (Multilingual Abstract)

The size of song repertoires mainly provides
evidence for explaining sexual selection for female choice
as well as male-male competition. We investigated the role
of oriental great reed warbler songs (Acrocephalus
orientalis) of breeding territorial males. Early arrived males
possessed larger song repertoires, paired earlier, and
tended to become polygynous. No correlation was found
between arrival date and territory size, but polygynous
males significantly occupied larger territories than non
polygynous males. Song sharing was low among males and
the degree of similarity did not relate with spatial distance.
Our results suggest that song repertoire of the oriental great
reed warbler males play a role in female choice, where
territory quality may affect male pairing success.
