Use of a communal display area by Rufous Whistlers Pachycephala rufiventris
View through CrossRef
We observed a congregation of Rufous Whistlers Pachycephala rufiventris perform courtship displays toward
each other on multiple occasions, a previously undocumented behaviour. We posit that the location of the courtship behaviour
represented a communal display area and the behaviour arose either because of individuals congregating at an established
location to form pair bonds, or because the location was at a shared territory boundary where individuals gathered to defend
their territories, which led to courtship behaviour between multiple individuals. Our observations provide new insights into the
courtship behaviour of Rufous Whistlers and we suggest how future work could offer insight into the origin and function of
communal display behaviour in this species.
