An analysis of the early morning period of maximum communal song (dawn chorus) at different
times of the year in an eastern Australian eucalypt forest bird community showed the following: (1) it
characteristically extended from 35-30 to 10-5 minutes before sunrise; (2) it was largely a feature of
the spring breeding season; (3) not all members of the community contributed to 1t; (4) the major
contributors changed seasonally, partly due to some species singing minimally when they had young.
