Abstract

The breeding biology of the bell miner (Manorina melanophrys, Meliphagidae) at a site 60 km east of Melbourne, Victoria, is described. Bell miners showed a clear seasonal pattern of nesting, moulting and development of brood patch. Increased food availability and number of helpers were not associated with increased nesting success. This is partially explained by increased predation on nests in colonies with more helpers. Growth rates of nestlings did not increase with increased number of helpers and habitat quality, although these variables may affect postfledging survival rates. Breeding females organised into neighbourhoods seemed to be able to synchronise nesting. Egg shape differed among females but egg size did not, although egg volume increased as the breeding season progressed.
