Abstract
The singing honeyeater, a nectar-feeding bird, is common throughout most of Australia. There is considerable geographical variation in weight, the heaviest birds (30 g) living at the highest latitudes (35°S) and the lightest birds (19 g) at the lowest latitudes (16°S). Clinal variation in weight is apparently related to climatic factors (e.g. potential evapotranspiration) in accord with Bergmann's rule. The exceptions are populations on islands and peninsulas which are about 13% heavier than those on the adjacent mainland.
