A summer and a winter survey of the distribution and numbers of the Southern Crested Grebe (Podiceps cristatus australis) were carried out in Canterbury during 1980-81. Grebes stayed on the alpine and subalpine lakes throughout the year. In summer grebes moved from lake to lake within a lake system, but during the winter they were concentrated on fewer lakes and some moved between lake systems. These observations are compared with those of the Southern Crested Grebe in Australia and the Great Crested Grebe (P. cristatus cristatus) in Europe. Breeding season counts of the Ashburton lakes and the Alexandrina group during 1978-1981 indicate that the Crested Grebe population in Canterbury is stable after a possible increase during the 1970s.
