Article Type: Paper
Results are given of a monthly survey of birdlife in the subalpine Lake Harris basin, north-west Otago Alps. Fluctuations over a year, from May 1976 to April 1977, were tallied by species and by numbers of individuals. Comments are made on effects of climatic conditions and resources available to birds at such altitudes in the Southern Alps along the Main Divide. Arising from observations made so far, it is suggested that the Rock Wren (Xenicus gilviventris) may hibernate during harsh winter months.
