Abstract
Annual fluctuations in the autumn population size of the capercaillie T. urogallus at Vegarshei in South Norway, 1920-1970, were analyzed statistically in relation to various meteorological factors to discover short-term effects. The most important weather variables which coincided with a high population size were: an early snowmelt in spring, only a few days of rain at the time of egg-hatching at the beginning of June and only a few days of rain in July. These factors may have operated through their influence on the production of young. Data on the species from other countries are discussed.This publication has 2 references indexed in Scilit:
