Effects of Weather on Reproductive Success of Birds at Churchill, Manitoba

Abstract

Describes the effect of a severe wind and rain storm, 8 July 1965, on passerine bird nestlings in this area. Mortality from exposure was high: there was little evidence of starvation. The weather did not effect nests with eggs only. Non-passerine species appeared largely unaffected by the storm. The altricial condition of passerine young may account for paucity of arctic passerine species.
