Аннотация

Contains results of observations and collections made by the writers June 14-Aug. 22, 1953, near the Royal Canadian Air Force station at the head of Frobisher Bay. Nesting and feeding behavior is described. Incubation period was found to be about 12 days, fledgling period 12-14 days. Description and data on hatching success of 14 nests are given. The pipit was least successful in nesting of all birds of the Frobisher region in summer 1953. Principal losses, of well-developed nestlings, occurred during the third week of July when bad weather created an insect shortage. Four adult specimens collected are described.
