Behaviour of the Buff-breasted Sandpiper at the Nest

Observations of Tryngites subruficollis on Victoria and Jenny Lind Islands, 1962 and 1966, indicate that the female, alone, incubates and rears the brood and that the species is polygamous. Brood patches were absent in males collected in June and July; however, the skin of the chin and throat of each was vascularized. A female, flushed from eggs, did not feign injury but when flying close to the observer, slowed speed by allowing legs to dangle.Comportement au nid du Bécasseau roussâtre. Des observations sur le Bécasseau roussâtre (Tryngites subruficollis) faites en 1962 et 1966 dans les îles Victoria et Jenny suggèrent que la femelle est seule responsable de la couvée et de l'élevage de la portée et que l'espèce est polygame. Des mâles pris en juin et en juillet étaient dépourvus de marques de portée, mais dans chaque individu la peau du menton et de la gorge était vascularisée. Une femelle éloignée de ses œufs le 12 juin 1966 ne se livra à aucune simulation de blessure, mais lorsque son vol l'amenait près de l'observateur, elle laissait pendre ses pattes pour ralentir

Survival Problems of the Water-Pipit in Baffin Island

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
