"Observations of the status and numbers of Northern Fulmar Fulmarus glacialis, Glaucous Gull Larus hyperboreus, Black-legged Kittiwake Rissa tridactyla, and Thick-billed Murre Uria lomvia were made at Prince Leopold Island, Lancaster Sound, Northwest Territories, Canada by a 5-man team from 18 July to 8 August 1988. Timing of laying and breeding performance of three of the four species seemed normal: Glaucous Gull, Black-legged Kittiwake, and Thick-billed Murre. In contrast, few Northern Fulmar pairs appeared to have produced an egg, but those that did hatched their young close to the normal time. Reduced productivity by fulmars is not unusual when conditions such as ice break-up is late. But in the past, when such poor breeding performance occurred in fulmars, there were corresponding failures or delays in timing of breeding by the other species. Data showing these inter-specific differences are presented, as are details related to the study plot monitoring system now in place at Prince Leopold Island and other topics of the 1988 study exercise"--Abstract, p. 1.
