Pied Avocet (Recurvirostra avosetta) Science Article 3 abstract After the breeding season Pied Avocets Recurvirostra avosetta gather at moulting sites. Counts show that some of these sites host large parts of the total population, but it is not known how many individuals use a particular site over a season (volume of a site). Here we […]

HABITAT SPECIFIC BEHAVIOR OF THE PARAKEETAUKLET IN THE BARREN ISLANDS, ALASKA
Parakeet Auklet (aethia psittacula) Science Article 1 abstract We are not aware of any published accounts of the behavior of the Parakeet Auklet. Previous studies of this species have centered on its ecology in the Bering Sea (Bedard 1969a, 1969b, Sealy 1968, Sealy and Bedard 1973). Our intent is to discuss and relate the basic […]
Effectiveness of predator exclosures for pectoral sandpiper nests in Alaska
Pectoral Sandpiper (Calidris melanotos) Science Article 1 abstract During the summer of 1992 we placed wire-mesh exclosures around 13 of 52 Pectoral Sandpiper (Calidris melanotos) nests near Oliktok Point on the North Slope of Alaska. Exclosures were 66-69 cm in diameter, 31-cm tall, and were made of 5 X 10-cm mesh weld-wire with 3-cm mesh […]

Comparative foraging ecology of planktivorous auklets in relation to ocean physics and prey availability
Parakeet Auklet (aethia psittacula) Science Article 2 abstract tested the hypothesis that the spatial distributions of foraging least, crested and parakeet auklets (aethia pusilla, A. cristatella and A. psittacula, respectively) in the shallow passes of the Aleutian Islands would be determined by physical mechanisms that control near-surface prey concentrations. We recorded currents using an Acoustic […]
