Purple Sandpiper (Calidris maritima) Science Article 2 abstract Wintering Purple Sandpipers Calidris maritima were captured at Varangerfjorden, Finnmark, in March 1992, and compared with samples from Troms county in November 1988 to describe the population structure in north Norway in terms of age and sex classes, and to determine the origins of these wintering birds.

How do Purple Sandpipers Calidris maritima survive the winter north of the Arctic circle?
Purple Sandpiper (Calidris maritima) Science Article 1 abstract Winter north of the Arctic circle in northern Norway is colder, windier and there is less solar radiation than in eastern Scotland, at a latitude 13degree further south. We predicted from equations derived from heated taxidermic mounts that the maintenance metabolism (Basal Metabolic Rate plus extra costs […]

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 […]

PARENTAL ROLES AND THE MATING SYSTEM OF THE LONG-TOED STINT CALIDRIS SUBMINUTA
Long-toed Stint (Calidris subminuta) Science Article 2 abstract The mating system of the Long-toed Stint is poorly known. Observations of several broods in western Kamchatka in 1989 suggest a monogamous mating system in which incubation is shared, but with males caring for the brood after hatching Pavel S. Tomkovich, WSG Bull. 57: 42-43. Download article […]

First record of a long-toed stint (Calidris subminuta) in New Zealand
Long-toed Stint (Calidris subminuta) Science Article 1 abstract On 31 August 1997 Sheila Petch and Nick Allen were at Jarvis Road, Lake Ellesmere looking for shorebirds newly arrived from the Northern Hemisphere. While looking at a flock of recently arrived red-necked stints (Calidris ruflcollis) they noticed a bird of similar size, but with pale legs […]
