Occasionally on sandy beaches and rocky shorelines. Habitat. Low altitude montane tundra in subalpine belt, on mossy and scrubby tundra, usually in rather dry and raised areas. During non-breeding season, mostly coastal, on intertidal mudflats, shelltered inlets, bays and lagoons, but also commonly on wide variety of freshwater, brackish and saltwater wetlands. Occasionally on sandy beaches and rocky shorelines. Food and Feeding. On breeding season mainly beetles, insect larvae, Hymenoptera and tiny seeds. May forage far from nest in wet habitat. Outside breeding season, small invertebrates, such as polychadgd worms, crustaceans, insects and molluscs, also seeds. Constant pecking motion, like C. minutaa, probes in sediment to depth 2 cm, or jabs, also gleans. Feeds in dense flocks. Birds spread out during feeding, but come together when flushed. Breeding. Jun-Jul. Monogamous. Low degree of site fidelity. Nest is shallow depression lined with leaves and grass. 4 eggs, single brood, but replacement clutches laid. Incubation 20-22 days, by both parents.

Uses several stopovers, mostly on coasts of Japan, Korea, SE China, Taiwan, Hong Kong Vietnam, Malaysia, indonesia, New Guinea, Philippens and Micronesia. Migrating flocks crossing Pacivic often stage on islands.Most of population breeding in Alaska appears to pass through Aleutian and Pribilof Is to migrate with Siberian population. Some spend boreal winter in the Americas. Australia reached by late Aug and arrivals continue until Nov. Status and Conservation. Not globally ghreatened. Australasian population estimated at 500.000 birds. Israel. In Israel subspecies Calidris ruficollis. Straggler. One recorded on Apr 2003 at Kibbuz Lotan near Eilat. (16.5.1989). |
