Formal Taxonomy

Animalia - Craniata - Aves - Charadriiformes - Scolopacidae - Tryngites - breeds in western Chukotka (Russia) and migrates along the coast of the Pacific Ocean (in contrast to the interior of North America), but no banding, morphometric, or genetic studies have been conducted to define the differences between western and eastern populations.

Short General Description

A medium-sized sandpiper.

Migration

false - false - true - This sandpiper migrates as singles, pairs, or occasional small flocks. It may concentrate at particular staging areas. Variation of habitat use may coincide with changes in local food abundance or other conditions. Adults and juveniles may use different migration routes (Lanctot and Laredo 1994).

Food Comments

Feed primarily on insects (adults, larvae, and pupae) (Bent 1929, Palmer 1967). Also eat spiders, mollusk species, and seeds of aquatic plants (Bent 1929). On breeding grounds, foods consist of terrestrial invertebrates, especially the adults and larvae of beetles and the larvae and pupae of dipterans (Johnsgard 1981). Diets differ from other arctic shorebirds because this species tends to occupy upland habitats (Lanctot and Laredo 1994). As a result, diets are highly dependent on insect larvae and adults, feeding less on Chironomidae larvae and other wetland invertebrates (Lanctot and Laredo 1994).

Reproduction Comments

Males and females arrive simultaneously on the arctic breeding grounds late May through early June (Lanctot and Laredo 1994). Lek breeding system (Sutton 1967, Johnson and Herter 1989, Lanctot and Laredo 1994, Lanctot and Weatherhead 1997). Leks change location from year to year. Within 2 to 11 days of arrival, males begin to display together on leks. Approximately 2 to 20 males occur together in a lek, although some males may display in solitary locations (Lanctot and Weatherhead 1997). Females visit leks only for copulation (Sutton 1967). Males and females do not pair (Johnson and Herter 1989). Males may mate with several females but take no part in incubation, leaving the breeding grounds in mid-June to early July (Parmelee et al. 1967, Sutton 1967, Lanctot and Laredo 1994). Females lay a single clutch per year (Lanctot and Laredo 1994), normally consisting of 4 eggs (Harrison 1978, Johnsgard 1981, Godfrey 1986). Incubation lasts 22-25 days (Troy 1988 in Johnson and Herter 1989, Lanctot and Laredo 1994). Peak hatching during second and third week of July, although hatching has been documented as early as July 5, 1992 and July 4, 1993 (Lanctot and Laredo 1994).

Ecology Comments

Gregarious. Nonbreeding: roosts at night in flocks often of about 600-1000; often seen in mixed flocks in association with golden and upland sandpipers, or Baird's or pectoral sandpipers (Stiles and Skutch 1989). Many defend small feeding territories in winter, but they roost in monospecific flocks (Hayman et al. 1986). <br><br>Breeding densities are low and can vary dramatically from year to year; in Alaska, densities were 0.5-14.0 individuals per sq km from 1981 to 1989 (see Lanctot 1995).

Global Range

H - >2,500,000 square km (greater than 1,000,000 square miles) - H - Breeding range encompasses the low and high acrtic in eastern Russia, northern Alaska, northern Yukon, northwestern Mackenzie, and the region fromBanks, Melville, Bathurst, and Devon islands south to southern Victoria, Jenny Lind, and King William islands; the bulk of the breeding population appears to occupy coastal portions of the Yukon and Northwest Territories and most of the Queen Elizabeth Islands (Lanctot and Laredo 1994). During the nonbreeding season, this species occurs in South America (Brazil, Uruguay, and Argentina). Due to destruction of native grasslands by agriculture, most winter in coastal portions of the Río de La Plata grasslands where livestock grazing maintains suitable habitat. Migration in the United States is mainly through the central plains; juveniles are more common along the east coast in fall migration, rare along the west coast during southward migration.
