Number of Occurrences21 - 300
Rank Reasons
Better information is needed on its actual population number but assuming 800,000 is an accurate estimate of this species' numbers then G5 is an appropriate ranking.
Range Extent Comments
BREEDING: northeastern Alaska across northern Canada to northeastern Manitoba and northern Ontario, and probably locally south to borders of taiga; north to Victoria and Jenny Lind islands, Northwest Territories. NON-BREEDING: primarily in South America (mainly Bolivia and southern Brazil to northern Chile and northern Argentina), casually north to southeastern California, Gulf Coast and Florida (AOU 1983).
Occurrences Comments
This species is found only in North and South America and there is differences in opinion on the actual population numbers of this bird. Hence the large range limits for number of element occurrences. Depending on the source, the populatoin size of this bird ranges from 200,000 to 800,000 (Morrison, et. al. 2006).
Threat Impact Comments
The recovery of the Canada Goose and Snow Goose may be harming the Stilt Sandpiper on its breeding grounds by altering the tundra habitat (National Audubon Society, 2014). Wetlands destruction continue at a rapid place in many places along the migratoin route for this species. Climate change may impact this species northern latitude breeding grounds.
Ecology & Habitat

Habitat

Nonbreeding: mudflats, flooded fields, shallow ponds and pools, and marshes (AOU 1983). Nests in sedge tundra near water, often near wooded borders of the taiga (AOU 1983), on the ground in a shallow scrape, often on a slightly raised site (e.g., atop small sedge hummock or on low well-drained gravel ridge crossing sedge meadow). Tends to return to same nesting site in successive years.

Ecology

During migration often seen in association with dowitchers and greater and lesser yellowlegs. Forage up to 8 kilometers from nest (Jehl 1973).

Reproduction

Egg laying peaked during the second week of June on Victoria Island. Both sexes (male by day, female by night) incubate 4 eggs for average of 20 days. Hatching peaks in early July. Nestlings are precocial, leave nest soon after hatching, independent in about 14 days (fledging period reported as at least 17 days). At Churchill, Manitoba, nesting density was 5-25 pairs per sq km (see Johnson and Herter 1989).
