We radio-marked 18 Dunlin, Calidris alpina (L., 1758), at San Francisco Bay, California, and 11 Dunlin at Grays Harbor, Washington, and relocated 90% of them along the 4200 km long coastline from north of San Francisco Bay to the Yukon–Kuskokwim Delta, Alaska. The Copper River Delta, Alaska, was the single most important stopover site, with 79% of the marked birds detected there. Our second most important site was the Willapa Bay and Grays Harbor complex of wetlands in Washington. The mean length of stay past banding sites ranged from 1.0 to 3.8 days. Controlling for date of departure, birds banded at San Francisco Bay had higher rates of travel to the Copper River Delta than those banded at Grays Harbor. The later a bird left a capture site, the faster it traveled to the Copper River Delta. Length of stay at the Copper River Delta was inversely related to arrival date. We did not find any effect of sex on travel rate or length of stay. Combining the results of this study with our previous work on Western Sandpipers, Calidris mauri (Cabanis, 1875), reveals variation of migration strategies used within and among shorebird species along the eastern Pacific Flyway.

Wetland Habitats

In America’s Far West, chipped stone crescents dating between approximately 12,000 to 8000 cal BP are often found associated with Western Stemmed Tradition points. Crescent function is debated, but scholars have suggested that they are closely associated with wetland habitats, an association that has never been systematically investigated. Using a geographic information system-based Euclidean distance analysis, we compared a sample of 100 geolocated crescent-bearing sites in Washington, Oregon, Idaho, Nevada, Utah, and California with reconstructed paleoshorelines. We confirmed a strong association of crescents with wetlands—94 of the 100 sites and approximately 99% of crescents themselves were located within 10 km of reconstructed paleoshorelines. Our results provide quantitative and region-wide support for a strong association of crescents with terminal Pleistocene and early Holocene wetland habitats. The diversity of aquatic habitats crescents are associated with, along with their morphology, suggests an association with faunal rather than plant resources, possibly birds of the Pacific Flyway.
