Abstract

During the years 1954-70, 230 pintails (Anas acuta) banded in North America were reported from eastern Asia, primarily Siberia. Most of the birds were shot on the breeding grounds in May. The movement into eastern Asia of pintails banded in the interior of North America was directly correlated with the overflight of the southern portion of the breeding range in North America (r = +0.73**); this overflight resulted from drought conditions (Smith 1970). Thus, the magnitude of the pintail movement into eastern Asia is believed to be dependent upon water conditions some 3,000 miles away. A higher percentage of the pintails banded in the west was reported from eastern Asia, although the recovery rate index was not significantly correlated with the percentage of pintails found in northern Canada and Alaska (r = +0.46 NS). Apparently, a portion of the pintails which winter in the western United States annually nest in Siberia, regardless of water conditions on the North American breeding grounds.
