Description
Summary:"Two disjunct breeding populations of Whimbrel Numenius phaeopus have been described in the western hemisphere (American Ornithologists’ Union 1983). The western population breeds in portions of Alaska and across the Yukon and Northwest Territories of Canada while the eastern population breeds west and south of Hudson Bay (Skeel & Mallory 1996). Most of what we believe we know about the migratory pathways of these populations has been pieced together from circumstantial evidence gleaned from decades of field observations (Skeel & Mallory 1996, Taverner 1942). The populations have been thought to have separate migratory routes with little mixing where the western and eastern populations were confined to the Pacific and Atlantic Coasts, respectively. Here we present evidence of a transcontinental migration route that brings portions of the two Whimbrel populations into contact during spring migration."
