"The distinctive Old World and New World forms resulted in a split of American Pipit into Siberian Pipit Anthus japonicus and American Pipit Anthus rubescens.

Regional Record Change Logic: In western Alaska (Gambell, Pribilofs, and Aleutians) all birds are retained as American/Siberian except those specifically designated by the observer as one or the other. Elsewhere, North American and western European birds are presumed American, while those in Eurasia west to Azerbaijan, the Caucasus and the Middle East are presumed to pertain to japonicus."
