American Pipits are one of the more common North American passerines found in the Pribilofs. A pair actually bred near Crater Hill in the summer of 2001. Two distinct subspecies occur, with the Siberian breeding race, Anthus rubescens japonicus occurring in fall (September through mid October), and the American subspecies occurring in early spring (mid May to very early June) and fall (mid August through mid September). Many authorities anticipate that the japonicus form will soon be split from the North American forms. The japonicus Pipits are more heavily streaked below, especially along the flanks, possess two bold (usually) white wingbars and have pink legs. Alaskan breeding American Pipits tend to be buffier below, with reduced black streaking, buffy wingbars and black legs. Both forms can be safely separated from Red-throated, Pechora and Tree Pipits by the lack of white back braces, and from Olive-backed Pipit by their lack of a clean white throat, bold white supercilium which is yellow/orange in front of the eye, and the white lower belly.
