VERMIVORA CELATA ORESTERA Oberholser
ROCKY MOUNTAIN ORANGE-CROWNED WARBLER
HABITS
Although recognized and described by Dr. Harry C. Oberholser (1905) over 45 years ago, this well-marked subspecies was not accepted by the Committee for addition to the A. O. U. Check-List until comparatively recently.
It is described as “similar to Vermivora celata celata, but larger and much more yellowish, both above and below.” Dr. Oberholser (1905) adds the following remarks: “This new form has usually been included with V. celata celata, but breeding specimens recently obtained, principally from New Mexico and British Columbia, indicate its much closer relationship, in all respects except size, with the west coast forms. From Vermivora celata lutescens it may, however, readily be distinguished by its duller, less yellowish color, both above and below, and by its much greater size.”
He gives its geographical range as: “Mountains of New Mexico, Arizona, and southeastern California to British Columbia; in migration to Minnesota and Pennsylvania, south to Texas, and Mexico to Lower California, Michoacán, Guerrero, and Puebla.”
