mostly checkered, primaries mostly whitish with dark arrow marking on shaft.

Similar
species and
how were they eliminated: |
Thayer's are rather similar, and much debate exists whether they are distinct species or just sub-species, with many inter-grades that cannot be safely assigned. Whether or not they are species or sub-species, this was a fairly classic Kumlien's. A Thayer's was nearby for direct comparison, solid dark tertials and dark blackish-brown primaries with pale edging noted, as was darker brown checkering throughout. |
