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.
Previous experience with
this & similar species:
Yes, many
