Dark morph something. It was in with TUVUs. Didn't get a digibin as the kettle moved over treeline quickly. Dark body, lighter gray barred wings, barred tail. Didn't have notable tail bars but tail was not solid colored. Light legs. Slightly dark wing tips. Very shallow flaps. Claire and I both independently did a field sketch afterwards. My first impression was the most WTF option (ZTHA), but we also considered dark morph BWHA (which is good for the petite impression, obviously different from TUVUs) or dark morph RLHA (but it didn't have obvious tail marks or obvious contrast at wrists). Argh!!
