Behaketaren xehetasunak
Photos show 3rd cycle, 1st cycle, and one of the 2nd cycle. A quick check of my photos did not produce an image of the second 2nd cycle. Birds identified by structure and plumage. All were bigger than RBGU but smaller than HERG, which they were closer to in size. Rounded head and smaller bill contrasted noticeably with adjacent flat-crowned and large-billed HERGs. THGU also had shorter legs. Appearance of tertials, coverts and primaries also used in identification. Birds initially located by Amar Ayash.
