The 7th primaery of juvenile clanga (the birds in your links Motmot) is shorter than on older birds. On older birds the 7th primary is a decent feature, even though of course nothing to base the ID on by itself.Also, in older GSEs the coverts ARE often paler than the flight feathres. Again quite normal.The black carpal patch looks better for clanga. The single pale carpal comma might also suggest clanga although this is variable.Structure, with quite broad based wings, broad wingtip and string head has more the feel of clanga to me. But there's a lot of variation and it's difficult to judge in photos sometimes - and in the field!Having said all that, looking at the photos again the 7th primary actually looks a little short for clanga. And the upperparts look better for pomarina. The primary blobs on the upperwing are more like the typical pomarina pattern (on clanga usually less of a blob and more diffuse).So a rather tricky individual. A good one to sit on the fence on <img src="data:image/gif;base64,R0lGODlhAQABAIAAAAAAAP///yH5BAEAAAAALAAAAAABAAEAAAIBRAA7" class="smilie smilie--sprite smilie--sprite2" alt=";)" title="Wink    ;)" loading="lazy" data-shortname=";)" /> Possibly a dark pomarina after all. A better look at the upperparts maybe will help.</blockquote>
