A group of gulls at Meinypilgyno, southeastern part of Chukotka. From left to right: 2nd c.y. vegae/shistisagus, ad vegae, 3rd c.y. vegae/shistisagus, 3rd c.y. vegae, ad hyperboreus, ad vegae, 2nd c.y. vegae/shistisagus, ad vegae/shistisagus, ad vegae/shistisagus x 2 and ad vegae. At Meinypilgyno, predominantly vegae were seen but also several shistisagus and several intermediates. Interestingly, up north in Anadyr, the gull-population obviously consisted of pure vegae. In the southeast of Chukotka, shistisagus represented appr at least 1/3 of the gulls seen. At Beringovskiy in between (close to Mys Navarin), not a single vegae were seen! Comments on this would be very appreciated!
