    В продолжении, по этой тёмной чайке, написали такой комментарий от Tim Edelsten:
    Looks too dark for heuglini to my eyes. Seems to have relatively slender bill; lacks white mirror on second-outermost primary; in fresh plumage, relatively small size; red gonydeal spot apparently not extending to upper mandible ...all suggest fuscus.
