Kumlien's second cycle
观察细节
With Herrings and Ring-billed on iced pond. Initial ID's mostly by Eric Michael. 2 Kumlien's (adult, 2nd cycle) and 3 Thayer's (1 adult, 2 first-cycles). Each bird studied at fairly close range in scope for 15 minutes or more. Views from south side were best because of lighting, although more distant than from north. Besides the two Kumlien's that I document below, Eric took photos of the other Iceland individuals. The total of 5 is almost routine at this site, where the total number of foraging and resting gulls is often >1000 birds (mostly Herring and Ring-billed).
