Подробности наблюдения
Actual count; massive movement today, apparently the result of a large low pressure system moving quickly from the Great Lakes across to the Northeast, resulting in several days of strong westerly winds. A similar event took place on November 14, 1998, but otherwise, such numbers of Franklin's Gulls in NJ are unprecedented. Small gulls, flying mainly in tight flocks, but also looser groups and singles that were likely the result of flocks breaking up as they hit the rips. Smaller, more compact than LAGU, with shorter tails, shorter wings; longer, narrower wigs than BOGU. Slightly paler above than LAGU with much less extensive black on underside of wingtips, and bold half hood of black. Most were adults, showing very small black patch on wingtip, surrounded by white. A few 1st-year bids showed dark upperside of primaries, black tail bands, and distinct whitish collars setting off black half hoods. As these birds broke out of flocks and headed into bay, they began flying in more dynamic, shearwater-like flight than is typical of LAGU.
