A fox was working part of the transect, and appeared to successfully get someone's egg or young.
(judging from its behavior). I am somewhat surprised by the # of flocking darwins evident
already this year - birds that obviously are no longer breeding. According to Kay Everett,
the storm which rained on Prudhoe for two days while I was there also hit the foothills
with 4 inches of snow at Toolik Lake. Hansen's people at Franklin Bluff
reported 100% mortality for Calcarius during that storm. So now we have a large
Dulin moving through, and also non-breeding Q melanota. Are their unusual
numbers a result of the storm?
2 July
walked out to end of TIO taking ItzD data from 0730-1130. Then until 1400 scanned for
nest on GRID 1. Weather began well, with 33° and a moderate E wind dropping
to a light wind, all with 100% sun. But the wind shifted to a northeasterly direction and the
temp fell perceptibly, perhaps because it also increased. Anyway, returning to the lab saw a
pair of Aythya affinis - Scap with definite bump to profile and white
speculum fading quickly on the shoulder primary coverts. Dave Shuford, who has
much more experience of Aythya spp than I, got excellent view of the birds. He went
out later with a scope + reported he will clean of the usual A. marila marking.
There were also 3 Polysticta 9Q there, and there also was a flock of Polysticta 9Q
out near Duck Camp. Unusual territory that may relate to strange movements
by other birds - i.e. a massive breeding failure.
GRID 1 - last year's GRID 2
3 July
0430-1245 censused GRID 1. Weather shitty: 33°, snow, sleet, moderate N wind picking up through
morning 100% low clouds, fog at exact clearing up rising wind until ultimately sunny. Very
fierce del Fuego in weather quality, with patchy overlying followed by scratches of another. Bird
activity on the GRID miserable, at least in terms of totals.
