Calidris alpina
4+ karook on the Mcade River, North Slope, Alaska
31 May 2 alpina in the runway when I arrived. Later that evening I saw
4 at the Tryngitu grid (25,42). No display
2 June Solitary dunlin whizzed past me several times today. Found one flock
of 7 at (~28,30) on a sandy lichen ridge high above the east bank of the
river. Absolutely no sign of display yet
3 June Small flocks of 5-10 flying NE as I walk along the river bluff, one every few
minutes. None pause as they reach the bluff, dip down over the river and fly beyond
the far bank.
(25,42) again then au dunlin scold on the ground, most in small flocks. Throughout day
flocks of 5-10 have been whizzing past me. At first, all around NE. By 7 by
midday or (300 at least they again to scatter every which way. At 145 I heard
my first alpina frog call of the year. Even still, most birds are in (flocks + remain)
so all day long.
4 June movement by dunlin continued today, most headed NE. Much more display activity,
however, as some obviously paired birds
6 June dunlin have stopped moving through. Display everywhere
BARREL, Barrow, Alaska
16 June dunlin densities seems very low compared to other years.
