Tryngites subborealis
At Kasook, Meade River, North Slope Borough, Alaska
1 June
(confld)
run while holding their wing up also. then Another more subtle display entails
a bird with others which stands very erect and holds its tail slightly down
They walk around like this. Also have seen aggressive crowded involving
2 birds, so also classic calidridin aggressive tail-lowering.

back in same area this p.m. placing transects. walked extensively through both sites,
but found buffle (3) only in 1: the (26,37) region near the end of Transect 8.
Active displaying.
(4,32) Meade River
5 June
2 buffle foraging on Alctowig beach at 1600
9 June
out in buffle dorm today at 1030. 1st encountered en route. 1st in same place as
last encountered in (26,37) - displaying actively but no Paralola. wing up seen,
flutter flight, and a very high flopping. the buffle displayed + fed in an area for
10-15 minutes (or less) and then flew a short distance (100 meters) to another. repeated
~ 6 times. then flew off north along the ridge, perhaps to another display site.
It looks as if the bird is adjusting its display to decreased density of birds in area,
making them visible at longer longitudinal distances.
Brothoe Bay, W. Slope Alaska

again saw a buffle cross the road, this time in the same place as yesterday, a point where the
little Potuligayak river meets close to the road, upstream (south) from its crossing. Before
I'd gotten out of the car the 1st (very big & bright) was single wing flashing + flutter jumping.
Walked over, found another 2nd + a smaller bird, probably Q. The 2nd 8* was following this
Q, paralleling mostly within 20 cm. Q ignored him I think, and flew off. That 8* disappeared.
I returned to (1st 8*) (40 m away) who remained for ~3 min + then flew (some helicopter
flight) ~70 m away to another foraging position. I left. 1030 found 8* on T-4 on river bank.
