4:00 p.m. walked 6 of town to Nunavet Bay, after driving as far as we could along the road
going SE from the airport. Path took us successively [illegible] until hitting the slopes of the bay's
upper reaches, and we then followed the bay along its mouth slope to within 400 m of mouth
into Chukchi Sea. A gorgeous day of sunshine, light wind, and 40° temperatures.
Most of the habitat we traversed was comparable to that found within our transect/grid area,
but near the bay it developed extensive uplands - successively sloping leads into the bay - covered
with tundra not unlike unit (8,1) of T6. Vegetation is essentially the same, same that Dryas
integrifolia is common, and a few Salix reticulata are scattered about. But the real difference is
the extent of the uplands, with the sloping creek banks occupying many ha. of continuous
land. Above the rim of the banks the tundra turned to generic polygonized ridge vegetation
similar to unit (18,1) of T7 - Poa, Salix polaris. Well drained troughs. Bird
life was reduced in density in most of the upland areas we traversed, especially on
the sloping banks where only 2 species were detected, Baird and Buff-
breasted Sandpiper (1 of each) in the adjacent polygonized uplands. C. pusilla,
Calyptra, and Plovielin dominica appeared, but only the 1st of these was "numerous"
and then specifically in our location near the edge of the sloping bank. Some pusilla were
seen flying between upland polygonized areas down to the water's edge on the bay. We
saw no pusilla before reaching the zone adjacent to the edge, even though some of
the habitat we traversed was good mixed pond + polygon. This reaffirms Frank's
contention that pusilla depend upon this sort of juxtaposition of habitat types. Gobs of
Emeletus and P. fulviviridis moved through the lowland Carex marshes.
1 July
Transects today: I ran 6-10 while Dave Shufford sampled 1-5. Weather 33° at 0600
rising to 41° by 1430 when we returned. Fog, NE wind, clearing by 1100 to a sunny, cloudy
day. The tundra is drying, ponds receding, flowers emerging. Found blooming Potentilla today
and one Papaver in flower. Birds are moving through. Large flocks of Plectropterus
mixed with Black Phalarope and a few dunlin were wheeling over the tundra - up to 410
birds in a flock. Gooline Bridge was teeming w/ birds: 28 Pectorals, 17 Dunlin in 10 ha.
