J P Myers 1975 Journal Burrow Spit to Nuwak + Plower Pt. 12 August out 1830 went on 3-whaler to the end of the spit, travelling out the Chukchi side. Weather was incredibly balmy - 39° with sun and no clouds. This changed abruptly as a westerly wind picked up, and around 2115 we were socked in by a thick + wet fog. East out, however, the sea was glass. Xema sabini + Phalaropus fulicarius were the two most common birds along the Chukchi side, hundreds of the former + 2000+ of the latter. Both spp were foraging within a meter of shore, picking off surface + subsurface crustaceans + gannets through the "splash" zone for stranded bugs. Very few auks - a small flock of Sora stellula, a few Sora specklealis, and ~50 Clangula h. At the point (Nuwak), on the long thin tendon pool, we saw 200 Phal. fulicarius, 50 C. alpina, 10 C. pusilla, 6 C. melanotos, 5 C. mauri, ~50 Xema, 10 Arenaria interpres. We searched diligently for Rhodostethia, and found only 4 juveniles (Excellent looks at them all, beside juvenile sabini's for comparison) along the spit almost halfway to Plower Pt from Nuwak. Along this stretch of beach the sheiks were on the downwind (outer) side, again foraging in the littoral. Over 1000 fulicarius along here, ratio of adult : juvenile fulicarius in on the order of 1:10. One flock of ~200 Sterna paradisaea foraging almost all the way to Plower Pt, hovering ~100 m off shore, plunging + surface dipping from the air. Grid 2, transect 3 13 August Began cursing (ratio 2) at 0830 - moderate westerly wind with a low and thick fog. Temp. on the order of 38°F. Census totals: ad. 16 C. alpina juv. 5 ad. 2 C. melanotos juv. 3 ad. 8 Phuvialo dominica j. 8 Phalaropus fulicarius 21 The snowy owl & clocks are still in the lower left-hand corner of the grid, which happens to be G. Baty's trapping area, as well as being daisies + some polygonize the the other regions. The fact of the definite habitat difference makes it difficult to say whether the owls' presence is solely responsible for the lack of shorebirds. It is also true that local areas vary
