JP Myers 1980 Journal Grid 3, NARL, Barrow, Alaska 19 June (cont'd) The transects yield a 50% cover date of ~11 June, compared to 13 June (1976), 9 June (1977), 10 June (1978) and 6 June (1978). On the other hand, the 100% value persisted on late this year as in the latest year- 1978 - through to 4 June. And the cold was impressive. Anyway... after tracking the & I returned to camp at 0700, then came back out at 0830 to track again. Remained until 1430 tracking another &. Action on the Grid is continuing to pick up with more & around than ever. We found 2 more melenator nests each with 2e (although one had a 3rd egg by 1100). And the weather even again baling -38°F, no clouds, ad until 1200 no wind. 2200 I returned to the field once more, this time to 0610 3 aL once again to 20 June tracked a & melenator. Remained out until 0800, tracking from 1100-0500. No clouds and temp remaining between 0°C and 2°C. The wind was from the NE @ ~10 mph when I went out; it fell to <5mph for 2 hrs around 0300 but picked up to 12-15 by 0700. Made life a bit cold. The female & tracked populated at 0317 - see tracking account and melenator account. Its last night action was continuous, although it affected cibated between 0300-0430, particularly in melenator and alpina. Pluvialis dominica displayed all night. Grid 3 is a rich area this year - see census results. Then an obshtichum, C. mauri, C. pusilla, C. bairdii, C. alpina, C. melenator, a pair of C. canutus is seen almost every day. Also flamencus hunts them occasionally. And in the lowlands to the East from the ridge we have a thick lowland community of ducks and shorebirds, including at least 2 pairs of Anser albifrons - very atypical for Barrow. Polysticta stelleri is abundant this year, so is Anas acuta. In fact the duck seems as impressive, as good a year in numbers as 1976, the year of the prairie drought. It may be better than that year insofar as actual breeding densities are concerned, particularly in Polysticta and Anas acuta.
