J.P. Mayors 1975 Journal Transsects 13.5, Barrow Alaska 24 August sampled transsects 0740-1100. Temperature at start ~35°F with heavy fog and a light SE wind. Fog dissipated intermittently and then disappeared by the time I was halfway through #1 (order, as usual, was 5-1-3) totals: 1 3 5 C. alpina ad 6 0 5 j 3 3 2 C. melanotus ♀♂ 0 0 0 j 3 4 1 L. himnodromus scolopaceus j 0 B4 7 Ploviolis dominica j 2 0 0 Phalacrocorax f ♀♂ 0 0 0 j 6 7 10 Note - Six Nycticorax chick scattered out of the 5a unit of #1 and began coursing, going in a variety of directions including down along the transect. Limnodromus are almost everywhere, irresistibly so - they are now the most abundant shorebird, or at least equal in number to alpina. During the afternoon I returned to transect 4 and finished sampling habitat fleas. It became a balmy 50°, with no clouds and several mosquitoes. Grids 2,3 25 August 0745 began cursing the grids; finished at 1215. The weather changed from 40°+ clear to 50° and raining w/ strong southern winds during the census period. GRID totals #2 #3 C. alpina ad 22 18 j 4 8 C. melanotus ♀♂ 0 0 j 22 15 L. himnodromus scolopaceus j 14 ** 91 ** Ploviolis dominica j 0 6 Phalacrocorax fuliginosus j 15 0 j 15 18 Again, as has been true since the last grid census, Limnodromus are the story, achieving incredible deviates. Most of the birds in #3 were in a flock of 35 which remained in more or less contact in the same area throughout the morning. As evidenced by the "Flyby" tally (see grid data street), Dunlins + other shorebirds are flying a tremendous amount also. A good % of these are repeated sightings of the same flocks flitting about, but many are not. Fleas is some movement in
