Calidris melanoto
Grid 1, NARL, Barrow, North Slope Borough, Alaska
18 June When I was last on the plot (12 June) C melanoto was not very active - see journal. That has picked up somewhat, and seems to be (is)
related to the passage of small flocks of 9 melanoto headed ENE
steadily, flying low over the tundra. So we see this movement
again. - saw at least 30 88 in singles or up to flocks of 6 flying
19 June C melanoto movement continues. It also looks as if there are quite a
few unattached 88 looking about. 2 88 in Grid 1 [neighbors
around (5,2)] are re-negotiating boundaries or one of them is
currently himself into the array. One very striking display seen
3 times - the two 88 shown along the border + rise
vertically to 75 m+ in the air. Incredibly similar to Tryngite
tandem border high flight.
20 June all the activity around (5,2) has slowed down. At least 2 88
on grid 1 are messing with localized 88. But decent photos of a
88. 88 flights continue.
Grid 4, NAKI, Barrow, Alaska
21 June So this is where they all are! See Journal, tape log. On grid
-1 from 0730-71500 too tape + photographs melanoto. It is the
biggest concentration of melanoto I have seen since 1975. Standing by the
(8,3) station I can listen to 4 88 hooping within a 200
m radius. Each of them has 1-2 88. Activity is intense + constant.
I estimate territory sizes here are <2 ha/territory. But the
concentration is not area wide, as indicated by notes above from Grid 1.
It picks up as you pass east over Caroline Ridge + get into the
low central polygon/pond area by Transect 3 & Grid 4. It
continues out over the Caves marsh through which Transect 9
runs, and goes out along Transect 10. It appears to be a
