GRID 3
22 July
(CoatH)
So, from the grid totals for today and yesterday, it is apparent that P. melanotus are dropping off in number, finally. Further, P. melanotus are very dense, with many moving in small groups. Today, as yesterday, I saw several individual melanotus foraging on the exposed black much-mud of receding Arctophila ponds.
23-24 July
Vegetation sampling on grid 3 sun contains unvulabated, a P. Gavia stellata
[illegible] displaying over the grid and landed upon it. Large numbers (10-15)
landed jacques foraging on the ridge W of GRID 3, and occasionally sallying over it. Duvallia are bunching up. P. melanotus down.

Several densities stand out here: Golden plovers continue to remain abundant and are dispersed in loose flocks over many areas. They seem to be using ridge sides, stand 4+19, particularly, but also are common on gasolin ridge, with its high polygonal peat, as well as spreading out into lower areas. C.alpina is flocking now + I picked up a series of groups of adults, as well as many broody birds. P.melanotus is remarkably abundant, and their habitat distribution is largely limited to hummocky
