Lagopus Lagopus 6 July Pleade River Coal Pluio, 157°25'W, 70°29'N. A lot and did her best to be fierce. When we went off, she ran ahead of us for about 50 metres, then went back to the nest when we walked away from her. 8 July Flewled the F from the nest by the river plot near the W end of Phil's transect.

Later flewled a 0 from a clump of Sibirian plucking on a sphagnum dyke by the edge of lake Agassiz. It was covered with mos- quitoes on the head, but the body didn't seem to be attracting much.

I opened one of these but found oddly yolk, and as the other was also infertile. 11 July Flewled a F from a trough in Eriophorum- Carex area near south ridge. The 0 soon swooped off east by 8 gave a low intensity threat display and remained in this area. I searched
