Stercorarius pomarinus
3 June
Saw about 4 lone birds
cruising over the area.
10 June
Not a one today.
11 June
2 birds - 1 melanistic - flying
quickly across the tundra.
16 June
The first territoriality that I
have noted: a bird on SW extension
of Gasoline Ridge and area to West. It
is covering a very large area. Lemmus
sign in the area is quite good.
