WEATHER
CONDITIONS

|
|
|
Weather conditions: |
| Generally it was a late, cold and windy season. Arrival and nest initiation dates by birds were later than in the previous two years. The late start potentially was the cause of the low renesting frequency. We found that many shorebirds which nests were depredated late in incubation did not renest.

Breeding conditions:
|
| Arctic Foxes were common, while the American Mink was abundant. Pomarine Skuas and Rough-legged Buzzards were not recorded; Short-eared Owls were rare and did not breed. Long-tailed Skuas were common breeders, and Arctic Skuas were rare. Willow Grouse bred in high numbers, and the Dunlin occurred at a density 57 nests/km2.
