After cold weather returned on 14-15 June Curlew Sandpipers and Pectoral Sandpipers abandoned their clutches and did not breed again.

BIOTIC
CONDITIONS
|
| Rodents abundance evaluation: |
low
|
|
|
Breeding conditions:
|
| Numbers of Arctic Foxes were very low and Snowy Owls and Pomarine Skuas did not breed. Broods of Rough-legged Buzzards consisted of one or two chicks. Arctic Skuas and large gulls had average size clutches. Grey Phalaropes were few. Breeding success of Grey Plovers and Dunlins was low. Only Little Stint and Temmincks Stint bred successfully.
|
|
|
Rodent dynamics:
|
| An unexpected absence of lemmings resulted in high predation pressure from large gulls and skuas on clutches of waders and waterfowl.
