Breeding conditions:
|
| Arctic Fox met only once. Buzzards and Snowy Owls were absent, White-tailed Sea Eagle nested, and preyed upon Ruffs (remnants found). All 3 skua species were regularly met, but breeding not observed. In the very beginning of June Red-necked Phalaropes, Ruffs, Wood Sandpipers, Temmink's Stints, Pectoral Sandpipers, Long-billed Dowitchers, Common and Pintail Snipes started breeding, when a fraction of Red-necked Phalaropes and Little Stints still migrated. Red-necked Phalaropes, Ruffs, Temmink's Stints, and Long-billed Dowitchers were abundant breeders, while other species - rare. Little Stint was not found nesting.
