Weather conditions: |
| Spring was early and warm. First Bean Geese appeared near Chokurdakh already on 7 May. Weather became adverse from 25 May to 1 June, when tempereture droped to -10øC with snowfalls and snowstorms. With warming upon 2 June birds started to arrive in mass (14 species recorded). Peak of migration was reached on 5-6 June, when numerous Steller's Eiders were passing and waders migrated in flocks of 20-50 birds. Among identified waders 90% were Red Phalaropes. Dotterels, Curlew Sandpipers and Sharp-tailed Sandpipers were seen only on migration. Snow completely melted off by 10 June.

All known dens of Arctic Foxes were occupied, and pups were recorded from mid July onwards. Stoats were abundant. Rough-legged Buzzards started nesting early: a clutch of 2 eggs was found on 22 May.
