But further evidence is still needed to confirm the westward extension of spectacled eider, long-billed dowitcher, and sharp-tailed sandpiper.
The sharp-tailed sandpiper (Calidris acuminata) is much rarer and has been found breeding only once, close to Tiksi (Kozlova, 1962).
No radar echoes were identified, but observations at field camps on the tundra provided valuable information: Many waders, such as pectoral sandpiper Calidris melanotos, grey phalarope, curlew sandpiper, dunlin Calidris alpina, and sharp-tailed sandpiper Calidris acuminata, were assembling in small postbreeding migratory flocks at tundra pools.
According to the field reports, the most important species to take part in the easterly movements were grey phalarope, curlew sandpiper, pectoral sandpiper, dunlin, sharp-tailed sandpiper, grey plover, and also ruff and little stint (see below).
Rare visitors such as
