This 2018 video is called Field work at Zackenberg research station (East Greenland).
Translated from the blog of Dutch biologists doing sanderling research near Zackenberg, Greenland; where there are are more lemmings this summer than usually:
All five [Arctic] fox dens in the research area are occupied and there are little foxes inside. In one den even seven baby foxes, a record. The long-tailed skuas also respond to the food bonanza this year, we have already found 11 nests and each of those contain two eggs, where only one egg per year is usual for these predatory gulls. We have also seen many long-tailed skuas tearing lemmings to pieces.
Good season
It promises to be a very good season with so many lemmings and, as a consequence, little predation of sanderling clutches.
This is a video in Dutch about ringing sanderlings in Greenland.
