storholmen

12 June 2021 14:00

Storholmen is the biggest island in the fjord and usually with many goose and common eider nests. It is a beautiful sunny day, but due to the late season with lots of snow, the number of nests on the island is low. We count this first day 229 goose nests and average clutch size is only 3.0 eggs.

We take pictures of the clutch to measure infestation rates with nest fleas. This nest is heavily infected.

Several nests have different sets of eggs.

This might be egg dumping by another female. Here it is clear as the extra green egg is from a common eider duck.
