We are going to Gerdøya and will try to read the rings of barnacle geese which are moulting on this island. A full boat with 4 people and two bird hides. Catharina and Margje will sit in a hut with a telescope. Tessa will walk around the island and I will keep the geese on the island with the boat. The video is made during our travel to and from the island.
Above, it is a YouTube video, which starts by clicking on the picture. Below is a selfie with from left to right Maarten Loonen, Margje de Jong, Tessa Viglezio and Catharina Uth.
