This species is scarce but annually in The Netherlands. A famous site to see this huge diver is along the Brouwersdam, on the border between the provinces of Zuid-Holland (ZH) and Zeeland (Ze). In the winter of 2000/2001, at least 3 individuals were seen foraging here.
Great Northern Loons do, however, turn up on different locations as well, in some cases even well inland (e.g., Gelderland, Limburg). The bird shown here was present in a little harbour near the South tip of the famous island of Texel NH, as was a fine male  King Eider. It was frequently diving for fish, but would not allow close approach. I managed nevertheless to take some videoshots using a 32x Kowa telescope. The light conditions, however, were not optimal for this, as can be seen from the far-from-perfect results. On the other hand, they do show the most important field characters.

As said, the Brouwersdam is another good place to study this species. In the beginning of the new year, I saw 2 individuals here, one of which was frequently diving close inshore. The long diving times and the short periods that it would stay surfaced made videoing very difficult, but I still got these shots:
