Sea eagle spotting at the Biesbosch
For a long time, sea eagles were rare winter guests, but these days they have become permanent residents in Dutch nature. This so-called ‘flying door’, with a wing span of two to two and a half meters, does not really like spectators. As such, watching it is no sinecure without thorough preparation. If you do want to see this unique and impressive raptor with your own eyes, travel to NLDelta National Park and take the information and tips below along on your adventure.
How to recognize this rare and speedy bird
With a wing span so big it covers you in shadows, it is unmistakable when a sea eagle passes above you. This master hunter has a short wedge-shaped tail, long neck, powerful legs and wide, deeply fingered wings. There is a clearly visible difference between adult and younger birds. Mature sea eagles have a white tail, a light-colored head and a yellow hooked bill. Immature sea eagles are darker in color with white spots, a narrow white strip on the inner wing, and a dark bill.Forgot to bring your binoculars? When spotting the sea eagle you can also look for the shape of the wings, which is clearly rectangular.
Where to find them in their natural habitat
There are only a few spots in Dutch nature that comply with the sea eagle’s requirements. Since nature development areas like the Kleine Noordwaard, Zuiderklip and Tongplaat were created, the Biesbosch has become one of them. They can be found year-round in the Noordwaard in particular. There are plenty of ducks, coots, big scaly fish and other animals they hunt, or from which they steal food. The views are panoramic and the trees high enough for the birds to nest, making it a popular place to hunt and nest for sea eagles, and of course perfect for you as a visitor. Please do take care not to disturb the breeding birds, shhtt...
