Birdwatching at Northern Øyeren

Nordre Øyeren Naturreservat (Northern Øyeren Nature Reserve) is Northern Europe’s largest inland delta and by many considered the most interesting birding area in the provinces of Oslo and Akershus.

Great Variety of Species
The variety of species is especially great during migration periods, both spring and autumn. In addition to the many geese, you are almost guaranteed to see some birds of prey when you visit Northern Øyeren—for example falcons, harriers, hawks, buteos, or Ospreys. White-tailed Eagle is also regularly seen.
In the early part of the summer, several places in the area where you can hear nocturnally singing warblers and crakes. Among these places are Stilla, Ringstilla, and Tuentangen, all indicated on the map. Whooper Swans can be seen all year round, but more of them are present in the area late autumn or winter. From time to time, an occasional Tundra Swan will show up among these, so be sure to examine the beaks thoroughly. Common Pochard, which is not so common in Norway, is always present in the autumn.

Årnestangen is the most frequently visited part of the reserve. Both a bird tower and a bird hide are found in the outermost parts of the spits. To get to the tip, you have to walk 3 kilometres, so you should check the water level on first to get an indication on how many birds that are out there. The numbers are in fact very dependent on the water level. Low water will nearly always give you the greatest returns.
Interestingly, as well, are the many beavers in the area, and you will see their traces on the trees. And on a good day, you will get to see the beavers themselves.

Bird Observatory and Visitor Centre
Nordre Øyeren Fuglestasjon (Northern Øyeren Bird Observatory) has been actively counting birds since the mid-1970’s and possesses a large file of information.
In Fetsund, a visitor centre for children and youths has been established. The point is market “i” on the map. Activities are regularly arranged here. You can read more on Visitor Centre Wetland Nordre Øyeren.
