Birdwatching at Tyrifjorden North

Tyrifjorden is Norway’s fifth largest lake and is located near Hønefoss. This is Buskerud Province’s most important bird area with something to offer all year round. During migration seasons, the diversity and number of individual birds are considerably higher than the rest of the year. But also in the winter, you will find many ducks and Whooper Swans. In the summer, you will find a good number of breeding species. The area is suitable for experiencing nocturnal birds. Additionally, you can find birds of prey, particularly during migration periods. Tyrifjorden North wetlands consist of many sections that all together make up a very exciting area for birdwatchers. See map over Tyrifjorden for more details.

Great Migration
Tyrifjorden North is actually Norway’s second most important inland area for migrating and overwintering waders and web-footed birds. Thousands of geese migrate through the area every spring, many of which are Pink-footed Geese on their journey to Svalbard. Often they migrate via Gaulosen in Mid-Norway, which is an eight hour flight from Tyrifjorden.
During autumn migration, often in the end of August or September, it is not uncommon to see 100 or 200 staging Common Cranes in the same place. This has been observed many times, for example around Karlsrudtangen, Steinsletta, and Averøya.
