The extreme southeast corner of Norway, in the area around Halden, has several good birdwatching qualities. For one, it is perhaps the easiest accessible site in this part of the country for finding Eagle Owl, with a few pairs breeding along Iddefjord. In spring they can actually sometimes be heard calling from Halden town centre just before dawn, just 1.5 hours driving from Oslo. This very same spot is the only reliable site for breeding Black Redstart in Norway, apart from downtown Oslo. The dense reed beds at Rokkevannet have in recent years been a regular site for booming Bittern. This site also supports Crane, Marsh Harrier and – during migration in late May – often displaying Great Snipe.
