Before you reach Kronören, you can make a detour to an old shallow and watery bay, Skärjavan. It is located east of the road in Rönnholm. In the 1930s, attempts were made to lower and ditch the lake to increase the arable area in Rönnholm's village and Skärjavan was almost drained. Already at this time, the lake was known for its unusual wetland birds and despite the decline, it has remained one of the county's most interesting bird lakes.
Today, the area is popular with bird watchers thanks to the regular occurrence of, at our latitudes, unusual species such as water rattlesnake, small-spotted marsh hen and reed warblers. Even if these would elude you during a visit, you have a good chance of seeing greylag goose, crane, songbird and barn owl. Birds of prey such as ospreys, peregrine falcons and sea eagles sometimes hunt by the lake and the area is generally very rich in species. A knowledgeable ornithologist can note about fifty species in a few morning hours if the conditions are right.
The archipelago's bird life is best experienced during the late evening and early morning in May – June.
