Winter is coming. At Revtangen bird observatory south of Stavanger that means time for action, but fortunately of a peaceful nature. Autumn is high season for bird ringing when it comes to migratory species like waders.
The first building at the observatory was built in 1937, and it was officially opened in November the same year. The observatory is run by Stavanger Museum, and the main task is catching and ringing of wading birds and passerines. Stavanger Museum is also organizing all other scientific bird ringing in Norway.
The observatory had some troubled times during WW2 as the German occupants fortified the area and destroyed parts of the buildings. And early in the 1950s the Norwegian Air Force set up a firing and bombing field within the catching area at Revtangen. The observatory cabin was therefore moved closer to the main road, where it is located today. This is also the main area for catching and ringing of passerines.
Catching and ringing of waders take place on Revtangen itself, a small shoal extending into the sea at the westernmost point on Jaeren. At low tide this is a rich food source. Between 1000 and 5000 migratory birds are tagged here each year, and almost 300 different species have been observed in the area.
