Summary of the 2020 season

The 2020 ringing total at Revtangen BO stopped at 7598 birds. Most were ringed in the trapping garden around the station, but a little over 700 were trapped at Revtangen, where the trapping effort was concentrated at shorebirds and storm petrels. In addition, 2859 birds were ringed by our volunteers at locations away from Revtangen BO. Most of these were ringed by Renate and Atle Espen at their family cottage at Justöya in Agder.



Little Bunting had the best occurrence ever with 4 birds ringed.

The spring was generally cold, in particular March was poor and May was also dominated by northerlies and westerlies and generally few migrants around. July was also wet and windy, as was most of August. From late September and through October blue tits was a big problem, arriving in numbers never before seen. Trapping was seriously hampered by this, as the covid-19 situation prevented us from bringing in enough volunteers to handle the situation.Therefore, we could only trap with a limited number of nets during tohe most important part of the autumn.



This young European Shag was caught with light during a nightly storm petrel ringing session.

Our handful of dedicated volunteers still made a fantastic contribution to the season by ringing around 700 shorebirds and a good number og storm petrels at Revtangen. The Bar-tailed Godwit colourringing project had 78 new birds added, a great result. 58 other waders and around 100 gulls were also fitted with colourrings. Two species were trapped and ringed for the first time at Revtangen BO, European Shag and Citrine Wagtail. Eurasian Nuthatch was the only species with notable irruptive movements, with 21 birds ringed.

A big "Thank you!" to our volunteers, let's hope 2021 will allow us a more normal season.
