The diversity of the bird cliff – Stora Karlsö, May 2022
– Thomas Ek, Nacka
We were eight participants who gathered in Klintehamn and travelled together to Stora Karlsö with our extremely knowledgeable workshop leader Magnus Martinsson. He truly knew everything about the plants and animals of Gotland and the Karlsö islands, and shared many fascinating stories about how they are interconnected. In addition, he is, of course, also a very skilled photographer.
We arrived at Norderhamn in the afternoon to spend three days on the island. We settled into our rather simple accommodation in Norderhamn and Hien, a few hundred metres to the west. We stayed just a few steps from the beach. We began exploring the island by walking up to the lighthouse and photographing down towards the bird cliff. There were plenty of common murres and razorbills sitting on the ledges, crowding together, as well as large numbers of birds on the sea below. An impressive sight!
We spent the evening on the beach. Magnus recommended durable clothing—the rocks clearly bore traces of the birds, to put it mildly…
The water and shoreline were filled with murres and razorbills, both in the sea and on the stones.
SLEEP…
…was postponed for some of us who chose to take a late evening walk up to the lighthouse for night photography. A bit of mist had moved in, creating a very beautiful atmospheric effect.
RESEARCH…
…on common murres has been ongoing for many years, and we had the chance to meet the lead researcher who explained their work and some of their findings. They have built an artificial nesting shelf equipped with cameras and other monitoring equipment. It is 11 metres high and anchored at the top of the cliff. Researchers can climb down and access the birds through hatches. You definitely cannot be afraid of heights if you work as a scientist on Stora Karlsö!
There is plenty of food in the sea for the birds. They mainly feed on sprat, which often stay near the boundary of the deeper, more saline bottom waters at around 60 metres depth. No problem at all for the murres to reach that depth!
THANK YOU!
Time passed quickly, and it was already time to return home.
A big thank you to Magnus Martinsson and all the participants for several interesting and highly rewarding days—we will surely meet again!
