Watch the live broadcast as the guillemot chicks jump out from 40-metre-high cliffs into the sea.
The annual broadcast from Stora Karlsö has now started, featuring over 70 cameras following the chicks' eventful first weeks.
On Stora Karlsö, just west of Gotland, seabirds lay eggs on narrow cliff ledges 40 metres above the sea. At just three weeks old, it's time for the chicks to leave the nest, despite being unable to fly. Instead, they throw themselves off the cliffs down to their fathers waiting for them in the sea. With their soft skeletons and extra fat on their bellies, they survive the fall.
The live broadcast can be followed via the World Wildlife Fund's (WWF) website and will continue until mid-July. Over 70 cameras are set up on the island, and you can choose which camera to watch.
"To see the chicks jump, tune in on the evenings at the end of June and beginning of July," says Mathilda Karlsson, expert on the Baltic Sea at WWF Sweden, in a press release.
The broadcast is part of the research project "Seabirds in the Baltic Sea" and as a viewer, you can report observations directly on the WWF website.
"The guillemots have constantly surprised us in different ways, so it's great that people want to get involved and observe. The observations have previously helped us discover several things, such as how the birds react to heat," says Mathilda Karlsson.
