    seen spectacular climbs of polar foxes into the cliffs And Arjen Drost observed even a polar bear looking for food At Alkefjellet on the east coast of Spitsbergen he made these pictures after first observing the base jump of cliff nesting barnacle geese The stories about polar bears exploiting new food sources are highly relevant for this species adapting to or suffering from climate change home weblog science people station

    meadows and this was a risky operation There was an old clip from Greenland but this year there is new material showing the risk of the goslings jumping from the clip Pictures from Arjen Drost and a video from Animal Planet show the dramatic jump Since 1943 there has been a dramatic increase in goose numbers on Spitsbergen A 150 times increase due to better food in winter and conservation measures like a hunting ban and nature reserves To accommodate this population increase barnacle geese started breeding on small islands These islands were most often not visited by polar foxes and breeding was safe Also in Kongsfjorden the islands in the fjord were populated with barnacle geese since 1982 and the nesting numbers increased to 680 in 2013 In recent years thanks to a study of Jouke Prop we learned that the it was only a few decades that islands were safe for nesting as a new predator appearred on stage the polar bear In summer it had disappeared from the west coast of Spitsbergen due to heavy hunting But since 2000 it has become a regular visitor again We are still unable to distinguish between three different causes The hunting ban since 1968 might have supported a population increase Or the bears might have become less shy for people and tourists Or the bears are stuck on land because the ice is moving further away in summer Despite all stories about climate change and scientific and public attention for the fate of polar bears local scientists are unable to make statements about the importance of each of these three hypothesis Nevertheless at this moment most barnacle geese on Spitsbergen are nesting on small island and at least these birds escape the danger of base jumping However cliff nesting is

    for new additions Polar bear impact on Barnacle Geese Throughout their range polar bears make increasingly use of alternative food sources Bird eggs for example may be a substitute when the preferred prey seals is not available The impact of polar bears on the breeding success of colonial breeding birds can be huge In a colony of barnacle geese on West Spitsbergen Svalbard only few nests escape the raids of the bears Safer research in polar bear areas Polar bears are known to destroy huts or tents in search for food In polar bear areas camps need therefore a good protection to keep hungry bears out Our study site in Spitsbergen is frequented by polar bears in summer Over the past years we have favourable experience with electric fences surrounding our tents This video shows how polar bears respond to the protected camp 1 curious without further interest as occurs most often 2 coming close to the electric fence without touching and 3 touching the fence when attempting to enter the enclosure For adequate protection the electric fence should be used in combination with other means to detect and scare polar bears Polar bear playing with seeweed Polar bears were not our best friends when they came to spoil our bird studies Nonetheless they are impressive animals and exciting to watch We forgot about bad feelings when observing this old male playing in the water and using kelp as rubber duckie Polar bear in barnacle goose colony A polar bear is about to depredate nests of barnacle geese and eiders in a colony at the west coast of Spitsbergen Svalbard Polar bears on Spitsbergen love goose eggs More and more while studying geese on Spitsbergen Nordenskiöldkysten we observe polar bears Here you see how they pass our tent The bears
