Revealing new research has shown how an endangered seabird is converging on specific stopping off points in the Atlantic Ocean during migration, helping scientists to better understand the bird’s conservation needs.
Migrating birds can face a wide range of challenges. Whether they are crossing seemingly endless deserts, flying over towering mountains or traversing vast open seas, these hardy globetrotters often need to navigate more than simply the landscape beneath them.
Sudden changes in weather conditions, pressures from hunting and the appearance of human-made infrastructure can all play a part in disorientating, diverting or delaying the long-distance travellers. Migration is not always as straightforward as getting from a starting point to an end destination; the route taken is often every bit as important as is the availability of suitable stopovers where they can refuel for the next stage of the journey.
A new study by the British Trust for Ornithology (BTO), in collaboration with scientists from several other research organisations, has revealed how one species, the highly migratory Arctic Skua, uses predetermined, mid-ocean meeting points while undertaking epic annual journeys.
Arctic Skuas are impressive birds. Their preferred way of feeding is by stealing from other seabirds, which they relentlessly harass with astonishing agility. Pursuing Puffins, terns and Kittiwakes, these pirates do not give up until their victim has relinquished its lunch. Sadly, like many other seabirds, these skuas are in serious decline. Arctic Skuas are the fastest declining seabird in the UK and are on the Birds of Conservation Concern Red List. Scientists from the BTO have been working to better understand the movements of these global wanderers to identify the continued threats the birds face.
