A week on from #StormAmy 🌬️ data from our tagged Whooper Swans show both storm assistance & storm displacement. Some birds made rapid migrations, others battled the elements – some out at sea for 55 hrs! As North Atlantic storms grow more frequent, understanding their impact is vital. 🦢 #Ornithology
