Seasonal differences in at-sea activity of seabirds underline high energetic demands during the breeding period
International audience We assessed seasonal differences in at-sea activity of Lesser Black-backed Gulls , Black-legged Kittiwakes and Common Guillemots in the south-eastern North Sea. The three species correspond to different ecological groups, with Lesser Black-backed Gulls representing omnivorous...
