First-year Movements of Yellow-legged Gull (Larus michahellis lusitanius) from the Southeastern Bay of Biscay.

The article discusses a study on the movements of first-year Yellow-legged Gulls or Larus michahellis lusitanius from the southeastern Bay of Biscay. It cites the use of darvic rings which allow researchers to conduct a more detailed analyses on movements of large gulls with consideration on the maximum distance where each individual was sighted. It suggests that a precise data on distribution of food availability can lead to a better understanding of the seasonal geographic distribution patterns of Yellow-legged Gulls in the southeastern Bay of Biscay.
