Long‐term within‐season changes in the diet of Common Guillemot ( Uria aalge) chicks at a North Sea colony: implications for dietary monitoring
Over four decades (1982–2019) there were pronounced within‐season changes in the proportion of a key prey species (Lesser Sandeel Ammodytes marinus ) in Common Guillemot Uria aalge chick diet. As Sandeels became scarcer their occurrence was largely confined to the early part of the chick period. Con...
