Ocean climate and egg investment in the black-legged kittiwake Rissa tridactyla
Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may thus vary in response to food availability prior to egg laying. We investigated...

Birds allocate substantial resources to their eggs during the laying period, resources also needed for other concurrent costly processes such as mate acquisition, nest building and site defence. Egg and clutch sizes may thus vary in response to food availability prior to egg laying.

Considerable interannual variation was evident in both egg and clutch sizes, but no temporal trends were observed.
