Flexible foraging patterns under different time constraints in tropical boobies (2004)
Journal Article
Lewis, S., Schreiber, E., Daunt, F., Schenk, G., Wanless, S., & Hamer, K. (2004). Flexible foraging patterns under different time constraints in tropical boobies. Animal Behaviour, 68(6), 1331-1337. https://doi.org/10.1016/j.anbehav.2004.04.007

The foraging behaviour of any animal is intricately linked to ecological constraints. Extrinsic factors, such as daylength, may limit the time available for foraging. Intrinsic factors, such as the coordination of mates at a nest site, may exacerbate... Read More about Flexible foraging patterns under different time constraints in tropical boobies.

Partitioning of diving effort in foraging trips of northern gannets (2004)
Journal Article
Lewis, S., Benvenuti, S., Daunt, F., Wanless, S., Dall'Antonia, L., Luschi, P., Elston, D. A., Hamer, K. C., & Sherratt, T. N. (2004). Partitioning of diving effort in foraging trips of northern gannets. Canadian Journal of Zoology, 82(12), 1910-1916. https://doi.org/10.1139/z05-005

Many species of seabirds are known to undertake foraging trips that vary in duration, lasting from a few hours up to several days. However, the important question of how individuals allocate their time during foraging trips of different durations has...

Local-scale variability in the diet of Black-legged Kittiwakes Rissa tridactyla (2004)
Journal Article
Bull, J., Wanless, S., Elston, D., Daunt, F., Lewis, S., & Harris, M. (2004). Local-scale variability in the diet of Black-legged Kittiwakes Rissa tridactyla. Ardea, 92(1), 43-52

The Black-legged Kittiwake Rissa tridactyla is a small gull that is widely distributed in the North Atlantic and Pacific. During the breeding season it feeds mainly on fish and, in the North Sea, the Lesser Sandeel Ammodytes marinus typically forms t...

Brood neglect and contingent foraging behavior in a pelagic seabird (2004)
Journal Article
Lewis, S., Hamer, K. C., Money, L., Griffiths, R., Wanless, S., & Sherratt, T. N. (2004). Brood neglect and contingent foraging behavior in a pelagic seabird. Behavioral Ecology and Sociobiology, 56(1), 81-88. https://doi.org/10.1007/s00265-004-0762-0

Among species where there is a risk to leaving offspring unattended, parents usually take alternating shifts guarding their young. However, they may occasionally exhibit brood neglect by leaving their offspring unattended at the nest. To investigate...
