Diet of Gulls

Research into the effects of foraging strategies in a generalist species

All generalists are equal, but some are more equal than others

Even if a species is known as a generalist, this does not necessarily entail that all individuals of that species have the same diet. Some may be very selective in the choice of food, others may have a more varied diet. Although such individual differences occur in many species, the consequences of differences in foraging strategy are still poorly understood.

Gulls (Larus species) are an example of such a generalist in which individuals may differ in their choice of food.

Foraging strategies of herring gulls

In this project I investigate the consequences of foraging strategies of herring gulls (Larus argentatus) that breed on Texel. I examine whether differences in foraging strategies among gulls are reflected in chick growth, breeding success and energy budgets of the parents. I also investigate whether gulls with different diets respond differently to changes in their environment.
