Factors affecting the probability of GPS tracked lesser black-backed gulls to forage on land or at sea for two statistical models: of all years (2011–2013) for incubation through to late chick-rearing (a), and for 2012–2013 with the addition of the pre-laying period b. Main effects terms for models showing the factors affecting the probability of GPS tracked lesser black-backed gulls performing terrestrial rather than marine foraging trips. Coefficients and 95 % confidence intervals (Wald estimates) are shown for the standardized models allowing direct comparison of effects between variables. Coefficients are compared to the model reference level: incubation stage 2011 (a), pre-laying stage 2012 (b)
