Table 1 Summary statistics for GLMMs to look at temporal and weather influences on the probability of lesser black-backed gulls (n = 19) to forage on terrestrial- over marine- habitat during foraging trips (n = 1024). All models include individual gull ID as a random effect. Akaike information criterion adjusted for small sample sizes (AICc), change in AICc relative to the best-fit model (18) and marginal R2 (R2m) and conditional R2 (R2c) values are presented
