Table 2 Summary statistics for GLMMs to look at temporal and weather influences on the probability of lesser black-backed gulls (n = 14) to forage on terrestrial- over marine- habitat during foraging trips (n = 959), including the pre-laying period (April 30 - May 19) in 2012 and 2013. 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 (7) and marginal R2 (R2m) and conditional R2 (R2c) values are presented
