Table 1 Models explaining variation in foraging activity (presence or absence from the core nesting area (10% kernel estimate)). Model selection based on Akaike Information Criterion scores (AIC). Results show the top ranked model included light level (measured as solar radiation (W/m2)) and held 100% of the weight. The analysis revealed that light level and its interaction with morph was the better explanatory variable when compared with either temperature, rainfall or time of day. AICc weight (W i ). Rain = average hourly rainfall, Temperature = average hourly temperature and Time = time (and its quadratic term). K denotes the number of parameters (K), change in AIC relative to the highest ranked model (ΔAIC), AIC weight (W i ). Morph = M, Light = L, Breeding stage = BS, Time = Ti, Temperature = Te, Rain = R.
