Prey ingestion rates revealed by back-mounted accelerometers in Eurasian spoonbills

Table 2 Model selection of seasonal and annual variation in prey ingestion rates, estimated by the RF model applied to 0.4 s segments of 20 Hz acceleration data

Season is modelled as a quadratic effect of day of the year (yday): β₀ + β₁·yday + β₂·yday². For the model season * year, the three β-parameters are estimated separately for each year. All models include a random intercept (random variation around β₀), and for the models with seasonal effects also random slopes (random variation around β₁ and β₂), with individual as random effect
