Predicted probability of digging during a 30-s acceleration burst (burst interval 4.5 min) as a function of A nesting goose density (a proxy for goose nest density) and goose reproduction period (incubation in blue, brooding in orange), and B sex and reproductive status (reproductive in blue, non-reproductive in orange). Nesting goose density was centered and standardised in the model, then back-transformed before plotting. Model reference values are fox sex = male, fox reproductive status = reproductive, period = incubation and nesting goose density = average
