Results of a mixed model in which the effect of relative pink-footed goose numbers was estimated in relation to different time periods (Phase 1–6, see Fig. 1), scaring activity by farmers (0 = no scaring, 1 = moderate scaring, 2 = intensive scaring) and barnacle goose numbers relative to pink-footed goose numbers.
