From: Is multiple nest building an adequate strategy to cope with inter-species nest usurpation?
Nest level productivity (0–3 chicks per breeding attempt, N = 380 nests) depending on (a) the month of egg-laying (black bars on x-axis represent sample sizes); and, (b) geese interactions on nest level: no geese present, geese present, nest harassment and nest usurpation (‘nest g-score’ ranging from 0–3). P-values indicate significance in post-hoc comparisons. Figure based on predicted values of GLMMs, 95 % CIs in shaded grey or error bars; model details are given in Table 1
