Table 2 Inter-nest distance summary statistics. The observed (O) values of statistics and expected (E) values based on 1,500 simulated inter-nest distance distributions under our base null model. Bolded values of expected variances indicate that the observed variance was contained in the distribution of the 1,500 simulated variances (Ω>0.05). Proportion indicates the frequency of repeat breeders that spawned at the same location in consecutive years
