Log hazard ratios of the 2nd nest relatively to the 1st nest of the same female in the same breeding season.

Medians, quartiles and ranges are shown. Horizontal dashed line indicates log hazard ratio equal 0 (both nests similarly vulnerable to predation). Females whose first nest was depredated had the second nest relatively safer than females successful at their first breeding attempt (t test: t₈₃ = −2.71, p = 0.008; data from 2006 and 2009 were not included).
