APPENDIX FIGURE 5.

Using the subset of nests with precise age estimates (nests that were observed during egg laying or that hatched; n = 571), observations were primarily distributed between incubation (43%) and nestling stages (54%), with few observations during egg laying (2%) or when nests were >24 days old (0.04%). Labeled bars at the top of the figure delineate the breeding stages for a typical nest, though we note that this is an approximation due to the 2- to 5-day visit schedule and individual variation.
