Summary

We conducted a multi-year study (2010–2012) to investigate ecological factors that affect incubation behavior of nesting black-crowned night-herons Nycticorax nycticorax (hereinafter night-herons) on Alcatraz Island, California. This dataset includes incubation behavior data collected using video-monitoring techniques, as well as explanatory variables (temporal, weather, and nest site characteristics) from 2011-2012, and includes data for 126 video-monitored nest days across 64 nests (30 in 2011, and 34 in 2012). This dataset was used to model two different incubation behaviors (i.e. incubation constancy, and nest attendance), with respect to temporal, weather, and nest site characteristic variables, and specifically to investigate [...]

Purpose

The principle objective of this study was to explain variation in incubation behavior of night-herons by investigating effects of heterospecifics, climatic conditions, within-season temporal effects, and other ecological factors.
