We conducted a multi-year study (2010–2012) to investigate diel patterns of specific incubation behaviors of nesting black-crowned night-herons Nycticorax nycticorax (hereinafter night-herons) on Alcatraz Island, California. This dataset includes hourly percentages of specific incubation behaviors (i.e. inactivity, vigilance, preening, and nest maintenance) from ~230 video-monitored nest days across 83 nests (18 in 2010, 30 in 2011, and 35 in 2012).

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...

This dataset includes incubation behavior data collected using video-monitoring techniques, as well as explanatory variables (temporal, weather, and nest site characteristics) from all three years of the study (2010-2012), and includes data for 211 video-monitored nest days across 81 nests (17 in 2010, 30 in 2011, and 34 in 2012). This dataset was used to model two different incubation behaviors (i.e. incubation constancy (INCCONST), and nest attendance (ATTEND)), with respect to temporal,...

This dataset is a 30-meter resolution national-scale raster of estimated subsurface tile drainage extent based on early 1990s county areas of subsurface tile drains and geospatial datasets of cropland and poorly drained soil. Specifically, it was developed using 1) county-level acres of subsurface tile drain extents from Sugg (2007); 2) the extent of cultivated cropland from the National Land Cover Database (NLCD) 2011; 3) the extent of poorly drained soil from the State Soil Geographic (STATSGO) database Version 2; 4) the extent of federally-owned land, and 5) county administrative boundaries. Sugg's (2007) area of subsurface tile drains within each county was evenly allocated to potentially drained land -- cropland...
