This data set contains information (in two spreadsheets) from the monitoring of nests of Pacific, Yellow-billed and Red-throated loons at two 64 km2 sites in the National Petroleum Reserve-Alaska (NPR-A) during the summers of 2011-2014. We categorized each nest site by the physical aspects of the lake and proximity to other nesting loons. To determine nest fate (incubating, nest successful, nest failed), nests were revisited and inspected at least once a week. During each nest visit, we estimated embryo development (to predict hatch dates) by floating eggs. Nests were considered successful if one or more chicks hatched.
