CBS02 Nests of Grasshopper Sparrows on Konza Prairie

This data set contains data describing Grasshopper Sparrow nests prior to 2017, and after that, additionally many Dickcissels, Eastern Meadowlarks, and other songbirds.. These nests were primarily found by rope dragging but also on surveys (see RI Survey Data Set), flushing birds during other activities, and via behavioral observations. We described nest contents and monitored nest fate via visits every 2-3 day and by placing an iButton placed in the center of the nest flush with the bottom of the nest cup and comparing temperature traces to a second iButton placed outside of the nest to determine the timing of nest failure and other metrics of incubation/brooding behavior. We compiled counts of partial egg loss, partial brood loss, and estimated causes of nest failure, comparing the timing of these events with KNZ-collected meteorological data to determine the temporal association between rainstorms and nest abandonment. Missing values in character fields denoted by NA, and in numeric fields -999.
