Data on the location, identity, and reproductive index (Vickery et al. 1992) of Grasshopper Sparrows prior to 2017, and after that, additionally many Dickcissels, Eastern Meadowlarks, Brown-headed Cowbirds and other songbirds within 10-ha plots on multiple watersheds units on Konza and on two adjoining units on the Rannells Preserve. Each plot was surveyed every ~7-10 days. These surveys documented individual sparrow, Dickcissel, and Eastern Meadowlark locations, and are used to calculate dispersal distances and territory densities and movements. Missing values in character fields denoted by NA, and in numeric fields, either -999 or -9.
Location of Sampling Stations: 14 watershed units on Konza and 2 adjoining units on Rannell’s Preserve.Frequency of Sampling: Every ~7-10 days.Variable Measured: Date, location weather, number of territorial males.
