Sage Thrasher detection data


Point transect data collected in central Wyoming from 120 points surveyed for Sage Thrashers by the Wyoming Cooperative Fish & Wildlife Research Unit in 2013. See package vignettes for tutorials of the basic analysis.


A data.frame containing 193 rows and 3 columns. Each row represents a detected group of thrashers. Column descriptions:

  1. siteID: Factor (120 levels), the site or point where the detection was made.

  2. groupsize: Number, the number of individuals within the detected group.

  3. dist: Number, the radial distance (m) from the transect to the detected group. This is the distance used in analysis.


The Sage Thrasher data are a subset of the data collected by Jason Carlisle and various field technicians for his Ph.D. from the Department of Ecology, University of Wyoming, in 2017. This portion of Jason's work was funded by the Wyoming Game and Fish Department through agreements with the University of Wyoming's Cooperative Fish & Wildlife Research Unit (2012).
