This dataset contains the number of breeding pairs of bird species surveyed in all Cottonwood Lake Study Area wetlands.
The midcontinent population of sandhill cranes (Antigone canadensis) has historically been classified into three putative subspecies, but genetic analyses have identified only two genetically distinct subspecies. Previous studies have successfully used morphometrics in combination with an individual’s sex to differentiate subspecies of sandhill cranes that had been inferred based on breeding area, but no study has used a sample of genetically determined subspecies to discriminate and develop predictive models. These data were used to support an effort to develop a field-ready tool using common morphometric measurements without determination of an individual’s sex and linear discriminant analysis to classify genetically...
Wintering sandhill crane exposure to wind energy development in the central and southern Great Plains, USA datasets
Numerous wind energy projects have been constructed in the central and southern Great Plains, USA, the main wintering area for midcontinent Sandhill Cranes (Grus canadensis). We assessed exposure of wintering Sandhill Cranes to the current distribution of wind towers in the central and southern Great Plains by estimating overlap using location data from platform transmitting terminals (PTT) collected during winters 1998–2004. Because 90% of wind towers in the region were installed 2004–2013, comparing an established distribution of wind towers (as of January 2014) with pre-construction crane (1998-2004) distribution provides an initial assessment of the midcontinent population’s exposure. Distributions of cranes...
Midcontinent sandhill cranes (Antigone canadensis) are the most abundant management population of cranes in the world and have a broad breeding range. Four breeding segments of midcontinent sandhill cranes have been designated based on spatial and temporal distributions throughout the year, including Western Alaska–Siberia (WA–S), Northern Canada–Nunavut (NC–N), West-central Canada–Interior Alaska (WC–A) and East-central Canada–Minnesota (EC–M). WA–S and NC–N cranes primarily are composed of the lesser sandhill crane (A. c. canadensis) subspecies that breeds in the arctic, whereas WC–A and EC–M cranes are composed primarily of greater sandhill cranes (A. c. tabida), birds which breeds in northern parts of temperate...
