We thank the USGS Northern Prairie Wildlife Research Center and the University of Nebraska State Museum for collecting and providing samples, David A. Brandt for his role in obtaining blood samples and taking morphological measurements, Sarah Lee, University of Western Ontario Zoology Department (London, Ontario), for determining the gender of collected cranes, and Douglas H. Johnson, NPWRC, for running discriminant analyses to determine subspecies based upon morphology. This project was completed with partial funding from a HHMI research fellowship from Nebraska Wesleyan University to JP and by the USGS Northern Prairie Wildlife Research Center. David B. Taylor, Richard D. Peterson II, Robert R. Cox Jr., David E. Sharp, and two anonymous reviewers provided thoughtful suggestions to improve the presentation of this paper. This is paper number 13126 of the Journal Series, Nebraska Agricultural Research Division.

N2 - Three subspecies of sandhill crane (Grus canadensis) are recognized in the Midcontinental population, the lesser (Grus c. canadensis), Canadian (G. c. rowani), and greater (G. c. tabida). Blood samples collected on the population's primary spring staging area in Nebraska, U.S.A., were used to resolve the genetic relationship among these subspecies. Phylogenetic analysis of 27 G. canadensis, by DNA sequencing of a 675 bp region of the mtDNA, supports the subspecies designations of G. c. canadensis and G. c. tabida. G. c. rowani individuals were intermediate with each of the other two subspecies. Genetic divergence ranged from 6.5 to 14.5% between G. c. canadensis and G. c. tabida, 0.5 to 6.6% within G. c. canadensis, and 0.1 to 6.0% within G. c. tabida. Sufficient DNA for analysis was obtained from shed feathers indicating a source of genetic material that does not require the capture or sacrifice of the birds. Other genetic markers and methods, including satellite telemetry, are required for obtaining detailed information on crane distributions as needed to establish effective management units for the MCP.
