New Locations And Range Extension Of Wintering Sandhill Cranes In Central Northern Mexico, Felipe Chavez-Ramirez Jan 2005

New Locations And Range Extension Of Wintering Sandhill Cranes In Central Northern Mexico, Felipe Chavez-Ramirez

Proceedings of the North American Crane Workshop

The overall distribution of wintering sandhill cranes in Mexico has been reported and summarized in several prior documents. However, most reports are associated with counts or surveys primarily conducted for wintering waterfowl. Recent (1999- 2002) reports compiled from local researchers show, that wintering sandhill cranes are distributed much more widely in northern Mexico than is currently reported in the literature. The new locations reported here are primarily in the eastern portion of the Mexican Altiplano, in the states of Coahuila and Nuevo Leon, and in the southern portions of the Chihuahuan Desert Region in Zacatecas and San Luis Potosi.

Migration Chronology, Routes, And Distribution Of Pacific Flyway Population Lesser Sandhill Cranes, Michael J. Petrula, Thomas C. Rothe Jan 2005

Migration Chronology, Routes, And Distribution Of Pacific Flyway Population Lesser Sandhill Cranes, Michael J. Petrula, Thomas C. Rothe

Proceedings of the North American Crane Workshop

Managers of migratory game birds require accurate information about bird movements to delineate populations, protect important habitats, and regulate harvest. Data describing movements of sandhill cranes (Grus canadensis) belonging to the Pacific Flyway Population (PFP) are lacking. We used satellite telemetry to monitor movements of PFP lesser sandhill cranes (Grus c. canadensis) captured in the upper Cook Inlet and Bristol Bay regions of Alaska. Satellite transmitters were deployed on 19 flightless young (colts) and 3 adults over 3-years (2000-2002). Chronology, routes, and stopover or staging areas were identified for fall and spring migration periods. On average, …
