Spring Migratory Habits And Breeding Distribution Of Lesser Sandhill Cranes That Winter In West-Central New Mexico And Arizona, Gary L. Krapu, David A. Brandt
Spring Migratory Habits And Breeding Distribution Of Lesser Sandhill Cranes That Winter In West-Central New Mexico And Arizona, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
Little information exists on the spring migratory habits and breeding distribution of lesser sandhill cranes (Grus canadensis canadensis) that winter in west-central New Mexico and southeastern Arizona. To address this question, we captured and attached a total of 6 Platform Transmitting Terminals (PTT) to adult lesser sandhill cranes at 2 sites each in west-central New Mexico and southeastern Arizona during December 2001 and monitored the birds’ movements to arrival on their arctic breeding grounds. After departing from their wintering grounds, 2 of the cranes stopped at Monte Vista NWR in south-central Colorado where they stayed for 17 and …
Migration Routes, Staging Areas, And Wintering Grounds Of Sandhill Cranes That Breed In Siberia, Gary L. Krapu, David A. Brandt
Migration Routes, Staging Areas, And Wintering Grounds Of Sandhill Cranes That Breed In Siberia, Gary L. Krapu, David A. Brandt
Proceedings of the North American Crane Workshop
We determined breeding sites, migration routes, spring and fall staging areas, and wintering grounds for sandhill cranes (Grus canadensis) from the midcontinent population that nest in Siberia. Our results are from 30 PTT-marked individuals captured and marked along the Platte and North Platte Rivers in Nebraska. Findings indicate the species breeds across a vast area of northeastern Siberia extending at least 1500 km west from near the Bering Strait to the Kolymskaya Plains with most breeding confined to within 75 km of the coast. We describe when PTT-tagged cranes arrived at breeding sites in Siberia, duration of stay, …
A Comparison Of Behavior For Two Cohorts Of Captive-Reared Greater Sandhill Cranes Released In Northern Arizona, Daniel P. Mummert, Carol L. Chambers, David H. Ellis
A Comparison Of Behavior For Two Cohorts Of Captive-Reared Greater Sandhill Cranes Released In Northern Arizona, Daniel P. Mummert, Carol L. Chambers, David H. Ellis
Proceedings of the North American Crane Workshop
To determine how the behavior of greater sandhill cranes (Grus canadensis tabida) changes according to time of year, time of day, and number of days after release, we observed the activities of 2 groups of captive-reared greater sandhill cranes at Mormon Lake, northern Arizona. The behaviors we compared were alert, loafing, sleeping, foraging, preening, locomotion, and other. We found costume-reared subadult greater sandhill cranes that were established at the study site for a year spent more time foraging and being alert towards predators than parent -reared juvenile greater sandhill cranes that were recently released from captivity. We also …
