Changes In Winter Whooping Crane Territories And Range 1950-2006, Thomas V. Stehn, Felipe Prieto
Changes In Winter Whooping Crane Territories And Range 1950-2006, Thomas V. Stehn, Felipe Prieto
Proceedings of the North American Crane Workshop
The whooping crane (Grus americana) winters on the Texas coast primarily in salt marsh habitat. The location of adult whooping crane winter territories during 9 winters between 1950 and 2006 was derived from aerial census data digitized onto infrared photos using GIS software. Range expansion, including changes in distribution and size of winter territories, was analyzed over a 57-year period as flock size increased by 765%. Crane pairs have opted to establish territories in or close to the traditional winter area rather than moving long distances along the coast. This distribution seems based on the preference of the …

John James Audubon, a well-known bird expert and nature enthusiast, described wild turkeys as birds of great beauty. The history and origin of wild turkeys is uncertain, yet many share Audubon’s sentiment that the wild turkey is “one of the most interesting of the birds indigenous to the United States of America.” Today, wild turkeys can be found throughout the nation. Following the selection of the bald eagle as the American symbol, Benjamin Franklin remarked that the turkey was more “respectable”, and a “true original native”.

The chicken is the world’s most numerous domesticated bird, with over 52 billion farmed worldwide in 2008, rivaling the dog as the most ubiquitous domestic animal globally. These birds have fascinated scholars and researchers since the dawn of Western civilization, and recent studies are beginning to reveal the depths of their complexity and cognitive ability. According to Andrew F. Fraser, professor of veterinary surgery at Memorial University of Newfoundland, and Donald M. Broom, professor of animal welfare at University of Cambridge: “Those who have studied the behaviour of the domestic fowl in detail…, especially those who have looked at feral …

Migration Patterns And Movements Of Sandhill Cranes Wintering In Central And Southwestern Louisiana, Sammy L. King, Aaron R. Pierce, Kent R. Hersey, Nicholas Winstead
Proceedings of the North American Crane Workshop
In this study we trapped wintering sandhill cranes (Grus canadensis) in Louisiana and fitted them with satellite transmitters to determine their migration routes. Four of the 6 sandhill cranes with validated locations and a terminus point used the Central Flyway for spring migration; 2 of these 4 (the only 2 for which we have data) also used the Central Flyway for fall migration. Two of the 6 birds used the Mississippi Flyway for spring migration. The results of this study suggest that reintroduced whooping cranes (G. americana) that intermix and migrate with sandhill cranes that winter …
