3.5 Mya) of Idaho (Feduccia, 1967).

Acanthocephalans have caused severe morbidity and mortality in captive-reared Whooping Crane chicks, including perforation of the intestines with resulting severe peritonitis (Olsen, 2009; Olsen et al., 1996).

This pattern appears to be replicated in the reintroduced EMP, where birds center on their release areas during the summer. 11.2). Older birds are largely concentrated in the center of the range, while younger birds exhibit a wider spread in summer locations. Whooping Cranes have been reintroduced to alternative habitats during summer in Wisconsin to identify the precise type of wetlands necessary to produce sustainable reproduction. In the last month Whooping Cranes have started moving around a bit but haven’t yet started migrating. The total is one of the lowest in years. From this tiny group of birds, just 16 individuals emerged as the founders of the recovering population that numbers more than 800 today. 10 things you may not know about Whooping Cranes, Learn more about Friends of the Wild Whoopers. I then was a Chapman Postdoctoral Fellow in Ornithology at the American Museum of Natural History in New York City.
“It appears that conditions at the park were better than last year,” according to the Friends group. According to mitogenomic analyses, it is the sister group of a clade that includes the Eurasian, Hooded, and Black-necked cranes, from which it diverged some 3.7–3.9 Mya in the Pliocene. The second era, continuing to the present, has been characterized by development of information about cranes through scientific study, conservation efforts of governmental and nongovernmental organizations, protection of the species under the Endangered Species Act in the United States and the Species at Risk Act in Canada, habitat protection, and reintroduction of new populations of Whooping Cranes. The results are further used to determine if sufficient habitats are currently, and will be, available to support various population targets identified in the current recovery plan. This procedure was carried out by Operation Migration. All surviving fostered chicks and released juveniles remained in the Florida Sandhill Crane range and did not migrate, providing evidence that migration is a learned behavior. In most of these cases, parasitism was an incidental finding (Spalding et al., 1996), with most mortalities due to bobcat predation and 24 of 27 birds in very good body condition.

Whooping cranes nest on the ground, and produce a clutch of 1-2 olive-coloured eggs per year. Fish and Wildlife Service, 2007). In June–September, the mean distance of an individual to the protected area (either Necedah NWR, Horicon NWR, or White River Marsh SWA) where it was released is 36 km after age 1 (n = 619, SE = 4 km), with the majority of birds remaining within the same protected area where they were released. At the end of this project five surviving Greater Sandhill Cranes were recaptured and taken into captivity, and others (four fostered chicks and eight released birds) were not captured and left in the wild.

Whooping Cranes were initially reintroduced at Necedah NWR, with recent ultralight releases moved to White River Marsh State Wildlife Area (SWA) (2011–present) and direct autumn releases (where juveniles are released with no ultralight training) at Necedah NWR (2005–10) and Horicon NWR (2011–present); all three protected areas are in the same region of central Wisconsin (Fig.
