Female gonadal hormones and reproductive behaviors as key determinants of successful reproductive output of breeding whooping cranes (Grus americana)

Cranes of the World: Whooping Crane (Grus americana)

Haemosporida prevalence and diversity are similar in endangered wild whooping cranes (Grus americana) and sympatric sandhill cranes (Grus canadensis)

The population growth of endangered whooping cranes (Grus americana) is not consistent with species recovery goals, and the impact of parasite infection on whooping crane populations is largely unknown. Disease ecology and epidemiology research of endangered species is often hindered by limited ability to conduct invasive sampling on the target taxa. Accordingly, we hypothesized that sandhill c...

be devoted to a more detailed analysis of additional serum samples from these and other wolf populations in the state. This study was supported by the U.S.D.I. Fish and Wildlife Service, the Mardag Foundation, the U.S.D.A. North Central Forest Experiment Station, the University of Minnesota College of Veterinary Medicine, and the Veterans Administration Medical Center. The cooperation of field ...

Aerial Survey Techniques for Breeding Whooping Cranes

Since the discovery of nesting whooping cranes in Wood Buffalo National Park, the Canadian Wildlife Service has conducted aerial surveys to monitor the population. Aerial survey techniques have varied over the years; however, they have generally followed the techniques used by the author since 1991. The technique involves flying a combination of circular flights and transects over known nesting...

Reproductive Health and Performance of the Florida Flock of Introduced Whooping Cranes

We retrospectively examined the reproductive parameters of 122 breeding-age whooping cranes (Grus americana) in a reintroduced flock in central Florida from 1992 to 2007. The flock performed poorly when compared with an existing wild flock for all reproductive parameters when controlled for age. Pairs first formed in 1995, nested in 1999, and the first chick fledged in 2002. By 2007, 19 of 63 c...
