Osteoarthritis In The Pelvic Limb Of Captive Cranes, Barry K. Hartup, Savannah J. Lauer, Alyson R. Manthei
Proceedings of the North American Crane Workshop
We conducted an epidemiological study of osteoarthritis (OA) among the 15 captive crane species managed at the International Crane Foundation from 1973 to 2016. A retrospective review of 714 medical records found 37 cases of OA in 13 species of cranes and a corresponding period prevalence of OA of 5%. An analysis of the living captive crane flock as of 1 October 2016 (n = 115) found 12 active cases of OA (a point prevalence of 10%), and there was a statistical association between geriatric age classification (i.e., advanced age) and the presence of OA (P < 0.01). The mean age of cranes with OA was 14 years greater than cranes without the disease (P < 0.001). The prevalence estimates of OA from this review were somewhat lower than that from study of museum specimens, but this study similarly identified the tarsal joint as the predominant location of OA lesions in cranes.
Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup
Risk Factors Associated With Developmental Limb Abnormalities In Captive Whooping Cranes, Cristin Kelley, Barry K. Hartup
Proceedings of the North American Crane Workshop
This retrospective survey identifies potential risk factors for developmental limb abnormalities in whooping crane (Grus americana) chicks reared at the International Crane Foundation between 1990 and 2006. We summarized a series of biologicallyrelevant pre- and post-hatch variables from this population using in-house aviculture and veterinary records, and then compared them between chicks with and without developmental carpal, toe and leg deformities. Chi-square analysis revealed associations between 1) rearing style and each type of deformity, 2) egg source and carpal and toe deformities, and 3) the pre-existence of a toe deformity and carpal and leg deformities. Multivariate analyses using …

A Wasting Syndrome In Released Whooping Cranes In Florida Associated With Infectious Bursal Disease Titers, Marilyn G. Spalding, Holly S. Sellers, Barry K. Hartup, Glenn H. Olsen
Proceedings of the North American Crane Workshop
Whooping cranes (Grus americana) have been reintroduced into central Florida beginning in 1993 until the present. Bobcat predation of otherwise healthy cranes in good nutritional condition was the most common cause of mortality. However, release cohorts in the years 1997-1998 (14/22 died) and 2001-2002 (14/27 died, 5/27 clinical illness) experienced unusually high morbidity and mortality. Positive serum neutralizing titers for infectious bursal disease virus (IBDV) were identified following the 2001 event, and an epidemiological study of released birds and the captive source flocks was initiated. Serotype 1 (Lukert and Variant A) tests were mostly negative. Serotype 2 testing …
