Summary Of Mortality Among Captive Cranes At The International Crane Foundation: 2000-2020, Barry K. Hartup, Robert Phillips
Proceedings of the North American Crane Workshop
We reviewed mortalities of captive cranes at the International Crane Foundation (ICF) between 2000 and 2020 to provide broad insights into contemporary factors affecting the collection’s health and survival. Sixty-three deaths were documented in 13 of 15 crane species held in the ICF collection. The mean annual mortality during the study was 2.6% and the mean age (±SD) at death was 28.4 (±12.7) years. The overall total number of deaths of males and females was similar, but there was an association between sex and death of adult versus geriatric (>25 years) cranes (P < 0.01); males were more likely to die at geriatric age than females. Deaths were commonly associated with chronic health and management problems (n = 44, 79%) versus …

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.
