Survival And Sources Of Mortality In Florida Sandhill Crane Chicks – Hatching To Fledging, Stephen A. Nesbitt, Stephen T. Schwikert, Marilyn G. Spalding
Proceedings of the North American Crane Workshop
Forty-five pairs of Florida sandhill cranes (Grus canadensis pratensis) were monitored during the nesting seasons from 1996 through 1999. Thirty-eight chicks were produced from 25 successful nests. Twenty-one of these survived to fledging age. Predation was the source of most (81%) of the mortality for which a cause was determined. Mammals were the primary predator. Average age at time of mortality was 27.2 days for the 17 chicks lost.
