Ellis, David H., Gee, George F., Olsen, Glenn H. H., Hereford, Scott G., Nicolich, Jane M., Thomas, Nancy J., and Nagendran, Meenakshi. Minimum survival rates for Mississippi sandhill cranes: a comparison of hand-rearing and parent-rearing. In: Ellis, David H., ed., Proceedings of the Eighth North American Crane Workshop, 11–14 January 2000, Albuquerque, New Mexico (Seattle, Wash: North American Crane Working Group, 2001), pp. 80-84.
Hand-reared (56) and parent-reared (76) juvenile Mississippi sandhill cranes (Grus canadensis pulla) were produced at the Patuxent Wildlife Research Center (patuxent), Laurel, Maryland over a 4-year period (1989-92) and released at the Mississippi Sandhill Crane National Wildlife Refuge (Refuge), Gautier, Mississippi in a controlled experiment. Hand-reared survival rates proved higher than for parent-reared survival for each time category: 6 months, 86% versus 75%; 1 year, 77% versus 68%; 2 years, 66% versus 53%; 3 years, 55% versus 43%: partial data for fourth and fifth years were 57% versus 31 % and 48% versus 37%.
