Mahan, Thomas A., and Brenda S. Simmers. "Social Preference of Four Cross-Foster Reared Sandhill Cranes.", In: Stahlecker D. W., ed. 1992. Proceedings of the Sixth North American Crane Workshop, Oct. 3-5, 1991, Regina, Sask. (Grand Island, NE.: North American Crane Working Group, 1992), 114-19.
Four greater sandhill cranes (Grus canadensis tabida) were hatched and reared individually by 4 non-sandhill crane pairs: 2 by white-naped crane (G. vipio) pairs, 1 by a Siberian crane (G. leucogeranus) pair, and 1 by a red-crowned crane (G. japonensis) pair. After 1 year the sandhill cranes (2 male and 2 female) were placed in enclosed pens adjacent to an oppositesexed, same-age bird of the foster species on 1 side and an opposite-sexed, same-age conspecific on the other side. Data were collected throughout 1 year and included proximity between test and choice birds and behaviors displayed. Each test bird socialized with the foster species more than with a conspecific. This preference was much more apparent for females than for males.
