  1. Translocate gamebirds

    A replicated study of 42 adult and 35 immature ruffed grouse Bonasa umbellus translocated from Illinois, USA, to Creek State Forest, Missouri, in autumn 1986 (Kurzejeski & Root 1988) found that 25% of translocated birds survived until May 1987.  A maximum of eight of 37 females survived until the breeding season. Mortality rates were highest in the post-release period, with 15 grouse dying within seven days of release. Eighty-six percent of mortalities were attributed to avian or mammalian predation. Birds injured in transit did not have a lower survival rate than those without visible injury at the time of release.
