Reproduction, Dispersal, and Survivorship of Ruffed Grouse Reintroduced into Arkansas

Reproductive success of 94 ruffed grouse (Bonasa umbellus) reintroduced into northern Arkansas during September and October 1984 was apparently low. Four broods were found during 2 reproductive seasons after release. Dispersal of all located male ruffed grouse was limited to a 1.6 km radius of the initial release site. Brood sightings in an area 2.4 to 2.8 km northeast of the initial release site were direct evidence of female dispersal. Survivorship of male grouse up to the first courtship drumming period was at least 25%.
