- Abstract
- Natal dispersal and habitat selection of hazel grouse Bonasa bonasia juveniles were assessed by radio tracking in a temperate forest of South Korea during June 2003-November 2006. The birds used in the dispersal analysis (n = 43), 88% of birds dispersed. The average dispersal of hazel grouse from the natal area was 2231 +/- 494 m (mean +/- SD); range 134-6267 m. There were no significant differences in dispersal rate and distance between sexes. Hazel grouse' habitat use differed from random use of available natal dispersals. In this natal dispersal scale of habitat selection, natural deciduous forest ranked highest, followed by mixed forest, coniferous plantation, deciduous plantation and others (rock and bare lands). We found that in general, the hazel grouse is an active disperser. Knowledge of aspects of habitat use that are relevant to dispersal may provide a better assessment of the fitness effects of dispersal in proximate and ultimate terms. (C) 2009 Elsevier B.V.
