Which combination of release techniques and ages minimizes post-release dispersal during Oriental Stork reintroduction?

Many reintroduction attempts have encountered difficulties with long-distance dispersal of the released animals. In previous studies, release techniques and ages of the released individuals have been tested separately to examine their influence on post-release dispersal, with varied results. Dispers...

description Many reintroduction attempts have encountered difficulties with long-distance dispersal of the released animals. In previous studies, release techniques and ages of the released individuals have been tested separately to examine their influence on post-release dispersal, with varied results. Dispersal patterns may be determined by a combination of release techniques and individual characteristics (age or rearing history). To reintroduce the Oriental Stork ( Ciconia boyciana ) to Japan, we released 1–7-year-old birds using soft and hard release techniques. The effects of different combinations of release techniques and ages or rearing histories on Oriental Stork dispersal distance and area within the first year after release were documented using global positioning system tracking data. Following soft and hard releases, some 1-year-old released birds became widely dispersed. However, all 1–3-year-old birds stayed in close proximity to the release sites. Therefore, hard-release techniques may be less problematic for Oriental Stork reintroduction if 1–3-year-old birds are selected for release. Soft-released first-year birds that had larger core areas and longer dispersal distances were not transported and trained, had only family members as their cage mates, and were reared by foster parents until fledging. Therefore, rearing histories could be an important factor in determining dispersal area and distance. To prevent the long-distance dispersal of species with the same ecological characteristics as the Oriental Stork (carnivorous, territorial, unattracted to conspecifics), we suggest hard-releasing 1–3-year-old birds.
