Release captive-bred individuals into the wild to restore or augment wild populations of songbirds Bird Conservation

A replicated study (Tweed et al. 2003) reviewing the same programme as in Kuehler et al. 2000 found that all 14 captive-bred puaiohi Myadestes palmeri released survived for at least 56 days after release. Six of the birds (43%) established breeding territories and two of the remaining females formed pairs with local males. The authors note that repopulating specific areas may require multiple releases because of the 57% dispersal out of the release area.
