Translocate individuals Bird Conservation

A review of two years (1987 and 1993) of survey data from 239 bird translocations in North America and Australasia (Wolf et al. 1996) showed 63% of 134 translocations in 1987 and 67% of 105 in 1993 resulted in the establishment of self-sustaining populations. Those translocations involving larger numbers of individuals, translocations of native game species (rather than threatened species), and translocations into the core (rather than the periphery) of the species’ historical range were most likely to establish self-sustaining populations.
