Predicting release success of captive-reared loggerhead shrikes (Lanius ludovicianus) using pre-release behavior

Abstract 10.1002/zoo.20067.abs We assessed whether behavioral markers could be used to evaluate pair compatibility and predict pair bond success of captive-reared San Clemente loggerhead shrikes (Lanius ludovicianus mearnsi) released into the wild. Potential breeding pairs of shrikes were introduced at the Zoological Society of San Diego’s captive-breeding facility and then moved to release cages located […]

Captive-Reared Burrowing Owls Show Higher Site-Affinity, Survival, and Reproductive Performance When Reintroduced Using a Soft-Release

A remaining challenge for animal reintroductions is how best to aid individuals transitioning from captivity into the wild. We tested two techniques – ‘soft’ vs. ‘hard’ release – in a 7-year study on endangered Western burrowingowls (Athene cunicularia hypugaea) in British Columbia, Canada. Traditionally, captive-reared yearling adults were released into the wild, as pairs, directly […]
