ABSTRACT Translocation outcomes in connected habitats are often uncertain, as individuals dispersing outside managed areas exposed to threats. Post‐release monitoring can reduce uncertainty by revealing how dispersal and habitat selection influences establishment population growth which inform future translocations. We undertook post‐release identify patterns following a translocation of toutouwai (North Island robin, Petroica longipes ) large, contiguous forest habitat. aimed estimate survival, dispersal, territory management decisions release site selection. created species distribution models using data differences during the phases. Toutouwai dispersed across 1312 ha but established territories within only 113 1 km from location. Site fidelity was higher than predicted, there no difference or demographic groups. Critically, high suggested that extent sufficient protect individuals. Habitat preferences were stronger associated with lower slopes, water deficit proximity reservoirs. Species modelling allowed for predictions high‐quality core where more likely, resulting targeted improve growth. Our results show initial may be much larger alone, need support successful establishment. demonstrate effective quality guide actions translocations outcomes.
