Does ‘acoustic anchoring’ reduce post-translocation dispersal of North Island robins?
(CSIRO Publishing, 2011)Context: Animal translocations are an important conservation tool; however, post-release dispersal can hinder successful population establishment. Playback of conspecific song attracts dispersing individuals in some species, ... -
Evolutionary Significance and Conservation Implications of Vocal Dialects in North Island Kōkako (Callaeas wilsoni)
(University of Waikato, 2012)Kōkako (Callaeas wilsoni) are endangered, duetting songbirds endemic to New Zealand and are confined to a small number of managed mainland reserves and offshore islands. Each fragmented population exhibits distinctive vocal ... -
Factors affecting post-release dispersal, mortality, and territory settlement of endangered kokako translocated from two distinct song neighborhoods
(Elsevier, 2012)Animal translocation success rate is generally low, with the causes of failure poorly understood without comprehensive and protracted monitoring. Here we examine the outcome of a translocation of endangered North Island ... -
Local-foreign dialect discrimination and responses to mixed-dialect duets in the North Island kokako
(Oxford University Press, 2013)Social discrimination based on geographic variation in territorial signals is taxonomically widespread—most studies have found stronger reactions to local than to foreign signals. In birds with male-only song, this ... -
Post-translocation assortative pairing and social implications for the conservation of an endangered songbird
(Wiley, 2013)Animals translocated for conservation purposes may be sourced from multiple locations which may exhibit inter-site variability in reproductive behaviours. The influence that these differences may have on the propensity of ...
