Can redirected aggression explain interspecific attacks by Australian magpies on other birds?
(Brill, 2007)Attacks by participants of conflicts against a third party are referred to as redirected aggression. Usually the third party is a conspecific — few documented cases of redirected aggression against other species exist. The ... -
Comparing plasma and faecal measures of steroid hormones in Adelie penguins Pygoscelis adeliae
(Springer, 2010)Physiological measurements of both stress and sex hormones are often used to estimate the consequences of natural or human-induced change in ecological studies of various animals. Different methods of hormone measurement ... -
Conservation implications of song divergence between source and translocated populations of the North Island Kōkako
(Wiley, 2013)1. Translocation of individuals from healthy source populations to newly colonize or recolonize suitable habitat is a vital tool for the conservation of a species. Demographic, genetic and landscape factors, but also ... -
Converting predation cues into conservation tools: The effect of light on mouse foraging behaviour
(Public Library of Science, 2016)Prey face a conflict between acquiring energy and avoiding predators and use both direct and indirect cues to assess predation risk. Illumination, an indirect cue, influences nocturnal rodent foraging behaviour. New Zealand ... -
Do heterospecific size and demeanour influence visitation behaviour of birds at urban foraging patches?
(Springer, 2011)We compared the feeding behaviour of garden birds in the presence of four heterospecific decoy species at suburban feeding stations to assess the relative importance of body size (large vs. small) and demeanour (high vs. ...

Bird repellents for pest control baits
(The University of Waikato, 2003)Poisonous baits are successfully deployed over large areas of New Zealand to control mammalian pests such as brushtail possums (Trichosurus vulpecula) and rats (Rattus spp.). While poison-based control leads to positive ... -
Song and Territorial Behaviour of Male-Male and Male-Female Pairs of the North Island Kokako (Callaeas cinerea wilsoni)
(The University of Waikato, 1998)Male-male pairing has been previously described for captive individuals of two duetting passerines. The sexually monomorphic North Island kokako (Callaeas cinerea wilsoni) is an endangered forest bird which is declining ... -
Behavioural interactions and reasons for aggression between Australian magpies (Gymnorhina tibicen) and other birds in New Zealand
(The University of Waikato, 2006)The Australian magpie (Gymnorhina tibicen; magpie hereafter) was introduced to New Zealand from 1864 in an attempt to help control pest invertebrates in pasture. Since the introductions, magpie populations have gradually ... -
Disbudding of dairy goat kids: Refining protocols to reduce or eliminate pain
(The University of Waikato, 2018)The aim of this thesis was to investigate potential improvements for disbudding dairy goat kids to eliminate or reduce pain. Behavioural and physiological measures were used to evaluate: (1) pain associated with four ... -
Sequencing the New Zealand dawn chorus: can song playback alter the timing of song initiation?
(University of Waikato, 2017)The dawn chorus of songbirds is a behavioural phenomenon occurring prior to sunrise; birds of many different species sing simultaneously at rapid rates. Avian physiology, social behaviours and local environment all influence ...
