| a retrospective survey into the presence of plasmodium spp. and toxoplasma gondii in archived tissue samples from new zealand raptors: new zealand falcons (falco novaeseelandiae), australasian harriers (circus approximans) and moreporks (ninox novaeseelandiae). | human colonisation of new zealand has resulted in the introduction of emerging diseases, such as avian malaria and toxoplasmosis, which arrived with their exotic avian and mammalian hosts. plasmodium spp. and toxoplasma gondii have a wide host range, and several species of endemic new zealand birds have developed a fatal disease following infection with either pathogen. however, no reports of either toxoplasmosis or avian malaria in new zealand raptors, namely, the new zealand falcons (falco nov ... | 2017 | 28660290 |

| the role of lead in a syndrome of clenched claw paralysis and leg paresis in swamp harriers (circus approximans). | we investigated the hypothesis that lead poisoning was the cause of the clinical syndrome of clenched feet paralysis and leg paresis in wild raptors. swamp harriers (circus approximans) are one of three extant native raptor species in new zealand. harriers with the syndrome were found to have statistically significantly higher blood lead concentrations than those without clenched feet (t-test; t=-4.06, df=5, p=0.01). however, elevated blood lead concentrations were also present in 60% of wild ha ... | 2011 | 22102661 |
| the scavenging behaviour of ferrets (mustela furo), feral cats (felis domesticus), possums (trichosurus vulpecula), hedgehogs (erinaceus europaeus) and harrier hawks (circus approximans) on pastoral farmland in new zealand: implications for bovine tuberculosis transmission. | to identify species that scavenge carcasses in pastoral habitats in new zealand; to determine whether there were interspecific or intraspecific differences in scavenging behaviour and; to document any interspecific or intraspecific interactions occurring at carcasses. | 2000 | 16032148 |
| assessment of risks of brodifacoum to non-target birds and mammals in new zealand. | the risks to non-target birds and other wildlife from the use of vertebrate pesticides, including anticoagulant rodenticides, are determined to a significant extent by species' intrinsic susceptibility, and the toxicokinetics of the compounds used. brodifacoum is highly toxic to birds and mammals. the acute toxicity of brodifacoum to birds in new zealand varies from <1 mg/kg in pukeko (porphyrio p. melanotus), the native swamp hen, to >20 mg/kg in the paradise shelduck (tadorna variegata). like ... | 2002 | 11898799 |
