Control of a stoat (Mustela erminea) population irruption to enhance mohua (yellowhead) (Mohoua ochrocephala) breeding success in New Zealand |
“Even when we found a failed nest, we could not always tell if predation caused the loss, as stoats leave little sign of having killed mohua.” |

Evidence of Possums as Predators of Native Animals. In The Brushtail Possum Biology, Impact and Management of an Introduced Marsupial |
“In subsequent captive possum feeding trials, K. Walker and G. Elliot (Department of Conservation, Nelson, pers. Comm.) found four of six possums readily ate the much larger Powelliphanta land snails, which also had characteristic holes and scratches on the shell (Fig. 11.2). Since then possum-damaged shells have been found in many snail populations in the Marlborough Sounds, in the Nelson and North Westland areas, and in the Kaimanawa and Ruahine Ranges. From the proportion of damaged shell seen, and a decline in the size of the live snail populations, Walker and Elliot concluded that possum predation is having a major detrimental effect on Powelliphanta superba, P. gilliesi, P. annectens, P. hochstetteri, P. lignaria, and P. marchanti.” |

DoC code of practice for aerial 1080 in kea habitat |
“Kemp et al. (2014 [unpublished]) identified the key predators of kea using a combination of nest cameras, corpse necropsy and inference… Nest cameras recorded visits by stoats, possums, ship rats, house mice and weka. Stoats were identified as the predator in 3 of the 16 nest failures…Two predation events were confirmed by corpse necropsy; one death by stoat predation was confirmed by DNA analysis and the other was predated by a falcon or a stoat” |

Can a landscape predator control regime be emplyed to ensure sustainable recruitment in endangered mohua (Mohua ochrocephala) populations, South Island New Zealand |
“All predated nests were checked to see if the sticky string around the tree had picked up hair from the predator. Unfortunately this method was not effective for mohua as only two predation events were confirmed by this method during the course of the study. The unknown category contains many possible scenarios including abandonment, inability to access the nest and cryptic predation events….The nesting success in the treatment area was still not sustainable. It was thought by the field workers that nests were being abandoned rather than suffering from predation events due to the fact that the banded females were often found after the nest had failed which is not normally the case.” |
