摘要: Abstract Stoats (Mustela erminea) are an important predator of many forest bird species in New Zealand, and more effective methods for their control being sought. Stoat using Fenn traps has been shown to prevent predation on mohua (Mohoua ochrocephala), but this technique is labour‐intensive costly use protection large areas habitat. We evaluated 1080 delivered eggs as a poison stoats. The lethal dose determined by captive field trials, attempts implement large‐scale operation have given inconclusive results. To clarify the effectiveness technique, we carried out further trials with radio‐tagged stoats Makarora Valley. Twenty animals were monitored radio tracking, data loggers video cameras recorded visits bait stations. precise time individual stoat ate egg could be from logger information, its fate was followed.
