Determining the spacing of acoustic call count stations for monitoring a widespread forest owl

Nocturnal species are challenging to monitor, but with advances in bioacoustic technology, acoustic monitoring is becoming a more affordable, efficient technique for monitoring cryptic species. We tested the suitability of acoustic monitoring as a potential national monitoring method for morepork/rūrū (Ninox novaeseelandiae), in beech forest within the Eglinton Valley, Fiordland, during spring 2009–2010.
