The diet of radio-tagged moreporks (Ninox novaeseelandiae) was studied at Pureora Forest from May to December 1997. An examination of 187 pellets yielded 1226 prey items. Approximately 99% of the diet was invertebrates; the commonest items being beetles (48.6%), stick insects (25.6%) and weta (11.8%). Vertebrate prey included silvereye (Zosterops lateralis) and rodents in small numbers. The diet varied significantly from month to month.
