Acoustic feature measurements of male and female NZ bellbird (Anthornis melanura) song syllables

Acoustic feature measurements of 20,700 syllables (acoustic units) of male and female birdsong, from NZ bellbirds (Anthornis melanura). The measurements were extracted in Koe bioacoustics software (koe.io.ac.nz), on recordings from six sites in the Hauraki Gulf, northeastern New Zealand. The sites are Tawhiti Rahi island (Poor Knights island group), Lady Alice Island (Hen and Chicks island group), Hauturu (Little Barrier Island), Tawharanui Peninsula, Repanga (Cuvier Island), and Tiritiri Matangi Island.
