Spellbound On Tiritiri Matangi

New Zealand bellbird, Anthornis melanura was the Guardian’s ‘Mystery Bird’ on 24 November. “This bird is named for its gorgeous song, which consists of three distinct sounds that resemble the chiming of distant bells,” evolutionary biologist and ornithologist GrrlScientist writes for the daily blog. “Bellbirds from different areas in New Zealand have identifiable regional dialects. Their songs may vary enormously even over short distances and over time. Further, some people report that males and females of this duetting species sing different songs, at least during some parts of the year. And of course, juvenile song is identifiable too, because they are still practicing their song.” The bird pictured is an adult male photographed at Tiritiri Matangi Island, the restored island in the Hauraki Gulf.
