Longevity of a whitehead (Mohoua albicilla) on Tiritiri Matangi Island | Notornis and Birds New Zealand

[摘要] [First paragraphs...] At c.0800 h on 6 Nov 2006, PB and TC caught a whitehead (Mohoua albicilla) while mist-netting on Tiritiri Matangi I, Hauraki Gulf, North I, New Zealand. The net was set in “Bush 1”, on the northwestern side of the island. The bird carried a metal band (B57955) and 2 (green, blue) faded, inter-twined wrap-around plastic bands: the band combination could have been either metal-GB or metal-BG. It was thought to be male because it had a bright white head (Gill & McLean 1986) and an enlarged cloacal area. The only whiteheads that had been banded recently on the island had all been processed by NL and received split colour bands. We therefore thought that this whitehead was from the original trans-located population which was transferred to Tiritiri Matangi I from Little Barrier I in 1989 and 1990, which would mean that it was at least 16 years old. age of 8 years 7 months for another Little Barrier I bird (Gill 1993).
