Early fledging in the New Zealand Fantail Rhipidura fuliginosa fuliginosa


New Zealand Fantails Rhipidura fuliginosa fuliginosa form breeding pairs, which retain the same territories and can produce multiple clutches in a breeding season (Heather and Robertson 2005). Fantails have an incubation period of 13–16 days and have a nestling stage of 11–16 days (Heather and Robertson 2005). The minimum time recorded to fledging was 12 days and 11 hours (Blackburn 1965, 1996). Higgins and Peter (2002) however, recorded fledging time as early as ten days. During surveys of nesting success under taken from 1 November 2006 to 31 January 2007 in Tongariro Forest, Mt Ruapehu, New Zealand (39º12'S, 175º32'E) fledging (defined as chicks leaving the nest of their own free will) was recorded occurring earlier in some of the studied clutches than previously recorded.
