Breeding biology of North Island robins (Petroica australis longipes) in Pureora Forest Park

Notornis, 47 (2), 97-105

R.G. Powlesland; J.W. Knegtmans; I.S.J. Marshall (2000)

Article Type: Paper

Breeding of North Island robins was monitored at two sites in Pureora Forest Park, central North Island, during the 19961 97 and 1997/98 breeding seasons. A total of 146 nests was found. First clutches were laid in September-October (mean: 20 September) and last clutches in November-January (mean: 17 December). Pairs had time to rear three broods during the breeding season (September-March), although most reared only two. Nest materials and nest location are described: mean nest height was 5.3 m (range 1.0 – 13.6). Mean clutch size was 2.60 (clutches of 2 or 3). Monthly mean clutch size increased from September to November, then decreased. The breeding biology of the North Island subspecies of robin at Pureora was similar to that of the South Island robin at Kaikoura. Nesting success improved dramatically after brushtail possums were poisoned by aerially distributed 1080 (sodium monofluoroacetate) baits, because mammalian predators were also poisoned. Robins are easy to monitor, and predation is a common cause of nest failure, so the species is potentially a valuable indicator of predator activity.

Bird fauna of Niue Island in 1994-95

Notornis, 47 (1), 39-53

R.G. Powlesland; J.R. Hay; M.H. Powlesland (2000)

Article Type: Paper

An annotated checklist of the bird species of Niue Island in the southwest Pacific is provided from published and unpublished sources, and from observations during April-May, September, and December 1994. Results for common species were derived from five-minute counts, numbers seen per kilometre while travelling by motorcycle along roads, and single species surveys. The number of species on Niue is 31 (6 seabirds, 10 shorebirds, and 15 land birds). The common noddy (Anous stolidus) was confirmed as nesting on the island. Recommendations are made for the future management of the hunted Pacific pigeon (Ducula pacifica) and the scarce blue-crowned lory (Vini australis).
