Seabirds found dead on New Zealand beaches in 1983 and a review of albatross recoveries since 1960

Notornis, 32 (1), 23-41

R.G. Powlesland (1985)

Article Type: Paper

In 1983, 4,559 kilometres of coast were patrolled and 5,991 dead seabirds were found. A new record for the Beach Patrol Scheme was a pomarine skua (Stercorarius pomarinus). Unusual finds were yellow-nosed mollymawk (Diomedea chlororhynchos), Stejneger’s petrel (Pterodroma longirostris), white-tailed tropicbird (Phaethon lepturus), lesser frigate bird (Fregata ariel) and grey ternlet (Procelsterna cerulea). A wreck of long-tailed skuas (Stercorarius longicaudus) occurred mainly on Auckland West beaches in January and February. A summary is given of the coastal and monthly distribution for each species and subspecies of the 2,401 albatrosses found during the 1960-1983 period. Of the various coastal regions, albatrosses were found most frequently (number of birds per 100 km covered) on Southland beaches. The most frequently found albatross was the grey-headed mollymawk (Diomedea chrysostoma).

Variation within the redpolls of Canterbury

Notornis, 32 (3), 245-253

J.F.M. Fennell; P.M. Sagar; J.S. Fennell (1985)

Article Type: Paper

The measurements of the redpoll (Carduelis flammea) in Canterbury, New Zealand, were investigated. Variation in plumage colour are compared with study skins and published data for British redpolls. New Zealand and British redpolls are shown to differ and it is suggested that differences may be due to ‘founder effect’ rather than ‘hybridisation’ between two or more introduced races, as had previously been postulated. The occurrence of light-coloured plumage was more common in males. Females showed a much wider range of poll colour.

The distribution of Buller’s shearwater (Puffinus bulleri) in the North Pacific Ocean

Notornis, 32 (2), 109-117

T.R. Wahl (1985)

Article Type: Paper

From available records ranging from systematic surveys to casual observations, the known distribution of Buller’s shearwater (Puffinus bulleri) in the North Pacific Ocean is described. The birds arrive in subarctic waters in June and slowly expand northward and eastward as far as the Gulf of Alaska by August. The mid-ocean distribution after August is poorly known, but many birds, presumably non-breeders, are along the west coast of North America, at least from British Columbia to southern California, until late October-early November. Numbers observed along this coast have increased since the mid-1960s.

The North Island kokako (Callaeas cinerea wilsoni) in the western King Country and Taranaki

Notornis, 31 (2), 131-144

C.F.J. O'Donnell (1984)

Article Type: Paper

The distribution of the North Island kokako (Callaeas cinerea wilsoni) in the western King Country and Taranaki was recorded during summer 1980-1981. The survey confirmed that the kokako was widespread in the study area but showed that its range is continuing to shrink. The status of many populations is still uncertain. Kokako appear to have disappeared recently from large forest tracts in south-eastern and inland Taranaki and from large isolated forests in the north. Within large forest tracts kokako were not recorded in some locations where they had been present before 1970. Most kokako were in unmodified rimu-tawa dominant forest and habitat deterioration appears to be an important factor in their decline.
