Seabirds found dead on New Zealand beaches in 1982 and a review of penguin recoveries since 1960

Notornis, 31 (2), 155-171

R.G. Powlesland (1984)

Article Type: Paper

In 1982, 3,705 kilometres of coast were patrolled and 6,957 dead seabirds were found. Large numbers of sooty shearwaters (Puffinus griseus) were found on Stewart Island beaches (mainly in July) and Auckland West beaches (November-December). Large numbers of blue penguins (Eudyptula minor) were found on Auckland West and Auckland East beaches in January-February and August-September. Unusual finds were single specimens of long-tailed skua (Stercorarius longicaudus), Black-fronted tern (Sterna albostriata), Arctic tern ( S. paradisaea) and little tern (S. albifrons). A summary is given of the coastaI and monthly distribution for each species of penguin found over the 1960-1982 period.

The relationships of the extinct Chatham Island eagle

Notornis, 31 (4), 273-277

S.L. Olson (1984)

Article Type: Paper

The extinct subfossil eagle of the Chatham Islands is referable to the genus Haliaeetus rather than to Ichthyophaga wherein originally described. Haliaeetus australis, as it should now be known, is more similar to northern species of the genus, particularly H. pelagicus, than to the geographically closer species H. leucogaster, and its ancestors probably colonised the Chatham Islands from the Northern Hemisphere rather than from Australasia.

Territories of South Island fernbirds

Notornis, 30 (3), 199-216

M. Barlow (1983)

Article Type: Paper

South Island fernbirds near Invercargill, Southland, were studied for two years. Adult birds had year-round preference for areas with low dense ground vegetation and emergent shrubs. The preferred habitat occurred in a linear strip along an estuary margin. Territories were contiguous and distributed in linear fashion along the strip. Territory areas varied from 530 m2 approximately to 2870 m2 approximately. Territories were strongly defended during the prebreeding and breeding seasons, and defended to some degree at other times. Juveniles were often found outside the preferred adult habitat. There were indications that total fernbird population needs may include an area adjacent to but exclusive of adult territory areas. Fire had a prolonged adverse effect on breeding habitat.
