Wintering silvereyes at bird tables in the Dunedin area

Notornis, 9 (8), 280-291

J. Kikkawa (1962)

Article Type: Paper

Fairly accurate estimates were obtained for the number of silvereyes visiting a feeding station in Dunedin and the amount of food energy required by these birds. From these estimates and the results of the enquiry sent to the public, it was found that in the part of Dunedin city (6,000 acres) where at least 147 people fed birds, more than 7,500 silvereyes spent winter in 1960 and consumed at least 240,000 Calories of artificial food per week. This is as much as one-third of the total energy required by the estimated population. It is likely, therefore, that the natural population of silvereyes is greatly influenced by artificial feeding.

Seabirds found dead in New Zealand in 1960

Notornis, 9 (7), 225-230

P.C. Bull; B.W. Boeson (1961)

Article Type: Paper

Beach patrols in New Zealand during 1960 covered a total distance of 638 miles and yielded 1,121 dead birds (44 species). Albatrosses, petrels and shearwaters constituted 80 per cent. of the total specimens, the most abundant species being Pachyptila turtur (307 specimens), Puffinus gavia (158) and Puffinus griseus (129). The finding of four sooty terns (Sterna fuscata) was unusual. Highest seabird mortalities were recorded during the period August to December, and rates of mortality were higher on the west coast of the North Island than elsewhere.
