The feeding behaviour of the Osprey Pandion haliaetus was studied at feeding grounds, feeding perches and nests in the Clarence Valley, north-east New South Wales, from 1991 to 1996. Foraging behaviour was found to be similar to that of Northern Hemisphere birds. Although birds were found to take mostly living fish, one record of passible […]

From 1979 to 1987, 7 080 birds, representing 17 species, were banded at Raine Island, and from 1979 to 1985, 849 birds, representing 3 species, were banded at Moulter Cay, MacLennan Cay, Sandbank No. 7 and Sandbank No. 8. Almost half (45.5%, n = 3 609) of the 7 929 birds were banded as adults; […]
Kleptoparasitism in birds is typically considered the piracy of food from one bird by another. This is an account of collaborative kleptoparasitic attacks by Dusky Woodswallows Artamus cyanopterus on a Restless Flycatcher Myiagra inquieta. The two woodswallows worked collaboratively to steal arthropod prey from the flycatcher with one woodswallow feeding the other with the stolen […]
The pattern and timing of nesting by 57 bird species in open eucalypt Eucalyptus forest on the northern tablelands of New South Wales (30 degrees 30″ S, 151 degrees 40″ E; 990-1390 m asl) were studied in the breeding seasons of 1988-1992, 1994, and 1996. The first nests were initiated in mid-July with numbers increasing […]
