Aspects of the biology of the Grey Falcon Falco hypoleucos in the Pilbara region of Western Australia

Category: Issue 1
Author(s): Sutton
>> Download Complete PDF | File Size: 211kb

The diet and breeding biology of two pairs of Grey Falcons Falco hypoleucos were studied in the eastern Pilbara region of arid north-western Australia during the second half of 1987, after average to above-average rainfall in the preceding six months. The two simultaneously active nests were old stick nests in riparian eucalypts, approximately 23 kilometres […]

Morphometric data are presented for eight specimens of the Grey Falcon Falco hypoleucos acquired since 1990 by Australian wildlife collections and wildlife care facilities, and for the first three wild-caught adult individuals of the species. Morphological characteristics are analysed and compared with other published material. It is suggested that adult and juvenile Grey Falcons can […]

Breeding productivity and diet of the Grey Falcon Falco hypoleucos were recorded in the Strzelecki Creek region of arid north-eastern South Australia in 1982–85 and 1995–2000, by systematic searches for nests (n = 4 found), inspection of their contents on repeat visits within a season by climbing or by pole-mounted mirror, and by analysis of […]

Some aspects of the biology of the Black Falcon Falco subniger

Category: Issue 1
Author(s): Stephen Debus, Olsen
>> Download Complete PDF | File Size: 327kb

Aspects of the biology of the Black Falcon Falco subniger were studied in South Australia in the 1970s, and the data on breeding biology not published elsewhere are presented here. Recent body-mass and associated data, and banding and recovery data, were sourced from museums, raptor rehabilitators and the Australian Bird and Bat Banding Schemes. Brood […]

Diet and breeding of White-bellied Sea-Eagles Haliaeetus leucogaster were studied at two sites in the subtropical Northern Territory of Australia over seven years: at Mary River (20 territories), characterised by a permanently high water level; and the Alligator Rivers at Kapalga (20 territories), characterised by high wet-season and low dry-season water levels. Overall diet comprised […]

Euthanasia of pest sturnids in nestboxes

Author(s): Christopher Tidemann, Kate Grarock, Daryl King
>> Download Complete PDF | File Size: 69.1kb

Nestboxes are commonly used as a research tool or for enhancing habitat quality for native hollow-dependent wildlife, but these objectives can be compromised if boxes are occupied by feral species, such as Common Myna Sturnus tristis and Common Starling S. vulgaris. Mynas and starlings exclude other potential nestbox users by actively harassing them, and by […]

In September 2009, three banded female Carnaby’s Black Cockatoos Calyptorhynchus latirostris were identifi ed at their nest sites by reading their leg bands. They had been banded as part of a 40-year study of the biology of a black cockatoo population at Coomallo Creek in the northern wheatbelt of Western Australia. Two techniques were employed […]

Clutch predation in relation to mean vegetation height at Northern Mallards’ Anas platyrhynchos nests

Category: Issue 2
Author(s): Fayaz Ahmad Ahanger, Mustafa Shah, Ulfat Jan, Bilal Bhat

Northern Mallards Anas platyrhynchos are the only species of wild duck currently breeding in Kashmir. In fact, Kashmir is the only territory within India where they breed (Bates and Lowther 1952). They are winter visitors to the valley of Kashmir, where they occur in huge numbers in wetlands and lakes. In spring (March and April) […]

An aberrant plumaged Chestnut Teal Anas castanea with a white neck-ring

Category: Issue 2

>> Download Complete PDF | File Size: 505kb

Plumage aberrations are not uncommon in wild birds (e.g. Gross 1965; Hosner and Lebbin 2006). These abnormalities can take on many forms, but albinism and leucism (sometimes wrongly called partial albinism) are the most common plumage aberrations in birds (Sage 1963; Gross 1965). Albinism is the complete loss of all pigments in both plumage and […]

Tool use by the Sandstone Shrike-thrush Colluricincla woodwardi

Author(s): David Lindenmayer, Karen Viggers
>> Download Complete PDF | File Size: 49.2kb

Tool use is widespread in primates but relatively rare in other groups of animals (Beck 1980). Within birds, tool use has been recorded in a range of species. Bark chips are used by the Brownheaded Nuthatch Sitta pusilla as part of foraging for insect prey on the island of Grand Bahama (Hayes et al. 2004). […]

Parental time-budgets and breeding behaviour of the Little Eagle Hieraaetus morphnoides in northern New South Wales

Category: Issue 3
Author(s): Stephen Debus
>> Download Complete PDF | File Size: 139kb

The breeding behaviour and parental time-budgets of a pair of Little Eagles Hieraaetus morphnoides were studied throughout 115 hours of observation from nest-building to fl edging at Armidale, on the Northern Tablelands of New South Wales, in spring–summer 2009. Supplementary observations were conducted on three other nearby pairs, and the breeding productivity of nine local […]
