Field surveys of the Red Goshawk Erythrotriorchis radiatus were conducted in south-east Queensland in 1995 and again in 2001; in northern Queensland in 1999; and on Cape York Peninsula in 2000. In south-eastern Queensland, Red Goshawks were found at 25 localities in 1995, representing at least 10–12 (possibly up to 16) resident pairs; breeding was […]
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 […]
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 […]
