To simulate a seabird mortality incident, marked floats (total 375) were dropped in batches of five at 9 km, 35-45 km and 50-90 km east of Wollongong, New South Wales during each of 25 cruises from June 1985 to October 1987. Overall, 85 (22.7%) were recovered between Budgewoi (1 10 km N) and Bermagui (198 […]
The results are reported of a three-day study of helicopter effects upon small birds and breeding White-bellied Sea-eagles on a remote, rarely-visited Queensland island. Regular close passes by the helicopter above a sea-eagle nest, compounded by the presence of people and rain, probably caused breeding failure. Habituation to such activity is most unlikely to occur […]
The WA Rehabilitation Banding Group was formed to evaluate the success of returning sick, injured and orphaned birds to the wild. Over eight years 3 578 birds of 123 species were banded and during this time 132 recoveries were made. Time between release and recovery was more than three months in over 50 per cent […]
The gut passage rate of Silvereyes Zosterops lateralis, was measured with fruits of Coprosma quadrifida. The rate of passage of seeds was measured when fed to birds whose guts were empty and compared to the rate when fed to birds that had eaten previously. Gut passage rates ranged from six to 28 minutes but was […]
Bridled Terns Sterna anaethetus breeding on Penguin Island in south-western Australia allow much closer human approach than they do on remote Bridled Island off the Pilbara coast. This difference in behaviour is attributed to the gradual habituation of Penguin Island terns to the regular presence, and relatively predictable activity, of people at that colony. The […]
Millions of seabirds of 22 species breed on over 78 islands surrounded by the Great Barrier Reef Marine Park (GBRMP) of Australia. Although many of the islands are Queensland national parks, some are part of the GBRMP, are vacant crown land or are under a lease arrangement. The importance of the islands to the breeding […]
