A population of Sulphur-crested Cockatoo Cacatua galerita at Ashfield, New South Wales, was observed over a four year period. The birds were intentionally habituated to human observers and contact with humans was positively reinforced. The habituation process allowed behaviour patterns to be observed at distances of 0.5-3 m which is closer than other studies on […]
Thirty-two single-stage transmitters were attached to ten species of waders as part of a study on nocturnal habitat use. Three variations of a method used previously to attach transmitters to waders were compared. The aim of the comparison was to see if less disruptive variations of the standard attachment technique could provide similar retention times. […]
The breeding activities of Wedge-tailed Shearwaters at Raine Island, in the far northern section of the Great Barrier Reef, have not been quantified to date. In December 1995, 58 per cent of burrows inspected with a ‘burrowscope’ were occupied, 52 per cent with incubation or a chick, so approximately half of the estimated 3 661 […]
