Observations were made at a nest attended by six Orange-winged (Varied) Sittellas, three of which were colour-banded near Armidale, New South Wales.  The nest was watched for 15 hours, which included late incubation and nestling periods.  Only one bird, a female, incubated and brooded.  Five group members, including two juveniles from a previous brood in […]

Observations on Eurasian Coots Fulica atra, breeding near Manjimup, Western Australia, between 1975 and 1978, are given together with details of average clutch size, replacement clutches, predation and mortality.  Nest sites, construction and nesting materials are discussed.

Incubation and nestling periods of Australian birds, particularly small passerines, seem not to have been much studied and in general are not known accurately.  Details of incubation and nestling periods, collected for 25 species at Moruya, New South Wales, are presented.

Potential uses of captive raptors for research are discussed.  A selection of papers on incubation, clutch size, fertility, photoperiod, eggshell thinning and DDT, taxonomy, general biology, development of young, visual acuity, veterinary aspects, plumage changes and metabolism is reviewed.

Census counts were made in dry sclerophyll forest. and a clearing along a power-line, at Black Mountain Reserve, A.C.T., on 156 days between March 1974 and April 1975.  There were seasonal changes in both species and numbers in each site.  There were more species and individual birds in the clearing than in the forest.  Most […]

Between 1970 and 1975, 1 128 Galahs and 685 White-tailed Black-Cockatoos were marked with wing-tags so that the birds could be individually identified without resorting to re-trapping.  Tags have been worn by some cockatoos for eight years and do not appear to have interfered with their behaviour or reproductive success.  Similar wing-tags have been used […]
