Gosper, D.G.  1986.  Birds in the Richmond River district, N.S.W., 1973-1983. I. Distribution.  Corella 10: 1-16.

Distribution maps are given for 333 bird species recorded in the Richmond River district from 1973 to 1983.  Presence and breeding are plotted by 10' squares.  Local distribution patterns are discussed in relation to gross environmental factors.

White, J.M.  1986.  Breeding of Black Swans on two New England lagoons.  Corella 10: 17-20.

The breeding of Black Swans Cygnus atratus on Llangothlin Lagoon Game Reserve and Little Llangothlin Nature Reserve both during and after the 1981-1983 drought is reported.  Breeding success rates ranged up to 47% during the drought and 68% afterwards.  A possible link between low breeding activity, hunting pressures. and the legal status of the lagoons is discussed

McFarland, D.C.  1986.  Presence of ticks on the heads of Honeyeaters in New England National Park.  Corella 10: 25-28.

Ten species of honeyeater and three species of thornbill, present in New England National Park, were examined for ticks.  Approximately 5% of the 1229 birds inspected had ticks present on their heads  Most infected birds were caught in winter.  I suggest that ticks wait on the flowers of Banksia spinulosa for prospective hosts, and that inter-specific differences in infestations among the birds are due to differences in their habitat selection foraging behaviour and morphology.  Most ticks were found around and in front of the eyes.

McFarland, D.C. & P.F. Sale.  1986.  Behaviour and ecology of two species of Honeyeater.  Corella 10: 37-45.

During the autumn and winter of 1980, the general behaviour and ecology of New Holland Honeyeaters and Little Wattlebirds was studied in heath and dry sclerophyll forest in the Royal National Park, NSW.  The availability of certain foods (flying insects and nectar) was also measured.  Both bird species had similar time budgets and engaged in inter- and intraspecific aggression.  Hawking activity did not appear to be affected by the abundance of flying insects on either a daily or seasonal basis.  Each honeyeater exhibited preferences in the plants used as nectar sources.  Even though the abundance of all honeyeaters in the area increased as the density of Banksia inflorescences increased, when individual species were examined only two of the five present showed significant relationships.

Taylor, I.  1986.  The song of the Superb Lyrebird in the Australian Capital Territory.  Corella 10: 46-51.

The song of the Superb Lyrebird Menura novaehollandiae was recorded at five sites in the Australian Capital Territory (A.C.T.).  It was found that a number of features were common to all the songs, namely the species own calls and the mimicked calls of the Grey Shrike-thrush, Pied and Grey Currawongs, Red Wattlebird, Crimson Rosella and Yellow-tailed Black-Cockatoo.  These features accounted for 70-90% of each bird‚s total output and suggest that the repertoires of lyrebirds in the A.C.T., are largely similar.  The greatest distance between two lyrebirds sharing these similar repertoires was 70 km, which is considerably further than had previously been thought.

A simple method is proposed for estimating relative abundances of forest birds.  An unmarked area of about 3 ha is searched for 20 minutes and all birds seen or heard are counted.  The method has been used widely in Victoria and its scope and limitations are discussed.

Maddock, M.  1986.  Fledging success of Egrets in dry and wet seasons.  Corella 10: 101-107.

Fledging success for Great, Little and Intermediate Egrets at a breeding colony at Shortland (Newcastle, N.S.W.) was found to increase significantly between the wet 1982-1983 and the dry 1983-1984 breeding seasons, whereas for Cattle Egrets there was no significant difference.  Evidence of diet changes obtained during the 1984-1985 drought season. coupled with observations of behaviour in the colony during breeding seasons, suggest the hypothesis that the relationship between seasonal food availability and lethal aggression between siblings is the critical factor at work in determining breeding success.

Kingsford, R.T.  1986.  The moults and plumages of the Maned Duck Chenonetta jubata on the Southern Tablelands of N.S.W.Corella10: 108-113.

The moults and plumages of a wild population of Maned Ducks Chenonetta jubata were studied.  Descriptions of duckling plumage development are presented so that they may be used to identify duckling age in the field.  Characteristics of a distinct juvenal plumage are also described.  The distribution of body moult shows a peak in moult activity at the beginning of the year and this, compared with the existence of a male "eclipse" plumage late in the year, suggests that there may be two body moults per year.

Observations on Beach Thick-knees breeding at Red Rock on the N.S.W. north coast are presented.  Plumage details of juvenile and adult birds are discussed and measurements of juveniles included.  Eleven breeding attempts were observed and the details of these are tabulated.  Breeding success was affected by both natural phenomena and human activity.  Other aspects of breeding activity and behaviour are presented.

Between January 1984 and December 1985 the corpses of 127 birds of 32 species were collected during routine journeys along secondary roads in an area of approximately 40 km2 near Manjimup in the south west of Western Australia.  Peak months were November to March and 57% of the casualties were juveniles.  Ten banded birds were recovered during the study.
