Breeding Seasons

Malleefowl nests were surveyed by air, in six breeding seasons, in Round Hill Nature Reserve in central New South Wales. A technique for marking the nests from a helicopter so that they can be easily relocated was used. In an area of 20 800 ha, a total of 19 1 old nests were marked, only three nests being used for breeding in 1979-80. Correction factors from a ground survey show that about 43% of the nests present were found in 22 days aerial survey. The results show a very low population of malleefowl on Round Hill Nature Reserve and suggest a decline in the population in the last few decades.

The Impact

To provide an estimate of kangaroo numbers for harvest management, a survey was designed for an area of 29 500 km2 encompassing the agricultural and grazing lands of the Braidwood, Cooma, Goulburn, Gundagai and Yass Rural Lands Protection Board (RLPB) districts in south-east New South Wales. An aerial survey using a helicopter was considered more efficient than ground survey because of the size of the area, relatively high relief and dense tree cover, and the need for regular monitoring. Tree cover and landscape relief was used to stratify the five RLPB districts into areas of probable high, medium and low kangaroo density. Kangaroo density estimated from helicopter surveys conducted in the Northern Tablelands of New South Wales was used to suggest densities and thereby allocate survey effort in each stratum. A survey comprising 735 km of transect line was conducted in winter 2003 with a target precision of 20%. The survey returned an estimate of 286 600 ± 32 300 eastern grey kangaroos for the whole of the proposed south-east New South Wales kangaroo-management zone. In 2004, a trial harvest of slightly less than 15% of this estimate was taken. Success of the trial will be determined by the impact of harvesting on the population’s dynamics, by landholder and industry participation, and by the capacity to monitor population size, harvest offtake and compliance with regulations.

Populations of waterfowl of three game species, the Pacific black duck Anus superciliosa, grey teal A. gibberifrons, and maned duck Chenonetta jubata, were assessed by aerial survey in October 1983 within a survey region of 2 697 000 km2 of eastern Australia. The numbers of each species were assessed on all surface waters of over 1 ha, and on a sample of smaller surface waters within 10 survey bands each 30 km wide and spaced at intervals of 2� latitude from 20�30' to 38�30'S. The area within the survey bands was 324 120 km2, which gave a sampling intensity of 12.0% of the land surface area. The area of features shown as wetlands or water impoundments within the survey bands on 1 : 2 500 000 topographic maps was 19 200 km2 or 11.2% of the total area of these features in the survey region. The area of surface waters surveyed was assessed at 465 300 ha. Assessments of populations of each species were tallied for wetlands by grid cells of 6 min of 1� longitude along the survey bands (258-309 km2 depending on latitude). Distributions were then mapped, with log*10 indices of populations in each cell. Distributions of the black duck and grey teal showed a pattern of intense aggregation in limited numbers of cells, that of the maned duck was more evenly distributed. The major concentrations of the Pacific black duck were recorded in northern New South Wales and the south-eastern, western, central eastern and central coastal regions of Queensland; those of the grey teal were in south-western, western and northern New South Wales and central-eastern Queensland; the maned duck was broadly distributed over inland New South Wales with the exception of the far west, inland southern Queensland, and central northern Victoria.

Breeding Seasons

The regent honeyea ter, Xanthomyza phrygia, is an endangered woodland bird whose range and population size have decreased in the last thirty years. Suggested reasons for this decline include abnormal breeding behaviour, poor reproductive output, and excessive inter- and intra-specific aggression. This study investigated the breeding behaviour and aggressive interactions of regent honeyeaters during the nest construction, incubation, nestling, and fledgling stages in two consecutive breeding seasons in the Bundarra–Barraba region near Armidale, New South Wales. The female was entirely responsible for nest construction and incubation, which is typical of many honeyeaters. Both parents fed the nestlings, and at a similar rate, although only the female brooded chicks on the nest. Both parents fed the fledglings. The mean frequency at which nestlings (23 times per hour) and fledglings (29 times per hour) were fed is the highest published rate of any non-cooperative honeyeater. Breeding males were involved in significantly more aggressive interactions with conspecifics and other nectarivores than were females, although the overall percentage of day-time spent in aggression for both sexes was low (2.5%). It appears that abnormal breeding behaviour, poor reproductive effort, or excessive aggression are not experienced by this species in northern New South Wales, and that other factors are likely to be responsible for its current low population level.

ABSTRACT A population of the Northern Long-nosed Potoroo Potorous tridactylus tridactylus in Tyagarah Nature Reserve on the far north coast of New South Wales was first recorded in 1985. In 1992, a cage-trapping study captured 15 individuals in the central section of the reserve and the population was estimated at 80–90 individuals at that time. A subsequent cage-trapping study in 2004 captured four individuals in the southern section of the reserve, but further cage- and camera-trapping surveys in 2009 and 2012 failed to detect any individuals. Additional camera-trapping surveys between 2012 and 2015 and more intensive surveys between 2015 and 2016 also failed to detect any individuals. The lack of detections from targeted surveys over seven years between 2009 and 2016 suggests that the Tyagarah population of the subspecies has been lost. Reasons for this loss are unclear but may be due to a combination of factors including isolation of the reserve by urban development and highway upgrades, a lack of fire for 40 years, competition for food with the local population of the Australian Brush-turkey Alectura lathami, prolonged drought and possibly, predation by the Red Fox Vulpes vulpes and non-target effects of predator control programs.

Leaf Composition

Changes in the nutrient-element composition of leaves of 'Trevatt' apricot were measured monthly during the 1971-72 and 1972-73 seasons in New South Wales. The rate of change of leaf composition was least during January-February. Thus, leaf composition standards should be based on January- February samples and diagnostic sampling should be confined to this period where possible. Correction factors for adjusting the composition of early or late samples back to January 31 levels, were calculated from polynomials with time fitted to the leaf composition data. A survey of the leaf composition of well-managed 'Trevatt' apricot orchards was conducted each January from 1971 to 1973 in New South Wales and Victoria. Percentages of orchards classified as low to deficient (-), and high to excess (+) for various nutrients were as follows : New South Wales (averages of 1971 to 1973) N -41 ; P +37; K +49; Mg +56; Fe +1 9 ; Zn -18. Victoria (averages of 1972 and 1973) N -21 and +32; K +10; Fe -35; Mn +17; Zn -20.

Habitat utilisation by sympatric red kangaroos, Macropus rufus, and western grey kangaroos, M. fuliginosus, was monitored by aerial survey. Red kangaroos used floodplain and sandplain with equal intensity. Western grey kangaroos favoured floodplain and utilised woodland on both landforms relatively more than did red kangaroos. Movements of kangaroos between sandplain and floodplain paralleled changes in pasture condition. Red kangaroos responded to pasture growth, moving to sandplain immediately after rain. Western greys followed up to 3 months later, the increase in use of sandplain being weakly correlated (r = 0.70) to an increase in pasture biomass. There was no evidence of any temporal change in use of either woodland or open plain by either species.

The dietary items fed to regent honeyeater, Xanthomyza phrygia, nestlings and fledglings by adults were recorded in two consecutive breeding seasons in the Bundarra–Barraba region west of Armidale, New South Wales. Insects were the most common dietary items fed to juveniles (53% of identified items), followed by lerp (26.5%) and nectar (20.5%). Nestlings were fed mostly insects (58% of feeds), and carbohydrates (nectar and lerp) made up the rest of their diet. Fledglings, however, were fed mainly carbohydrates (nectar and lerp comprised 61.2% of all items) while protein from insects was the other major component of their diet. Males tended to feed juveniles more insects than did females, although there were no significant divisions of labour between parents in selecting dietary items for nestlings or fledglings. This study highlights the importance of insects and lerp in the diet of juvenile regent honeyeaters, and the diversity of plant species on which their parents foraged. The species shows a broader resource selection than was found in previous studies which considered the species to be highly nectarivorous and selective for a few key eucalypt species. The importance of insects and carbohydrates other than nectar in the diet of the regent honeyeater needs to be recognised in the development of conservation strategies for the species.

The significance of inland wetlands to Australian waterbirds has been overlooked until recently. One important area identified from regular aerial survey centres on the Paroo River in north-western New South Wales. Between April 1983 and December 1985, a period covering a major flood, waterbird populations were estimated on five wetland systems associated with the Paroo during 14 trips. Fifty- three waterbird species were recorded with the anatids, Anas gibberifrons and Malacorhynchus membranaceus, accounting for 75 per cent of total estimated populations. Most breeding events were observed in those wetlands dominated by Muehlenbeckia florulenta (lignum). Breeding accounted for shifts in waterbird populations between wetland systems. A model of waterbird usage of the five wetland systems in relation to a complete flood event is described. The importance for waterbird conservation of wetlands used for breeding and maintenance of populations between flood events, and threats to the integrity of these wetlands are discussed.
