Robinson, D. 1992. Why do Flame Robins Petroica phoenicea migrate? A comparison between the social and feeding ecologies of the Flame Robin and Scarlet Robin P. multicolor. Corella16: 1-14. (Dept. Botany Zool., Monash Univ., Clayton, Vic. 3168, Australia).

Comparisons between the ecology of Flame and Scarlet Robins at a sympatric breeding site suggested that Flame Robins migrated during the winter months because of a decline in the availability of their major prey. During the nine months that Flame Robins were present at the breeding site, they foraged for flying insects twice as often as did Scarlet Robins. Scarlet Robins foraged more often for ground-dwelling prey. Flying insects are a very seasonal food resource, present mostly during the warmer months. Ground-dwelling arthropods remain relatively more common in winter. Thus, Flame Robins migrated from their breeding grounds once food abundance decreased and competition for remaining prey increased in the autumn months. Scarlet Robins were able to find sufficient food to remain at their breeding grounds throughout the year. Severe competition for territories in breeding habitat may have been a further selection pressure on Scarlet Robins to remain at their breeding grounds throughout the year, since territory turnover was low

Morphological comparisons indicated that Flame Robins showed long-term adaptations to their winter environment and winter feeding behaviour (hop-gleaning on the ground). Such adaptations imply that migration may be an ancestral trait within this species rather than a recent event, and that Flame Robins have long moved between wintering and breeding grounds to exploit seasonally abundant supplies of food.

Most arid zone ducks are nomadic or display a combination of movement patterns. Arid zone ducks that breed in the southern hemisphere (but not those that breed in the northern hemisphere) lay in more months of the year than do non-arid zone ducks. Clutch sizes of ducks that breed in dry environments are higher than those of sedentary ducks that nest in mesic lands, and similar to clutch sizes of migratory ducks that breed in non-arid habitats. Durations of incubation and fledging in arid zone ducks approximate those of sedentary species, but exceed those of annually migratory anatids that breed in mesic lands. Thus, incubation and fledging times in waterfowl that nest in arid country do not conform with the brief periods of flooding of many wetlands in these low rainfall areas.

Assessment by routine morphometric analysis found no geographic variation in the Regent Honey-eater Xanthomyza phrygia but distinguished significant sexual dimorphism in size, intensity of plumage colour and extent of warty skin on the face. Seasonal distribution of records indicates that coastal south-eastern Australia forms part of the core breeding range of the species.

The density of nesting burrows of the Wedge-tailed Shearwater Puffinus pacificus was measured in 224 quadrats on Heron island, Great Barrier Reef. Field measurements of the unconfined compressive strength of the soil material were made for each quadrat. Lowest burrow densities occurred in quadrats at both upper and lower ends of the soil strength range, increased burrowing success at sites where soil is not so loose as to collapse, but not so compacted as to inhibit burrowing is indicated. .Island development which results in soil compaction may, therefore, inhibit P. pacificus nesting.

Silver Gull populations have increased substantially in the past 50 years. This is primarily because they are scavengers and have been able to utilize human refuse. They have been implicated as problems to aircraft movements and water supplies, because they defaecate in water reservoirs and are known to be agents of human enteric diseases. Should a management programme be instigated to reduce gull numbers, a major priority should be to reduce access to artificial food sources.

Increase of diversity of insectivorous guilds compared with control area at 8 months post-fire. Increase of diversity of insectivorous guilds compared with control area at 8 months post-fire.

Members of the New South Wales Field Ornithologist‚s Club counted the number of species and individual birds in Weddin State Forest and Weddin Mountain National Park, parts of which were affected by fire in January 1975. This was the first study of the effects of fire on bird populations in White Cypress Pine habitat. Counts were made eight months after the fire in October 1975 and again eight years later in October 1983, comparing the birds seen in burnt and unburnt bush. At the eight month count, there were 59 species and 100 individuals recorded in the unburnt area, compared with 50 species and 225 individuals in the burnt area. In 1983, however, over the same areas, there were 87 species and 660 individuals in the burnt area and 63 species and 340 individuals in the unburnt area. The increase in the diversity of birds eight years post-fire occurred in the insectivorous ground, shrub and foliage foraging guilds.

Birds in sclerophyll (eucalypt) forests and rainforests in northern NSW were counted monthly over 30 months between 1977 and 1982. The bird communities of two dry sclerophyll forests were similar, a feature of both being the high frequency of lorikeets and honeyeaters (43-55% of all birds). They showed greater similarities to eucalypt woodland communities (elsewhere in NSW) than to moist forest communities. Coastal wet sclerophyll forest shared the same number of species with both dry sclerophyll forests and rainforests, but a greater affinity with the latter was indicated by the dominant species. The species composition of dry and subtropical rainforests were similar, although relative abundance values for many primary rainforest species, particularly the larger frugivores, were lower in dry rainforest. No exotic species were recorded from any site. Seasonal patterns were similar for all sclerophyll forests. Species numbers were generally highest in autumn and/or spring, and lowest in summer. Numbers of individuals were highest in winter and lowest in summer, a pattern that differs from that reported from some eucalypt forest and woodland communities elsewhere in south-eastern Australia. In the rainforests, both the numbers of species and of individuals were highest in summer and lowest in winter, contrasting with the seasonality of the sclerophyll forests.

 

Congreve, P. 1992. Relationships of age, moult and plumage in the White-cheeked Honeyeater near Beverley, Western Australia. Corella 16: 89-92. (2 Edwards St. Beverley, WA 6304, Australia).

Wing and head/bill measurements of 415 White-cheeked Honeyeaters Phylidonyris nigra taken at initial capture and again at subsequent retraps are compared to establish growth patterns. A plumage sequence from juvenile to adult is presented. Moult records are examined to ascertain the role moult plays in the division of age classes into the three age groups of Juvenile, Immature and Adult. From the analysis of these data. some changes are suggested in the application of the present age codes used for banded birds, in order to relate them to the age groups and terms commonly used to describe age in birds.

Waterbirds were monitored at approximately three-week intervals from June 1979 through May 1987 at Minden Dam, south-east Queensland. Thirty-four species were observed, 3 to 19 species in each count. Mean counts were highest for Dusky Moorhen, followed by Eurasian Coot, Little Black Cormorant, Pacific Black Duck, Cattle Egret and Australasian Grebe. These species, except the Cattle Egret and Eurasian Coot, were present in 75 per cent of counts, as were also Purple Swamphen and Little Pied Cormorant.

Total numbers of birds and numbers of seven species (Plumed Whistling-Duck, Pacific Black Duck, Grey Teal, Hardhead, Masked Lapwing, Black-fronted Plover and Black-winged Stilt) increased significantly as the water level in the dam fell. Numbers of ten species were inversely correlated with rainfall in the preceding 100 days. In contrast, numbers of Little Black Cormorant and Little Pied Cormorant decreased as water level fell and as rainfall in the preceding 100 days was lower. Numbers of Australasian Grebe, White-faced Heron, Intermediate Egret, Pacific Black Duck and Dusky Moorhen were highest in winter, while those of Little Black Cormorant, Little Pied Cormorant, Cattle Egret, Plumed Whistling-Duck and Black-winged Stilt were highest in summer.

 

 
 
 
 
 
 
 
 
 

Minden is rich in waterbird species because of its permanence and the diverse range of habitats. The predominantly inverse correlations with depth suggest that it was a local refuge as nearby habitats diminished during dry periods. The diversity and functioning of the dam is threatened by introduced water weeds and rural residential development so careful management is required to maintain its attractiveness to waterbirds.

A resident but fluctuating population of Magpie Geese was recorded on the central Queensland coast during twice monthly counts on 13 wetlands between February 1987 and December 1989. The mean population on these wetlands in 1987 was 1 225±136SE (n=23), in 1988 771±132SE (n =25), and in 1989 2848±290SE (n=27). Successful breeding was recorded in 1988 and 1989 on four wetlands dominated by Eleocharis spp. with goslings, fledglings and immature Magpie Geese observed amongst adult flocks on these wetlands.

A large colony of pelicans bred on three islands in Lake Eyre South during early 1990. A maximum of 90 000 chicks fledged from an estimated 104 000 eggs laid. The chicks which hatched late in this season experienced a greater mortality than the chicks which hatched early. Banding the young was a useful tool for determining nestling survivorship and appeared to have a minimal effect on the mortality of late-hatched young.

In Gentoo Penguin faecal samples taken from both sides of the Heard Island Spit, the most common prey was Parathemisto gaudichaudii followed by fish. There were significant differences in the diet between the north and south sides of the Spit, only three kilometres apart. The main difference was the presence of Euphausia vallentini in 46.7 per cent of samples from the north side of the Spit and its complete absence to the south. In addition, fish were more commonly taken on the north side and there were significant differences in the species of fish taken.
