SUMMARYPratt, T.K., 1982. Additions to the avifauna of the Adelbert Range, New Guinea. Emu 82This paper reports previously unrecorded populations of thirty-two species of hill forest and montane birds from the Adelbert Range, Papua New Guinea. Three new subspecies are described:Rallicula forbesi parva, Sericomis nouhuysi adelberti, andAmblyornis macgregoriae amati.The avifauna of this range is impoverished, as are avifaunas of other isolated ranges in New Guinea. Adelbert species show subspecific affinities to populations from the ranges of the Huon Peninsula, or from the Central Ranges, or from both. Montane species may be restricted to only a very small part of the Adelbert Range.

SUMMARYFORD, J. 1982. Hybrid phenotypes in male FigbirdsSphecotheres viridisin Queensland. Emu 82: 126–130.Two distinctive forms ofSphecotheres viridishybridize in lower north-eastern Queensland: the yellow-breastedflaviventrisand grey-breastedvieilloti.Hybridization was quantitatively assessed in 1976–80 by collecting specimens and counting phenotypes of wild male birds. Two kinds of gradation in phenotype were discovered: a series in which the throat and breast varied from yellow through green to dark grey; and a series in which the throat and breast were white or various shades of grey. Most differences in coloration betweenflaviventrisandvieillotimay be explained in terms of two gene loci, one locus controlling deposition of yellow carotenoid and the other controlling melanin in the feathers on the throat and breast; hybrids with white on the throat and breast apparently have a combination of recessive alleles. Hybrids predominate in the region of Townsville and the hybrid zone is very broad. Contact appears to be secondary and may have existed for 9,500 to 14,000 years. A subspecific relationship betweenflaviventrisandvieilloti isconfirmed.

SUMMARYREILLY, P.N., and J.M. CULLEN, 1982. The Little PenguinEudyptula minorin Victoria, III: Dispersal of chicks and survival after banding. Emu 82: 137–142.Over 8,000 Little Penguins have been banded as chicks in Australia, mainly in the south-east. There have been 201 recoveries of dead birds away from the banding place besides numerous live records at the banding site and elsewhere. The young disperse rapidly after leaving their natal colony, with a strong tendency to move westward from Phillip Island, Victoria, the colony for which there is most information, particularly favouring an area centred on Cape Otway. Birds banded in New South Wales disperse northward and southward along the coast reaching as far as Tasmania in the south and Port Phillip Bay in the south and west.Some young birds return to their natal colonies to moult when one and two years old but their whereabouts in the intervals are not known. Some birds subsequently breed at their natal colony, others moult or breed or do both elsewhere. Survival after banding is influenced by the weight of the chicks at the time of fledging and whether they were raised early or late in the season.

SUMMARYBELL, H.L. 1982. A bird community of New Guinean lowland rainforest. 3. Vertical distribution of the avifauna. Emu 82: 143–162.The vertical distribution of a bird community in 2.5 ha of rainforest at Brown River, Papua New Guinea, was examined. The vertical distribution of 100 species, and of the density and biomass of the whole bird community, is shown. Distribution of biomass conformed generally to the vegetation density. Relatively small numbers of large birds, chiefly frugivores, occupied the higher strata while larger numbers of small birds, chiefly insectivores, occupied the lower. Few small insectivores occurred in the main canopy, their place being taken by facultative insectivores, both frugivorous and nectarivorous. With certain groups or species, e.g. sallying insectivores, the kingfisherTanysiptera galateo, and fruit-dovePtilinopus magniflcus, there were seasonal changes in vertical distribution. Many species fed higher in the early morning and moved down during the morning as temperatures rose. The presence of secondary vegetation and mixed-species flocks, and behaviour such as display, nesting, bathing and drinking all influenced the height frequented. In some species the sexes were observed at different heights.

SUMMARYLOWE, K. W. 1982. Feeding behaviour and diet of Royal SpoonbillsPlatalea regiain Westernport Bay, Victoria. Emu 82: 163–168.Royal Spoonbills were studied in Westernport Bay between 1977 and 1981. Birds were present throughout the year and counts of feeding birds and observations of leg-banded birds indicated that Spoonbills were sedentary except for some seasonal movement within the bay. Spoonbills fed preferentially on intertidal mudflats but also utilised seasonally-available freshwater habitats. Spoonbills are specialist feeders; the dominant food being a species of marine shrimp (Macrobrachium intermedium). The diet of Spoonbills appeared to differ between night and day because their prey exhibited pronounced nocturnal activity. During the day Spoonbills rarely took infauna of the mudflats. At night, when the infauna are more active, these taxa may become a more important part of the Spoonbill's diet.

SUMMARYNICHOLS, O.G., D. WATKINS, and E.D. KABAY, 1982 The distribution of the Red-eared FiretailEmblema oculatain relation to bauxite mining in the northern jariah forest. Emu 82: 169–172.The distribution of the Red-eared Firetail was studied in the northern jarrah forest and nearby areas of southwestern Australia. It was shown that, although the species is officially listed on the state's fauna list as‘rare, or otherwise in need of special protection’, it is much more widely distributed and abundant than was previously thought.There appears to be little conflict between bauxite mining and the conservation of the Red-eared Firetail. Firetails were never observed to inhabit upland and mid-slope areas of forest where almost all mining is carried out. Juvenile birds were observed within 150m of active mine pits.Most of the plants used by Red-eared Firetails are resistant to jarrah diebackPhytophthora cinnamomi, therefore it is unlikely that dieback will have a detrimental effect on the species.

SUMMARYSIBLEY, C. G. and J. E. AHLQUIST. 1982. The relationships of the Australo-Papuan sittellasDaphoenosittaas indicated by DNA-DNA hybridization. Emu 82: 173–176.The taxonomic relationships ofDaphoenosittawere examined by comparing the single-copy DNA sequences of radio-iodine (1251) labelled DNA of the Varied SittellaD. chrysopterawith the DNAs of thirty-eight other species, representing thirty-five genera, of oscine passerine birds (Passeres). Of the taxa examined,Daphoenosittawas found to be most closely related toPachycephala, Pitohui, Colluricincla, Monarcha, and other members of a large, primarily Australo-Papuan, assemblage which also includes such morphologically diverse taxa as the birds of paradise, crows, drongos, quail-thrushes, cuckoo-shrikes, fantails, scrub-robinsDrymodes, lyrebirds, scrub-birds, and bower-birds. There is no convincing evidence that the sittellas are closely related to the nuthatchesSitta, the Holarctic creepersCerthia, the Philippine creepersRhabdornis, the Afro-Asian creeperSalpornis, the Australo-Papuan tree creepersClimacteris, the Eurasian WallcreeperTichodroma, or the Coral-billed NuthatchHyposittaof Madagascar.Some Australo-Papuan taxa that are members of a separate major assemblage areMalurus, Sericomis, Acanthiza, the honeyeaters Meliphagidae, and the Australian chatsEphthianura.

SUMMARYGILL, B.J. 1982 The Grey Warbler's care of nestlings: a comparison between unparasitised broods and those comprising a Shining Bronze-Cuckoo. Emu 82: 177–181.Grey WarblersGerygone igataat Kaikoura, New Zealand, raised either a brood of up to four of their own young or one nestling Shining Bronze-CuckooChrysococcyx lucidus.The Cuckoo never weighed as much as four nestling Warblers of the same age, was visited with food less often than three or four Warblers, and had fewer faecal sacs removed. Therefore raising a Cuckoo to fledging required less effort in terms of feeding-visits and hygiene than raising a brood of several Warblers. Single Cuckoos were brooded more on average than three or four Warblers of the same age, for a greater part of the nestling period and in longer spells. Thus the pattern of brooding by adult Warblers was not determined entirely endogenously but was modified by external stimuli.
