SUMMARYSchodde, R., and I. J. Mason. 1976. Infra-specific variation inAlcedo azureaLatham (Alcedinidae). Emu 76:161–166. Three subspecies ofAlcedo azureaare recognized as occurring in Australia:diemenensisin Tasmania,azureain southern and eastern Australia north to the Cairns-Cooktown area andruficollarisin northern Australia between the Kimberley Division and Cape York Peninsula. They are distinguished by size and intensity of colour on the ventral surface and flanks;azureaandruficollarisare probably linked by steep clines in these characters between Cairns and Princess Charlotte Bay. The distinctive first-year plumage, not considered in most previous analyses of geographical variation, is described for Australian forms. Relations with races outside Australia are discussed.

摘要:
SUMMARYSeebeck, J. H. 1976. The diet of the Powerful OwlNinox strenuain western Victoria. Emu 76: 167–170.Analysis of pellets shows that the most common item of prey is the Ringtailed Possum. The Sugar Glider is taken less commonly and other vertebrates and invertebrates only occasionally. A possible instance of scavenging is reported. The relation between the Owl's dietary needs and its conservation is discussed.

摘要:
SUMMARYMACLEAN, G. L. 1976. A field study of the Australian Pratincole. Emu 76: 171–182.The Australian PratincoleStiltia isabellawas studied in north-western New South Wales in the summer of late 1974. The first birds were seen in the study area on 1 October and the last departed toward the end of December. The birds fed on open shorelines of dams and pans and on roads. They nested in loose colonies on gibber plains about one kilometre from water. They fed on insects caught on the ground or on the wing. The clutch was two eggs laid on the ground without a scrape. Both sexes incubated and cared for the young. During incubation nest-relief occurred every hour and a half. After hatching, the parents led the young to a refuge under a nearby shrub or grass tuft. Adults did not seek shade in hot weather; they withstood heat well but drank often at the nearest water.Stiltiais closely related to the genusGlareolabut resembles the coursers in some respects. It therefore represents a link between the subfamilies Cursoriinae and Glareolinae.

摘要:
SUMMARYDiamond, J. M., and A. G. Marshall 1976. Origin of the New Hebridean avifauna. Emu 76: 187–200.As background, the physical environment and avifauna of the New Hebrides in the Southwest Pacific are briefly described. The major routes by which birds invaded the New Hebrides are from Australia (possibly via New Caledonia) and from New Guinea via the Bismarcks and Solomons, with a minor route from Fiji. From the New Hebrides, birds in turn colonized New Caledonia, Fiji and Polynesia, the Solomons in a strikingly stratified pattern, the Bismarcks scarcely and New Guinea and Australia not at all. The concept of faunal dominance is supported by the asymmetry of these fluxes of species: the ratio of species exchanged between two archipelagos deviates further from 1.0 than does the ratio of the archipelagos' areas. Species that colonize archipelagos‘upstream’towards the source of colonization often become restricted to small or remote islands, poor in species, thereby generating many of the supertramps of the Pacific. Appendices summarize sources of information about New Hebridean birds and, for each species, its island-by-island distribution within the New Hebrides, extralimital range, closest relatives and references to taxonomic studies.

摘要:
SUMMARYZ ANN, R. 1976. Distribution, status and breeding of Black-throated FinchesPoephila cinctain northern Queensland. Emu 76: 201–206.Two subspecies, which have rumps of different colours, are sympatric in some areas at the base of Cape York Peninsula. Interbreeding occurs in one area but not in others. The black-rumped form appears to be extending its range.P. c. atropygialiswas studied in detail near Mareeba, where it was found in small flocks and nested in colonies. The distribution, location and structure of nests are described. Breeding behaviour is similar to that of the Long-tailed FinchP. acuticauda.

摘要:
SUMMARYMACLEAN, G. L. 1976. A field study of the Australian Dotterel. Emu 76: 207–215.The Australian DotterelPeltohyas australisinhabited sparsely vegetated claypans and gibber plains in western New South Wales. Non-breeding flocks averaged 13 birds, but one flock of 99 was counted. Activity within a flock was highly co-ordinated. Only two vocalizations were noted. Predators, anti-predator behaviour and comfort movements are described. The Australian Dotterel is mainly nocturnal. It withstood heat well; it fed extensively on succulent leaves by day, probably as a source of water. At night it fed mainly on insects. Non-breeding adults had an eclipse plumage. Histology of the testes showed that the species was getting ready to breed in February; this was confirmed by data from the RAOU Nest Record Cards. Histology of the supraorbital salt glands showed that they are probably active in ionic regulation of body fluids. Behavioural evidence confirms thatPeltohyasis a plover (Charadriidae) and not a courser (Glareolidae).
