... change is essential for the retention of healthy forest ecosystems and biodiversity. Information at the level of detail required for effective conservation management is missing for most Australian birds, including warblers and pardalotes. It is unlikely the data needed for the conservation...

...Harry F. Recher ABSTRACT Frequency of occurrence data are available for birds along a transect in Kings Park, Perth, Western Australia from 1928 to 2008. These data show a dynamic avifauna with about a third of the sixty-one bird species recorded declining in frequency since 1928, another third...

...Harry F. Recher ABSTRACT In Australia’s eucalypt forests and woodlands, co-habiting birds differ in the foraging manoeuvres or methods used to search for and take prey, the substrates and plants on which prey are found, and the heights at which foraging takes place. On the Southern Tablelands...

...Garry Daly ABSTRACT Aubrey Elliott (1910–1943), a passionate ‘bird-man’, lived in the suburb of Tapitallee on the south coast of New South Wales until 1940. During that period he and his brother, Arthur kept notes on the birds in the local area and devised a hide that was mounted on a utility...

...Michael Guppy; Anthony Overs; Sarah Guppy ABSTRACT The details of a breeding season have been investigated and described for many bird species and groups of species, but rarely for an entire breeding community. The collection of such data is the only way of quantifying the number of birds a habitat...

...Michael J. Murphy ABSTRACT The majority of studies into the response of birds to logging in Australian forests has been done in forest-dominated landscapes or relatively large forest blocks, where the surrounding landscape can ameliorate impacts. This is the first study to examine the response...

...Claire Runge; Ayesha I.T. Tulloch ABSTRACT Nomadic birds move around the landscape in complex, irregular patterns, making it difficult for conservation managers and planners to decide where and how to act to mitigate threatening processes. Because of this uncertainty, nomadic species are poorly...

...Harry F. Recher In this paper, I present data on the foraging behaviour of eucalypt forest and woodland birds at two sites on the Southern Tablelands of New South Wales during the non-breeding season (winter). The winter community was a subset of the summer community, with six guilds among 23...

...L. C. Llewellyn A total of 5618 birds (118 species) were banded in the Riverina between 1964 and 1972. A total of 3139 of these (95 species) were banded at the Inland Fisheries Research Station (IFRS) (now the Narrandera Fisheries Centre) on 629 days netting. At the IFRS 608 individual birds were...

... recorded over the 1962-78 period by other workers (A.Davies, J.Izzard, J.Hobbs, P.Wilson and other joint authors) giving a total or 319 species in the Riverina over that period. The more recent lists of the Bird Atlas I and 2 1988-2001 and the Bird Trails document up to 2011, which cover a large proportion...

..., there was less vegetative growth, and nectar production declined. As habitats became drier, fewer birds nested, although some bred and fledged young. Ground, shrub, and canopy foragers, including migrants, along with nectar-feeders declined in abundance. The numbers of raptors and cuckoos declined in line...

...Murray Ellis; Jennifer Taylor Loss and fragmentation of the native vegetation of the Central Western Plains of New South Wales was followed by declines of woodland-dependent species. Drought is likely to have further suppressed many animal populations. Here we report on changes in woodland bird...

.... We conclude that the data are consistent with the hypothesis that the Gouldian Finch suffered a major population decline in the Kimberley area in the late 1970s. We also discuss a range of “sustainable conservation” issues related to the harvest of wild birds for the avicultural trade and suggest...

...Allan Keast Over the last 50 years major areas of bird habitat have been lost from the County of Cumberland. Included are the major saltmarshes and freshwater swamps from the western side of Botany Bay; the tall forests of the Upper North Shore and the woodlands of the Cumberland Plain between...

...Rodney Kavanagh; Matthew Stanton A regional survey of 253 forest sites on the southwestern slopes and adjacent highlands of New South Wales recorded a total of 530 animals from five species of nocturnal forest birds and nine species of arboreal marsupials. One additional species, the Squirrel...

... South Wales on the occurrence of birds in woodlands that have been highly fragmented and structurally altered over the last 150 years. The species composition of the region is still very similar to that recorded 3 decades earlier but many small insectivorous and nectivorous woodland birds are rare...

...M. Guppy; A. Overs; S Guppy; A. O. Nicholls We document here the effects of an unusual temperature event related to a site in South East NSW that is the subject of a longitudinal study of the breeding biology of woodland birds. In the three breeding seasons before the 2009-10 season we recorded...
