...Peter R Mawson; Rick Dawson; Denis A Saunders ABSTRACT Barn Owls Tyto alba were recorded breeding in natural nest hollows in a Wandoo Eucalyptus wandoo woodland in the northern wheatbelt of Western Australia infrequently and at low densities during the period 1969-2022. During a record cropping...

...Isabella Howard; Jenna C. H. Ridley; Wade Blanchard; Kita R. Ashman; David B. Lindenmayer; Megan L. Head; Kara N. Youngentob ABSTRACT Nest boxes are often deployed in an attempt to offset the loss of natural tree hollows following landscape disturbance (e.g., land clearing, logging and wildfire...

...Michael Guppy; Sarah Guppy; Peter Fullagar ABSTRACT The nest of a Superb Lyrebird, in a spotted gum forest on the south-east coast of Australia, was monitored for approximately 10 weeks. The nest was discovered before the egg was laid, on June 16, 2020. The egg was laid on July 7, and the chick...

...Murray V. Ellis Nest boxes have been widely used across the world to provide shelter for animal species, often to restore areas following the loss of natural tree hollows. While the microclimates of installed nest boxes have been studied, limited attention has been paid to whether microclimate...

...Michael Guppy; Sarah Guppy; David Priddel; Peter Fullagar Nest predation is the most common source of nest failure in most passerines, yet the identity of the predators is generally poorly known. Recent advances in surveillance cameras have made the identification of nest predators much easier. We...

... habitat clearance. As part of recovery plans aimed toward reintroduction to the wild, both species are part of an intensive captive breeding program being conducted at a number of institutions, including Taronga Zoo, Sydney. These honeyeaters incorporate arthropod silk into their nests, as has been...

...David Booth The nesting behaviour of two Australian freshwater turtles, the broad-shelled river turtle Chelodina expansa and the Brisbane river turtle Emydura signata are described. Both species nest during, or soon after rain. C. expansa nests exclusively during the day while E. signata...

Over eight breeding seasons, all nests were found, and sightings of multiple individuals from...

... functions. A leading hypothesis is that turtles have declined through lost recruitment caused by high nest predation by invasive foxes. The ‘fox hypothesis’ is supported by experiments showing that nest predation rates exceed 95% in many regions. Furthermore, population surveys have repeatedly found...

... of the Southern Brown Bandicoot Isoodon obesulus obesulus and Long-nosed Bandicoot Perameles nasuta eight months after a wildfire. We analysed the number of shelters, frequency of shelter use, nest size, and shelter site microhabitat. Southern Brown Bandicoots used significantly more shelters than Long-nosed...

Yellow-plumed Honeyeaters are sensitive to the effects of drought, with less nesting during dry seasons...

This study clearly demonstrates that Chelodina longicollis , Australia's most widespread turtle (1) is resilient to high levels of nest predation for sustained periods, (2) requires only periodic levels...
