Search Results for Foraging Resources

... events resulted in large numbers of Grey-headed Flying-foxes Pteropus poliocephalus requiring rescue and rehabilitation. Prolonged drought and intense bushfires reduced available foraging resources for the Brush-tailed Rock-wallaby Petrogale penicillata and Mountain Pygmy-possum Burramys parvus...

...David Paull; David Milledge; Phil Spark; Sally Townley; Kevin Taylor Habitats where rodents breed and congregate provide key refuge and foraging resources and as such may be important for the survival of local populations. The habitat characteristics at spring-time breeding and congregation sites...

...Catherine J. Price; Peter B. Banks ABSTRACT Despite their conspicuousness within urban environments, the ecology of commensal species is poorly understood. Urban environments are thought to provide abundant foraging and shelter resources for commensal species such as Black Rats Rattus rattus...

... of the ecology of honeyeaters is therefore basic to the conservation management of Australia's natural environments. In this paper, we describe the foraging ecology of honeyeaters in the Great Western Woodland (GWW) during the spring, comparing the use of resources between species and locations. Species...

... manoeuvres and substrates, as well as foraging heights and the plant species frequented to find food. The continued abundance and diversity of species/guilds through the winter is best explained by the variety of food resources available for birds; the complexity of foliage, bark, and ground substrates...

... and woodland birds, avian foraging behaviour, resource allocation, avian foraging guilds, biodiversity, conservation management, arthropod abundances Published: 4 August 2021 DOI: httpsdoi.org/10.7882/AZ.2021.023 Introduction In Australia s eucalypt forests and woodlands, co-habiting birds differ...

... with declines in abundances of prey and host species. Declines in abundance and breeding were probably linked to declines in food resources, although there were no consistent changes in the foraging behaviour of birds. There was a modest recovery in breeding effort and species abundances in 2010 following above...

... threatened. It is also necessary for the listing of species as threatened before extinction is inevitable. Cody (1973) considered knowledge of foraging ecology the most basic and critical part of avian biology. Information on the resources required by birds for feeding and breeding and how these differ...

... and are particularly vulnerable to loss or modification of foraging habitat and to culling by humans, which primarily affects pregnant and lactating females (Eby 1995; Tidemaun et a l . 1997; Richards and Hall 1998). Further concerns have been raised regarding competition for foraging resources from Black Flying-foxes...

... Inlet, Cairns. Birds were counted on four occasions from 1998-1999, and forty-seven bird species, representing nine foraging guilds, were recorded. Vegetation type was a strong discriminator of bird composition. I recorded a number of mangrove-obligate species (e.g. Collared Kingfisher, Mangrove Robin...

...). There are three are inappropriate cave management, reduction in maternity caves, one near Warrnambool, a second small foraging resources due to drainage of wetlands and land one near Cape Bridgewater (both in Victoria), and a third clearing, human disturbance at roosting sites, exposure near Naracoorte in SA...

... of factors including partitioning of habitat for reproductive requirements, differential use of roosts by the sexes and use of different foraging resources. The results of just single trap nights yielded striking results (Table 4). For example, 25 female Large-footed Myotis were caught on one night in early...

... as cover per se, shrub-layer plants are not used as a foraging resource by P. oralis, and consequently the habitat assessments from the two grids were pooled for analysis. Shrub-layer habitat use When information from all spooled P. oralis was combined, the shrub-layer canopy cover type with the highest...

... losses of keystone and abundant species. However, it is important to try (Baker et al. 2019; Bennett et al. 2023). As Gaston (2010; p. 154) notes, being common is rare and common species are important in shaping the world around us . Studies of resource allocation and foraging behaviour are considered...

... are observed (Cox 2019; Heathcote 2019). Foraging habitat mapping To understand the seasonal distribution of food resources, the NSW and Australian Governments commissioned a foraging habitat mapping study. This study defined the foraging habitats of the Greyheaded Flying-fox and provided a method for ranking...

... will disadvantage others. Consequently temporal and spatial habitat heterogeneity is necessary for the conservation of avian biodiversity.
