For long-lived birds, estimates of productivity can be effective indicators of environmental change or responses to management. Such estimates are also valuable in modelling population growth. We report estimates of nest survival for burrow-nest[...]

Recent phylogeographic studies have examined the location and timing of putative Plio-Pleistocene biogeographical barriers in moulding present-day patterns of diversity in southern Australian vertebrates. We previously investigated the divergenc[...]

The abundance of consumers and the availability of resources are often linked, and birds are known to track food resources at a variety of spatial and temporal scales. This study describes the seasonal influx of nectar-feeding birds during flowe[...]

Natural environments have been greatly transformed by human populations and activities and the responses of species to these changes vary. In human-dominated environments, birds may adopt behaviours that enable them to adjust to these novel habi[...]

Many species of birds are considered pests in rural areas modified for agricultural production. We evaluated the abundance of four species of avian pests (Eared Dove (Zenaida auriculata), Monk Parakeet (Myiopsitta monachus), Picazuro Pigeon (Pat[...]

Physiologically demanding and energetically expensive life-events, such as incubation, chick-rearing and moult, may cause a trade-off with costly immune defences and, in turn, decrease immune function. We examined innate immunity in Little Pengu[...]
