The post-fledging dependence period, a crucial stage in developing survival skills, is a poorly studied ontogenetic phase in Australian owls. Post-fledging behaviour, development and dispersal were studied in 10 broods in six territories of the Southern Boobook Ninox boobook in Canberra, ACT during 1999–2008 using colour-banding and radio-tracking. Owlets fledged in summer (usually December–January) at […]
Masked Lapwings Vanellus miles novaehollandiae nesting in urban and peri-urban areas generate several management issues, such as their ground-based nests being vulnerable to destruction and their aggressive, defensive behaviour towards humans and pets. This paper reports on a four-year study of Masked Lapwing breeding attempts at two peri-urban sites in western Sydney, Australia. The mean […]

Many birds cannot colonize cities, but for those that can having the phenotypic plasticity to adjust to urban conditions and/or being preadapted for them is critical. Other factors potentially facilitating avian synurbanization are the capacities to dominate aggressive resource competition with established species and exploit the specific advantages of urban flocking. We investigated the foraging […]
