The Australian Magpie is a medium-sized black-and-white bird found across Australia. Its back pattern varies by sex and region.
It has a sturdy body and wedge-shaped bill. Males have white on the nape, shoulders, and upper tail; females have mottled gray backs.
Researchers studied wild Western Australian Magpies in urban parklands. They played either background or plane noise to the birds under heat-stress and non-heat-stress conditions, then compared foraging and vigilance behavior.
Heat and plane noise each reduced foraging and increased vigilance. When both occurred together, the behavioral changes were greater than under either stressor alone. The experiment shows how two common features of urban environments can combine in their effects on a wild bird.
An extinction-risk assessment has not been added yet.
Where heat and noise occur together, birds may have less time available for feeding. Urban green-space planning can support magpies and other birds by retaining shaded places and quieter areas, while considering several environmental pressures together.
