New fossils reveal Australia was once home to a much greater diversity of huge eagles and vultures, which died off alongside ‘giant wombats’ and ‘marsupial lions’.
Our study found it wasn’t cafes with access to sugar-rich food that led to more miner aggression. In fact, gardens were where we recorded the highest amount of aggressive behaviour.
The heaviest bird nest ever discovered weighed more than 2,000kg. It was built by bald eagles. The tiniest nest, built by a bee hummingbird, was just over 2cm wide.
It’s still not known exactly how female birds produce such colourful and intricately-patterned eggs. But we do have some theories about the survival advantage this provides.
Spring is rapidly approaching and many birds are hunting for the best nesting sites. Competition is fierce — especially for species that nest in tree hollows.
Scientists and bureaucrats moved logistical mountains to rescue the eastern bristlebird from bushfires this year. As climate change worsens, wildlife evacuations will become more common.
When is a galah not a galah? That depends on which scientific name is attached to the Australian bird. There’s been some confusion over this, which DNA testing has finally solved.
