Scientists say they are hoping to develop a deodorant for New Zealand’s native birds to stop them falling prey to introduced predators.
New Zealand has an abundance of native bird species, including the famous kiwi, but no native land mammals, meaning introduced animals such as cats and stoats have had a devastating impact on bird numbers.
Canterbury University reseacher Jim Briskie said it appeared New Zealand birds suffered from body odour, making them an easy target for predators.
Prof. Briskie said unlike their overseas counterparts, which evolved alongside mammals, New Zealand birds emitted a strong smell when preened to produce wax to protect their feathers.
