Relationship patterns among flightless stick insects suggest that birds disperse the eggs after eating gravid females. Lab experiments previously suggested the possibility, but a new genetic analysis of natural populations in Japan by Kobe University researchers now supports the idea.
Rising global temperatures are making it harder for birds to know when it's spring and time to breed according to a new study published in Proceedings of the National Academy of Sciences.
A new study by The Australian National University (ANU) researchers lifts the lid on more than a half-century of evidence outlining the impact of climate change on more than 60 distinct bird species.
