Biologists at the University of Utah analyzed 216 bird extinctions since 1500 to identify traits that could inform conservation efforts for critically endangered species. The study found that birds most at risk of extinction shared certain characteristics: they were often endemic to islands, lacked flight ability, had larger bodies, possessed sharply angled wings, and occupied specific ecological niches. These traits made them more vulnerable to environmental disruptions, highlighting the need for targeted conservation strategies.
