Blue­berry-bee break­down, flu­o­resc­ing puffins, bel­uga cul­ture and more

Jamie Dun­ning tells the CBC how he found that the beaks of At­lantic puffins are flu­o­res­cent. The Bri­tish or­nithol­o­gist made the discovery when he shone a UV light on a puf­fin car­cass and parts of the bird’s beak lit up. Dun­ning told CBC that the flu­o­res­cence had some use but that he wasn’t sure what that use might be. “The bill of a puf­fin is forged by gen­er­a­tions ... of sex­ual se­lec­tion,” he said. “There’s a lot go­ing on there. That’s why it’s so colour­ful and pretty.”
