Bird beaks feeling the heat of climate change, say scientists
While the human population grapples with ways to counter the effects of climate change, Deakin University research has discovered that birds might have been working on their own solution for the past 145 years – grow bigger beaks.
The scientists, led by Dr Matthew Symonds, have discovered a pattern between increased climatic temperatures and an increase in the size of the beaks of parrot species in southern and eastern Australia.
"Birds use their beaks to keep themselves cool. Just as an elephant's ears help to act as a fan to keep the animal cooler, birds can pump blood to their highly vascularized bills, enabling them to lose excess heat when they get hot," Dr Symonds said.
