LONDON: Birds have evolved larger brains to cope in harsh environments where the tasks of finding food, evading predators and finding shelter are more demanding, say scientists who predict that smart creatures may cope better with climate change than less brainy ones. Researchers, including those from University of Bath in the UK, used data from over 1,200 bird species to test whether large brains relative to body size are more prevalent in a harsh and unpredictable climate than smaller ones. They found that birds that live in highly seasonal environments such as in polar regions have significantly larger brains than...
