Birds perceive 'warm' colors differently from 'cool' ones

(Duke University) Birds may not have a word for maroon. Or burnt sienna. But show a zebra finch a sunset-colored object, and she'll quickly decide whether it looks more " red " or " orange. " A new study shows that birds mentally sort the range of hues on the blue-green side of the spectrum into two categories too, but the line between them is fuzzier, perhaps because " either/or " thinking is less useful in this part of the spectrum, researchers say.
