Birds Not Impressed By Colour
Studies have shown that birds are not as impressed by colourful plumage as their human admirers usually are. A birds eye view is more colourful than that of a human; however, because of the fact that they are sensitive to a wide range of hues invisible to the human eye, their own plumage is often drab in their own view, because it lacks these colours.
The research has been published in the journal Behavioural Ecology in a joint study from the University of Cambridge and researchers in the USA. They studied the entire range of plumage pigments and compared them to the colours that birds can actually see. They found vast regions of available "colour space" visible to birds missing from their plumage. Birds were able to make only about 26 per cent to 30 per cent of the colours they were capable of seeing.
