Finches’ personalities ‘shown by head colour’ (BBC Nature 6June12)

Gouldian finches have different personalities depending on the colour of their heads, researchers have found.

Scientists from Liverpool John Moores University and The Royal Veterinary College investigated the “highly sociable” Australian birds.

The team set the finches a series of behavioural tests to understand the purpose of their bright appearance.

They found that red-headed finches were more aggressive, while black-headed birds were bolder and took more risks.
