UK researchers have shown that highly sociable Australian birds, called Gouldian finches, have different personalities according to the color of their heads. <\/p>\n
The team, led by Leah Williams and Dr. Claudia Mettke-Hofmann from Liverpool John Moores University, found that red-headed birds have aggressive tendencies, while those with black heads are bold and take more risks than their peers. <\/p>\n
This is only the second time researchers have demonstrated such a strong link between personality and color. The only other study showed that dark, male Hermanns tortoises are both more aggressive and bolder than paler males. <\/p>\n
Williams studied the birds as part of her PhD project. She said: <\/p>\n
We think that head color is used as a signal of personality to other birds in the flock, so they know who to associate with. <\/p>\n
Scientists first noticed a link between animals different colors and various aspects of their behavior such as aggression, sexual behavior and predator-avoidance tactics in the early 90s. Red, for example, has long been associated with aggression in cichlids, other birds, reptiles, primates and even us. <\/p>\n
But individual behaviors like aggression can only be called personality if repeatable over long periods of time. Williams said: <\/p>\n
Earlier studies didnt look to see if these behaviors are aspects of these animals personalities, because they didnt repeat them multiple times. <\/p>\n
So Williams and animal personality expert Mettke-Hofmann teamed up with Dr. Andrew King from The Royal Veterinary College to find out if color defines personality in the endangered Gouldian finch. Williams explained: <\/p>\n
We decided to look at these finches, because an Australian study had revealed that the red-headed ones are more aggressive, with red-heads dominant over black-headed finches. <\/p>\n<\/p>\n
