You have surely already noticed that your bird uses its right paw or its left paw instead … So what is it really?
Sydney biologists have noticed a complete match between vision and limb use in parrots in Australia! The study involved more than 300 individuals of 16 different species.
Results : there is a correlation between the eye used to observe an object and the paw used to grasp it. The study then reveals that 47% of individuals studied use more their left eye and so their left paw for grasping against 33% individuals who go favor the right eye and right paw ! There is, however, 20% individuals who have marked ambidextrous tendencies.
Parrots are then, unlike Humans, mostly left-handed!
