Parrots Just Like Us
Scientific evidence shows that humans are not the only species that has “handedness” i.e. – that is either right-handed or left-handed (or in some cases ambidextrous). A study published in the journal Biology Letters claims that parrots nearly all have preferences for either their left hand and left foot or right hand and right foot. The exception is the cockatiel which shows no preference. The researchers, from McQuarie University in Australia, suggest that this difference has evolved because cockatiels graze on small grass seeds that may require little coordination between the eyes and feet.
