The kiwi is the only bird to have its nostrils at the tip of its beak. Other birds have the nostrils higher up, usually near the base of their face. But not the kiwi. It has the second largest olfactory bulk relative to the size of its forebrain (the condor having the largest), meaning it has an exceptional sense of smell. It uses this sense of smell and these specially placed nostrils to locate food in leaf litter.
