A pair of small spotted kiwis may dig up to 100 burrows in their territory and use them as shelters, often changing homes daily. They do not leave their burrows during the day, except in dangerous situations. They usually come out at night. Foraging takes place about 30 minutes after sunset. It is dominated by insects, snails, spiders, worms, shrimp, and can even eat small lizards and mice, as well as fruit and berries that fall on the ground. The nostrils of the kiwi bird are not at the base of the beak like the thrush or the swallow, but at the tip of the mouth. Its sense of smell is very good, and it can smell the worm more than ten centimeters underground, and then dig it up with its claws or mouth. In addition, its mouth has an unexpected function - when it needs to rest, the mouth can be used as a third leg, like a tripod to support the body, easy and stable.
