The other two check on the kiwi. The mother kiwi needs to recover after laying eggs. To become an Operation Nestegg helper you need to learn how to hold the kiwi carefully. It is easier to track kiwis when they have a transmitter. When kiwis don't have a transmitter they come close to the recorded sounds of other kiwis at nighttime.
Staff use an aeroplane to find kiwis sometimes.
One kiwi that was tracked had travelled about six kilometres in one week. In summer they are found in vegetation and toi toi because it's too hot in their burrows. To determine what type of predator is around the staff use teeth marks, hair and droppings. Farmers cut down trees so there are fewer homes for the kiwi. Kiwis were first released in Tongariro National Park in 1997.
