How does a kiwi bird lay its eggs?

Answer 1

Female kiwi lay their first egg when they are 3-5 years old. Males reach reproductive age at 18 months, but in their native habitat, they tend not to breed until they older. Breeding season begins in June, the New Zealand winter, and continues through to about March of the following year.

Kiwi dig a burrow for the egg, or find a pre-existing burrow, several months before it is laid. Three weeks after mating, the female lays an egg which is about 6 times the size of an egg from another bird of similar size. Just before the egg is laid, it makes up 15-20% of the kiwi's body weight, and takes up so much room that the female is unable to eat because there is no room in her stomach.

Answer 2

Kiwi lay their eggs in a nest.

To make its nest, the kiwi digs a burrow in the ground, or takes over a pre-existing burrow, often in slopes. The nest is then lined with grass, leaves and moss. The kiwi may camouflage the entrance by dragging leaves and sticks across, once they are inside.

Answer 3

While both male and female kiwi share the incubation of the egg, once it hatches they do very little to raise the chick.

The chick hatches with its eyes fully open, meaning it is well developed and able to fend for itself almost immediately. Initially, it feeds on a yolk sac which also prevents the baby chick from moving about the nest, but this is mostly absorbed after a couple of days. The chick then begins to feed on tiny pebbles and twigs which are stored in its gizzard to help with food digestion once it starts eating real food.

Depending on the species, chicks are old enough to leave the parents' territory when they are 4-6 weeks old. (Southern Tokoeka may stay with the parent for up to 5 years.) Unlike their nocturnal parents, the chicks feed both day and night, making them more susceptible to predators. It is believed that 95% of young chicks do not survive past their first six months.

Answer 4

Kiwi dig a burrow for the egg, or find a pre-existing burrow, several months before it is laid. Three weeks after mating, the female lays an egg which is about 6 times the size of an egg from another bird of similar size.

Both male and female kiwi incubate the egg. Male kiwi develop a bare patch on their abdomen, which is the "brood patch" - a section that is used to keep the egg warm. It takes 70-80 days for the eggs to incubate.

Answer 5

Kiwi are not born. Being birds, they are hatched from eggs.

Kiwis dig a burrow for the egg, or find a pre-existing burrow, several months before it is laid. Three weeks after mating, the female lays an egg which is about 6 times the size of an egg from another bird of similar size. Male kiwis incubate the egg, and another egg may already be developing in the female, to be laid in another three weeks' time.

Hatching may take up to three days. The chick hatches with its eyes fully open. Initially, it feeds on a yolk sac which also prevents the baby chick from moving about the nest, but this is mostly absorbed after a couple of days. The chick then begins to feed on tiny pebbles and twigs which are stored in its gizzard to help with food digestion once it starts eating real food. Depending on the species, chicks are old enough to leave the parents' territory when they are 4-6 weeks old. (Southern Tokoeka may stay with the parent for up to 5 years.)
