How do Kererus survive?
The seeds in the berries are not digested and fall to the ground in a new part of the forest in the bird droppings. If there were no kereru there would be no more karaka, tawa or taraire. The kereru needs the trees for food, and the trees need the kereru to disperse or spread their seeds. Kereru live for 5-6 years.
What are the kereru predators?
The most serious threat to the kererū comes from predators. Recent studies in several parts of the country have found that many nests produce no chicks at all. Rats, stoats, cats and possums eat their eggs and young; stoats and cats will also attack and kill adult kererū.
What is a kereru habitat?
Habitat. Kereru inhabit a wide variety of forest types: podocarp-broadleaf forest, beech forest, second growth native forest regenerating after logging, small forest remnants, and exotic plantations (especially those with an understorey and/or stream-sides of native shrubs and trees).
Do wood pigeons have predators?
Wood pigeons have many natural predators such as birds of prey, foxes and badgers, but with so many breeding pairs in the UK, this has a negligible effect on their overall population.
What do kereru get drunk on?
Kererū eats the fruit, leaves, twigs, buds, and shoots of over a hundred native, and fifty exotic, shrubs and trees. Occasionally, they gorge so heavily on ripe fruit that they become very full (or “drunk”) and have been known to fall out of trees.
Do wood pigeons get drunk?
Wood pigeons are gorging themselves on a bumper crop of summer fruit – to the point they’re getting drunk and falling from trees. Locals in South Westland are being asked to keep an eye out for the intoxicated kereru, New Zealand’s native wood pigeon, and help them sober up.
What adaptations do kererū have?
The kererū has the widest gape of any New Zealand forest bird. This enables it to swallow, digest and disperse the large fruit and seeds of the karaka, miro and tawa trees. The tūī has a long, curved beak and a fine brush-tipped tongue that enables it to extract nectar from forest tree flowers.

The parents feed each chick a protein-rich “milk”, which they secrete from their crops, adding partially-digested fruit to their diet after a couple of weeks. Chicks leave the nest at 30-45 days old, but the parents continue feeding them for at least another two weeks.
