The Majestic Kererū of New Zealand

The Kererū (Hemiphaga novaeseelandiae), also known as the New Zealand Pigeon, is one of the most iconic and recognizable birds native to New Zealand. Known for its large size, iridescent plumage, and important ecological role, the Kererū is a treasured species in New Zealand’s forests and gardens.

Appearance

Kererū are large pigeons, measuring up to 51 cm in length. They have a distinctive and striking appearance with iridescent green and bronze feathers on their head, neck, and wings, contrasted with a white underbelly. Their red eyes and feet add to their vivid appearance, making them easily recognizable. Both males and females share similar plumage.

Habitat and Distribution

Kererū are found throughout New Zealand, including the mainland and offshore islands. They inhabit a variety of environments, including native forests, suburban gardens, and rural farmlands. They are particularly fond of areas with abundant fruiting trees and shrubs, which provide essential food sources.

Diet

The diet of Kererū primarily consists of fruits, leaves, flowers, and buds from native trees and shrubs. They are crucial for the dispersal of seeds from large-fruited native plants, such as miro, tawa, and karaka. This makes them important for maintaining the health and regeneration of New Zealand’s forests. During times when fruit is scarce, they will also eat leaves and flowers.

Behavior and Song

Kererū are known for their slow and deliberate flight, often heard before they are seen due to the distinctive sound of their wing beats. They are generally solitary or seen in pairs, but can form small flocks when food is abundant. Kererū are relatively silent birds, but they do make soft cooing sounds and occasional loud wing claps during display flights.

Breeding

The breeding season for Kererū can extend throughout the year, but peaks from September to March. They build simple, flimsy nests of twigs in the forks of trees. The female typically lays a single egg per breeding attempt, and both parents share the incubation and feeding duties. The chicks fledge after about 30-45 days but may remain dependent on their parents for some time after.

Conservation Status

The Kererū is currently classified as “Not Threatened” but is subject to ongoing conservation efforts due to habitat loss, predation by introduced species, and occasional illegal hunting. Conservation initiatives focus on habitat restoration, predator control, and public education to ensure the continued survival of this important species.

Conclusion

The Kererū is a magnificent and vital part of New Zealand’s natural heritage. Its role in seed dispersal is crucial for the health of native forests, and its striking appearance makes it a favorite among bird enthusiasts. Protecting and preserving Kererū populations is essential for maintaining the ecological balance and natural beauty of New Zealand’s landscapes.
