Diet

The diet of Silvereyes is varied, consisting of insects, fruits, and nectar. They play a significant role in pollination and seed dispersal, especially for native plants. In gardens, they are often seen feeding on berries and small fruits. During the winter months, they may also visit bird feeders for additional food sources.

Behavior and Song

Silvereyes are social birds, often seen in flocks, especially during the non-breeding season. They are active and agile, constantly flitting about in search of food. Their song is a pleasant series of high-pitched, warbling notes. They also communicate with a variety of calls and chirps, adding to the vibrant soundscape of their habitats.

Breeding

The breeding season for Silvereyes in New Zealand typically runs from September to February. They build small, cup-shaped nests in trees or shrubs, often hidden among dense foliage. The female lays 2-4 eggs per clutch, and both parents share the duties of incubation and feeding the chicks. Silvereyes are known to be attentive and protective parents.
