Silvereye

The Silvereye, known scientifically as Zosterops lateralis, is a diminutive and charming passerine bird, weighing a mere 10 grams and measuring 11 to 13 centimeters in length. Its most striking feature is the prominent white ring encircling its eye, which gives rise to its name. The plumage varies among subspecies, but typically includes olive-green wings, a back that may be grey or olive-green, a lighter throat of yellow or grey, flanks ranging from chestnut to pale buff, and an undertail that can be either white or yellow.

Identification Tips

To identify the Silvereye, look for the distinctive white eye-ring and small size. The bird's back and wings are generally olive-green, and the throat is lighter in color. The flanks and undertail vary in color among subspecies, which can be helpful in distinguishing them, particularly where their ranges overlap.

Habitat

The Silvereye is a versatile species, inhabiting a range of vegetated areas, excluding open grasslands. Its preferred habitats include forests, scrubs, horticultural blocks, and urban gardens.

Distribution

Native to Australia, New Zealand, and the south-west Pacific islands, the Silvereye is commonly found in the fertile regions of south-west and south-east Australia, including Tasmania and the Bass Strait islands, as well as the tropical coastal zones of Queensland.

Behaviour

Silvereyes are known for their breeding habits in the spring and early summer, crafting delicate nests from grass, moss, hair, and spiderweb. They lay two to four pale blue eggs per clutch and may raise multiple broods in a season. Post-breeding, many Australian Silvereyes migrate northward, with some populations undertaking remarkable journeys across the Bass Strait. They are omnivorous, feeding on insects, berries, fruit, and nectar, and are known to visit bird tables in winter when food is scarce.

Song & Calls

The Silvereye communicates with a variety of calls and is particularly vocal when foraging in flocks.

Breeding

Breeding occurs mainly between September and December. The Silvereye constructs a tiny cup-shaped nest in the outer branches of small trees or shrubs, where it lays its pale blue eggs. The young fledge after about 10 days from hatching and gain independence at 3 weeks of age.

Similar Species

While the Silvereye is unique in its eye-ring, it can be confused with other members of the Zosterops genus, which share similar features but may differ in eye-ring color and plumage details.

Diet and Feeding

Silvereyes have an omnivorous diet that includes insects, fruit, and nectar. They are known to frequent orchards and gardens, where they can become pests by feeding on a variety of cultivated fruits.

Conservation status

The Silvereye is classified as Least Concern by the IUCN, indicating that it is not currently at significant risk of extinction in the wild.
