Silvereye

Silvereyes breed in spring and early summer (mainly between September and December), making a tiny cup of grass, moss, hair, spiderweb, and thistledown, suspended from a branch fork in the outer reaches of small trees or shrubs. They lay two to four pale blue eggs, and two (or sometimes three) broods may be raised during each breeding season. The eggs hatch after about 11 days, and the young fledge after another 10 days. The juveniles are independent at 3 weeks and able to breed at 9 months. In late summer silvereyes gather into flocks and many Australian birds migrate, making their way north along the coast and ranges, foraging busily during the day with much calling and quick movement through the shrubbery, then flying long distances through the night. Most of the Tasmanian population crosses the Bass Strait (an astonishing feat for 12 cm birds weighing only a few grams) and disperses into Victoria, New South Wales, and south-eastern Queensland. The populations of these areas tend to head further north; while the northern-most birds remain resident all year round. In western Australia they have been recorded moving between the mainland and offshore islands. Silvereyes are omnivorous with a diet that includes insects, berries, fruit and nectar. In New Zealand they take fruit from native trees including kahikatea, and rimu. When food is scarce in winter they will take a wide variety of foods from bird tables, ranging from sugar water through bread and cooked meats, to solid lumps of fat.

The silvereye is native to Australia, New Zealand and the south-west Pacific islands of Lord Howe, New Caledonia, Loyalty Islands, Vanuatu, and Fiji. It is common to abundant throughout the relatively fertile south-west and south-east parts of Australia (including Tasmania and the Bass Strait islands), and through the well-watered coastal zone of tropical Queensland, including Cape York Peninsula The silvereye is liable to be found in any vegetated area, apart from open grasslands, within its distribution range, including forest, scrub, horticultural blocks and urban gardens.
