Silver Eye

Silver eye.
Ready and alert
Temporary perch
Vantage for the moment

Also known as wax-eye or white-eye, Zosterops lateralis belongs to the widespread family Zosteropidae.
New Zealand possesses one species which is a relatively recent arrival in this country from Australia. Permanent invasion occurred in or before 1856, the birds obviously being carried in flocks across the Tasman Sea by one or more of the weather systems which, in these latitudes, travel in a predominantly east-west direction. By 1861 the species had established a permanent footing in the Chatham Islands. Now it has a wide distribution
throughout the country and has even reached as far north as the Kermadecs and as far south as Campbell Island. It may be found in a variety of habitats from sea level to above the tree line but it is not abundant in deep forest. Flocks form in late autumn and winter and in some years these become very common in the lowlands. Slightly smaller than the introduced house sparrow, the silvereye is olive-green above, pale chestnut below, and there is the characteristic, almost complete, ring of white feathers around the eye.
Males are slightly brighter in plumage than females. ~ Bernard
