Silver-eye, wax-eye or white-eye


Zosterops lateralis, the little silver-eye, is not so numerous in the Wairarapa as it is up north where huge flocks congregate in the winter and descend upon berry producing trees and shrubs in their hoards. Hurrying from tree to tree, from one garden to another, with a continuous, noisy twitter, or uttering short plaintive notes, they set about distributing seeds, mindless as to what is is they are casting about, and with no concern at all as to whether the seeds are native or obnoxious. Poroporo keeps on sprouting in my garden here, undoubtedly spread by silver-eyes.

Now that the house sparrow numbers are very much in decline, the silver-eye is probably New Zealand's most numerous bird, far out numbering the more obvious starlings which tend to get the blame for the silver-eyes' crimes against orchardists. Silver-eyes have a particular fondness for fruit. They happily eat their way through a wide range of fruits, including apples, kiwi fruit, feijoas, figs, grapes, pears and persimmons. Their pointed beaks can break the skin of fruit more readily than other birds, and once the skin is broken it allows other birds the opportunity to feast. But as Buller said, “It far more than compensates for this petty pilfering by the wholesale war it carries on against the various insects that affect our fruit trees and vegetables”.

The silver-eye is a small olive–green bird with white rings around the eyes. They have a fine tapered bill and a brush tipped tongue like the Tui and Korimako, the bellbird, for drinking nectar. There are many species in Africa, southern Asia, and the south western Pacific, but it is the Tasmanian sub–Australian species which migrates to the eastern states of the Australian mainland in winter which colonised New Zealand. They were recorded in New Zealand as early as 1832 but it was not until 1856 that they arrived in very large numbers. It is assumed that a storm caught a migrating flock in Australia and diverted them here. The Maori name, Tauhou, means “stranger”.
Their success as a species has probably a lot to do with their varied diet which is mainly comprised of insects, fruit and nectar, but they will also readily take fat, cooked meat, bread and sugar water from bird tables.
They are delightful, busy little birds and are strongly territorial and are often seen fluttering their wings aggressively at another bird. I have seen them cuddling up in pairs on a branch busy preening and feeding each other. With their white ringed eyes set close together, they look so much like clowns. And then to see them with a bright red cotoneaster berry in their beaks, the picture is complete.

Turkeys and the domestic contract between animals and farmers

I suppose one should be forgiven for thinking about turkeys at Thanksgiving or Christmas but I wonder how many realise how much the wild turkey is part of our rural landscape, so much so that Americans now come out here to the Bay of Plenty to hunt them. When I first came to the Bay of Plenty, I was much taken by the mobs of wild turkeys wandering about the district. I was especially interested in those wandering about my neighbours’ farms but soon learned that the turkeys were not so wild that my neighbour’s did not have a propriety interest in them. Turkeys were introduced to New Zealand around the 1890s. In those days, until around the 1950s, most farms raised a few pigs and had a mob of turkeys along with “chooks” and ducks to give a greater self-sufficiency than is apparent on most farms today. The turkeys were half domesticated and half wild in that the mobs were allowed to roam free but were occasionally fed maize. The chore of rounding up the mob to feed them usually fell to the …

A Murder of Rooks

From Southland to Northland, Regional Councils around the country are once again putting out the call for sightings of rooks, Corvis frugilegus, in their efforts to exterminate them.
The rook is a minor agricultural pest, on a par with the yellowhammer, so how did this bird become a target for extermination rather than control? How did this bird become an unwanted organism under the Biosecurity Act?
The rook is a black, hoarse–voiced bird about the size of a magpie which was brought to New Zealand from Britain between 1862 and 1874 to help control agricultural pests. Unlike many other European birds introduced at the same time, rooks spread very slowly at first. Even as late as 1970, they were largely confined to parts of the Hawke’s Bay, Manawatu, southern Wairarapa and Canterbury.
In the 1971 rooks were declared an agricultural pest in the Hawke’s Bay, largely because of the damage done to emerging crops.  Something like 35,000 thousand were shot, probably about half the population. Co…

They don't know who we are

They Don't Know Who We Are
I was sitting over the kitchen table, drinking tea and smoking. The back door was open but no matter how hard I listened I could never hear him coming until he kicked off his boots at the back door. “Sitting in the dark again,” he said as he came in and turned on the light. We blinked.
I poured him a cup of tea and lit another cigarette, tailor made. He sat down and rolled a cigarette. Those were the days when we all smoked, chain smoked.
“There are a couple of deer up there,” he said after he had lit his cigarette.   “Yeah,” I said. The pause was long and drawn out. “A hind and her fawn I figure.”
We drank our tea and smoked our cigarettes. I let him come to it in his own time.
“I suppose I should shoot them, before someone else does.”
I shrugged and shook my head.  I had seen it all before with hunters. Once we get past the age of 30 the old thrill of the hunt goes, and we get all sentimental, become bird watchers and photographers. The same with fishermen. T…
