Goldfinches


There are a lot of goldfinches in and around Greytown. Indeed, I think they could be the most numerous of birds around here, nothwithstanding sparrows have had something of a comeback this summer. Soon the finches will be flocking for the winter and “charms” of over a hundred goldfinches twittering about the district will be quite common. With their bright red faces and gold wing bars they flutter merrily from plant to plant, often hanging upside down to extract seeds.

The natural range of the goldfinch is Europe, North Africa, the Middle East, and Western Asia. Their commonest European name of thistlefinch has been gained because they are particularly fond of the seeds of thistles, particularly the sow thistle.

They were introduced into New Zealand in the 1860s along with other European birds and are probably now more numerous here than in Europe. They were also introduced into Argentina, Bermuda and Australia.
The goldfinch has figured very large in European folklore and the earliest English literature. The cook in Chaucer’s Canterbury tales was described as being “as merry as a goldfinch in the woods” — gaillard he was as a goldfynch in the shawe.

Because of their liking for thistles, goldfinches were adopted by Renaissance artists to symbolise the Passion of Christ. In Baroccio’s ‘Holy Family’ a goldfinch is held in the hand of St John who holds it high out of reach of an interested cat. In Cima’s ‘Madonna and Child’, a goldfinch flutters in the hand of the Christ Child.

Recently on the NZ Birding news group a birder from the UK was asking birders here if they had noticed any evolutionary changes to the birds introduced into NZ from Europe, considering that these birds have now been here for about 150 years.

It is the classic Darwinian scenario, following the story of the finches on the Galapagos Islands which were so instrumental in formulating his theory of evolution. A very small number of birds, carrying just a portion of the species genetic potential will over time change and radiate to fill the ecological niches which we may offer. Isolated from their parent birds, unlike Australian introduced birds, these birds will in time become truly our own and probably quite different from their European counterparts.

Tunnel-web spiders and golden hunting wasps

My wildlife experiences these days are pretty much confined to my backyard and a daily ramble around the village of Greytown, New Zealand.  During my daily walks, it is the birds which attract my attention:  skylarks, (“Hail to thee, blithe spirit”), goldfinches, (“gaillard he was as a goldfynch in the shawe”),  black birds, (“shouting all day at nothing in leafy dells alone”), the song thrush, greenfinch, chaffinch, dunnock, california quail, house sparrow, eastern rosella, Australian magpie, starling, yellowhammer –foreigners all. Most of them were introduced in the nineteenth century as bio-agents to control plagues of insects brought about by the wholesale destruction of the bush and the consequential severe disruption of the eco-system. I welcome them all, knowing that in the not too distant future we may be lucky to see any bird at all.  I do see the odd native bird; kotare, the kingfisher, pipiwharauroa, the shining cuckoo and its dupe ...

Of Aphis and Ants, the end of the anthropocene

Marta had been awoken as usual by their antennae softly stroking her on the inner wrist. They seemed to wait until they were sure she was awake before crawling up her arm. They stroked her arm again just inside the elbow. She suspected they were administering a local anaesthetic.  She waited with the usual sense of dread for the tiny pin pricks as they probed. There were always just three of them.  Were they the same three ants every day? She couldn't tell. They were on the large size for ants, but ants they were, although their proboscides was more mosquito like than  that of any ant.  It was over in a few minutes. They waddled off with the bags inside their legs full of her blood. They disappeared under the door.  There was no keeping them out. They could fire off acid to dissolve any lock, any door, and leave humans a pulpy heap if they resisted or tried to fight back. They always made Marta think of the ants on the rose bushes ...

Butterflies

Having developed the habit of watching out for birds, then one is also likely to observe those other beautiful creatures on the wing, butterflies. The Monarch butterflies are hard to miss as they float about our gardens, alighting on some flower or leaf, giving us time to observe and admire. They are just so voluptuous drifting about the garden before being carried off like any baggage by some male to keep sequestered. Our own endemic butterflies, the red and yellow admirals, however, are likely to be missed as they flit very quickly away before one has a chance to observe their beautiful colouring, the patterns of yellow and the red on black. Gibbs, the grandson of our most illustrious entomologist G.V. Hudson, claims the Monarch is a native, having got here under its own steam, following the plantings of the milkweeds by missionaries across the Pacific Islands. However, with their legendary ability to fly over enormous distances, they may well have arrived in NZ somwhat ea...
