Ian’s Bird of the Week – European Goldfinch ~ by Ian Montgomery

Newsletter – 1/21/15

Last week I mentioned that the Zebra Finch was an Estrildid or Grass Finch (family Estrildidae) without exploring the significance of this, so here is a taxonomically quite different finch, the European Goldfinch (family Fringillidae), to continue the subject. Choosing it was prompted by an email from some English friends of mine currently in New Zealand who expressed disappointment that most of the birds seemed to be ones introduced from the British Isles, naming in particular the Goldfinch. So here is a photo of one that I took in its native habitat, when staying with these friends in 2001 on Alderney one of the smaller inhabited Channel Islands off the coast of France.

It was introduced to Australia as well in the 1860s and is quite widespread in the southeastern mainland and on Tasmania. It’s an attractive bird with a canary-like song and like the Zebra Finch a popular cage bird. So it’s not surprising that homesick settlers introduced it. It does well in farmland, parks and gardens but not in native vegetation.

European Goldfinch (Carduelis carduelis) Male by IanThe sex of adult Goldfinches can be told from their plumage, even though they are very similar and most field guides don’t make the distinction. It’s a bit like those Spot the Difference puzzles, so here, second photo, is an Irish male to compare with the female in the first. The pale cheeks on the female are buff, those on the male white. The red bib on the female is rounded, on the male more rectangular. The female usually has a complete buff breast band; the male just has buff breast patches separate by white. The male is also whiter underneath. There are other subtle differences not apparent in these photos such as the amount of white on the tail.

PAS-Frin European Goldfinch (Carduelis carduelis) Juvenile by IanYou can tell from their stout conical bills that they are seed-eaters, and any such vaguely sparrow-like bird is likely to be called a ‘finch’. In temperate zones seeds are available mainly in spring and autumn, so dietary versatility is needed. The male is chomping its way through the buds and flowers of Hawthorn and Goldfinches will also feed on invertebrates. Their favourite food is the seeds of thistles and their, by finch standards, relatively pointed bills are adapted to picking out seeds from among thorns, like the juvenile bird in the third photo in autumn. Its plumage, apart from the black and yellow wings, is mainly brown and streaked with no red or black on the head, and almost pipit-like.

The juveniles acquire the adult plumage during the first autumn moult, and the rather scruffy individual in the fourth photo is in mid-transition. This photo shows the very pointed bill, even if the owner is looking a bit doubtful about the even scruffier thistle head.

European Goldfinch (Carduelis carduelis) Juvenile by IanGetting around to the taxonomy at last, the various groups of finch-like birds have caused and still cause avian taxonomists many headaches, and I don’t want to trigger any more here. It is sufficient to say that the approximately 700 global species of finch-like birds belong to several separate lineages, currently separated at the level of family.

The Fringillidae to which the Goldfinch belongs, sometimes called the ‘true’ finches (by the Europeans of course) have an almost global distribution but are completely absent, naturally, from Australasia. The Estrildidae, which include all the native Australian grass finches, occur only in Africa, southern and southeast Asia and Australasia (but not New Zealand).

The African members belong to a group called Waxbills, the Asian ones are mainly Munias or Mannikins and the grass finches are predominantly Australian. The Estrildids occur mainly in tropical or sub-tropical regions, and only in Australia have some Firetails ventured into cooler areas: notably the Red-eared Firetail in SW Western Australia and the Beautiful Firetail in the SE mainland and Tasmania.

I’m in danger of getting carried away here, so I’ll stop. Here are some links if you want to explore their photos further: FringillidaeEstrildidae and I haven’t even mentioned the other finch-like birds such as the Sparrows  Buntings and New World SparrowsNew World OriolesWeaversTanagersCardinals

Lee’s Addition:

they and every beast after its kind, all cattle after their kind, every creeping thing that creeps on the earth after its kind, and every bird after its kind, every bird of every sort. And they went into the ark to Noah, two by two, of all flesh in which is the breath of life. (Genesis 7:14-15 NKJV)
