I planted some teasel seed abot 20 years ago and they've been seeding themselves around the garden ever since - so the goldfinches don't get all the seeds.Philhttps://www.blogger.com/profile/15609107148344256875noreply@blogger.comtag:blogger.com,1999:blog-4998479738444661160.post-4347025508226852132009-09-13T16:50:44.976+00:002009-09-13T16:50:44.976+00:00Hi Squirrel, The difference in beak size was new t...Hi Squirrel, The difference in beak size was new to me too. The breeding for bird resistance using the long bristles is in pearl millet, rather than thistles, but the principle is the same!Philhttps://www.blogger.com/profile/15609107148344256875noreply@blogger.comtag:blogger.com,1999:blog-4998479738444661160.post-29166966995018622582009-09-10T08:31:49.910+00:002009-09-10T08:31:49.910+00:00Very interesting Phil.

If I can get some to grow in the garden maybe next year I can take some video of the local Goldfinches at work.Midmarsh Johnhttps://www.blogger.com/profile/10980417659811194899noreply@blogger.comtag:blogger.com,1999:blog-4998479738444661160.post-1786947966743741892009-09-09T18:50:02.914+00:002009-09-09T18:50:02.914+00:00Something else I never knew!

I've just looked this up in the New Naturalist volume about finches which confirms that the males are slightly larger birds than the females and have a bill about 10% longer (about a millimetre or two). Females, as a result, prefer other plants than teasels which they find hard to reach. <br /><br />The graded variations in bill design of all the finches in Europe, from the crunchers of the hawfinch to the tweezers of the goldfinch means that no two species have exactly the same feeding preferences and the group as a whole neatly divides out the available seed types.<br /><br />A further split then occurs within some species, like the goldfinch, between males and females. Maybe there is an advantage here in that if the 2 parents are able to utilise a broader range of seeds between them they have a better chance of feeding their young if one type of plant has a bad year??<br /><br />Incidentally, I see that man Darwin was on the case again, observing this feeding difference in 1857!<br /><br />As for the teasel - well it hasn't caught up with the goldfinch yet I suppose - evolutionary work in progress.....Nyctalushttps://www.blogger.com/profile/03529729794764990304noreply@blogger.comtag:blogger.com,1999:blog-4998479738444661160.post-580182163466271882009-09-09T06:20:40.444+00:002009-09-09T06:20:40.444+00:00That is a stunning picture Phil; backlit on black ...That is a stunning picture Phil; backlit on black background, perfect.<br />Interesting about the beak size for telling the sexes apart.
