Yellowhammer - Emberiza Citrinella
The yellowhammer (Emberiza citrinella) is a passerine bird in the bunting family that is native to Eurasia and has been introduced to New Zealand and Australia. Most European birds remain in the breeding range year-round, but the eastern subspecies is partially migratory, with much of the population wintering further south. The male yellowhammer has a bright yellow head, streaked brown back, chestnut rump and yellow underparts. Other plumages are duller versions of the same pattern. The yellowhammer is common in open areas with some shrubs or trees, and forms small flocks in winter. Its song has a rhythm like "A little bit of bread and no cheese". The song is very similar to that of its closest relative, the pine bunting, with which it interbreeds.
Yellowhammer males learn their songs from their fathers, and over the course of time regional dialects have developed, with minor differences to the conclusion of the basic song; all are mutually recognised by birds from different areas. Each male has an individual repertoire of song variants within its regional dialect; females tend to mate with males that share their dialect, and prefer those with the largest repertoires.
The pine bunting and yellowhammer are so closely related that each responds to the other's song. The male yellowhammer's song is more attractive to females, and is one reason for the dominance of that species where the ranges overlap.
Yellowhammers of the British and Irish race, E. c. caliginosa were introduced to New Zealand by local acclimatisation societies in 1862, and soon spread over the main islands. They sometimes visit New Zealand's subantarctic islands, although rarely staying to breed, and have reached Australia's Lord Howe Island on a number of occasions. At the beginning of the 20th century, this bunting was seen as a serious agricultural pest in its adopted country.
Populations of yellowhammer have also been introduced to the Falkland Islands, and South Africa.
The yellowhammer is a bird of dry open country, preferably with a range of vegetation types and some trees from which to sing. It is absent from urban areas, forests and wetlands. Probably originally found at forest edges and large clearing, it has benefited from traditional agriculture, which created extensive open areas with hedges and clumps of trees.
Populations have declined in recent decades in western Europe, including the British Isles, Belgium, the Netherlands, Austria and Italy. The yellowhammer is a red-list (severely declining) species in Ireland and the UK In eastern Europe, numbers appear to be stable, although the trend in Russia is unknown. Changes to agricultural practices are thought to be responsible for reduced breeding densities. The introduced population in New Zealand has been very successful, with breeding densities much higher than in the UK.
Groynes reduce longshore transport by trapping beach material and causing the beach orientation to change relative to the dominant wave directions. They mainly influence bedload transport and are most effective on shingle or gravel beaches. Sand is carried in temporary suspension during higher energy wave or current conditions and will therefore tend to be carried over or around any cross-shore structures. Groynes can also be used successfully in estuaries to alter nearshore tidal flow patterns.

Nuthatch - Sitta europaea
The Eurasian nuthatch or wood nuthatch (Sitta europaea) is a small passerine bird found throughout temperate Asia and in Europe, where its name is the nuthatch. Like other nuthatches, it is a short-tailed bird with a long bill, blue-grey upperparts and a black eye-stripe. It is a vocal bird with a repeated loud dwip call. There are more than 20 subspecies in three main groups; birds in the west of the range have orange-buff underparts and a white throat, those in Russia have whitish underparts, and those in the Far East have a similar appearance to European birds, but lack the white throat.
The preferred habitat is mature deciduous or mixed woodland with large, old trees, preferably oak. Pairs hold permanent territories, and nest in tree holes, usually old woodpecker nests, but sometimes natural cavities. If the entrance to the hole is too large, the female plasters it with mud to reduce its size, and often coats the inside of the cavity too. The 6–9 red-speckled white eggs are laid on a deep base of pine or other wood chips.
The Eurasian nuthatch eats mainly insects, particularly caterpillars and beetles, although in autumn and winter its diet is supplemented with nuts and seeds. The young are fed mainly on insects, with some seeds, food items mainly being found on tree trunks and large branches. The nuthatch can forage when descending trees head first, as well as when climbing. It readily visits bird tables, eating fatty man-made food items as well as seeds. It is an inveterate hoarder, storing food year-round. Its main natural predator is the Eurasian sparrowhawk.
It breeds throughout England and Wales and has recently began to breed in southern Scotland. It is a resident, with birds seldom travelling far from the woods where they hatch.

GÉNÉRATION
En hommage à Florence, ma petite-fille, qui m’a spontanément proposé le titre de cette image.
__________
Sur ces rivages bordés d’infini, un père initie son jeune fils à l’art de la pêche en eau peu profonde. Au premier abord, on pourrait croire qu’il s’agit d’une simple scène de pêche, pourtant…
Dans nos sociétés, l’idée de génération est souvent réduite à une opposition statique entre le passé et l’avenir, entre l’ancien et le nouveau. Je crois plutôt qu’il faut y voir un mouvement, un mouvement continu de transmission et d’évolution des connaissances et des mentalités humaines. En somme, cette transmission, notamment par la filiation, permets à l’originel de rester original et de poursuivre l’aventure humaine. * Ce que nous appelons « l’avenir » est, en fait, le résultat de l’interaction et de la transmission par toutes les générations. **
_________
Ici, sur ces rivages bien en retrait des mondes utopiques qui alimentent la fureur de nos sociétés, le père et le fils renouent avec la patience et la modestie fondamentale de l’existence des êtres. Et aussi avec l’enchantement originel devant la beauté et le mystère de notre monde.
La pêche aura été un bon prétexte pour cela.

GENERATION
In honor of Florence, my granddaughter, who spontaneously suggested the title of this image.
__________
On these shores bordered by infinity, a father introduces his young son to the art of shallow-water fishing. At first glance, one might think this is a simple fishing scene, yet...
In our societies, the idea of generation is often reduced to a static opposition between past and future, between old and new. Instead, it should be seen as a movement, a continuous movement of transfer and evolution of knowledge and human mentalities. In short, this transfer, particularly through filiations (kinship), allows the original to remain original and to continue the human adventure.* What we call the future is, in fact, the result of all these generations interacting.
._________
Here, on these shores far removed from the utopian worlds that fuel the fury of our societies, father and son reconnect with the patience and fundamental modesty of being. Also with the original enchantment in front of the beauty and mystery of our world.
Fishing was a good excuse for this.

day 2 of the monsoons. At least we don't have the wind today. The dog keeps whining to go out, then puts her nose out of the door and comes straight back in. So looks like a day to catch up on some paperwork - whoopeeeee!
A fence I used once before. I use it again to christen a new lens, and because the fence pickings ain't so good in our neighborhood. Is anyone running fence tours?
HFF to all: Looking forward to seeing everyone's handiwork.
Here I am standing on the edge of Lake Michigan during a polar vortex. The wind and blowing snow made it nearly impossible to get one shot without snow completely covering my lens. But somehow I managed to get a few. The sun was trying to shine thru the clouds at sunset. Snow squalls come and go making a very dramatic stormy feel to it.

Roasted Chicken with Cabbage and Prunes
Coq au chou et aux pruneaux
(6 servings)
1/2 cup plus 4 tablespoons extra virgin olive oil, divided
16 pearl onions, peeled
5 carrots, peeled and cut into 2-inch pieces
4 celery stalks, cut into 2-inch pieces
6 cloves of garlic, separated and peeled
salt, to taste
3/4 teaspoon ground black pepper, divided
1 (4-5 lb) chicken, rinsed and patted dry
1 tablespoon fresh parsley, chopped
2 teaspoons dried rosemary, crushed
1 teaspoon dried thyme
1 tablespoon lemon zest
1 1/3 cup pitted prunes
1 very small green cabbage, cored and quartered
1/2 cup wine
1 cup chicken stock
Preheat oven to 450F. Heat 2 tablespoons of the olive oil in a large, heavy skillet over medium-high heat. Add the onions, carrots, celery, garlic cloves, and ¼ teaspoon pepper, and cook, stirring occasionally, for 10 minutes. When the vegetables are caramelized, spoon them along the sides of a large roasting pan and set it aside – or place in a romertopf.
Reduce the burner heat slightly and allow the pan to cool a bit.
Add 2 tablespoons oil to pan and return the pan to medium-high heat. Season the prepared chicken, and brown it in the hot oil (the chicken will not brown when baked.) Transfer the chicken to the center of the roasting pan where you have added the vegetables, pour the pan juices on top of it and rub it with the parsley, rosemary, thyme, and lemon zest.
Add the wine to the skillet and deglaze, scraping up any browned bits from the pan. After the wine has simmered for 30 seconds, add the chicken stock and heat through. Pour the wine sauce over the chicken and place the prunes and cabbage on the caramelized vegetables. Cover the roasting pan with a lid or tightly sealed foil and roast in the preheated oven for 60-70 minutes.
Serve with steamed potatoes.
If you look at the Google Street View of Ulm, you'll find this house as it was in 2014. The house is well-maintained, with an American flag flying on the porch. The yard is filled with a happy and vibrant selection of plants, and decorated with various knickknacks and bird baths. But on this rainy day in 2023 the house was abandoned. The yard was overgrown with brown weeds, with a crooked "Price Reduced" sign nearly hidden by a bush. I don't know what happened here, but we can guess. I can easily imagine a scenario, where the original owners were elderly, but they loved and dedicated their lives to this house and its yard. But when they sadly passed on, and there was no one to take care of the house or the property. It was put up for sale, but there were no takers. And then time passed along, as it always does.
Reduced to the essentials. Concrete, branches, light.

Minimalismus im Winterlicht
Reduktion auf das Wesentliche. Beton, Zweige, Licht.
Einen fliegenden Bussard zu fotografieren gelingt noch relativ leicht. Allerdings möchte man ja nicht einfach nur senkrecht in den Himmel schauen wo der Greifvogel aussieht wie der Drachen aus Kindertagen. Die meisten Menschen finden andere Perspektiven attraktiver. Bei dieser Aufnahme flog der Bussard zwar auch in 15-20m Höhe aber ich stand seitlich und der Aufnahmewinkel mit dem Teleobjektiv war flacher, so dass man den Bussard mehr im Profil sieht. Mir gefällt diese Perspektive besser als nur ein "Bauchfoto".
Tech. Detail: Seit einigen Monaten drehe ich nicht mehr selber am Farbregler, sondern verwende für meine Bilder nur noch die Farbprofile, die Canon in meine Kamera eingebaut hat. Meist verwende ich dann "Landschaft" oder "Portrait" als Bildstil. Das Licht bei dieser Aufnahme war jedoch so knallig, dass ich hier "Standard" verwendet habe, damit der Farbeindruck des Gefieders nicht unrealistisch "bunt" ist. Die einzige weitere Anpassung im Bereich Farbe war dann, dass ich Grün zurücknehmen musste weil der Bussard über einer grünen Wiese flog und von unten grün angeleuchtet wurde. Man sieht es noch aber es dominiert nicht mehr.
Um den fliegenden Bussard besonders detailreich sehen zu können, drückt die Tasten l (kleines L) und F11. Beim vergrößern nur durch Anklicken gehen euch viele Details verloren.
Photographing a flying buzzard is relatively easy. However, you don't just want to look straight up into the sky where the bird of prey looks like the kite from childhood. Most people find other perspectives more attractive. In this shot, the buzzard was also flying at a height of 15-20m, but I was standing on the side and the angle of the shot with the telephoto lens was flatter, so that you can see the buzzard more in profile. I like this perspective better than just a "belly photo".
tech Detail: For a few months now, I've only been using the colour profiles that Canon built into my camera for my pictures. I usually use the "Landscape" or "Portrait" picture style. However, the light in this shot was so bright that I had to use "Standard" so that the colour impression of the plumage is not unrealistically "colourful". The only other adjustment in the colour area was that I had to reduce the green because the buzzard was flying over a green meadow and was being illuminated in green from below. You can still see it, but is does not dominate the impression.
To view this picture with the best resolution in full screen press the "l" (small L) and F11 keys. When enlarging the pic by just mouse clicking you lose quality. Enjoy!
This picture was taken with the Leica Q3 at an autumn afternoon at Großer Ahornboden. Behind the valley with the colorful trees we can see Eiskarlspitze (left) and Spritzkarspitze (right).
I masked the sky to be able to optimize mountain landscape and sky separately. Finally I added a small radial gradation filter with the sun star in the center of it to reduce overexposure at that part of the picture and make the sunstar appear a bit clearer.
Despite this Red Squirrel's environment being severely reduced by forestry works it has chosen [at less temporarily] not to relocate.
From a 58 MB file I have reduced this down to 2.8MB but it still displays blurry. Perhaps this is temporary and Flickr will "accept" it in clear display.

This is an image of part of the Veil Nebula - a Supernova remnant found in the constellation of Cygnus. While often imaged in narrowband this image is a broadband version.
Present in this area of the complex is the Witch's Broom Nebula, NGC 6960 and Pickering's Triangle.
The filamentous nature of the nebula is due to the interstellar shockwave from the supernova causing glowing filaments of excited interstellar material.
The red colour is due to atomic hydrogen and the teal colour is due to oxygen. These being separated into filaments.
The blazing star is giant 52 Cygni and is not connected to the nebula, its position being a line of sight effect.
The Witch's broom is around 35 light-years across and lies at a distance of 1400 light-years.
Pickering's Triangle is the fainter of the two and has no formal NGC number although NGC 6979 is occasionally used as reference.
Although imaged last October due to personal circumstances I have only just got around to analysing the data.
As always many thanks for looking!

Magnetic goop known as ferrofluid
Ferrofluid: When magnets go nano
For this I used a pipette, ferrofluid , petri dish and lots of paper towels.
Coloured lights.
A ferrofluid is a liquid which becomes highly magnetized in the presence of a magnetic field. The distinctive ‘spikey’ shape of a magnetized ferrofluid is caused by the need to find the most stable shape in order to minimize the total energy of the system, an effect known as the normal-field instability. The fluid is more easily magnetized than the surrounding air, so is drawn out along the magnetic field lines, resulting in the formation of peaks and troughs. However, the extension of the ferrofluid is resisted by gravity and surface tension.
The more complicated explanation is all about nanoparticles. Back in the 1960s, experiments in chemistry showed that ferrofluids could be created and stabilized — a discovery actually made by NASA while searching for ways to control liquid fuel in the weightlessness of space.
Okay, but how does the ferrofluid magically transform into spikes and those crazy hedgehog shapes?
Think of it as a very careful chemical balancing act involving many different forces all hitting a sweet spot. Imagine that you apply a magnetic force to a ferrofluid, say, through a permanent magnet you have lying around
Ref: Tyler Lacoma
Ferrofluids are also the focus of current scientific research and have the potential to be used in many medical applications. In magnetic drug targeting for example, where drugs could be enclosed by ferrofluid and, once injected into the specific body area requiring treatment, a magnetic field could be applied to keep the drugs in this target area. The localization would limit exposure to the rest of the body and enable the dosage level to be decreased, reducing the adverse side effects experienced by the patient
Safety in the use of Ferrofluids and Magnets is recommended.

From ancient times to the present, philosophers have repeatedly emphasized the importance of living a frugal or minimalist life. The ancient Greek philosopher Diogenes said, “True wealth is not in increasing possessions, but in reducing one’s needs.” Mahatma Gandhi pointed to the destructive side of human greed, stating, “The Earth has enough for everyone’s needs, but not enough for everyone’s greed.” From the Buddha to Karl Marx, across the passage of time, many have expressed similar ideas. This minimalist concept in philosophy has greatly influenced the photographer, and its mark is clearly visible in his vision and framing.
The absence of color or the use of minimal composition in framing reflects the photographer’s inclination toward a minimalist approach. The fog, wrapped like a thick winter blanket, creates a serene atmosphere. In this calm and pure dramatic setting, human presence becomes secondary. Before nature, even humanity’s vast achievements become insignificant. That is why the photographer has kept humans and their architectural achievements in the background, framing the scene in a minimalist style. Here, nature is the primary subject—not humans or their constructions.
According to nihilism, or the philosophy of pessimism, human life does not has inherent purpose. Evolutionary theory has shown that humans are an unintended outcome of nature’s evolutionary process. Yet human beings, regarded as the finest of creations, continue to exploit all their knowledge and effort into seeking meaning in life. They establish ever-greater architectural structures upon the heart of nature. In proving their superiority, they seem to challenge nature itself. Viewing nature as an adversary, humanity gradually distances itself further and further from it.
