(Jynx torquilla - Eurasian Wryneck)
Taille : 17 cm (celle d'un moineau)
Envergure : 25 à 27 cm.
Poids : 30 à 45 g
Longévité 10 ans
Le torcol doit son nom à la curieuse façon qu'il a de tordre le cou et tourner la tête dans tous les sens, se nourrit surtout de fourmis. Son bec cache une langue rosâtre longue de plusieurs centimètres, qui reste enroulée quand il ne se nourrit pas. Cette langue est collante. Il l'enfonce dans le sol sableux et récupère ainsi des fourmis, son mets préféré. Il peut aussi déloger des insectes en sondant les crevasses de l'écorce, ou les fissures entre les pierres des murs et des édifices.Il niche depuis l'Europe et l'Afrique du Nord jusqu'au Japon. Ses populations européennes migrent en Afrique tropicale,/

Longevity 10 years
The wryneck owes its name to the curious way it has of twisting its neck and turning its head in all directions, feeds mainly on ants. Its beak hides a pinkish tongue several centimeters long, which remains rolled up when it is not feeding. This tongue is sticky. He pushes it into the sandy soil and thus collects ants, his favorite food. It can also dislodge insects by probing the crevices of the bark, or the cracks between the stones of walls and buildings. It nests from Europe and North Africa to Japan. Its European populations migrate to tropical Africa,

Barn Owl - Tyto Alba
Like most owls, the barn owl is nocturnal, relying on its acute sense of hearing when hunting in complete darkness. It often becomes active shortly before dusk and can sometimes be seen during the day when relocating from one roosting site to another. In Britain, on various Pacific Islands and perhaps elsewhere, it sometimes hunts by day. This practice may depend on whether the owl is mobbed by other birds if it emerges in daylight. However, in Britain, some birds continue to hunt by day even when mobbed by such birds as magpies, rooks and black-headed gulls, such diurnal activity possibly occurring when the previous night has been wet making hunting difficult. By contrast, in southern Europe and the tropics, the birds seem to be almost exclusively nocturnal, with the few birds that hunt by day being severely mobbed.
Barn owls are not particularly territorial but have a home range inside which they forage. For males in Scotland this has a radius of about 1 km (0.6 mi) from the nest site and an average size of about 300 hectares. Female home ranges largely coincide with that of their mates. Outside the breeding season, males and females usually roost separately, each one having about three favoured sites in which to conceal themselves by day, and which are also visited for short periods during the night. Roosting sites include holes in trees, fissures in cliffs, disused buildings, chimneys and haysheds and are often small in comparison to nesting sites. As the breeding season approaches, the birds move back to the vicinity of the chosen nest to roost.
Once a pair-bond has been formed, the male will make short flights at dusk around the nesting and roosting sites and then longer circuits to establish a home range. When he is later joined by the female, there is much chasing, turning and twisting in flight, and frequent screeches, the male's being high-pitched and tremulous and the female's lower and harsher. At later stages of courtship, the male emerges at dusk, climbs high into the sky and then swoops back to the vicinity of the female at speed. He then sets off to forage. The female meanwhile sits in an eminent position and preens, returning to the nest a minute or two before the male arrives with food for her. Such feeding behaviour of the female by the male is common, helps build the pair-bond and increases the female's fitness before egg-laying commences.
Barn owls are cavity nesters. They choose holes in trees, fissures in cliff faces, the large nests of other birds such as the hamerkop (Scopus umbretta) and, particularly in Europe and North America, old buildings such as farm sheds and church towers. Buildings are preferred to trees in wetter climates in the British Isles and provide better protection for fledglings from inclement weather. Trees tend to be in open habitats rather than in the middle of woodland and nest holes tend to be higher in North America than in Europe because of possible predation.
This bird has suffered declines through the 20th century and is thought to have been adversely affected by organochlorine pesticides such as DDT in the 1950s and '60s.
Nocturnal birds like the barn owl are poorly monitored by the Breeding Bird Survey and, subject to this caveat, numbers may have increased between 1995-2008.
Barn owls are a Schedule 1 and 9 species.

Sächsische Schweiz (Elbsandsteingebirge)
de.wikipedia.org/wiki/S%C3%A4chsische_Schweiz
Als Sächsische Schweiz wird der deutsche Teil des Elbsandsteingebirges in Sachsen bezeichnet. Die durch bizarre Felsformen geprägte Landschaft liegt südöstlich von Dresden beiderseits der Elbe im Landkreis Sächsische Schweiz-Osterzgebirge.
Bergformen
In der Regel sind zwei Bergformen zu unterscheiden. Als Steine werden zahlreiche Felsformationen des Elbsandsteingebirges in der Böhmischen und Sächsischen Schweiz bezeichnet. Prominente Beispiele sind der Königstein, der Lilienstein, Gohrisch und Papststein. Die Bezeichnung erstreckt sich nicht auf die hügelartigen Kuppen aus vulkanischem Basalt oder granitischem Material des Grundgebirges wie die Waitzdorfer Höhe oder den Großen Winterberg.
Die kretazischen Sandsteingebilde ragen aus den sogenannten Ebenheiten heraus, dem ehemaligen Niveau der Elbe, und stellen ihrerseits Reste einer früheren Rumpffläche dar. Im Zuge der spättertiären Anhebung des Erzgebirges und des seitlichen Druckes vom Lausitzer Bergland zerbrach die Sandsteinplatte kreuzgitterartig, was bei gleichzeitig zunehmender Fließgeschwindigkeit der Elbe und rückschreitender Erosion in den Seitentälern Angriffsmöglichkeiten und Leitbahnen für die zerstörerische Kraft des Wassers bot. Zunächst verblieben die größeren Tafelberge (Lilienstein), oder bereits stark zerklüftete wie Zirkelstein oder Kaiserkrone, oder aber bereits bewaldete (Kohlbornstein), die sich bei weiterer erosiver Zerstörung in langgezogene Grate (Schrammsteine) bis hin zu einzelnen Felsnadeln (Torwächter) auflösten. Morphologisch härtere Schichtpartien, die der Erosion länger und erfolgreicher Widerstand leisten, bilden meist die oberste Schicht. Der Zusammenbruch erfolgt somit meist von unten her bzw. von den Felsflanken.

Saxon Switzerland - Elbe Sandstone Mountains
en.wikipedia.org/wiki/Saxon_Switzerland
Saxon Switzerland (German: Sächsische Schweiz) is a hilly climbing area and national park around the Elbe valley south-east of Dresden in Saxony, Germany. Together with the Bohemian Switzerland in the Czech Republic it forms the Elbe Sandstone Mountains.
Saxon Switzerland alone has some 1,000 climbing peaks, as well as several hollows. The area is popular with local and international climbers.
The administrative district for the area is Sächsische Schweiz-Osterzgebirge. The fortress of Königstein is a well-known landmark.
Hills
As a rule, two types of hill may be distinguished.
Numerous rock formations in the Elbe Sandstone Mountains, in both Saxon Switzerland and Bohemian Switzerland, are known locally in this region as Steine ("rocks"). Prominent examples are the Königstein, the Lilienstein, the Gohrisch and the Papststein. This description does not, however, include the dome-shaped Kuppen such as the Waitzdorfer Höhe or the Großer Winterberg, whose bedrock is made of volcanic basalt or granitic material.
The Cretaceous sandstone formations soar above the so-called "levels" of their surrounding area, the former level of the River Elbe, and represent the remains of an old peneplain. In the course of the Late Tertiary, uplifting of the Ore Mountains and sideways pressure from the Lusatian Highlands shattered the sandstone plate along lines that intersected like a grid and this, combined with the simultaneously increasing stream velocity of the Elbe and regressive erosion in its side valleys, offered new lines of attack and new routes for the destructive power of water. Initially the larger table hills (Lilienstein), or those already deeply fissured like Zirkelstein, Kaiserkrone or already forested (Kohlbornstein), remained, but these too broke up later as a result of erosive destruction into long ridges (Schrammsteine) or even into individual rock pinnacles (Torwächter). Morphologically harder sections of strata, that resisted karstification longer and more successfully, generally form the uppermost layers. The collapse of rock structures is usually therefore a result of erosion from below or from the flanks.
the fissure in the sunset bokeh ball reminds me of the fissure in humanity. strangely, in a time of global pandemic, compassion is lacking. interdependence is ignored. we humans are complex!
yet this image also reminds me of what’s good in the world: connection, light, beauty, vulnerability, strength, and kindness. it’s in these bursting flowers. it’s in us, too.
Taken in early October, leaves littering the rock face of the lower section of Toms Branch Falls in Deep Creek. This is perhaps one of the easiest waterfalls to access in Western North Carolina, and in parts one of the more scenic. The face beneath the running water over grown with moss, cracks in the rock face from centuries, perhaps even millennia of water freezing in the deep winter, creating fissures, creating intrigue. The added light, and high contrast scene painting a picture of time standing still, you can almost hear the water rolling, smell the fall leaves not yet washed away, feel the spray over your face and hands even as the temperatures begin to drop. This is why we really love fall, and yet yearn for spring.

Quand la fissure de la banquise rejoint le ciel pour faire qu'un.
(C'est le moment de l'année qu'il faut être prudent sur le bord du fleuve. Je savais que la marée était montante donc je n'avais pas d'inquiétude à ce que la banquise cède sous moi.)
An overview of the Meradalir eruption in SW-Iceland, taken just before midnight on the first day, 3 August 2022. In the back are lava fountains on a fissure, about 200 m long, which is a vent for magma streaming up at the rate of about 20 cubic metres per second. In front of the fissure is a lake of lava. The edges of the lava "freeze" and build up solid "walls" that contain the molten rock within, until fresh streams of lava overflow them or breach through. The view over the Meradalir valley in the brief August night is quite surreal and spectacular.
I was going to call this "in the groove", but the more I looked at it and the numerous fissures in this limestone pavement, I thought "points failure" was more apt!
This is actually the "lone tree" at Malham which appears to be sadly dying of "ash dieback" like many other trees up here in the Dales.
I was hoping for a decent sunset, but it didn't really happen. The light at this point about 30 minutes before sunset was pretty good though and brought out some nice detail and textures.

Looking west over a portion of the lava field toward Mt. Bachelor and South Sister in the distance.
Like Pilot Butte in nearby Bend, Lava Butte is one of the hundreds of cinder cones, fissures and vents populating the slopes of the massive Newberry Volcano, and it is a part of one of the most volcanically active geological areas in the country. Standing roughly 500 feet above its surroundings, Lava Butte was created when gas-charged basalt spewed from a fissure, and as the debris cooled in the form of cinders, it gradually piled up.
Thanks for taking a look, and for any comments, faves and suggestions.

This was stark reminder of how hardy these ferns are as they seemingly thrive in the harsh Karst Limestone landscape on the Gait Barrows, near Silverdale in North Lancashire.
I spent a few hours rambling around the incredible Limestone Barrows here and I must have sat for at least 90 minutes waiting for the forecast "sunny spells" to arrive, before finally packing up. It was as grey as an "Elephants Ear" as I waited to take a shot of a lone pine tree emerging from a slab of Carboniferous Limestone. It would have looked great with a bit of sunshine, but hey that can wait for another day.
The bare Karst Limestone landscape here is very different to any of the other areas up here in the North of England. The surface is incredibly resistant to erosion and the fissures are far less frequent and very narrow. I will post a few more shots in due course and I will get back to the location when we get some decent weather.
