Our average temperature for the whole month of January in this part of Northeast Ohio has been 21.6° (–5.5°C). Winter's not been here for a month yet, and it can already be called the coldest in about the last 5 years. These two northern cardinals don't seem to mind the frigid conditions. Male in foreground and female in back.
One source says the Nyenchen Tanglha Mountains range is about 1,000 km (620 mi) in length. Its highest point is 7,090 m (23,260 ft) located 100 km (62 mi) to the northwest of Lhasa. The range is parallel to the Himalayas in the Transhimalayas, and north of the Brahmaputra River. [3] Another source says the Nyenchen Tanglha Mountains extend 460 miles (740 km) from Nyêmo County in the west to Ranwu County (the southwestern part of Baxoi County) in the east.
Its highest peak is Mount Nyenchen Tanglha (Nyainqêntanglha Feng) at 7,162 metres (23,497 ft).[4]
The southern side of the Nyenchen Tanglha Mountains is precipitous, and falls by around 2,000 metres (6,600 ft), while the northern side is fairly level and descends about 1,000 metres (3,300 ft). Most of the mountains are below 6,500 metres (21,300 ft).[5] They contain 7080 glaciers covering an area of 10,700 square kilometres (4,100 sq mi).[4]
The Nyenchen Tanglha Mountains have an average latitude of 30°30'N and a longitude between 90°E and 97°E. Together with the Gangdise Shan located further west, it forms the Transhimalaya [a] which runs parallel to the Himalayas north of the Yarlung Tsangpo River.
The Drukla Chu river rises in the Nyenchen Tanglha Mountains, where it is called the Song Chu river, and joins the Gyamda Chu river. The combined rivers run about 100 kilometres (62 mi) southeast to the Yarlung Tsangpo river.
The first time I saw a real HDR frame I was truly taken aback (I remember it was a huge yellow excavator under an amazing late afternoon sky) ... That moment really pushed me into taking up photography as a really serious hobby ... I really couldn't imagine how on earth can a photographer actually represent the true lighting and color conditions of an all around low light scene with such unsurpassed accuracy and precision ... It then became one of my noble pursuits to try to master the technique in the best possible way (all these about eight years ago) ...
Since then I experimented a lot ... Both on photo shooting sites as well as at home ... I still do ... When I find an excellent landscape ahead of me I try to create a masterful synthesis and then I try to enclose this synthesis into my camera's sensor using a variety of camera adjustments ... Even minor adjustments can make a difference from an elegant frame to an excellent one ... Exchanging focusing points on the overall vista, as well as altering Exposure Compensation and aperture values are some of these adjustments ...
Of course three more things one should always bear in mind: The first is to always shoot RAW, the second is to use a steady tripod and last but not least buy an excellent HDR Software from the tens that exist out there that suits one's processing skills and final aesthetic outcome on a frame and master it ...
NIKON D90 DSLR with Nikon Nikkor 18 - 55 lens, Manual Mode, shutter speed 1/80 s, ISO 200, f 10, focal length 18 mm, use of HOYA ND X 2 filter, cloudy weather white balance, center weighted average metering mode, exposure compensation set to -1 EV, HDR processing derived from only one RAW file, no flash, use of tripod ...
A habit? An escape? An addiction?
According to the statistics in the UK and US people are watching TV an average of 3-4 hours per day, every day.
If I only count up to 80 years, that's 10 years without sleeping, 87.600 hours in blue light from birth to death.
Adverts, news, weather, sport, shows, movies, episodes, repeat...
Is this how we are supposed to spend our time on Earth in our evenings till the end?
We all need escapes, no question about that. But it matters where we escape into and for how long for.
I stopped broadcast TV 15 years ago and stopped streaming from devices 5 years ago. I'm off the Blue Wheels now.
What can I report?
I've spent around 2000 evening hours on learning to play the guitar, then 2000 evening hours on creating, thinking, reading, learning and writing thanks to learning photography.
The next thousands of blue light free evenings will contain learning meditation, drawing a portrait, sculpting a bust, clarinet, trumpet, the list will go on as long my mind and body will go on.
I was born into TV culture and only by being away from it I've gained perspective and insight for myself that I wasn't just consuming TV - TV was consuming me and my time.
I feel extremely grateful that I have this pocket of time available to me just now, and for living in an era where most lessons/knowledge is free and available at my fingertips to grow and be more balanced in my life.
My evenings are containing silence, palpable joy and meaning personal to me now. TV is not designed to give me those, it's not in it's nature.
TV is designed only to give me the blues.

This fish grows to an average length of 8 inches, and moves about the reef slowly, rowing with its pectoral, dorsal and pelvic fins, using its caudal fin only when it perceives danger.
The most striking feature of this species its triangular shape in cross section, a feature enforce by a bony carapace.
Its lips are pursed and protuberant, used to direct a blast of water to move sand, revealing small invertebrates such as small worms and crustaceans.
When the fish is stressed its skin releases mucus containing a defensive chemical, ostracitoxin.
More than any other fish on the reef, smooth trunkfish evoke a reaction of "cute!"

What is one thing the average driver can't stand? Well of course one answer could be a slow driver in the fast lane, Highway Patrol posted up in the most annoying spot possible, or maybe even that damn check engine light. However, the answer I was looking for was waiting for a train, and during this trip for the crew of a southbound, they would see three cars try to beat the train. One was a truck just south of Maxwell, which a buddy and I saw, another in Arbuckle, and then another here just outside Williams. However, this driver was particularly stupid.
Although my friend and I didn't see this happen as we were taking photos at the time, another friend who was one of the crew members explained to me what happened. As the train was approaching the crossing, a white SUV went around the gates in an attempt to beat the train, but then suddenly stopped. Although there was nobody in front of this car, whoever was driving then proceeded to backup almost into the gate, and due to the angle of the crossing got within only a few feet at most of being hit, narrowly avoiding an expensive and embarrassing trip to the auto shop. The crew obviously was pissed, and the conductor got out to yell at the driver as they passed by. It was only after the power had passed that my friend and I on the ground noticed the SUV, and we laughed knowing well that driver probably needed a new pair after that.
The average female Praying Mantis lays three egg masses with an average of 50 eggs per mass. The mass is a sticky fluid that dries soon after the eggs are laid and is similar to styrofoam as it insulates her eggs through the cold winter, then hatch in mid spring when temperatures are ideal.
Our daily average temperature has been dropping since July and hit rock-bottom a few days ago. Today the tide turned and we inched up a degree if this were a "normal" year. To celebrate, here's a look back at those balmy summer days. The orange sulphur is sometimes called the alfalfa butterfly because its caterpillars like to eat alfalfa leaves. However, the caterpillars also eat the leaves from a variety of other legume plants. Females have light-colored spots that break up the solid black bands that form a border on their dorsal wing surface, visible in this backlit view. Male orange sulphurs would be all black along that wing border.
The low cloud on the horizon had turned last Wednesday's outing in to a pretty average evening, but an unremarkable sunset can still deliver whern you're at a remarkable location such as this. Incredible rock textures, amazing colours too, and in the end the colour in the sky complemented the rocks nicely. I wish I could have been a foot further back, but then I would have needed flippers! :)
Your comments and faves are greatly appreciated. Many thanks.
Cockatiel
Scientific Name: Nymphicus hollandicus
Description: The Cockatiel is an unusual member of the cockatoo family. It is small in size, and has a slender body and long pointed tail, which is more characteristic of the smaller parrots. Its plumage is mostly grey, paler below, with a white wing patch, orange cheeks and a distinctive pointed crest. The male can be identified by its bright yellow forehead, face and crest. Young Cockatiels resemble the adult female, although the young males usually have a brighter yellow face. The Cockatiel is not found naturally in any other country, but is a popular cage bird, second only to the Budgerigar, Melopsittacus undulates. The Cockatiel does not have the screeching voice of many other parrots and may learn to 'speak'.
Distribution: The Cockatiel is widespread throughout mainland Australia, but is uncommon in Tasmania, with only a few sightings being reported to date.
Habitat: The Cockatiel is seen in pairs or small flocks, in most types of open country, usually near water. It is common throughout its range, especially in the north and the more arid inland areas.
Seasonal movements: Throughout its range, the Cockatiel is strongly nomadic, moving around in response to the availability of food and water.
Feeding: Cockatiels feed on a variety of grass seeds, nuts, berries and grain. They may feed either on the ground or in trees, and always in small to large numbers. Cockatiels roost in trees near water and travel from these areas in large flocks to feeding grounds.
Breeding: Cockatiels may breed at any time, in response to suitable periods of rain, especially in the more arid regions. Both sexes share the incubation of the eggs, which are laid in a hollow, high up in trees. Suitable trees are either in or close to water. Cockatiels enter the nest hollow tail first.
Calls: Although mostly silent, the Cockatiel gives a long and distinctive "queel-queel" in flight. It does not have the screeching voice of many other parrots and may learn to 'speak'.
Minimum Size: 30cm
Maximum Size: 33cm
Average size: 32cm
Average weight: 90g
Breeding season: Normally July to December in south of range
Clutch Size: 2 to 9, usually 5
Incubation: 19 days
Nestling Period: 30 days

The American alligator is a relatively large species of crocodilian. On average, it is the largest species in the family Alligatoridae. Large male American alligators reach an expected maximum size up to 4.6 m (15 ft 1 in) in length. American alligators primarily bask on shore, but also climb into and perch on tree limbs to bask if no shoreline is available.
With a picturesque backdrop of the coast mountain range silhouetted in the sky, a short BNSF manifest trundles over the Mud Bay bridge as it makes its way south to the American border. Mixed freights out of Vancouver, BC have been noticeably shorter in recent months. Lower demand for commodities over the US-CAD border have brought freights down to an average of 20-30 cars per train.
How about some more WATCO? This time in the flat lands of Central Illinois. I came down here last year hoping for one of their new GP59s or WSOR geeps leading. Close, but no cigar. That said, I wasn't going to waste good light. So I gave chase to Tuscola and went looking for other things. All told this was a pretty average day down here last year.

Trivia -
Range - Southern Colombia (the Amazons region) , Northern Ecuador and Bolivia, the eastern part of Peru, and in northern Brazil.
A very elusive, shy mammal - listed as 'Threatened' as per the IUCN list - besides animal and bird predators, they are a prime target for human hunters and poachers, as they can command up to $4000 in the exotic pet black market trade.
Also called the "Finger Monkeys" as they are the smallest monkeys in the world, full grown adult averages 4-6 inches (10-16cm) in body length, weight is around 100 gms. The tail is longer than the body averaging from 6-9 inches (15-23cm), is not prehensile - its mostly used for balance.
Primary diet is tree sap - they puncture the tree bark with their sharp lower teeth to lap up the sap but are not averse to include butterflies, fruits, berries in their diet. Unlike other monkeys they have fingernails shaped as claws which they use to climb trees. They communicate with squeaks and chirps similar to squirrels. Life span in the wild is around 10-12 years, in captivity (zoos, homes) they probably live longer by a year or 2.
The Buff Tailed Bumblebee is one of the most numerous bumblebee species in Europe and has been and maybe still is used in greenhouses for pollination purposes. Nests are usually found underground such as in abandoned rodent dens. Colonies form comb-like nest structures with egg cells each containing several eggs. The queen will lay egg cells on top of one another, the colonies produce between 300/400 bees on average with a large variation in the number of workers, this ensures a division of labour and efficient colony functioning. Workers are entirely female and mainly forage for food, defend the colony and tend to the growing larvae. Unlike queens and workers who develop from fertile eggs the male bees are born from unfertilized eggs and they leave the colony shortly after reaching adulthood to find a mate outside the nest and mating is their sole role in their new colony.

Eastern Great Egret
Scientific Name: Ardea modesta
Description: The Great Egret's overall plumage is white, and, for most of the year, when not breeding, the bill and facial skin are yellow. The feet are dark olive-grey or sooty black, as are the legs. During the breeding season, the bill turns mostly black and the facial skin becomes green. Also at this time, long hair-like feathers (nuptial plumes) hang across the lower back, and the legs become pinkish-yellow at the top. Young Great Egrets are similar to the adults, but have a blackish tip to the bill.
Similar species: The Great Egret can be confused with other white egrets found in Australia. It can be distinguished by the length of its neck, which is greater than the length of its body (and with a noticeable kink two-thirds of the way up), a dark line extending from the base of the bill to behind the eye and the overall larger size.
Distribution: Great Egrets occur throughout most of the world. They are common throughout Australia, with the exception of the most arid areas.
Habitat: Great Egrets prefer shallow water, particularly when flowing, but may be seen on any watered area, including damp grasslands. Great Egrets can be seen alone or in small flocks, often with other egret species, and roost at night in groups.
Feeding: The Great Egret usually feeds alone. It feeds on molluscs, amphibians, aquatic insects, small reptiles, crustaceans and occasionally other small animals, but fish make up the bulk of its diet. The Great Egret usually hunts in water, wading through the shallows, or standing motionless before stabbing at prey. Birds have also been seen taking prey while in flight.
Breeding: The Great Egret breeds in colonies, and often in association with cormorants, ibises and other egrets. Both sexes construct the nest, which is a large platform of sticks, placed in a tree over the water. The previous years' nest may often be re-used. Both sexes also incubate the eggs and care for the young (usually two or three).
Minimum Size: 70cm
Maximum Size: 90cm
Average size: 80cm
Breeding season: October to December in the south; March to May in the north.
Clutch Size: 2 to 6
Incubation: 28 days
Nestling Period: 40 days

The red-tailed hawk (Buteo jamaicensis) is a bird of prey that breeds throughout most of North America, from the interior of Alaska and northern Canada to as far south as Panama and the West Indies. It is one of the most common members within the genus of Buteo in North America or worldwide. The red-tailed hawk is one of three species colloquially known in the United States as the "chickenhawk", though it rarely preys on standard-sized chickens. The bird is sometimes also referred to as the red-tail for short, when the meaning is clear in context. Red-tailed hawks can acclimate to all the biomes within their range, occurring on the edges of non-ideal habitats such as dense forests and sandy deserts. The red-tailed hawk occupies a wide range of habitats and altitudes including deserts, grasslands, coniferous and deciduous forests, agricultural fields and urban areas. Its latitudinal limits fall around the tree line in the Arctic and the species is absent from the high Arctic. It is legally protected in Canada, Mexico, and the United States by the Migratory Bird Treaty Act.
The red-tailed hawk is one of the largest members of the genus Buteo, typically weighing from 690 to 1,600 g (1.5 to 3.5 lb) and measuring 45–65 cm (18–26 in) in length, with a wingspan from 110–141 cm (3 ft 7 in–4 ft 8 in). This species displays sexual dimorphism in size, with females averaging about 25% heavier than males.
The diet of red-tailed hawks is highly variable and reflects their status as opportunistic generalists, but in North America, it is most often a predator of small mammals such as rodents. Prey that is terrestrial and diurnal is preferred so types such as ground squirrels are preferential where they naturally occur. Large numbers of birds and reptiles can occur in the diet in several areas and can even be the primary foods. Meanwhile, amphibians, fish and invertebrates can seem rare in the hawk’s regular diet; however, they are not infrequently taken by immature hawks. Red-tailed hawks may survive on islands absent of native mammals on diets variously including invertebrates such as crabs, or lizards and birds. Like many Buteo, they hunt from a perch most often but can vary their hunting techniques where prey and habitat demand it.

Crawford Hill is located on BNSF Butte Subdivision between Edgemont, SD, and Alliance, NE. East of Crawford the railroad has to climb 821 feet on average grade over 1.55% over the Pine Ridge escarpment. Here eastbound heavy trains get a push from a pair of Crawford Helpers for the 12 mile climb out of Crawford. In 1982 the BN redid alot of the trackage thru here to add double track mainline, reduce the grade, and remove use of the Belmont Tunnel. Now days coal traffic down so train movements aren't as much. I believe only 1 helper crew does the shoving each shift, so the railroad is limited on eastbound capacity thru here as it takes around 90-120 minutes to shove and get back in position.
Peaking out. We're still not finished with winter here though. There is much prediction of when the last frost will appear. The earliest last frost dates range from Feb 5 to 16. The last frost dates range from Apr 23 to 25. The average last frost date for this area is around March 30. Some predict it as March 23. Much confidence and much inaccuracy.
The Kiang is the largest of the wild asses, with an average shoulder height of 13.3 hands (55 inches, 140 cm). It has a large head, with a blunt muzzle and a convex nose. The mane is upright and relatively short. The coat is a rich chestnut colour, darker brown in winter and a sleek reddish brown in late summer, molting its woolly fur. The summer coat is 1.5 centimeters long and the winter coat is double the length. The legs, undersides and ventral part of the nape, end of the muzzle, and the inside of the pinnae are all white. A broad, dark chocolate-coloured dorsal stripe extends from the mane to the end of the tail, which ends in a tuft of blackish brown hairs. Kiang have very slight sexual dimorphism.
The only real predator other than humans is the wolf. Kiangs defend themselves by forming a circle and, with heads down kick out violently. As a result wolves usually attack single animals who have strayed from the group.
Steller's sea eagle (Haliaeetus pelagicus) is a large diurnal bird of prey in the family Accipitridae. A sturdy eagle, it has dark brown plumage with white wings and tail, and yellow beak and talons. On average, it is the heaviest eagle in the world, at about 5 to 9 kg (11 to 20 lb), but may be below the harpy eagle (Harpia harpyja) and Philippine eagle (Pithecophaga jefferyi) in some standard measurements.

Grok Question:
Average annual temperature of Yukon compared to Hawaii?
Answer:
The average annual temperature in Yukon, Canada, is considerably lower than in Hawaii due to their vastly different climatic conditions:
* Yukon: Given its subarctic climate, the average annual temperature varies by region, but for Whitehorse, a significant city in Yukon, the average would be around 0°C (32°F). However, considering the entire Yukon territory, including colder areas, the average might be even lower, possibly around -2°C to -4°C (28°F to 24°F).
* Hawaii: With its tropical climate, the average annual temperature for Hawaii is much higher, typically around 75-78°F (24-26°C) at sea level. This average can slightly vary between islands but remains consistently warm year-round.
So, when comparing the average annual temperature:
* Yukon: Approximately -2°C to 0°C (28°F to 32°F).
* Hawaii: Approximately 24°C to 26°C (75°F to 78°F).
This comparison clearly shows Hawaii's much warmer climate in contrast to Yukon's cold, subarctic conditions.

The Andes are the only barrier to atmospheric circulation
in the Southern hermisphere, its infuence in the
environment is such that has allowed the formation of
the so called Tropical glaciers (called like that because
they are so close to the ecuator).
Snow accumulation: Mountains serve as a barriers to wind
circulation, causing air to move upward which increases athmosphericpreasure. Higher preasure results in water precipitation in the form of rain or snow, depending on altitud and temperature, at the top of the mountain (Brown, 2010)
Glaciers have a very important role: they store water during the wet season and they release that water during the dry season.
“In the last 46 years, Illimani glacier has lost approximately
21.3% of its surface and 22m of thickness, at an
average rate of 47cm a year, reducing the capacity of the
water basin to storage water”.

2021 was another year of above average forest fires. Surprisingly in Vancouver we only experienced one week when smoke drifting in from the interior of the province impacted the local air quality.
3 shots of the filtered sun effect. First, smoky sun reflection on East False Creek water.
Tp date, 2021 is the third most destructive wildfire season on record in the province, after updated statistics showed more than 8,580 square kilometres of land has been burned so far..
British Columbia appears on track for another potentially record-setting wildfire season.
The worst wildfire seasons in B.C.'s history were 2018 (nearly 13,550 square kilometres burned) and 2017 (more than 12,160 square kilometres).
The average European goldfinch is 12–13 cm (4.7–5.1 in) long with a wingspan of 21–25 cm (8.3–9.8 in) and a weight of 14 to 19 g (0.49 to 0.67 oz). The sexes are broadly similar, with a red face, black and white head, warm brown upper parts, white underparts with buff flanks and breast patches, and black and yellow wings.

Fields dedicated to flower bulb production generate gorgeous agricultural landscapes in spring. There is however a sad part in this picture. Bulb production is one of the most contaminant activities in agriculture, with heavy chemical inputs, including systemic pesticides that end up in your garden, affecting the pollinators visiting the flowers. Estimates for the Netherlands reach an astonishing average of 100 kg of active pesticides per ha and 310 and 130 kg of nitrogen and phosphate per ha, respectively (Jansma et al 2002 Acta Hortic 570:191-204). The sad result is that those fields are abiotic, an artificial industrial spring with no bees and butterflies. And that muteness can reach your garden if you plant those bulbs. What to do? Choose organic bulbs (or simply do not buy them).
It was a lukewarm late Spring evening; the water of the canal was flowing silently besides me - a discreet companion for my walk. I could almost feel the thin crescent of the Moon slowly sliding towards the western horizon. One could think that it was a silent evening indeed but, well, the air was overflowing with a most clangorous croaking choir. Oh, the calls of the frogs were so astoundingly diverse... And they jumbled up with the loud chirping of the crickets.
At last the trees thinned out and I was in the open fields and the starry sky was flickering among the grass, all along the ditches. Ops, the stars were still in the sky after all, and the lands were teeming with fireflies. They were gently dancing their love dances, completely oblivious of my presence.
At first I was entranced by their mesmerizing, sparkling motions, which I soon came to envision as plucked notes of mandolines against the orchestra in a Vivaldi concerto (to realize what I am trying to convey you can listen to some minutes of the Concerto for 2 Mandolines, Strings and B.C. in G major RV 532 in the fantastic performance of the Europa Galante ensemble conducted by Fabio Biondi).
At last I started doing my very first attempts at photographing fireflies. This image is the result of my first postprocessing experience of this kind: I hope that you will enjoy it. Hopefully I will post better fireflies shots in the near future.
[Sorry, on smartphones my fireflies look a bit belittled; moreover I am aware that some displays whiten a bit their beautiful yellow light, the magical trick of luciferin/luciferase which has enabled us humans to look far deeper into the workings of cells than before]
It was one of my unfulfilled dreams to photograph fireflies, which, sadly, are becoming a rarity in our countryside; the positive effects of the lockdown for the environment have probably favoured a blooming this year, so I decided to have a try. I followed the advices of a master of fireflies photography, the Bulgarian photographer Hristo Svinarov. However I will eagerly accept hints and positive criticism from everyone who will be so kind to offer it.

I have stacked 10 5-second photos with the Gimp and tried hard to get something decent out of them. As the basic layer I used an image I have obtained by averaging the photos with John Paul ChaCha's Chasys Draw IES Artist: the fireflies themselves were almost obliterated but the landscape were effectively denoised, while the details were improved. After the stacking work in the Gimp I added some small touches with Nik Color Efex Pro 4.
Simply by my natural curiosity I tried the inverted RGB blue channel technique described by Boris Hajdukovic as a possible final contribution to the processing. The results of this interesting trick are utterly unpredictable when we come to low-light captures; I discovered that in this context this technique can effectively isolate the fireflies from the background.
I took quite a few average photos today. In this one I found it (mildly) interesting how the vapour trail parted either side of the chimney.
Then I made it red. (Technical explanation for you there).
The Observatoire de Haute-Provence, which is in the village of Saint-Michel-l'Observatoire in the Alpes-de-Haute-Provence, France, was built in the 1930s and has been added to ever since. The village enjoys an average of 170 cloudless nights per year, which was part of the reason the observatory was built there.
This photo was taken from the boundary fence of the Centre d'Astronomie et Planétarium de Saint-Michel l'Observatoire, which is separate from the observatory.
The meerkat or suricate, is a small carnivoran belonging to the mongoose family (Herpestidae). Meerkats live in all parts of the Kalahari Desert in Botswana, in much of the Namib Desert in Namibia and southwestern Angola, and in South Africa. A group of meerkats is called a "mob", "gang" or "clan". A meerkat clan often contains about 20 meerkats, but some super-families have 50 or more members. In captivity, meerkats have an average life span of 12–14 years, and about half this in the wild.

en.m.wikipedia.org/wiki/Tavar_Zawacki Ontario, Canada- (Correction- this building possibly near Buffalo, NY, USA- thanks for your input and comments) I could find no listing or documentation validating this installation (in Canada) but the work certainly looks like his style. This is my first encounter with this fascinating artist who I may begin to embrace. buffaloah.com/a/main/1665/1665.html
