Black-tailed Deer (Odocoileus hemionus columbianus)
I came upon these two youngish bucks during rut a few years ago. Without a doe anywhere in sight they did a little friendly sparring for what I can only assume was practice and perhaps venting a little testosterone build up. After a few minutes of wrestling the downhill looser spent a moment or two grooming the victor.

His testosterone fuelled performance was so treating the rival took off without challenging him ! "
Thank you most kindly for stopping by to view my work.
If you find you have a few words to say about what I have done they will be much appreciated.
My best regards to you.... Martin

Male Elk grazing on some of the last grass along the Firehole River in Yellowstone. This was one of three male elk we saw in Yellowstone on our visit.
Bulls begin to grow antlers in early spring, soon after shedding those from the previous year. Summer visitors will find these antlers covered in a soft skin, commonly known as velvet, which provides nourishment to the antlers as they grow. Besides being smaller, females do not have antlers. Bulls begin to “bugle” a high-pitched whistling sound in late August. Some biologists view bugling not as a challenge to rival bulls, but rather as an expression of the pent up stress and emotion that attend the mating season. Elk are seen in all habitats, but tend to be in high country midsummer through fall, and then return to lowland valleys for the winter months.
Elk are the most abundant large mammal found in Yellowstone. European American settlers used the word “elk” to describe the animal, which is the word used in Europe for moose (causing great confusion for European visitors). The Shawnee word “wapiti,” which means “white deer” or “white-rumped deer,” is another name for elk. The North American elk is considered the same species as the red deer of Europe.
Due to their huge antlers, bull elk are one of the most photographed animals in Yellowstone. Bull elk begin growing their first set of antlers when they are about one year old. Antler growth is triggered in spring by a combination of two factors: a depression of testosterone levels and lengthening daylight. The first result of this change is the casting or shedding of the previous year’s “rack.” Most bulls drop their antlers in March and April. New growth begins soon after.

While visiting Estes Park Colorado back in October, I found myself in a very uncomfortable situation. After seeing some 10-12 elk just off the road in a field, I decided to pull off some 100 or so yards ahead and walk back to get a few shots. While standing and shooting, now some 30 yards from my subjects, I noted dozens and dozens more coming over the hill between my car and I. Getting back to the car wasn’t an option, but where I stood for the moment felt safe.
Within seconds I noticed dozens and dozens more cresting the hill…directly in front of me. I distinctly remember saying aloud…” Well Crap!”
The large herds of elk that descend into Estes Park every fall is called “The Gathering” for a reason. The rut has all but ended and now they come together for safety in their numbers to survive the winter together. I had no idea just how many there would be as I now stood like a rock in a stream with possibly 80-100 elk all around me. The racks on the bulls were intimidating, but it was the females, known as cows with their young calves that provided me the most concern. As they walked past, I lowered my camera in an attempt to view 360 degrees around my position and to not provoke these normally non aggressive creatures.
It was only when this big boy started to pass did, I really start to get nervous. I could see him making his way through the others in a direct line to my location. I slowly back-stepped to the other side of the two-lane road…it was truly my only option!
Prior to our arrival in Colorado, I had several discussions with friends about my dream bull elk shot…the classic full body shot while bugling and with its breath visible in the cold, crisp air. I wasn’t granted the shot I desired, but when this monster (somewhere around 900 lbs.) looked into my eyes and started bugling right at me…I could sense his bad mood and almost smell that breath that I had hoped to capture!
As previously mentioned, on several occasions I have been blessed to see bull elk, but only from extreme long distances. I was equipped with lenses that could cleanly reach out 1200mm…this shot was taken at 214mm. I had prayed to get closer for a good shot on this trip, the purpose to photograph elk…but this encounter was a crazy blessing!
No elk nor photographers were harmed in the making of this picture!
Bull Elk are on testosterone overload during the rut and it doesn't take much to provoke them. Like just driving by.
The fallen leaves give away the time of year… Autumn is breeding season for the Fallow Deer at Charlecote Park in Warwickshire. The male deer (bucks) compete for the attention of the females (does) through rutting. The deer rut is triggered by a drop in temperature and the shortening of day length. This sets off a release of testosterone in the males.
Yea, the Hooded Mergansers have arrived! And what a courtship show the boys put on this particular morning. You can see a couple here throwing their hoods back and forth. Females not too sure about it -- well, they probably don't want to get run over by all the flying testosterone (or Hoodie equivalent).

The red deer rut begins in September and lasts until around early November. During this time, competing males, pumped full of testosterone, will engage in a series of behaviours aimed at showing off to the hinds (female red deer) and establishing dominance over the other stags.
These big bull elephants are often seen alone - until they are in musth. Musth makes them grumpy and aggressive and is caused by a massive increase in testosterone (up to 60x the normal level!). It's mating time when this occurs and then they lookin' for female company and have to fend off other bull elephants for their prize!
PLEASE, NO invitations, graphics or self promotions, THEY WILL BE DELETED. My photos are FREE to use, just give me credit and it would be nice if you let me know, thanks. This is in a highly populated area, apartments, houses, schools, stores etc…
These deer were at the Canada Games Centre when I was going to the gym Friday morning, I go 5 days a week.

Health Update: 6 months ago my Testosterone level was .86 (normal is 8-32) after prostate cancer was treated, the nurse told me at a follow-up to do some weight training. In 3 months my testosterone went up to 5, 3 months after that (last week) I am ups to 11 and my PSA is undetectable which is great.

[FR] Les signaux visuels basé sur la couleur est un aspect important de la communication chez plusieurs espèces d’oiseaux. Chez les tétraonidés un de ces signaux est le peigne superciliaire, cet ornement formé de peau qui se gonfle chez le mâle durant la pariade en raison de l’augmentation du flux sanguin vers les tissus. Des recherches ont démontré qu’il y aurait une corrélation positive entre la grandeur mesuré des peignes, du niveau de testostérone et du succès copulatoire. Par contre il n’y aurait pas de de corrélation entre la dimensions observé des peignes et les comportement de combats entre mâles.

[EN] Color-based visual cues is an important aspect of communication in several bird species. One of these signals in grouse species is the supra orbital comb, this ornament formed of skin that male raise during courtship due to increased blood flow to the tissues. Research has shown that there is a positive correlation between the measured size of the combs the level of testosterone and copulatory success. On the other hand there is no correlation between the observed dimensions of the combs and the fighting behavior between males. These are retracting their combs during confrontation probably to protect this attribute.

'Marsupial mouse', spotted this rare little fellow, couldn't get a step closer, HFF
Antechinus mating season is his one chance to pass his genes on to the next generation, and he will die trying. He exhausts himself so thoroughly that his body starts to fall apart. His blood courses with testosterone and stress hormones. His fur falls off. He bleeds internally. His immune system fails to fight off incoming infections, and he becomes riddled with gangrene.
He’s a complete mess, but he’s still after sex. “By the end of the mating season, physically disintegrating males may run around frantically searching for last mating opportunities,” says Diana Fisher from the University of Queensland. “By that time, females are, not surprisingly, avoiding them.”
Soon, it’s all over. A few weeks shy of his first birthday, he is dead, along with every other male antechinus in the area.

The Testosterone filled the air!!
I took my Grandson Jack with me hoping the rutting would still be happening. Never seen it before........three pairs rutting at the same time. Jack was totally amazed. Knole Park. 22-10-20
Car shows can be a joy to shoot at, but sometimes it's more than just the cars. The people who attend can be just as interesting as the subject cars...sometimes, more so! As seen through the eyes of a 20 year old in an 83 year old body! Beautiful cars, and beautiful women...what a world!
The glow around the Prince's antlers is the sun reflecting on his velvet, a soft hairy skin. From March to August, velvet carries blood to nourish the antlers while they grow. Antler bone is the fastest growing bone known, spurred on by testosterone. By mid September the rutting season is well over, testosterone levels drop, the flow of blood to the velvet slows, the buck rubs it off, and the antlers shed. This helps the buck to maintain a good body temperature during the winter - no freezing air hitting the exposed bone.
Seeing white-tailed deer is a daily occurrence in rural Virginia, but this is the first time one posed for me.
Sans doute des relents de testostérone . Ce Bruant chanteur était bien en voix aujourd'hui !! : )
No doubt hints of testosterone. This Singing Sparrow was good in voice today !! :)
A pattern in our activities seemed to be emerging. On one day, we’d lounge about by the pool, reading, swimming and dozing until lunchtime, before heading down to the beach, where we’d read, swim and doze until sunset. On the next we’d lounge about by the pool, reading, swimming and dozing until an hour before lunchtime, before heading off in the car to examine the fare on offer at some local hostelry and then spending the rest of the daylight hours exploring the volcanoes, or one of Cesar Manrique’s island masterpieces, or driving around in a desultory manner until we found ourselves somewhere interesting. It was the sort of pattern we like – not too challenging as we made the most of that long break under warm blue skies while at home our loved ones shuddered and shivered as the long dry spell gave way to days of deluge and plunging temperatures. Lanzarote was treating us well and we were content to soak it all up without over exerting ourselves.
A week into our low octane adventures and by Saturday afternoon we hadn’t even managed to drag our lazy carcasses as far as the local beach. If we were following the pattern then we ought to have been somewhere other than the poolside by 4pm, but then again perhaps we hadn’t realised there was a pattern yet. Still, there was one local spot I’d wanted to investigate that was just a little too far away to walk to, and now seemed as good a time as any to go and gaze across the handful of miles that separated us from the neighbouring island of Fuerteventura, whose bulk sat appealingly on the horizon whenever we glimpsed the sea here at Playa Blanca. Throughout each day, competing ferry services chased back and forth across the divide, transporting passengers to Playa Blanca’s sister resort at Corralejo, whose lights would glow across the dark water each evening. Another mini world, so close at hand; another untamed landscape waiting to be explored. Each time we left our resort in the car and drove past that patch of undeveloped ground towards the roundabout that leads away from the town, the uplifting view of Fuerteventura, with the small island of Lobos to one side filled the windscreen and drove the imagination. I’ve seen worse views across patches of wasteland you know. And if we could see it so well from here, how would it look if we plonked ourselves down at the most south westerly viewpoint available to us down by the lighthouse of Punta Pechiguera? It was only ten minutes away in the car and on an afternoon where sloth had threatened to steal the day entirely, today seemed like a good time to make that short pilgrimage.
Disappointingly, I’d already realised that the sun itself was setting well away from the jumble of dark slopes and features in the hinterland behind that distant shoreline. What I didn’t really have much idea about was whether we were going somewhere to sit and enjoy watching the sun go down, or if I’d find some photography to entertain myself with. While I hoped for the latter, I wasn’t certain that the silhouette of another land mass ten kilometres across the breach would in itself be enough. But what I found brought promise, initially in the form of rocks and pools where bringing the tripod low would reduce the featureless middle ground in my compositions. While some of the better results included that setting sun, what I really wanted was the Fuerteventura story, the one that spoke of the bond between these two stunning islands in the latitude where it’s always summertime. And a little while later I found a foreground that worked and at the same time removed the empty space between the subject and the unconditionally beautiful background. Well, a series of moving temporary foregrounds in fact. It would just be a matter of timing.
I’m not sure whether it’s a coincidence, but this, my third post from the November trip to Lanzarote is also the third that was taken with the long lens. In fact, looking back to that holiday, the 100-400 seemed so enjoy at least as much time in use as the “go to” 24-70 lens. I’m starting to wonder how on earth I ever managed without it, and both here and in Iceland a couple of months earlier the investment repaid me with results even better than I’d dared to hope for. Easy to think of these lenses as being designed exclusively for wildlife and sport you know. It even does a good job as a macro lens although that’s not a discipline I very often apply myself to. But as a landscape tool, the possibilities are ones I was still discovering here, as lazy rolling waves idled across the scene in front of me on a petrol blue sea and the colours intensified in their descent into darkness. And just to finish things off, a brilliant white yacht added a splash of brightness against the dark surrounding tones. Half a second was just enough to catch the motion of each wave without turning the yacht into too much of a blur, and behind them the mountains of Fuerteventura sat contentedly beneath a soft peachy glow, reminding me that it had been almost twelve years since I’d last roamed across them. Our sort of place Fuerteventura. If Lanzarote is laid back, then Fuerteventura is almost comatose. The perfect hideaway for lounging about by pools, reading, swimming and dozing in equally generous measures. For a couple of weeks now I’ve been hovering over the button on the app supplied by my friendly travel agent, and the prospect of another Fuerteventura story is pulling hard at the emotional chains in the darkest damp depths of early January. I’m sure Ali wouldn’t mind going – she regards our Cornish winters with the same level of enthusiasm she used to reserve for that first day of a new academic year in front of a room full of recalcitrant testosterone fuelled sixteen year-olds during her teaching days. She still has sleepless nights. There, I think I’ve convinced myself. Didn’t take long, did it? Push the button time I think!
It is hard to get out away from the family to get shoots sometimes. In this instance we were on a camping trip in the Tetons. I kept telling myself I was going to get a sunrise over the lake but the cold weather always stopped me. This was the last night there, it was now or never. I brought a chair, set up the tripod and waited. I was a bit surprised how many people were out around the lake at this hour. One burly dude in flannel (can you trust a dude alone at a lake in flannel?) sundered up to my spot, just about 10 feet from and sat. And sat. He just stood there looking the same direction I was looking. I could almost feel him looking at my gear out of the corner of my eye. Finally he mumbles, almost as if he were talking to the mountain "6d?" Ok, now I am even more nervous, he knows my gear. He was still not looking at me at all, could he feel the presence of the Canon? "Yes" I replied. Silence. I am ready for anything at this point, testosterone in overdrive. What felt like an eternity passed (about 15 seconds in my overly dramatic mind). Then he reaches into his coat...this is it, he is getting a knife, or a gun..I get ready to rush him, almost leaping across the rocks..then he turns, smiles, and pulls out a Canon 6d also. "Me too" he says. We proceed to talk shop while I am still shaking form the adrenaline rush. This image is for you creepy flannel man.
I already posted one image from this shoot in blue, pre-sunrise. Truth is I liked it better, but I thought I should revisit the set of brackets I shot that morning.
I am always drawn to images that are dark. Usually very dark. They just seem to pull me into the image. The thing is, I keep trying to shot dark images, and process dark images. I just can't seem to get them the way I want, dark. I almost forced myself to keep this dark while I processed it. Looking back, I wish I had gone into the lake to shoot this, it would have been more dramatic.

In October Fallow Bucks have transformed from beautiful spotted and ornate animals of summer into aggressive, vocal and muscular fighting
beasts. They look and behave like a completely different animal. Their antlers are fully grown and hardened and with testosterone raging through their bodies and weight and muscle shifted to their neck and shoulders they are ready to fight !
Thank you for having a look at my photos. Comments or faves are very welcome and much appreciated.
The rut may be full of testosterone fuelled aggression, but several months later there is a beautiful outcome.

I haven't spent much time with Snowy lately as he is down in the back paddock with all his ladies.
I swear he has a new girlfriend everyday.
The cows must be in season or some of them because Snowy will single one out and become completely transfixed on her. He doesn't even like her to mingle with the other cows and he will bunt their calf away if he wants to get down to business.
You can literally feel the testosterone just by looking at him.
Bucks bulk up in preparation for the rut. Most experts believe the added muscle is due to a large boost in testosterone before and during the rut. This guy's neck looks like he has been powerlifting.
At our ringing site today. These Mute Swans were all getting a bit testosterone-driven but we still had some Whoopers around too - what a magical sound in the morning stillness
Another of Richmond's magnificent red stags, busily scenting & adorning his antlers with greenery.
Their transformation at this time of year, from shy & retiring creatures, to bellowing, testosterone-fuelled express trains is incredible.

It's after the rut, but these two mule deer bucks are burning off some excess testosterone. They fought hard enough that one or the other got two or three "stingers", which had one jumping away to rub off the sting.

Sparring one day and buddies the next. Always interesting to see these guys hanging out in such large herds following the rut. This was a group of 22 with another 6 just a few miles away. How many do you see in this frame?
Have a great Monday!!!
This image was inspired by a presentation by Elizabeth Jane Lazenby at my camera club a few days ago. Jane makes use of multi-layered textures to create wonderful versions of her original photos. This is a first attempt to follow her example - I have a long way to go with this style of work, but it is fun and you only find out what works and what doesn't by trying and inviting critique! Check out Jane's work at www.ejlazenbyphotography.co.uk and www.animalfineart.co.uk
spring and summer seasons allow for these whitetail bucks (in velvet stage) to group up while testosterone levels are low which probably allows them to somewhat protect each other from predators and develop of a hierarchy without being to aggressive....velvet stage last several months into fall when they begin to shed, testosterone increases and the battles begin ~
The story may be more interesting than the picture. As a 17 year old I found myself on a Wurlitzer at a fairground in Edinburgh with one other passenger - a lovely girl. I'm not good with things that whirl around. After the first ride she asked if I'd like to go again.The testosterone in me forbade me to get off. Many rides later and feeling very queasy I did get off - and didn't get the girl. The music playing was Ticket to Ride
During the rut, a bull moose's velvet will begin to die when the testosterone levels in his body increase. The velvet becomes itchy so the moose will use trees to scratch the velvet away from his antlers. During the spring and summer, the velvet carries blood to the antlers enabling them to grow.
The bull photographed here was an extremely large example. He scratched his antlers for about a minute before wandering away.
The large pointed tines in the front of the bull's rack are referred to as Brow Tines. In Alaska, the bull moose are much larger than in the lower 48 and southern Canada. Unfortunately, the larger the bull's rack the more sought after they are by hunters.
This bull moose is safe from hunters as long as it stays within Denali National Park's boundaries.

I think Timmy has too much testosterone. That's the same with men: if they have too much of it, they get receding hairlines and later baldness ;-)
Timmy loves to lie on my hand like this. Some time ago, he also lay there like that and warmed my hand. I fell asleep and when I slowly woke up again about an hour later, my hand was still warm. I opened my eyes and - oops - he had turned 180 degrees and now his bottom was lying on my hand. It was even warmer than his head :-))))
i like to think there isn't chewing tobacco in them there cheeks but rather a tank of testosterone... big crop and certainly not the best image quality but i always liked this image and thought it was time to post it!
Red is the color at the long wavelength end of the visible spectrum of light, next to orange and opposite violet. It is a primary color in the RGB color model and the CMYK color model, and is the complementary color of cyan. Reds range from the brilliant yellow-tinged scarlet and vermillion to bluish-red crimson, and vary in shade from the pale red pink to the dark red burgundy.
Red pigment made from ochre was one of the first colors used in prehistoric art. The Ancient Egyptians and Mayans colored their faces red in ceremonies; Roman generals had their bodies colored red to celebrate victories. It was also an important color in China, where it was used to color early pottery and later the gates and walls of palaces. In the Renaissance, the brilliant red costumes for the nobility and wealthy were dyed with kermes and cochineal. The 19th century brought the introduction of the first synthetic red dyes, which replaced the traditional dyes. Red became a symbolic color of Communism; Soviet Russia adopted a red flag following the Bolshevik Revolution in 1917, later followed by China, Vietnam, and other communist countries.
Since red is the color of blood, it has historically been associated with sacrifice, danger, and courage. Modern surveys in Europe and the United States show red is also the color most commonly associated with heat, activity, passion, sexuality, anger, love, and joy. In China, India and many other Asian countries it is the color of symbolizing happiness and good fortune.
Varieties of the color red may differ in hue, chroma or lightness, or in two or three of these qualities. Variations in value are also called tints and shades, a tint being a red or other hue mixed with white, a shade being mixed with black.
The human eye sees red when it looks at light with a wavelength between approximately 625 and 740 nanometers. It is a primary color in the RGB color model and the light just past this range is called infrared, or below red, and cannot be seen by human eyes, although it can be sensed as heat.
Primates can distinguish the full range of the colors of the spectrum visible to humans, but many kinds of mammals, such as dogs and cattle, have dichromacy, which means they can see blues and yellows, but cannot distinguish red and green (both are seen as gray). Bulls, for instance, cannot see the red color of the cape of a bullfighter, but they are agitated by its movement.
One theory for why primates developed sensitivity to red is that it allowed ripe fruit to be distinguished from unripe fruit and inedible vegetation. This may have driven further adaptations by species taking advantage of this new ability, such as the emergence of red faces.
Red light is used to help adapt night vision in low-light or night time, as the rod cells in the human eye are not sensitive to red.
Red illumination is used as a safelight while working in a darkroom as it does not expose most photographic paper and some films. Today modern darkrooms usually use an amber safelight.
At sunrise and sunset, when the path of the sunlight through the atmosphere to the eye is longest, the blue and green components are removed almost completely, leaving the longer wavelength orange and red light. The remaining reddened sunlight can also be scattered by cloud droplets and other relatively large particles, which give the sky above the horizon its red glow.
Red is associated with dominance in a number of animal species. For example, in mandrills, red coloration of the face is greatest in alpha males, increasingly less prominent in lower ranking subordinates, and directly correlated with levels of testosterone. Red can also affect the perception of dominance by others, leading to significant differences in mortality, reproductive success and parental investment between individuals displaying red and those not.

Testosterone! Since the rut is in fall and this was spring, I am wondering if this was two young males. The duel went on for a few minutes without what I would consider an obvious winner.
Note that the spots in the dark tree at left are the raindrops falling as this duel occurred.
