Deer are fascinating to watch and I'm so pleased to have captured this wee behaviour from this impressive Red Deer stag. He was so permanently furious and stompy but mesmerising to watch and capture with my camera. It isnt just deer who do this (Big cats and horses do this too) but it is a known behaviour for scenting females and whilst the stag looks like he is sneering, he stretches his neck, lifts his nose and curls his top lip, maximising exposure to air containing pheromones to his vomeronasal organ, (located in the roof of his mouth). This helps him detect Doe's in Oestrus.
Nature is truly incredible.
Human pollution has affected the behavior of the American white ibis via an increase in the concentrations of methylmercury, which is released into the environment from untreated waste. Exposure to methylmercury alters the hormone levels of American white ibis, affecting their mating and nesting behavior and leading to lower reproduction rates.

Hello my amazing Flickr friends !
Today is a pink or purple day at Color my World Daily and the theme at Smile on Saturday is numbers.
As you can see, Mr. Egg is obsessed with numbers… Since he gained a little bit of weight, he can’t stop measuring himself… He takes note of all the numbers each day. Unfortunately for Mr. Egg, even with all the efforts he makes in order to lose some weight, the numbers are still the same (or almost)… Maybe Mr.Egg’s metabolism has slowed down…or maybe it is hormonal … or maybe it is both… or maybe Mr. Egg eats too much Nutella on his cheat days… We will never know. However, Mr. Egg is very motivated to bring those numbers down before going back to work in few weeks…
Mucho, mucho amor for you all !! Have a beautiful day !
Thank you so much for all your lovely comments / favs/ general support / happy thoughts!! Stay safe and well!!

These two bucks are actually brothers. I saw them earlier this year with velvet on their antlers. Last week they were licking each other's faces, now they are full of hormones and banging heads. The rut has started!

Fasciated Black-eyed Susan Inflorescence in the TWU Butterfly Garden, Denton, Texas
Fasciation (pronounced /ˌfæʃiˈeɪʃən/, from the Latin root meaning "band" or "stripe"), also known as cresting, is a relatively rare condition of abnormal growth in vascular plants in which the apical meristem (growing tip), which normally is concentrated around a single point and produces approximately cylindrical tissue, instead becomes elongated perpendicularly to the direction of growth, thus producing flattened, ribbon-like, crested (or "cristate"), or elaborately contorted tissue. Fasciation may also cause plant parts to increase in weight and volume in some instances. The phenomenon may occur in the stem, root, fruit, or flower head.
Some plants are grown and prized aesthetically for their development of fasciation. Any occurrence of fasciation has several possible causes, including hormonal, genetic, bacterial, fungal, viral and environmental causes. (Wikipedia)
Roundings and hormones for happiness...
Today I show you a different rounding compared to yesterday, a semicircular vault with frescoes.
They are part of a biliotheque and under it students study.
Is the end of our ever-expanding space round? Circles play in any case on our earth and in our life an important role and because the human being is a physilogical premature birth, no other creature comes so clumsily on the world, must be led at least 20 years and the baby already begins in the womb with the learning, the evolution has come up with a reward system for our learning. Learning successes generate happiness hormones in us ... Learning is the most beautiful thing in the world ...
ein paar Gedanken .. heute zeige ich euch, im Vergleich zu gestern, eine ander Rundung, ein halbrundes Gewölbe mit Fresken. Sie sind Teil einer Biliothekt und unter ihr lernen Studenten.
Ist das Ende unseres sich ständig weiter ausbreitenden Weltraums rund?
Kreise spielen jedenfalls in unserem Universum und in unserem Leben eine wichtige Rolle.
Und da der Mensch ein physilogische Frühgeburt ist, kein anders Lebewesen so unbeholfen auf die Welt kommt, mindestens 20 Jahre geführt werden muss und das Baby schon im Mutterleib mit dem lernen beginnt, hat sich die Evolution ein Belohnungssystem für unser Lernen einfallen lassen.
Lernerfolge erzeugen Glückshormone in uns ... Lernen ist die schönste Sache der Welt ...

Welcome to the Looney Bin! One male in hot pursuit of another. In all my years of Common Loon watching I have never witnessed this behaviour. Usually when loons have a turf war they do it under water and come up for a powerful wing smack. They just flapped above the water right past me and continued on down the whole length of the lake while the female watched from the sidelines. I'm not even sure why the loon being chased didn't fly away. I admired their stamina from my kayak, It had to be exhausting. Even though the wind wouldn't die down It was so good to see my loon pair again and take time from my many jobs.

Musth is a completely natural phenomenon seen in mature bull elephants.
Generally characterised by the secretion of a hormone rich substance called temporin from the temporal gland (on either side of the elephant’s head) and a steady trickle of urine down the back legs of the elephant, musth involves a rise in the reproductive hormones in the elephant’s body. This causes the animal to feel more restless, energetic, aggressive or unpredictable – and generally irritable and oversensitive to sounds and movements. Musth is seen in healthy adult bull elephants.

- Oui, le soir, car, proches de la maturité, nos têtes restent fixes, orientées vers l'est...
Jeune, le plan du tournesol "suit" le soleil. Selon Ouest France, la lumière du soleil "a une incidence sur l’auxine, une hormone qui permet l’allongement des cellules de la plante. L’auxine se situe en haut de la tige, mais craint la lumière. Plus la quantité de lumière captée par la plante est importante, plus l’auxine va devoir se déplacer vers les parties ombragées. En clair, au plus près de la base de la plante. Les parties ombragées vont donc grandir plus vite que les parties ensoleillées. Ce faisant, la tige, dissymétrique, penchera en direction de la source de lumière. Voilà pourquoi nous avons l’impression que le tournesol suit le soleil."
Mais "une fois le tournesol arrivé à maturité, [...] (l)a plante se tournera vers l’est et n’en bougera plus. Bref, elle ne suivra donc plus le cycle du soleil.
Pourquoi vers l’est ? Car cette orientation lui permettra de capter le soleil dès les premières heures du jour. Selon une étude de la revue Science, le parfum alors dégagé attirerait en effet cinq fois plus d’insectes pollinisateurs."
Do you turn your backs on the sun?...
- Yes, in the evening, because, close to maturity, our heads remain fixed oriented towards the east...
When young, the sunflower plant "follows" the sun. According to newspaper "Ouest France", sunlight "has an impact on auxin, a hormone that allows the plant's cells to elongate. Auxin is located at the top of the stem, but it is sensitive to light. The more light the plant captures, the more auxin will have to move to the shaded areas. In short, as close as possible to the base of the plant. The shaded parts will therefore grow faster than the sunny parts. In doing so, the stem, asymmetrical, will lean towards the light source. This is why we have the impression that the sunflower follows the sun."
But "once the sunflower reaches maturity, [...] (the) plant will turn east and stay there. In short, it will no longer follow the sun's cycle.
Why east? Because this orientation will allow it to capture the sun from the first hours of the day. According to a study in the journal "Science", the fragrance it releases attracts five times more pollinating insects."

The Superb Fairywren are quite a common little bird in south-eastern Australia, probably the most common bird in Woodlands Historic Park, to the point that I am always trying to stop myself saying things like “it’s just a Fairywren”. They really are amazing little birds. The males look completely different in breeding season when they pimp themselves up in the most beautiful blue and black plumage (see image 1 in the first comment) compared to non-breeding or eclipse plumage (see image 2 in the first comment). They are also incredibly cute when they are in-between the two (see image 3 in the first comment).
The female does not “colour-up” although her tail can sometimes show a blue wash. She is a little more brown than the male, and the easiest “identifier” for me is a brown/orange beak and brown/orange lores around her eyes (see image 4 in the first comment).
When I photographed this little wren yesterday I was not sure whether it was a female or a male. The beak and lores were brown, but not as orange as usual, and the tail was quite a bit more blue than a female usually is. So, I posted the photo on one of the bird identification pages I use, and was pleased to get the following response from Nikolas Haass, one of the experts I most trust.
“one of the difficult ones: either (1) immature (not juvenile) male, or (2) very old adult female (with a shift in sex hormones towards androgens)”
So even the expert wasn’t sure - made me feel better about not knowing !
Superb Fairywrens are socially monogamous but are also sexually promiscuous, meaning that although they form pairs between one male and one female, each partner will mate with other individuals and even assist in raising the young from such pairings.
Pineapple gives you happy hormones!! I'm having two!!

Rheydt Castle is famous for its Renaissance Architecture , its park and its peacocks. This cock was the first one who exercised in a one-cock-show to be prepared for the upcomeing courtship season to persuade a hen.
On the shores of the Atlantic near the Stormsriver mouth at the Tsitsikama Nature Reserve I spotter this little fellow.
The rock hyrax (Procavia capensis), also called rock badger and Cape hyrax, is commonly referred to in South African English as the dassie. It is one of the four living species of the order Hyracoidea, and the only living species in the genus Procavia. Like all hyraxes, it is a medium-sized (~4 kg) terrestrial mammal, with short ears and tail.
The closest living relatives to hyraxes are the modern-day elephants and sirenians. The rock hyrax is found across Africa and the Middle East in habitats with rock crevices into which it escapes from predators. Hyraxes typically live in groups of 10–80 animals, and forage as a group. They have been reported to use sentries: one or more animals take up position on a vantage point and issue alarm calls on the approach of predators.
The rock hyrax has incomplete thermoregulation and is most active in the morning and evening, although its activity pattern varies substantially with season and climate. Adults make use of at least 21 different vocal signals. The most familiar signal is a high trill, given in response to perceived danger. Rock hyrax calls can provide important biological information such as size, age, social status, body weight, condition, and hormonal state of the caller, as determined by measuring their call length, patterns, complexity, and frequency.
While standing out along the edge of a cliff with a bunch of other puffins, this individual stood out visually for obvious reasons, and attracted a bunch of attention.
Some of us speculated that it was a young puffin that hadn't completed the change over to full breeding plumage and colour. But that might have been only be part of the story.
In talking to a longtime puffin photographer and documenter at a local coffee shop the next day, I was given an alternate explanation. Judging by beak wear marks, he believed this may be the same individual that was seen a few times over a few years, and the plumage and beak colour has been the same each year.
He had previously contacted a Scottish puffin expert, who wrote a book on the puffin, who believed it was a very mature female that was lacking some of the hormones that allowed it to develop the characteristic bright breeding colours on the legs and beak, the white facial plumage, full gape rosette (the orange at the base of the beak), and decorative orange and grey skin around the eye.
So, if you see a puffin out on the ocean in the winter, it would look a lot like this individual.
If you've just experienced a hormone surge then this magnificent suit from Avec Toi is for you. The Piper glasses from DS set it off in an appropriately severe fashion as does the Paradox hair from Stealthic.
Applications will be taken for Cara to take this off to show off her new LaraX body. Valuable consideration assumed. Line up in an orderly fashion please!
Milu had her blood results back on Tuesday and although her thyroid hormone levels are not where they should be, they are 'close enough' to quote the vet. So we are maintaining the same levels of Thyronorm and she will go back for her next blood test in three months. There have been times where we have thought "this is it" when she has become lethargic and won't eat but recently she has definitely perked up. She still only weighs 2.9 kilos but apart from screaming like a banshee when I give her medicine (through syringe in the mouth) she appears happy enough. Oh and to all those Youtubers who say just gently wrap your cat in a towel like this - HA! First you have to catch her and then you have to ensure that you have swaddled her to within an inch of her life so she cannot move those dagger claws one inch

From just over a year ago, a Mule Deer buck watches me from tall grass near the river. I was on foot for this one. It's a little more difficult than shooting from the rolling red Toyota blind, because as soon as they identify me as human, they put distance between us as fast as possible. This buck allowed me one shot, then it was gone.
Occasionally, though, I am able to work for an extended time - on foot - with deer and other local species, and these are by far the most rewarding encounters.
I still can't believe how thick his neck is. This was near the start of the annual rut, and the combination of hormones plus workouts - thrashing bushes, grass, and the ground with his antlers - have enlarged and strengthened his neck.
More Mule Deer to follow over the next few days...

I spotted a couple male Sooty Grouse trying to out preform each other. They did not seem to have their hearts in it. Perhaps it is late in the breeding season and their hormone levels have dropped.
The young stags are suddenly a lot more brazen, happy to be seen out, munching in gardens and ground around houses. Perhaps they are getting hormonal in the run up to the rutting season.

This picture shows the imprint of a human placenta over white paper. The red tree is the mother’s blood supply and at the bottom of the picture is the long umbilical cord. The placenta (also known as afterbirth) is an organ that connects the developing fetus to the uterine wall to allow nutrient uptake, provide thermo-regulation to the fetus, waste elimination, and gas exchange via the mother's blood supply, fight against internal infection and produce hormones to support pregnancy.
Les humains sont des animaux territoriaux avec des comportements hormonaux inconscients auquel s'ajoute un égo parfois démesuré... parler du concept de propriété avec eux est donc une perte de temps !
Humans are territorial animals with unconscious hormonal behaviours and a sometimes excessive ego... talking about the concept of property with them is therefore a waste of time!

Each year, at the conclusion of the mating season, bull moose shed their antlers. The process is driven by reduced hormone levels. The older bulls lose theirs first, while younger bulls hold on to theirs a bit longer. This happens sometime between mid-December and mid-January.
This bull moose had just shed his antlers. I shot this on December 7th, so it was a little early. He's likely a much older bull. He was the first bull I saw to shed his antlers. His pedicle was still open and raw looking. It bleeds in the beginning, but scabs over and the wound heals. The antlers then become a food source for smaller animals during winter, which is why there's Wyoming laws in place that prohibit picking sheds up until May 1st on public lands. It guarantees the rich food source for a plethora of animals that depend on them over our brutal winters. Come May, people search for the fallen antlers-- which are worth a lot of money. If you're lucky enough to find a matched pair, all the better. A pair is worth the most. But because the antlers fall off independent of one another, it's more likely you'll just find one. A matched set is worth between $500-$1,000, based on size.
