Rubs, Scrapes and What Does The Deer See, Part Two©

It’s that time of the year and the white tailed deer (Odocoileus virginianus) are running, the bucks are rubbing trees and making scrapes. “But what does the deer see ... Ring-ding-ding-ding-dingeringeding!?”

What does the Deer See!?

Hunters used to think that white-tailed deer were colorblind, only seeing the world in shades of gray, but now researchers know that deer can see colors, just not in the same way as humans. So, what does the deer see and what does this mean for hunters and other visitors to the wild parts of North America?

Basically, rods in the retina provide coarse detail in low light situations and cones provide finer detail and color vision, containing photopigments that allow you to see the colors. The biggest difference between human and deer vision is the different number of rods, cones and the number of photopigments, pigments which convert light into color signals, found in their retinas.

Humans have trichromatic vision because their retinas contain three photopigments which allow us to see colors. The first is at the short wavelength of very dark blue-violet at 420 nm (nanometer), the second one at the moderate wavelength of green at the 530 nm range, and the third at the long wavelength of orange-red at 565 nm. Additionally, human eyes have more cones than deer eyes, while deer eyes have significantly more rods. And because of this, humans can see details and colors much more clearly than can a deer. But our lenses filter out almost all the available UV light, preventing us from seeing shorter wavelengths which are visible to many other animals, including deer.

The University of Georgia Deer Lab (UGA) has done much of the research on the white-tailed deer’s visual capabilities. They discovered that deer have dichromatic vision and that a deer’s retina only has two photopigments with just two peaks. The first one is at the short wavelength of dark blue at 450 nm, and the second at the moderate wavelength of green at 537 nm. And deer are 20 times more sensitive than humans are too blue. In fact, deer see blues much more vividly than a human sees red and can even see ultraviolet (UV) light between wavelengths of 300 nm and 400 nm. This is one reason deer can see so much better in low-light conditions than can humans. Also, unlike humans, deer’s eyes don’t have an ultraviolet filter that protects them from the Sun’s harmful rays. According to Dr. Gino D’Angelo, “The lens in a deer’s eye are perfectly clear, where ours are more like yellow shooting glasses that filter out some of that ultraviolet”.

All things on the Earth are exposed to UV light all day long, but this wavelength is overpowered by visible light. As the visible light begins to fade at the end of the day, the shorter UV wavelengths make up much of the remaining light. UV light is most abundant around sunrise and sunset, although it lingers deep into the night, and the moon and cosmic rays shed some all night long. Deer eyes have adapted to the low-light conditions of dawn and dusk when UV light is dominant, and this is when they can see their best and are most active.

What does it all mean?

Since deer’s eyes can’t see longer wavelength colors like red and orange, to a deer bright oranges and reds, look like muted grays and browns.

According to Blaise Newman at the University of Georgia Deer Lab (UGA), “Deer don’t see blaze orange the way that we do, but it’s not like you disappear. It can be very neutral, but if you don’t have some form of breakup you can look like a dark blob in the forest. So, if you can get blaze orange breakup, that’s always a good selection”.

Also, per Newman, “Deer are a prey species ... Having detailed discrimination isn’t really important to deer. They just need to be able to detect and escape something”. With a deer’s dichromatic vision limiting the number of colors that it can see, deer have less “chromatic noise”, and not having to process so many colors, allows their eyes to detect movement much more quickly and easily. Newman explains, “They see motion at an astounding rate compared to our own ability”.

To us deer vision might seem like a pale imitation of what we see, but that’s only because we’re seeing the world through our eyes. As omnivores and tool makers, we need to see in finer detail and to be able to recognize a wider range of colors.

But with a deer’s ability to see into the ultraviolet wavelengths, there are things that they can see that we cannot.

According to Daniel DeRose-Broeckert of the UGA, when viewed with a black light, fresh rubs glow more during the pre-rut, and fresh scrapes glow more during the rut, he explained that to deer “rubs look like highway reflectors ... When the rest of the woods are dark, the rubs and the urine in the scrapes are highlighted because it’s throwing a different color, a brighter color, than the light that’s contacting it”.

The reason for this is that when deer leave rubs on trees, the bark layers, saps and other plant parts photo-luminesce, and so do the secretions from a buck’s forehead gland. The wavelengths produced by the urine in the scrapes, according to DeRose-Broeckert, glow in the UV range “like spilled milk” or “spilled white paint”.

And now we know “what does the deer see!?”

And Now for Something Completely Different - The Hands Have It, Part Two ©

Author’s Note – I’m in the process of opening a fencing academy and I’m writing a syllabus and text to complement the lessons. Time is, unfortunately, limited and sometimes I don’t have time to get all the writing I want done, to meet deadlines. Hopefully, even though this is not part of my core focus for this blog, you will find it at least amusing, if not interesting.

Hand Positions One, Five and Six

Positions One and Positions Five and Six are used in making parries, although Position One is also used to form the Hanging Guard.

The First Position was called “Prime”, or “prima”, because it is the first natural position the sword hand assumes after pulling the sword from its scabbard with the tip pointing towards the opponent. This position’s main drawback is the fact that it tends to tire the arm.

Intermediate positions exist between any two adjacent of the four main hand positions. Both Agrippa and Barbasetti taught two in between positions, called ‘second in third’ and ‘third in fourth’. Agrippa in 1553 identified them as “mista” (mixed) or “bastarda” (bastard) positions.

Once you know how to position our hands you can begin to make effective cuts, thrusts, guards, parries and molinets, something we will discuss in future articles.

Don’t forget to come back next week and read “Ten Essentials of Winter Camping ©”, where we will talk about how to camp in the winter wilderness and stay warm and safe.

That is all for now, and as always, until next time, Happy Trails!

Rubs, Scrapes and What Deer See, Part One©

It’s rut season and the white tailed deer (Odocoileus virginianus) are running, the bucks are clashing antlers, rubbing trees, and making scrapes, leaving love notes to each other.

Rubs and Scrapes...

A “buck rub” is the term used to describe the scrapes and abrasions caused by a male deer rubbing his forehead and antlers against a tree. A buck will use its antlers to strip the bark off saplings, brush, small diameter trees, and even fence posts, to mark his territory and polish his antlers. Throughout this process, the bark is peeled away to expose the fresh wood underneath.

Bucks make rubs for four reasons, to mark their territory, like a signboard, to signal their presence to other male deer. To demonstrate dominance, the size and height of the male white tailed deer rubs offering clues to the buck’s age, size and health. Bucks rub their antlers and forehead on trees to leave secretions from their glands, which signals their presence and readiness to breed to other deer. And lastly male white tailed deer use rubs to strip the velvet off their fresh antlers.

Bucks rub trees with the bases of their antlers, sometimes they rub head-on, with the tree trunk between their antlers. Sometimes they turn their head sideways, dragging their antlers perpendicularly up and down the trunk.

Rubs start to appear in late summer when male deer rub the velvet off their freshly grown antlers. Early in the season it’s to remove velvet covering their new antlers. Some bucks don’t worry about rags of velvet hanging from their antlers, but others are obsessed with rubbing off every strip. Some bucks clean the velvet off their antlers quickly, others take longer.

During the autumn mating season, or rut, and on into early winter until the antlers drop, the bucks will continue to make rubs, since after the velvet is shed a buck’s testosterone levels increase, and that brings with it frustration, anger and aggression. Some believe that bucks rub trees to blow off steam, but it’s also a practice for fighting, and the trees become training dummies. The rubbing helps strengthen head, neck and shoulder muscles needed for fighting.

When a buck rubs its antlers on trees or saplings, secretions (scent and chemicals) from its preorbital and forehead apocrine sweat glands, as well as the nasal and sometimes even salivary glands, are left behind on the exposed wood. These secretions left behind on the exposed wood of the rub communicate messages to the other deer The size of the rub usually varies with the size of the deer, with the bigger and older the bucks, leaving rubs higher up on the tree.

While single “buck rubs” don’t tell you much, rub lines with consistent rub orientation do. Normally, the direction a rub faces is the direction from which the buck approached. If numerous sequential rubs face in the same direction, this tells you the general course a deer is taking in travelling from one location to another.

To mark areas they regularly pass through bucks will make scrapes, often occurring in regular patterns known as “scrape lines”. A scrape is made when a buck paws the ground with its front hooves to expose bare earth. As the buck scrapes the dirt, it deposits secretions from the interdigital glands found between the toes of each hoof. Scrapes are mostly oval-shaped and are often found with a sapling or tree branch hanging out over them. This overhanging branch or sapling is called a “licking branch”. When the buck digs the scrape, it will rub its forehead and pre-orbital glands on the licking branches to deposit scents and chemicals. And once it has scraped up the earth under the branch, the buck will urinate into the scrape with the urine passing over the tarsal glands located on the inside of each of its hind legs. When a doe nears its estrus cycle, it will also urinate in the scrape, alerting local bucks that she is or will soon be ready to breed.

Scrapes and rubs, are called “sign-post markings” and are an obvious way that white-tailed deer communicate. Although bucks do most of the marking, does visit these locations as well.

But there is more to these markings than meet the HUMAN eye because deer see farther into the UV spectrum than humans do.

Don’t forget to come back next week and read “Rubs, Scrapes and What Deer See, Part Two©”, where we will talk about what deer see and what it means for hunters.

That is all for now, and as always, until next time, Happy Trails!

“Nails up” ... “Palms down” ... Quarte or is it Carte? ... First, Second, Third and Fourth Position? ... What does it all mean?!

Fencing masters of the late 18^th through the 19^th centuries often assumed that you knew what they were speaking of, and if you didn’t, it can be hard to decipher their writings and understand the correct position that your hand must take when attacking or defending with a sword. But when I first started exploring historic sword fighting of the late 18^th and early 19^th centuries, pre-internet, some forty some years ago, questions like these were hard to answer. It took me months, and quite a few inter-library loan requests from collections world-wide, to answer these questions.

There are between six and eight hand positions possible in sword fighting, whether you are using a foil, a rapier or a broadsword. These positions are all defined by the positions of your fingernails, palms and forearms.

The early Italian system, taught by Camillo Agrippa, of Milan, and the later system taught by Maestro Luigi Barbasetti, both had four primary hand positions and two intermediate hand positions.

The four hand positions move in a circle from First Position to Fourth Positions as you turn your fingernails, palm and forearm to face upward (supinate), or you turn your palm and forearm to face downward (pronate).

Hand Positions Two, Three and Four

Positions Two, Three and Four are used to make cuts or to form the Outside, Inside or Medium Guard.

In the Second Position your sword hand is pronated and to the outside, with the palm of the sword hand down. In this hand position the blade’s “true edge”, or cutting edge, faces to the outside line.

In the Third Position your sword hand is neutral, neither in a pronated or supinated position and below. The third hand position was called “terza” and is made with a knuckles-down position of the sword hand, the true edge facing downwards. This is a hand position half-way between the Second and the Forth position and is the least tiring of the positions.

In the fourth position or “quarta”, your sword hand is supinated, and to the outside, with the palm of the sword hand up.

Don’t forget to come back next week and read part two where discuss Hand Positions One, Five and Six.

That is all for now, and as always, until next time, Happy Trails!
