Velvet Bucks

Antlers are unique among mammalian structures because they are the fastest-growing bone in the animal kingdom. While growing, they’re covered in a fuzzy skin called velvet, which contains blood vessels, nerves, and nutrients that fuel rapid growth.

Scientists study velvet antlers because they are a rare example of a mammal regenerating a large, complex organ each year—making them a model for regenerative medicine and bone growth research.

From the trail camera trap line there are velvet bucks....

 


Including this dandy boy...

Mama And The Twins

There's always some uncertainty in identifying individual deer; nevertheless this is the same general location about a month apart.

The twins are growing; rapidly...

Daily Dose

It's not just me; social media - Face Book in particular - is a vessel for disgruntled and aggrieved individuals.  Fortunately, they are in the minority.  Nevertheless, a waste of valuable bandwidth.  Clickbait.    

Since the beginning of this year I have endeavored to be a better person.  Not a Mother Theresa - just better.  And as a consequence I truthfully don't have very many grievances.  I have opinions and am not hesitant to speak truth to power; but that's not the same as full-blown grievance.

As a public service and in the interest of spreading positivity on the interweb here are some recent trail camera photos from our woods.  

A daily dose of happiness and cuteness....

Three Is a Charm

What are the odds

Ran the trail camera trap line recently and downloaded this gem. 

I have previously captured trail camera images of triplet fawns (including mom) in 2014, 2019, 2020, 2021 and now 2025.  Go ahead; type fawn triplets in the search feature in the upper left corner of the homepage.

Daycare situation or the real deal?

Fingers-crossed to catch a pic of all three with mama....

Is it just me or does social media seem to have an overabundance of grievance?

Strategic Alliance

If you spend as much time as I do napping in a deer stand or turkey blind one of the observations made during a hunter’s waking moments is that deer and turkeys sometimes hang out together.   It’s not all the time; yet, it isn’t a rare occurrence either.

The proximity of a flock of turkeys to one or more deer doesn’t scare-off the whitetails and the presence of the deer doesn’t seem to bother the birds.  By all outward appearances they seem to enjoy the company of one another.  What might be the explanation for this curious wildlife behavior and what seemingly might be a symbiotic relationship?

Wild turkeys both see in color and their vision is incredibly advanced – possibly three times greater than that of a human with 20/20 vision.  Since turkey do not sport external ears their field of view is 270 degrees and they can detect motion a hundred yards distant.  Turkeys move about in sizeable flocks resulting in dozens of vigilant eyes.  Inasmuch as turkeys will immediately begin to distance themselves from any movement they conclude is suspicious whitetail deer place their trust in the instincts of their turkey pals and follow.

Similarly, it is the sniffer of a whitetail that is incredibly advanced. I’ve been busted by a deer that winded me long before the animal ever had an opportunity to detect my presence visually.  In a group setting, if a deer goes on high-alert as a consequence of a whiff of danger the turkeys place their trust in the instincts of their whitetail pals and follow.

This photo - one of about a dozen taken over a period of twenty minutes - of a whitetail doe and fawn, accompanied by a wild turkey is likely further evidence of this symbiotic relationship.  

So, if you’re driving down the road some day and you spy a flock of turkeys keeping company with a doe and her fawns or any collection of whitetail deer there’s an explanation other than mere coincidence.

Some biologists have concluded that each species trusts the other’s best sense for their mutually-assured security.

Beauty Contest

 

As the days have grown longer the hormonal levels of whitetail deer began to change.    

Fawns are born, antler growth commences as testosterone levels increase for the boy deer and for all of the whitetails the gray winter coat with its thick guard hairs is shed and the ruddy red heat-reflecting summer coat is revealed.   

The process is complete now and you cannot miss the deer highlighted against the lush green clover and alfalfa of the local farm fields.           

These daylight-influenced hormone levels occur twice a year to trigger the spring molt and after only three months, is supplemented by the regrowth of the extra layer of longer, stiffer, hollow hair over the softer hair closer to the skin.

Mangy Deer

This animal looks a bit mangy but it's probably just scruffy.   


As the days grow longer the hormonal levels of whitetail deer begin the change.  For boy deer testosterone levels gradually rise.  As a consequence antler growth begins and the gray winter coat with its thick guard hairs begins to molt.

Hormonal changes bring about this process twice a year and deer alternately grow a faded gray coat consisting of longer guard hairs for winter-wear and replace it with the rusty red-colored coat of summer.  The summer coat will only last about three months before the critter begins to regrow the extra layer of longer, stiffer, hollow hair over the softer hair closer to the skin.  

Until the transition is complete the local whitetails are going to continue looking a bit raggedy.

Pre Rut

There are a number of locations on our property where you can predict the arrival of a deer scrape almost to the day. Last Saturday doggo and I were out hunting ringnecks when we decided to check several of those spots for any activity.

Sure 'nuff, and right on time, at the bottom of this photo (arrow) is a recently started scrape.  At the top of the photo is a horizontal branch of an oak tree just to the left of the photo frame.  This is called a licking branch.  Licking branches are located directly above a scrape. 

If you encounter a whiff of deer pee redolent in the autumn air look carefully beneath any shoulder height tree branches close by.  You may locate a bare patch of dirt in the turf that is trampled with deer hoof prints.  This is called a scrape. 

Bucks create scrapes by using their hoofs to dig at the ground. Once the soil is stirred up, they urinate on the scrape.  Bucks don’t pee the way we do.  We try to keep it off of us.  Bucks actually try to pee on their own hind legs.  The object is to hit their tarsal glands in an effort to leave their scent on the scrape.  Every deer has its own unique bouquet and the tarsal glands hold concentrated amounts of that spoor.  About the licking branch - a tree branch will hang above the cleared out soil. Bucks will rub their forehead glands on it and will also lick it with their tongue. 

The earliest of scrapes that begin to appear in October are few and far between and used principally to communicate as bucks begin to leave their bachelor groups and stake-out their territory.  It is akin to posting a no trespassing sign on a property line. 

Scrapes serve much the same function in the whitetail world as a mailbox post or a fire hydrant does for dogs.  Scrapes are meant to show dominance over a territory but are normally used by more than one buck.   

Very soon the scrape will be used to communicate breeding readiness.

Mr. Buck

There's a pretty good chance that by the time you view these photos the velvet on these antlers will be gone.

Anywho, there are some dandy buckaroos around these parts.

If you're careless you might catch a case of Buck Fever....

The Big Fibroma


On July 7 I scored some photos of a whitetail with a pendulous tumor.

Looks gross, eh?

I emailed the pics to a biologist I know who heads-up the UW School of Wildlife Biology in Madison to see if she might shed some light on the subject. She shared them with the DNR’s Chief Veterinarian.  Here’s the response back:
 
Hi all-
 
While I can’t make a diagnosis from a picture, the image would be most consistent with a fibroma. They can vary greatly in size and shape. Usually they’ll eventually regress. Sometimes that can be irritated by injury or insect bites but again that is self-limiting most of the time. These fibromas are just a lesion of the skin and caused by a deer specific papillomavirus.

This showed-up on a trail camera last week.  Looks like it's improving all on its own...

Diagnosis

 

Looks gross, eh?

These images showed-up on a trail camera recently showing what appears to be a pendulous tumor on an otherwise healthy-looking whitetail.  Curious, I forwarded them to a biologist I know who heads-up the UW School of Wildlife Biology in Madison.

She shared them with the DNR’s Chief Veterinarian.

Here’s the response back from the doctor:

Hi all-

While I can’t make a diagnosis from a picture, the image would be most consistent with a fibroma.  They can vary greatly in size and shape.  Usually they’ll eventually regress.  Sometimes that can be irritated by injury or insect bites but again that is self-limiting most of the time.   These fibromas are just a lesion of the skin and caused by a deer specific papillomavirus.  More info can be found here: https://dnr.wisconsin.gov/topic/wildlifehabitat/disease/Deerfibroma

These are  deer fibroma, or warts, and generally disappear as the animal mounts an immune response and do not present a health risk to humans.  The meat is safe for consumption too. Michigan DNR also hosts a detailed webpage on the subject here: https://www.michigan.gov/dnr/managing-resources/Wildlife/Wildlife-disease/WDM/deer-fibroma

Break Time

From trail camera three there was a bazillion photos.  I'm exaggerating.  Something on the order of 650; far more than the usual 300+ captured over a period of a couple of weeks.

That is because a solitary doe decided to bed-down directly in front of the camera for more than an hour (check the time stamp) and record several hundred selfies before getting-up and moving-on.


This has happened several times before.

The animal isn't actually sleeping.

Just taking a pause for the cause....

2024 Graduating Class

Some of this year's new recruits.

Fledgling orioles coming to the feeders to be fed my their parents.


And mama whitetail tending to her fawn.

Before and After

 

As the days have grown longer the hormonal levels of whitetail deer began to change.   

Fawns are born, antler growth commences for the boy deer and for all of the whitetails the gray winter coat with its thick guard hairs is shed and the ruddy red heat-reflecting summer coat is revealed.

One month between these before and after images.

Seeing Spots

Fetched the memory cards from the trail camera trap line the other day and I'm happy to report a healthy collection of whitetails; and an impressive class of 2024 recruits...

Schnee Hirsch

Literal translation - Snow Deer.

From a snowy morning last month there was a herd moseying along the trail covered by the video trail cam.

How many can you count?

From another camera near-by there was this.  Until they shed their winter coat the superb insulating qualities of the outer guard hairs allow the snow to collect on the animal without it melting.  

Marvel of adaptation the whitetail is...

Alarm!

No mistaking the alarm response in the whitetail deer.  It's that raised whitetail waving good bye.

I haven't a clue was spooked the deer in these photos ; nevertheless, every deer hunter I know can commiserate after being busted...

They Walk Among Us

Doggo and I ran the trail camera trap line recently and uploaded a nice collection of (drum roll please) digital photos of whitetail deer.

Yes, despite a successful hunt here at the Platz, and everywhere else based on my anecdotal and observational discussions with neighbors there are sufficient deer on the landscape to continue hunting thru January of 2024 and continue to propagate the species for the rest of my natural life expectancy.

Sunday morning we woke to a couple inches of white stuff and there was this....

Brown Velvet

From the trail camera are some nice shots and a video short of a few of the local bucks sporting their antlers as they grow.

Velvet bucks they are called.

 


I've started brushing-out our three and a half miles of trails so that at least two more deer stands can be assembled and placed in strategic locations.

Got deer hunting on my mind.
