Green With a Hint of Black Bear

We were both patient with each other (and ourselves).

He snorted a few times, probably saying "Human, let me do my thing!".  So I listened, and respected him, just as he did to me.

We didn't provoke each other.  Yelling, running, and bluffing was not necessary.

The only thing that was necessary was both of us seeing each other there and leaving each other alone.

The animal really only wanted some acorns in the tops of the trees, just as most bears in the area are doing right now in the year.  They're getting some extra calories, as it is still fairly hot during the day, and they know that winter will be here before long.

Bears in Northern Virginia

Putting the terms "bear" and "Northern Virginia" in the same sentence always seems to stir people up.  It's really not at all what I intend to do, in fact, I would really prefer to do the exact opposite.

Like something out of a horror story, some people around here are absolutely terrified by black bears.  Other people are in shock to hear about them roaming around suburban neighborhoods in Loudoun and Fairfax counties.  There's a whole mix of emotions that come into play, and people sometimes come to me to ask what emotion they "are supposed to have" or how they should react.

I find the interest and intent that people have with their native and local black bears absolutely fascinating.

There a tons of wildlife agencies that may possibly handle, talk to you about, or give advice on what to do if you see a black bear, and for the protection of my jobs and my sanity, I will not be going into much detail here about those organizations.

What I will do though, is provide you with information about some bears that I've seen.  I'll show you pictures and tell you cool stories, and immerse you into the world of northern Virginia's largest living mammals.  I'll do this on this blog post, and more in the future.

Let's first look into a common question that people have for me; the question: "Where are the black bears around here?"

My answer:  "All over the place, as they can be anywhere and everywhere and have very large territories as compared to other local mammals"

Seriously though, I've seen black bear sign (scat, tracks, fur, and/or actual sightings) in every northern Virginia county that you could think of. 

One of the most interesting bear tracking episodes came out of Loudoun County, Virginia this past winter.  A bear was seen multiple times on private properties, crossing traffic, and really all over the place.  I'll keep the exact locations to myself for now, but this bear had a very specific territory in mind.   I spent a good amount of my spare time tracking it through woods and fields, and even managed to see it a few times.  One day, I followed the tracks for over 3 hours, and even then, there was no end to its walking in sight.  The tracks lead to and were on top of large fallen logs, across streams, onto an icy pond, straight over barbed wire, and even into a bedding area where it probably stayed during that same day.

To put it simply, this bear seemed to have almost no problem going over and across all these obstacles, as the gait in the tracks seemed to almost always be consistent over short distances.  In the long run though, I could tell where it "picked up" its pace and almost did a galloping-like motion and could also tell when it got near potential food sources, as it would stand on its hind legs, walk a few steps, then go back down to all fours.  I think that it did this as if it was smelling the air more closely each time it neared a garbage can or bird feeder.  Bears will often stand on their hind legs to get a better look at something with their eyes and to hone their sense of smell when their nose is a few feet higher when standing.

Speaking of bears eating, it is actually illegal to feed black bears in the entire state of Virginia.  For more information on this, visit this website Living with Black Bears in Virginia .  That site also has various other information for the state of Virginia regarding black bears.

So with all this information in mind, I'll lead everyone to another common question that people ask me:  "If you can't feed black bears in Virginia legally, then how do you get them to come near the camera?".

This question has tons of answers, none of which lead me to feeding black bears.  A really good way of getting bears on camera trap is to just get lucky and have one walk in the field of view of the camera.  It's kind of an answer that most people who camera trap do not want to hear, but it really does work if you put out enough trail cameras or have a lot of patience.

Another answer to that question might be to set up a camera trap where other animals are living and eating.  For example, a recent camera trap bear sighting around here came from this incidental capture.  The camera was actually pointed at a tree to see what woodpeckers would come near the freshly carved woodpecker holes, and boy did the woodpeckers arrive.  Though, a bear did too.




Why is this? 

It's almost like the bear could have been targeting this tree just because the woodpecker might have had success in getting insects out of the tree too.  Do black bears know to specifically seek out fresh woodpecker sign so they can also get a bite of insects?  I'm not sure about that one, but hope to find the answer sometime.

If you ever see a bear or bear sign in northern Virginia, I would like to know.  It could really help me track these carnivores better, and ultimately might even give me some basis on making a more accurate estimate of the black bear population in these counties.

Look for holes in trees that are this size.
What I would really like to do next year, is do a large camera trap survey just on black bear dens.  I've heard rumors and know of a few in the area that are actually confirmed by various biologists, but would like to expand on what most people (me included) already know.

I'm looking for holes in trees that could easily fit a person, brush piles where you think a bear could be, old barns where a bear has gotten into, and of course, any place where you have actually seen a bear sleeping.  Even though it is months in advance, I would still like to know. 



Please and thank you!

Wildflowers of Northern Virginia's Early Springtime

I left for a short hike today to check a camera trap (with minimal results) and eventually found myself taking a detour on some trails where I knew there were some interesting wildflowers.

Yesterday before work, I did the same and found a plethora of beautiful photo opportunities.  Although I have only been using my cell phone's camera to capture these, I feel that the photos have turned out pretty well.

These flowers are mostly ephemeral, which means that they only bloom and "come out" for a very short time.  It really depends on the species, but some of them are only in bloom for a period of multiple days to a few weeks.  There are so many more than the ones that I have seen and posted on here, but those will have to wait for another day.

I hope you all enjoy looking at these.



Virginia bluebells nearing peak bloom.  Fairfax County, VA
Virginia Bluebells (Mertensia virginica) are just about in full bloom in various locations in Loudoun and Fairfax counties.  They seem to be a real staple for people doing wildflower walks along the Potomac River and other flowing water bodies.  In some places, they come out in the tens of thousands (or more!) and can be a breathtaking sight. 

To see them in Northern Virginia, look near sandy/muddy areas in parks or private lands (with permission, of course).

Dutchman's Breeches.  Fairfax County, Virginia


Dutchman's Breeches  (Dicentra cuccularia) are some of the most interesting ones in the area.  Look at the shape of those blooms!

It's not a complete rarity in the area, as some people may believe, but to find it can be a bit tricky.

In a general sense, an easy way of finding these may be to look where bluebells are also blooming, as they tend to prefer similar soils and forests.  They can be found in other places though.  The "breeches" in the common name refers to the similar shape of sort of pants worn years ago.

Northern Virginia's beautiful sessile trillium.
Sessile Trillium (Trillium sessile) is another really interesting looking flower that inhabits Virginia. 

To me, it's interesting to see brown in a flower (pictured in the center of the flower), as a lot of other flower species on the ground that people commonly see are brightly colored.

I found a few here and there along the Potomac River a few days ago, but came upon a few large patches eventually after looking for a while.



Spring Beauty (Claytonia virginica)  is one that never seems to get past my eyes when I'm out and about in the woods this time of year.

It's all over un-mowed lawns, deep forests, and even near the Potomac River.  It can be hard to miss in places, as there are patches of it where individual flowers range in the thousands.  It's no wonder that it's called "spring beauty" as it is a wonderful sight to see after a long winter like the one we had this past year.  Each petal is streaked with a darker pink or purple color, and it can be fairly easy to identify.  Look for these in basically any wooded area in Loudoun or Fairfax, and you have a decent chance of finding them.

New Dens

Newly dug fox hole.
The better part of this afternoon was spent working and scouting locations for where I should put up camera traps next.

Through some dense brush and "the thick stuff", I stumbled across a new den site, of the fox variety.

One impressive entrance hole was made deep into the little berm where the dens were being made.  An exit hole was only just beginning though, and was no more than 3 days old.

Hopefully we'll be seeing some fox kits within the next two months.

Camera traps will tell us all this though, but for now, I'm going to stay away from this den so I do not disturb the animals that are building it.

Last year brought some incredible results from fox dens that not only helped estimate the canid population, but gave me a great opportunity to educate the public on what some cute northern Virginia baby foxes looked like.

See the link here to view some results from last year's red fox den and its activity:
Red Fox Kits 2014

There's no telling what will happen though.  Time will tell, and that is the beauty of all this.

Red Fox Rendezvous



I am putting the final touches on some graphs, charts, and tables that show the results (and how-to's) of my red fox survey between the months of this March, 2013 and March, 2014 in park lands and private lands of Northern Virginia.

Results include current living foxes, foxes that have been hit by cars (or died by other means), foxes that have moved out of the area, and fox kits

Here is a very watered-down and simplistic version of my data:

In a 24 acre plot, there were 3 individual red foxes

In a 60 acre plot, there were 4 individual red foxes.

In a 350 acre plot, I've found that there were at least 7 individual red foxes.

In a 430 acre plot, there were 9 individual red foxes.

In a 600 acre plot, there were 9 individual red foxes.


I get this data by comparing camera-trap images of different cameras set up in each park.  A red fox that appears at one camera (under normal circumstances) cannot be the same red fox that appears at another camera 1 mile away, 30 seconds later.  BAM!  That's two individual foxes.  Some red foxes look completely different from eachother, others are a little more difficult to recognize.  Figure in more parks and a heck of a lot more cameras, and results like this pour in to my computer on a daily basis.

Happy Thanksgiving!

There's no way this blog is having a Thanksgiving themed post without a picture of a camera-trapped, wild turkey.

Happy Thanksgiving, folks.
