Fooled and Fooled Again

While a lot of the camera traps that I use are for scientific surveys and owned by parks, nature preserves, and various parks/wildlife agencies, I tend keep a bunch for myself that are owned by me.

These ones are moved often, as they do not fit into a scientific proposal or specific project.  It's a sort of freedom that I really enjoy.  With these though, I like to challenge myself to get really cool stuff coming across the cameras.

This year, I've been all about the fox dens.  Last year's fox kit pictures and blog posts turned out phenomenal and I'm really hoping I can get something similar this year.  It takes a lot of work and time to search for fox dens, but it could prove to be really useful in the end.  Emails and messages have been flying around like crazy and many miles have been walked, in search for the holes made by these small canids.

There always seems to be a bit of a debate as to whether a hole or den site belongs to a fox or a groundhog, and while I've spent the past few years studying them, reading up on them, and tagging along with others in the field with various animal dens, I still have not perfected the art of determining what is a fox den and what is a groundhog den.

The phrase "Brian, you should know this stuff."  commonly pops up into my head, upon visiting each den site.  It's interesting though and makes this sort of fun.

Don't worry though, I know the "textbook" definition of a fox den and a groundhog den, but that is just what it is.  Generally, groundhog dens are a bit differently shaped than fox dens and dirt may be thrown out of each hole in a different pattern with each species.  They both can be commonly built on berms or small hillsides either in the middle of the woods or in meadows.

To me, the easy way to tell if a fox has been in a den is to put my face near it and take a whiff of the air.  If it smells like fox urine (a pungent smell that is similar to skunk spray), a fox has usually been there.  To make this even more complicated though, is to add the fact that a fox could have been hunting a baby groundhog, co-habitating (living with) the groundhog, or just marking the territory nearby.

I've been fooled with this time after time.  This year has been the epitome of me getting fooled by foxes and groundhogs, and just when I think I've got an active den with fox kits, a groundhog will appear.

It's a bit discouraging, but it's all part of camera trapping.

The Best Fox Kit Pictures So Far

The red fox kits in Fairfax County are still as active as ever and are growing fast. These are the same ones that I've been blogging about in the past few weeks.

Like human children, their daily activities consist of eating, pooping, and playing, without a care in the world. Must be nice!

They've been eating on their own and don't seem to be with their mother as much already.

Here's some stills of the red fox kits of Great Falls, Virginia. . .

. . . and of course videos!

One thing to take note of though is that one of the kits has a fairly large rash on its throat and neck.  It's a patch of red without fur (picture below).  Look closely at its neck to see what I mean. 

What do you think caused this?  Possible explanations that I (and other biologists, naturalists, and friends) have thought of is heat rash, scratching, mange, mites, fungus, disease, foul play between foxes, the mother red fox carrying the kit, or another predator.

I'll be watching these kits closely, and hope you will too.

Fox Kits, Fox Kits, Fox Kits

There are now two cameras at the active fox den in Great Falls, Va.  One camera is for pictures and one is for video.  That's right VIDEO of the bundles of joy!

Immerse yourself in a maximum level of furry cuteness.

Don't worry, there will be more to come.  I'm keeping a close eye on these kits.

Denning Season

It's denning season for the canids of Virginia.  That means that I'll be spending some time tracking fox, coyote, and other footprints through the mud and snow to help me find these dens.  When I find one, a camera will be going up.

Here's a good one that I found yesterday.  You can tell by the amount of footprints and kicked dirt around it that it is very active.

I used extreme care and caution not to get too close or disturb the animals that may be living in there.

Here's to hoping for pups or kits of fox or coyote this spring!

Foxes During the Day

Even though this part of Virginia has been facing temperatures in the single digits lately, the red fox foxes are jumping in front of the cameras in the daytime more than ever before.

Why is this? Well, I think there are two reasons.  

Here's the first reason:

Foxes don't like to be around humans, at least for the most part.  They tend to shy away from us and that's the way it should be.  

Since there are less people walking around parks (or other places that I have cameras) during the winter, foxes may be more comfortable with coming out in the day.  

More foxes out during the day means more chances of camera-trap images of them in the day.

Here's the other reason:

Winter this year has been cold.  Very cold. For the past few days, temperatures have barely been able to make it higher than the 20 degree fahrenheit mark.  

These temperatures have been warmer than nighttime temperatures, which have gotten as low as 2 degrees. 

Foxes would prefer to be out in the warmer part of each day than out in the middle of the night.  This increases the chances of getting red foxes on camera in the daytime as well.

Most Likely a Fox, Right?

17 out of 19 people so far say that this young mammal is a fox.  The other 2 people say a young coyote in its summer coat.  These people are all wildlife biologists, wildlife conservation specialists, or outdoor park managers who have lots of experience with both animals, so I enjoy their input and find it very interesting.

Personally, I've got my money on it being a young fox.  The tail does seem to have darker edges and a dark tip, which is common of a coyote though.  An attempt to persuade me to calling it a coyote was made based on the size and shape of the ears, and how a coyote would be this skinny in summer due to it losing a lot of its winter coat, but I hold my ground and still call it a fox.

Whatever it is, its a skinny one and was captured on camera in Fairfax County, Virginia.  The camera was reset and is still at the exact same spot.

Do you agree with me and say that this animal is a fox? Or do lean towards it being a coyote?
