A Few Tracks in the Snow

I love to go out after a snow and view the tracks left behind by animals going about their normal business at Blue Jay Barrens.  I’ve been wondering what animal has been digging up the mulch in my garden beds.  It looks like it has been Crows.  There has been a group of eight Crows that are always in sight of the yard.  I often see them, but they’re quick to leave if they detect any movement from the house, so I rarely get to see what they are up to.

The Indian Grass seed is supporting a variety of sparrow sized birds.  The amount of seed produced this year should be able to sustain the flocks well into spring.

The snow wasn’t deep enough to cover the Voles as they crossed the mowed paths.  Voles traveling in the open will create an unbroken path through shallow snow.

Mice normally travel through the snow in a series of short jumps.  Individual foot prints are easy to see along with a mark made by the tail.

It looks like there’s a Domestic Cat in the area.  The line of tracks is very distinctive.  You can imagine the cat as it walked along in that line.  The individual tracks are small and will show four toes and no claw marks.

Cottontails have been scarce this winter.  I only saw one set of tracks during my walk.  Excessively wet weather often has negative effects on Cottontail nesting success.  Frequent rains can fill the shallow nest hole with water and cause the young to die from drowning, exposure or illness.

Gray Squirrels have been active every day so far this winter, but their numbers are also down from past years.  The most common Gray Squirrel nest type at Blue Jay Barrens is a mass of cedar bark strips placed high in the branches of an Eastern Red Cedar.  These nests would be susceptible to moisture infiltration from frequent rains.  It’s not unreasonable to believe that a few nestlings were lost because of the unusually wet conditions we experienced during the last year.

Of course, you don’t have to go far to find Whitetail Deer tracks.  The morning after the snow showed every trail to the yard filled with deer tracks.  There were deer tracks to be found everywhere I walked.  If deer had been this numerous when I bought the property, I might have named it Deer Track Valley.

Animal Activity in Mowed Field

In the mowed field, the few shrubs left standing are really noticeable and have influenced the deer traffic pattern. The shrubs are Deerberry, Vaccinium stamineum, a relative of the blueberry. The deer change course to visit each shrub as they cross the field.

Deerberry can grow to be several feet tall if it gets the chance. It seems to be a favorite deer browse and receives a severe pruning each winter.

The deer don’t chew it down to the ground. They prefer to eat the tips of the newest growth. If food is scarce, they will begin to eat the older wood.

The tracks look as though a passing deer detoured to make a quick loop around the shrub. The shrubs respond to the loss of branch tips by producing more side branches. This results in more branches for the deer to eat the following season.

Mouse tracks were everywhere in the field. The owls must not be hunting here.

Here’s the classic tulip imprint of a mouse hopping through deep snow. These tracks are either from a Deer Mouse or a White-Footed Mouse. Both species are common in the field.

When I saw the distance this mouse jumped, I began to wonder if the tracks were from a Meadow Jumping Mouse. The tracks coming in from the bottom of the picture continue near the top. The tail imprint is rather long which is also a characteristic of the Jumping Mouse. The problem with that identification is that the Jumping Mouse is supposed to spend the winter in hibernation and should not be out running in the snow in the middle of February.
