Trail Cam Update

As reported in the last post, a motion-sensor Trail Cam with night-vision capability was deployed adjacent to White Pond Road Trail and focused on a White-tail Deer carcass which was found on the trail and moved off-trail by Bob K.  In the previous post the last observation was from January 17th.  Many hundreds of photos have been downloaded from the Trail Cam since.  

First, take a look at the progression of deer carcass from January 15th to February 1st:

January 24, 2014.  Carcass has been hollowed out by scavengers

January 28, 2014 (empty site/carcass gone)

January 28, 2014.  Head, leg and some hide dragged about 50 feet from original carcass site

February 1, 2014.  Head, leg, hide are now gone.  Only some fur and bone fragments remain

Likely Eastern Coyote territorial marking near the deer carcass site

Fisher tracks near carcass

Bone fragment along coyote trail leading away from carcass site along trail into thicket and woods

Another bone fragment further along the coyote trail

Plenty of fur marking the trail used by the coyotes

Here are some of the most interesting images from the last Trail Cam downloads:

Night-vision photo of Eastern Coyote.  Although it looks like he is baying, but it is suspected that Wiley is sniffing for other predators

Night-vision photo of Fisher

It could be that the two coyotes working in tandem could pull the carcass apart more efficiently. The picture above was taken just before the carcass disappeared.  Since nothing remains of the carcass, the Trail Cam at this site has been decommissioned and redeployed.  Live beaver is next, hopefully.

Trail Cam sightings were cataloged.  Its interesting that most feeding only takes place for a few minutes at a time.  Here are the data.  Note times have been rounded up or down as appropriate

Feeding on the carcass chronologically

Sorted by animal with average feeding time.  Note that the average is statistically crude but gives the picture of feeding habits.

Very often the feeding animals would disappear for a few minutes and then return.  It is suspected, in most cases, that there is general nervousness about other predators or scavengers in the area.  Raccoon wins, feeding for an average of 24 minutes with one session lasting almost an hour.

While deployed, the Trail Cam was strapped to a tree with nylon webbing and secured to the tree with a locking cable.  Before being dismounted, it was noted that the camera was significantly crooked as compared to how it was originally positioned.  There was a blurred picture in one of the last frames on the Trail Cam.  A clump of dark, almost black fur was found on the locking cable.  A fisher probably dashed up the tree and used the camera a step causing it to skew.  Although fishers spend more time on the ground than in the trees, fishers are excellent tree climbers and will use the trees for safety and escape.

Lots to talk about since the last posting. 

Bird Survey (01/11/2014)

 John Milhaven led a winter bird survey at ARNWR on January 11th; a very foggy morning

Foggy walk down Winterberry Way

  Birds were not very plentiful but there were some good sightings including: 

• Northern Cardinal
• Cedar Waxwings
• Golden-crowned Kinglets
• Belted Kingfisher [ me ;-) ]
• American Robin
• Brown Creeper
• American Robin
• White-breasted Nuthatch
• Black-capped Chickadee
• Blue Jay
• Mallard
• Canada Goose
• Tufted Titmouse
• Northern Cardinal
• Great Blue Heron
• Canada Geese
• et al.

Cedar Waxwings

Evidence of Raccoon was seen in the snow at the footbridge on Winterberry Way.  Check out the footprint along with those of duck:

Raccoon footprint is in the lower circle and the duck prints are in the upper circle

Snow melt-back revealed Vole tunnels and trails in the snow

Trail Cam

Recently a Whitetail Deer carcass was found along White Pond Rd Trail.  Bob K, one of the Refuge volunteers, dragged it off the trail into the woods.  Ranger Kizette notified Gary F who subsequently deployed a motion-activated trail camera aimed at the carcass with the hopes of identifying wildlife that comes to investigate and feed on the dead deer.  When there is sufficient light the camera records in color.  At night an infrared (IR) flash kicks in and it photographs in gray-scale tones.  When the sensor sees an animal the Trail Cam is set to take a picture every 30 seconds until the animal is out of view.  The Trail Cam has been in the field for a week now and has taken several interesting shots.  Below are sample pictures (note the date and time stamps in the lower right corner of the photos):

Deer carcass when the Game Cam was first deployed

So far five animal species have been photographed feeding on the carcass including: Fisher; Red Fox; Red-tailed Hawk; Raccoon and Eastern Coyote .  Here are some samples from the several hundred photos (remember, you can click on the pictures for larger images):

Fisher

Red Fox

In addition to animals feeding on the carcass, humans were photographed off-trail by the Trail Cam (No!  Not feeding).  Apparently they followed the fur and blood from when the carcass was dragged off White Pond Rd. Trail  (see two photos below and note that the faces have been purposely blurred for publication):

Humans

Although Common Ravens are frequently seen in this part of the Refuge they aren't feeding on the carcass.  It could be that the Red-tail, also commonly seen in this area, is keeping other birds at bay.  It will be interesting to watch and confirm this behavior.  

Ranger Kizette is keenly interested in seeing a bobcat feeding on the deer.  To date there have been neither  bobcat photos on the Trail Cam nor tracks found in the vicinity.

Tomorrow, the next set of photos will be downloaded from the Trail Cam.  If there is anything new or interesting they will appear in another post shortly.  It is apparent that the dead deer will be a feeding site for a while longer.

Come visit Assabet River National Wildlife Refuge.  Observe the rules and enjoy.

My Refuge is snow covered and very interesting now. 

Figure 1  Winterberry Way

Figure 2  Opening in snow-covered ice near footbridge on Winterberry Way

By the footbridge on Winterberry Way the water was alive with tadpoles and even small Blue-gill sunfish.  The tadpoles were very large (~4 In. in length) so it is suspected they are Bull Frog.   Some tadpoles will go two to three years before their metamorphosis.  There are many factors including water temperature, oxygenation, food availability, overcrowding, to name a few.  As the ice gets thicker and oxygen levels drop there may be mass mortalities as evidenced last winter.  But for now they are wriggling and providing me (Kingfisher) and cousin Heron with a ready food source.   Yum!

Figure 3a  At footbridge on Winterberry Way the water was alive with tadpoles and fish.

Figure 3b    Here is a magnified view of one of the tadpoles from photo 3A.  A polarizing filter would have helped

The Bald-faced Hornet’s nest that was photographed last summer and again in the fall (after being ravaged by critter(s) unknown), is now further torn apart. The comb center is now clearly visible in the photo below:

Figure 4  Bald-faced Hornet's nest showing comb cellcenter.  Taylor Way near FEMA

There are still plenty of other signs of life around me as evidenced by all the imprints and scat in the snow.

Figure 5 Canidtracks along Winterberry Way. Coyote?  Dog?

Figure 6  Closeup view of canid track

Great Blue Heron tracks were seen on the ice on either side of Otter Alley.

Figure 7  Great Blue Heron tracks on the ice adjacent to Otter Alley Trail

Figure 8  Great Blue Heron tracks between Otter Alley and Taylor Way

Two Herons were spotted.  One flew off and landed  behind the cattails.  One of the Herons can be seen If you look closely at the annotated picture below:

Figure 9  Great Blue Heron (within hashed circle)adjacent to Taylor Way taken from Otter Alley

There was a dead Blue Jay on the trail near the footbridge on Taylor Way.  It had but one leg.  There were no signs of a struggle (neither loose feathers nor blood).   It is suspected that the leg was missing well before it died.

Figure 10  Dead Blue Jay on Taylor Way near footbridge

There’s a new bench by the footbridge on Taylor Way.  Hurray!  This is one of the most interesting wildlife watching areas on the refuge.  It is tied with Otter Alley for the best birding throughout the year.  It’ll be a nice place for breakfast, lunch or snack while watching nature.  Please pack out what you pack in!  Keep my refuge litter free. 

Figure 11  New bench near footbridge on Taylor Way

There were very few ducks seen.  Generally this time of year they hang out in the open water in the marsh between Taylor Way and Otter Alley.  Only Canada Geese were seen there this time.  Numerous duck did fly by but none landed in the open waters within the marsh.

Figure 12  Canada Geese on the ice in marsh between Taylor Way and Otter Alley.  Taken from Taylor Way

Here is a complete list of birds seen/heard:

• Blue Jays (Winterberry Way & Taylor Way)
• Canada Geese (marsh between Otter Alley and Taylor Way)
• Great Blue Herons (Otter Alley)
• Eastern Phoebe (Taylor Way near footbridge)
• Goldfinch (Taylor Way near footbridge)
• Cedar Waxwing (Taylor Way near footbridge)
• Sparrows (spp?)  in thicket and unable to identify
• White-breasted Nuthatch
• Red-breasted Nuthatch
• Pileated Woodpecker (heard drumming...not seen (Taylor Way near footbridge)
• Red-bellied Woodpecker (Otter Alley)
• Mallards (fly-by only above Taylor Way footbridge) 
• Flycatcher (sp?) (yellowish breast.  Too distant to identify or photograph)
• Northern Cardinal

Hope to see you on the Refuge and wishing everyone a very happy and healthy 2014!

Have you heard of the Pine Tube Moth?  It was a new one to me!  Argyrotaenia pinatubana lives in pine trees and seems abundant in Eastern White Pine on the Refuge and well beyond too.   At this time of the year the Pine Tube Moth larva has bundled up to about 20 live pine needles with a silk it produces.  The bundle is fashioned into a tube; the binding silk on the inside of the tube.  The greenish-yellow larva (caterpillar) will eat some of the pine needles composing the tube from the tips down.  If too much is eaten it will build another tube.  Here is an illustration of a typical tube residence.

 

 

 

 

Below is is an actual Pine Tube Moth tube photographed on the Refuge.  Difficult to see unless one is looking for it.  Once you know what to look for you will find tubes are abundant.

 

 

 

As the weather starts to cool, the larva pupates in a chrysalis as is typical for moths and butterflies.  The moth will emerge in the spring.  Hopefully next spring there will be a moth picture to post.  Here is a photo of the chrysalis from an opened tube

 

 

 

According to several sources, the Pine Tube Moth is a minor pest only effecting aesthetics as the tube needles, especially the tips, will generally brown.  It is found from Canada to Florida and west into Minnesota and Wisconsin.  Jack Pine Tube Moth is a similar species found in our western states.  In some areas two generations may occur in one season.

 

I'll be looking for caterpillars in the early summer and again in the fall and moths also.  Yum!  (Yes.  Belted Kingfisher will eat insects too)

 

Hope to see you at my Refuge.

The Refuge has been quiet but still plenty of things to see and do there. 

 

Birding with John M: John Milhaven led a morning birding walk last Saturday.  Here is a partial list of sightings:

• Eastern Bluebird
• Blue Jay
• Northern Cardinal
• Gold-crown Kinglet
• Common Grackle
• Canada Goose
• Mallard Duck
• Great Blue Heron
• Black-capped Chickadee
• Tufted Titmouse
• Down Woodpecker
• Hairy Woodpecker
• Belted Kingfisher (that's me!)
• American Goldfinch
• Dark-eyed Junco (slate-colored variant)

 

Representative pictures of each of these species photographed on the Refuge can be found at: http://farnwr.org/gallery1.html

 

Bunker Tour: Jan Wright led a bunker tour last Sunday.  It started in the Visitor Center with her presentation on the history of the ARNWR land especially from the time of the government taking of the land by eminent domain in 1942 during WWII.  Residents were only given ten days to pack up and move out and construction of the ammo depot and bunkers commenced almost immediately. The site was used to store munitions from navy vessels docking in Boston Harbor and surroundings.  The ammo was removed to enhance the safety of the harbor in case of accident or attack.  It was carried by rail  to be stored in the bunkers (officially know as "igloos").  The site (now ARNWR) which touches Maynard, Stow, Hudson and Sudbury was just out of the range of enemy battleship firepower of the time making it a safer prospect than storing anywhere near the city. 

 

Following the war it served for troop training, munitions testing and numerous projects associated with the Army's Natick Labs.  Camo gear, parachutes and other materials and equipment were tested here.  Our Refuge was established in 2000 but it was not opened to the public until structures were demolished and Superfund cleanup was completed.

 

Bunker #303 was opened.  It was dark and echoey and remarkably clean and fresh smelling.  I would have expected dank!  Click on the image below to see photos from the tour.

 

 

 

 

Flora & Flora Spotted Recently

 

Deer: spotted from a distance crossing Harry's Way near Kingfisher Trail.  These were very mature does, both unusually tall.  Legs too short for moose more reminiscent of elk but there are no Elk in this area.

 

Yellow-legged Meadowhawk Dragonflies are still about, particularly around Puffer Pond. 

 

 

 

Remarkably these two are both males in mating position!  Thanks to both Betty and Jini Foster for help with identification.

 



Here's what Betty Wright has to say about Yellow-legged Meadowhawk Dragonflies:

• They are the only Meadowhawks to fly in November; the latest to fly
• They can feed at temperatures below 50 degrees
• Eyes are reddish brown
• Brown to yellow basal wing patches
• Early legs are dull yellowish; the older legs are dull brown
• Lack of black on legs and usually less black on the sides of the abdomen distinguish this species from other Meadowhawks

Here are some other comments from Betty:On Kingfisher:  I saw a Kingfisher.  This surprised me, but according to David Sibley, while they will migrate, they will stay as far North as there is open water.  Mine could have been migrating or one that planned to winter here

 

On Earthworm: There is not a native earthworm in North America.  They are all invasives and come from Europe.  I am not sure whether we are better or worse for them

On Wintergreen: When I was much younger, the advice was to chew on Wintergreen leaves.  Now, people into herbal medicines like Arthur Haines say never chew the leaves


Betty will be a frequent contributor to this blog :-).  Welcome aboard Betty and thanks!

As the weather continues to cool the waterways within the Refuge will be resting place for migrating and returning waterfowl.  Keep an eye open for Mergansers, Buffleheads, Teal, Ring-necked Ducks and others.  Come on down and keep watch.   Though the Refuge is seemingly quiet there is a lot of work going on.  Beavers and muskrats are preparing and repairing their lodges and stockpiling materials for the long winter. Watch for their activity near sunrise and sunset.  Also look for new beaver work (gnawed and felled trees) along waterways.

Speaking of muskrats, Paulette Freedman will lead a Fledgling program this Friday (22 Nov) at 10:30AM with a focus on muskrats and cattails.  Age range for this is 2 to 5 year olds and will be held in the ARNWR Visitors Center.


See you on the Refuge.
