May 7, 2017

The cool, wet weather that has engulfed much of the country this week has certainly slowed the progression of spring.  As of today there is still barely a hint of lemon-lime below the low clouds hanging in the hills of New Hampshire's Lakes Region.

Some of the early flowering trees are putting out their blossoms regardless of the weather, and it being so cool we should be able to enjoy them longer than usual.  Dogwood, Hobblebush and Honeysuckle all made their debut this week.

I also saw an interesting tree that I had never seen before, and it took me a long time to identify it.
The beautiful yet greatly conflicted Boxelder (Acer negundo)

I finally determined that it is a boxelder.  It seems to be a rather conflicted tree, called an elder, considered a species of maple, and with multiple common names that reference three different type of trees:  boxelder, boxelder maple, maple ash, and ash-leaved maple. [Ref:  Wikipedia]  The boxelder is not indigenous to New Hampshire but has been naturalized here and planted frequently as a shade tree due to its fast growth.  [Ref:  "Eastern Forests," Ann Sutton, Knopf, Inc, 1985]

Along with the budding trees come the insects that feed on them.  One of the prettier ones is the aptly named Spring Azure.

We saw several along the Winnipesaukee River Rail Trail between Tilton and Franklin.  It's a pretty blue butterfly when airborne and the inside of its wings are exposed, but when it lands it becomes almost invisible, even if it lands right by your foot.  Or, maybe, on your foot.

It's a common butterfly this time of year in many habitats from woodlands to clearings to roadsides, and it feeds on the early flowering trees such as dogwood and viburnum.

With the spring runoff the Winnipesaukee River was raging with rapids.

Unfortunately, there are some less savory characters that also arrive to feed on the trees, including the Tent Caterpillars, which are plentiful now.

Plants aren't the only victims of the arriving insects - mammals, including humans, are subject to the tiny deer tic (though actually arachnids, not insects) which have made their presence known.  These are so tiny it is best to use a proven bug spray on your shoes and clothing when you're out.

There has been a sighting of our banded female loon, and I just received an update from the Loon Preservation Committee saying that no, the banded loon seen earlier this spring on Lake Massebesic (see April 23 post) was not our loon.  But it is great that our pair has now returned!  They took a fishing tour through our end of the lake on Saturday, when I saw them for the first time.  But for several days prior a single loon, likely the same one that's been on the lake for three years now, has been living in the cove.  We watched it groom itself in hopes of looking sharp to a potential mate.
Be careful with that beak!


I took some video to show how it travels around in circles as it paddles with one foot while grooming its underside.

And after all that hard work, a nice nap was in order.
A quiet afternoon means nap time on Lake Wicwas

I'm sure the trees are about ready to explode at this point, and just one warm sunny day is all it will take for them to burst out and paint the world green again.

Memorial Day 2016

Memorial Day brings a time to give thanks for all we have in this country;  it is so easy to forget the sacrifices so many have made for us.  This grave of two revolutionary war veterans is barely visible from Chemung Road, but is well maintained.

The hot weather this week set the stage for quiet early-morning paddles on Lake Wicwas.  On two occasions I watched Baltimore Orioles enjoying the fruits of spring on Sheep Island.

They were hopping from branch to branch, plucking off delectable, energy-rich insects from the pine trees. 
Where is it hiding?

There it is
Yum!
This a synergistic service, removing damaging pests from trees while nourishing themselves, keeping nature in balance.  Orioles are known predators of tent caterpillars, and this seems to be big year for those unsightly insects.

Tent caterpillars may completely defoliate a tree, but unless it is otherwise stressed, the tree will usually sprout new leaves and survive.  I've seen a scarlet tanager frequent the vernal pool where this nest is located.  Many other animals feed on these caterpillars as well, as unlike the non-indigenous gypsy moth, tent caterpillars are native to New England.  A Michigan study by the Conservation Resource Alliance found that on average, one bear eats 25,000 caterpillars in a single day!   (They determined this by sifting through their scat - how's that for a job?)

If any nests are built over the lake, and a caterpillar should fall onto the water, these guys would be sure to gobble it up!  (This one's for you, GameFisher316!)

After depositing her eggs, the female bass will depart, possibly placing more eggs in another nest with another male;  this increases the odds of passing on her genes.  The male will stay at the nest to guard the eggs and protect the minnows when they hatch.  At least until he gets hungry - then he will likely eat plenty of his own young.  [Ref:  William K. Johnke, Dorbil Publishing Co, 1995]

If you were out around the lake this weekend you probably saw lots of flowers:  lilac, cherry, jack-in-the-pulpit, and everyone's favorite, lady's slippers.

Now an update on the loons:  they still appear to be in search of the perfect nesting site, as the pair remains together, out fishing and doing home inspections.  Early Saturday morning one popped up near me to say good morning.

And there is good news and reason for optimism:  on Pleasant Lake, 30 miles southwest of Wicwas, the loons have re-nested after abandoning their first nest due to eagle harassment.

Finally, Meredith Center held a Memorial Day service at Oakland Cemetery today to once again remember, on this Memorial Day, all those that served and sacrificed to secure our safety and freedom. 



Thank you.  We remember.
