April 28, 2019: Ice Out (on April 23rd)

We arrived home yesterday from our trip south to find Lake Wicwas had transformed from a block of ice to sparkling water, a most welcome sight!
The first waves in four months

Ice out was declared on April 23rd, though there was no report from Marion Cove which is often the last cove to be free of ice, so it could have actually been a day or so later, but with no report from there, April 23rd is the official date.  On the prior day, another observer saw the first loons on the lake.  It's not known yet if they are the local residents or just passing through, but loon calls have been frequent since then.  And within 24 hours of our return a host of spring activity proved life has returned to the lakes.  First was a pair of beavers on their daily reconnaissance of the lake.

And these busy rodents are already chewing their way through the shoreline forests.

The beaver were soon joined by a pair of buffleheads diving in the cove and the sound of osprey off in the distance.  Then this morning the osprey made an appearance, loudly announcing their arrival with their distinctive cheep-cheep calls.
The osprey have returned from their own trip south to Central or South America

There was a pair soaring overhead, circling around and occasionally landing in a tree. 

This is not the behavior I typically see for osprey which are usually watching for fish from a branch hanging over the lake, or flying with a mission on a straight line from one point to another.  This could be an existing pair getting reacquainted, or possible a new pair checking each other out.  According to Stokes [Stokes, Donald and Lillinan, 1989, A Guide to Bird Behavior, Vol III:  164-172] pairs do not winter together, but both return to their prior nesting site with the male usually arriving first.  Upon return a mating pair may circle in the area of the nesting site before exhibiting other courtship behavior including the dramatic "Sky-Dance" where a bird flies up several hundred feet, sometimes with food or nest material in its talons, before diving down and swooping up to repeat the exercise.  I'm not expecting there is a nest site near by, as I have never seen osprey nesting in the area;  maybe this is a pair establishing their relationship.

There are also a few signs of spring appearing in the plant universe.  The leaf buds on the black cherry are pushing out tiny leaves, as are red maples in the warmer locations, mostly near water.

 Soon the tree tops will be filled with the colors of the spring foliage season.

It encourages me mightily that within 24 hours of returning I saw such variety of life simply by observing what's around me.  We are so fortunate in New Hampshire to have many people that are committed to keeping a bit of our planet a suitable home for the life that was here long before we arrived.

April 21, 2019: Happy Lowcountry Easter!

We were away this past week enjoying some warm southern hospitality in South Carolina, so I don't have much to report about the status of life in New Hampshire this week, but the ice is starting to break up on Lake Wicwas, and the latest prediction from Emerson Aviation is for ice-out on Winnipesaukee within the next few days.  When we left New Hampshire it was snowing,
but when we arrived in South Carolina, it was a completely different world.
No ice, green grass
Ducklings and goslings had already hatched out.
It's amazing what a difference 800 miles can make.

I always try to visit habitats in climates that are completely different from New England, and a great contrast is the swampland of the Lowcountry.
Knees of cypress trees grow upwards from their roots in the swamp;  their purpose is still unknown

It is so flat here that you can walk for five miles and not gain six feet of elevation.  Tens of thousands of square miles of South Carolina swamps were converted to rice fields in the 1700s and 1800s but as that crop ended in the early 20th century the rice fields were either developed or left to return to natural vegetation - very similar to New Hampshire's sheep pastures that have returned to forest.
Irrigation canals built to flood and drain the rice fields can still be found.

 It's hard to imagine when touring the cities and suburbs around Charleston or any other Lowcountry city that the land was previously wild swamp with towering cedar and tupelo trees.

Because this land was forested these trees are less than 150 years old, so not nearly as large as the  virgin bottomland forest found at Congaree National Park.

We saw quite a few local birds, some that we don't have in in New England, some that we do.

Those birds were all in the swamps at the Caw Caw Interpretive Center in Ravenel, South Carolina, but this next one is an ocean bird.

We were also treated to an unexpected sight - we got to see a green anole change its color.  We first saw it climbing on the trunk of a tree, wearing its bright green jacket in honor of the Masters golf tournament.

But when it scooted down to the ground and onto the dead leaves it almost immediately changed its color to a dark brown.

I was amazed at how quickly it could completely transform itself, and I assumed it changed color to blend in.  But a little reading revealed that these reptiles do not change color to blend in to their surroundings as commonly believed (which makes sense since on the brown tree trunk it was bright green.)  Scientists are not sure, but current research suggests they change their color based on stress, mood, or for social reasons - e.g. aggression and territory defense.  Did I stress this little guy out by taking its picture without asking permission?

On a different note, the post a few weeks back about a spalted hemlock tree brought to light another wood working artisan with a connection to Lake Wicwas.  A member of one of our Wicwas families collects spalted wood (as well as other types of wood) and turns them into beautiful works of art.  He sent a few pictures of his creations, including this bowl made from spalted maple.

If the tree I found near Lake Wicwas has any useful properties I will be sure to get a section of it to him as well.  Thank you for sharing!

I wonder if there is any spalted wood down in the Lowcountry.

April 14, 2019: The Caravan has Arrived

The first wave of migrants has hit New Hampshire.  The initial sign was the geese, but this week many others started to arrive in droves.  The unmistakable call of the phoebee from the tops of the trees was heard first, and that was soon followed by flocks of dark-eyed Juncos travelling back to the north county.

I find it's one of the hardest birds to photograph, especially on a dreary day

It was unusual for me not to see any of these little "snow birds" around this winter;  they must have traveled to other climes which had better food sources for them.  The first flock arrived on a cold snowy morning, followed shortly by mixed flocks of sparrows and finches making their appearance.

Even without the bird feeders in place and after raking as much of the seed from the ground as possible these specialist in small seeds found plenty to keep them busy.

The nuthatches are far too demanding of their large seeds and nuts to bother with little millet seeds down on the ground.  And it was sad to see the wood peckers come by looking for their usual feeding stations, circling around trees and posts wondering what happened to the easy pickings.  One of the less common birds I see, the common redpoll (an oxymoron there?) was in the flock.

A distinguishing feature of the redpoll is its black face

Just because I don't see them often doesn't mean they aren't numerous.  Estimates of the redpoll population is in the tens of millions, all located in the far northern latitudes.  Though not a finch, they are in the same family as finches and share many of the same characteristics including the preference for tiny seeds as fits their small beak.  Studies have shown that during the winter their diet consists of almost entirely birch seeds.  [REF:  Cornell Lab of Ornithology]

Other members of the flock include the very common Song Sparrow, which in a few weeks will be serenading us with its melodious song on warm spring mornings.

We did suffer a set back on those elusive summer mornings this week when a coastal storm brought in some cold weather and an inch or two of wet, soggy snow.
April showers, New England style

But it won't last long, and we're already back to opening up larger bits of lake to attract more migrants to our lake, including, soon, we hope, our loons!
More open water will attract beavers and ducks soon, and the loons won't be far behind.

April 7, 2019: Otters and Fox Still Trust the Ice

The gaps in the ice at the shoreline have grown into long skinny channels along the edge of Lake Wicwas.  It's now too soft to get out onto the lake;  the last time I was able to go out for a measurement was on April 3rd, at which point there was still 20" of ice, though the top four inches was soft and porous.  Under that was 6" of pretty good white ice, followed by a ten inch layer of hard solid black ice, so it's going to be a while before we see ice out.  I took a run up to the Hamlin Conservation Area trailhead to see the condition of the trails, and there is still a serious layer of ice and snow there.

Be sure to bring some kind of traction devices if you go for a walk - which you should do.  It's beautiful, peaceful and quiet, and on a warm day when the snow is soft, a good time to look for animal tracks.  Speaking of animals, I saw my first red squirrel in many weeks;  perhaps they finally had to vacate the safety of the subnivean world.

The treacherous ice hasn't stopped the animals from taking shortcuts across the lake.  Just yesterday morning I saw a healthy looking red fox trotting calmly across the lake, coming right towards me.

It would be interesting if he came across that flock of turkeys on the ice.  Of course, this could be Mrs. Fox who at this point would be either very pregnant or out in search of food for her brood of perhaps six kits.  Either way, the nice thick winter coat makes me think this fox found plenty to eat this winter.  You can find a nice write up about red fox (and some great photographs) by Charles H. Willey  published in the NH Fish & Game "Wildlife Journal" on their website here.

Earlier in the week Linda's sharp eye caught a large animal bounding far out on the lake from one shore to the other.

I had just enough time to click a fast shot before it zoomed in behind the tree line, and blowing it up, we could see it was an otter.

I've seen otter tracks on that line several times this spring but that's the first time I (or Linda rather) saw one in action.  But out in the middle of the lake, he wasn't playing around, he was on a mission to get back under cover.  Would a bald eagle go after something that large?  It wouldn't surprise me.  He might have been travelling back from a fishing trip at the outlet of Lake Wicwas which for the first time this year has started to open up.
Open water starting to appear

On the other side of the dam the stream leading to Lake Winnisquam is swollen with water backed up by beaver dams between the two lakes.

One of the surest signs of the progressing season is the sun setting farther to the north and bright summer-like sunsets glowing across the northern stretch of the lake.

Another early spring sighting:  The first pussy willow.

All of this means it's time to bring in the bear, ooops, I mean bird feeders.  Bears will be out soon, though I haven't seen any signs of them yet.  Let me know when you see or hear of their appearance from their winter slumbers.  Certainly the pileated woodpeckers are out and finding insects to dine on.

This week the Meredith Historical Society started their monthly presentations.  The first presenter was Kevin Gardner who gave a great talk on the construction, history, and significance of New England's quarter-million miles of hand-layed stone walls.  He pointed out that's enough stone wall to reach from the Lakes Region to the moon.  That's a lot of effort put in by our early settlers, and he explained why they did all that back-breaking work.  While he was talking he built a stone wall for us, right there in the room.

These presentations take place the first Tuesday of each month at the Meredith Community Center.  You can find the schedule of presentations here.  By the time the next one occurs, we should for sure be into summer sunset season!
