September 14, 2025: Spider Webs in the Morning Dew

We had a series of cool nights this week with each night falling well into the 40s.  One cool morning, with everything drenched in condensed water, I found an extraordinary array of spider webs adorned by the dew that formed overnight.  These webs are probably there every morning, they just aren't so visible.  I enjoyed examining the different form and structure and site of each spider's web.  The variety of approaches each species takes to catch food is its own lesson in evolution.  First off, the classic spiderweb of an orb weaver:

The well-planned geometric web of an orb weaver.

This orb weaver built its nest in a small tree at the edge of a field filled with much different spider webs.

A recently mowed field full of spider webs.

These were nothing like the carefully planned and constructed web of the orb weaver, but rather a seemingly random, dense network of threads designed to capture the smallest of insects in the grass.

Thick webs built low down in grass.

This one has a tall spire attached.

Does the tall web perform a particular function in relation to the thick web below?  

This next similar web was also in the grassy field, but built on a tall flower stalk, giving it yet different properties.

This could be the same species with a different idea on how to catch breakfast, or a completely different species.

In yet another location, deep in a mature forest, were more dense webs, but these were built high up in tree branches.

Spider silk is made primarily of protein, and spiders create unique types of silk for different uses with each type formed by a different gland in their body.  The strong silk that forms the frame of a web is called dragline silk.  This silk, which isn't sticky so the spider can walk on it, is stronger by weight than nylon and even Kevlar.  [REF:  Römer L, Scheibel T. The elaborate structure of spider silk: structure and function of a natural high performance fiber. ]  A spider fills in the web structure with a sticky silk called capture silk.  There are yet other silks that are used for preserving captured prey, wrapping eggs, and even a light silk used as a balloon to travel long distances on the wind.  

The spider's ability to create such useful material made me think that we humans have evolved with the ability to create incredible things with our brains and hands, but there's really nothing useful we create using just our bodies like a spider does.  There's a whole world of science that studies spiders and their silk.  See the above reference for a glimpse into that world.

The colder nights makes me think about how the next couple of months are critical times for animals bulking up on food stores, either to get through winter hibernation or for a long migration to the south; for some animals this continues through November.  As noted last week, many food sources are ripening now, just in time for this feeding frenzy, including berries, mushrooms, and seeds from plants large (oak and beech trees) and small (milkweed and asters).  Hobblebush viburnum are highly visible with their red and black berries growing in large clumps on chest-high shrubs.

Old neglected apple trees are ripening their fruit for animals like deer, bear, fox and coyote, all of which will eat them right from the tree or after they've fallen on the ground.  Black cherry trees likewise are maturing their fruit as our young robin from last week knows.

Black Cherry

Black cherries are mostly pit with little flesh; the flesh is edible by humans, though the pits, which produce a cyanogenic glycoside, are not. [REF: https://plants.usda.gov/DocumentLibrary/plantguide/pdf/pg_prse2.pdf]  Birds consume the flesh but not the seeds, which they distribute widely after they pass through their digestive systems.  Rodents on the other hand will eat the flesh, but they also can crack open the pits to eat, or store the pits in their winter caches.  Bears and foxes are like the birds in that they eat cherries only for the flesh, and then plant the pits wherever they leave their scat.  

Other fall berries I seen now are Winterberry, False Solomon's Seal, and Bunchberry.

False Soloman's Seal

Bunchberry

I'm told the Summer mechanic team at a particular ski area has their own name for bunchberries: "Oh Shoot berries" (or something similar to that ;-)  The name derives from the fact that when these berries turn red, it means, oh shoot, we only have a couple of weeks left to finish all our summer maintenance before the snow flies!

I've seen a few garter snakes around lately.  In preparation of their winter hibernation, they're probably feasting on the many small frogs that have been hopping all over the place this summer. 

Common Garter Snake

It's amazing how large a frog a small snake can swallow whole.

We were in mid-coast Maine for most of this week so I wasn't able to check on the loons.  I spent a lot of time along marshes and estuaries where I saw the usual shorebirds including pipers, plovers, eagles, and osprey, but only one new bird, a Killdeer.  I first heard it at night as they were calling while hunting beneath a bright full moon illuminating the estuary all week.  It was unusual to hear something other than loons or owls at night.  For those who love Maine as much as we do, here are a few familiar sights from the Wiscasset Area.

June 8, 2025: Great Crested Flycatcher

The dragon flies came out in full force with the warm temperatures this week which means it's feast time for the birds - no more need to go after tiny mosquitoes and black flies when there's much larger game available.  I mentioned recently the distinctive call of the Great Crested Flycatcher and on a paddle this week there was one calling loudly near me which I was able to locate perched on its branch waiting to attack whatever flew by its outpost.

Great Crested Flycatcher

In addition to the Phoebes which have been here for weeks, the Eastern Kingbirds now have a large presence around water as well.

Eastern Kingbird

All three of these flycatchers are quite noisy birds.  I also saw a couple of Belted Kingfishers this week.  

On the loon front, it appears the southern pair has decided to build a nest on a tiny hummock deep in Harris Cove.  It's well protected from boat traffic but won't have any protection from the sun which could be a problem for them.  At last check they weren't on the nest, so there probably wasn't an egg yet, but by today there might be.  If all goes well, mark your calendar for a chick just after the fourth of July.

One morning this week a pair of float planes landed on Wicwas.  

The two are the same model of pusher-plane with different paints schemes.

Note they have wheels as well as floats for water.

The loons were not pleased with these large noisy birds flying over them.

There are so many birds in the trees now feeding happily on flying insects as well as the crawling ones:  caterpillars.  One native caterpillar that has developed an excellent defense mechanism is the Tent Caterpillar.  

Tent caterpillars create a defense shield against predators.

Tent caterpillar are not a species at risk and since they can defoliate small trees there's generally no harm in removing them if you wish.

The bunchberry is booming now; I saw these up by Arbutus Hill Pond in the Hamlin-Eames property behind Lake Wicwas.

More white flowers are adorning the False Soloman's Seal plants.

Later in the summer these will have large bunches of red and white speckled berries which are consumer by birds and rodents.  The Canada Mayflowers didn't quite live up their name this year, but they only missed it by a few days as they are blooming now in early June.

And thank you Canada for giving us some gorgeous red sunsets this week.

That's about the only good that comes from those wildfires, but we might as well appreciate whatever we can!

September 17, 2023: Nature's Hovercraft

Most of nature's flying creatures have evolved with a bias towards fast, efficient flight, but there are a few animals which in addition to being very quick and maneuverable, have the ability to hover in place like a helicopter.  Hummingbirds achieve this feat through unusual shoulders that give their wings a large range of rotation rather than a simple up and down motion with limited rotation.  

A hummingbird rotates its wings in a figure-eight pattern, which provides lift on both the forward and backward wing stroke, a most valuable ability when drinking nectar from a flower who's stalk won't support even the one-tenth of an ounce weight of a ruby-throated hummingbird.  

The dragonfly is even more advanced in its flight surfaces.  Dragonflies have four wings, each of which can move independently of the others.  This gives it the ability to fly forward, backward, up and down, even sideways - important features when hunting down other agile flying insects on the wing.  Though dragonflies have the ability to hover, and use it regularly, they don't hover in one place for long.  I watched a group of them hunting over a marsh this week, devouring insects, and though they would hover for a moment, by the time I pointed the camera, they had zoomed away.  And it's not easy focusing on a small, fast moving object.  I took dozens of pictures to get one decent shot that shows all four wings.

On this same paddle I saw a bird that uses a different technique to remain stationary while hunting for food.

This osprey was perched in a tree often used by an eagle, which is what I thought it was from a distance.  Osprey migrate south starting in September, so maybe they'll head off with the strong northwest winds from hurricane Lee, but they've been very visible and audible the past few weeks.  I've heard them crash into the lake when they've targeted a fish from their high perch, then fly up and away with dinner in its talons.  If you want to see a fantastic video of an osprey diving for a fish, watch this video from Mark Smith Photography.  (I think it's better with the sound turned off.)  Osprey are the only birds I'm aware of that dive well under water to catch their prey.

In June (June 11, "Fern Weather") I noted a Jack-in-the-Pulpit growing along the side of the road.  Now, three months later, the Jack-in-the-Pulpit are showing the world their snappy red berries.  

Jack-in-the-Pulpit (Arisaema triphyllum)

Birds consume these berries, including turkey and wood thrush.  

Another plant sporting red berries now is the False Soloman's Seal, which was also mentioned in the same June post - they must have the same game plan.

False Soloman's Seal (Maianthemum racemosum)

These not quite as showy berries are food for mice as well as many birds, including grouse.

LuLu and Checkers are really getting independent.  We sometimes see them with no adults anywhere in sight.  It makes me wonder if the parents occasionally head off to force the juveniles to learn to fend for themselves, as well as to get some peace and quiet - the kids constantly whine at them for food when they're together.  One afternoon I took a picture of a parent and a kid, only to find out later I was photobombed once again.

The heron posed a few days later for a private sitting, for which which Linda did the honors.

The fall wildflowers continue to shine.  Asters now call our attention in walks through fields and along roadsides.

Hurricane Lee was kind to New Hampshire, staying well offshore and sending us only a moderate northwest wind with a bit of rain.  The night before it went by, Lee even gave us a brilliant sunset.

Fall officially arrives next Saturday.

June 11, 2023: Fern Weather

A stretch of cool, damp weather is just what ferns and other wetland-dwelling plants love, so they were in their element this week.

Cinnamon Fern (Osmundastrum cinnamomeum)

The cinnamon fern is identifiable by its distinctive cinnamon-colored central fronds that grow straight up, surrounded by large green fronds, both of which can grow up to five feet high in fertile wetlands.  When these ferns emerge in spring as fiddleheads they resemble the edible ostrich fern, but cinnamon fiddleheads have a white, fuzzy covering over them.

Don't eat fiddleheads that have this white, fuzzy covering.

In comparison, ostrich ferns have a thin, brown, papery covering.  Even the edible ostrich fern can contain toxins, but not enough to cause problems.  The cinnamon fern has sufficient toxins that if eaten can cause nausea and other symptoms.  

The Jack-in-the-Pulpit is often found in cultivated gardens, but it also grows wild in the Lakes Region.  I found this one at the edge of a drainage ditch along a dirt road.  It took me a minute to figure out why it didn't look quite right:  its leaves had been chomped off by a deer.

Note the bare stalks where the leaves have been eaten off the top.

Another plant that favors cool and damp is the false Soloman's seal.

Later in the summer the pretty white flowers will produce deep-red berries which are edible, but with a large pit and little flesh, they're not worth much more than a sample of one or two as you pass them by.

One more spring flower blooming now is the bluebead lily.

These will have large, blue berries in mid-summer, but they are not edible.

Thanks to Amy Wilson's good eye, we finally confirmed that the female of the loon pair that nests in Harris Cove has returned.  Reports are that the pair continues to poke around the islands looking for a safe place to build a nest but still hasn't settled on a site.  The Loon Preservation Committee biologist visited Wicwas again this week and confirmed that all is well on the northern nest.  

One of the Harris Cove loons caught itself a really nice meal one morning.

A fish this size might be a whole meal.

It had to spend several minutes beating it up enough to dare to swallow it.

A loon doesn't want a fish this large flailing around in its gullet.

It looks to me like the fish was a black crappie.

That's a favorite pan fish for humans too!
