1-beaver-brook

It has cooled off now but “cool” compared to the near 70 degrees of last week means 40s and 50s this week, and that’s still warm for March first. That means a lot of snow has melted and that has turned our normally placid streams into raging rapids, as this shot of Beaver brook shows. No beaver in its right mind would be swimming in that.

2-beaver-tree

But they do eat trees all winter long if the ice of their pond doesn’t freeze completely. This beech tree was still being visited each night well into February. The hole in the ice must have closed up because they haven’t been here for a while.

3-beaver-tree

A beaver’s teeth grow continuously so they have to be chewing on something all the time. In this instance a beech tree was chosen, but they’ll chew on just about any species of tree. I’ve even seen them tackle  elms, which is one of the toughest woods I know of. Their incisor teeth wear away faster on the rear surface than the front, so a chisel edge is created by the uneven wear.

4-beaver-tree

The chisel edged teeth of a beaver can leave a sapling looking like it has been cut by steel loppers. Native Americans called beavers “Little People,” and are said to have greatly respected them. They used beavers for food, medicine and clothing and Native children of some tribes would offer any teeth that they had lost to the beavers for good luck.

5-rose-moss

I decided to pay a visit to the one small patch of rose moss (Rhodobryum roseum) that I know of. Rose moss is a very beautiful moss; each little rosette of leaves looks like a tiny flower, and that’s how it comes by its common name. Rose moss is a good indicator of limestone in the soil so it’s wise to look for other lime loving plants in the area when it is found. This is a relatively rare moss in my experience.

6-smoky-eye-boulder-lichen

Not rare at all but still very beautiful are the smoky eye boulder lichens (Porpidia albocaerulescens) that I find growing on stone. The golden body of the lichen studded with blue apothecia could almost pass for a piece of jewelry. The blue color is caused by the way light reflects off a waxy coating on the fruiting bodies (Apothecia,) which is very similar to the “bloom” found on plums, blueberries, and grapes. It’s as if pieces of the sky had been sprinkled on the stones when the light is right, but the apothecia can also appear black or gray depending on which direction the light happens to be coming from.

7-spider

One morning as I was getting ready for work I saw something move out of the corner of my eye. It was a tiny spider with big eyes. It sat very still, watching me as I fumbled with my camera, trying to turn on the on board LED light. I finally got it and that’s what caused the shadows in this photo.

8-spider

It was a furry little thing. And it was little; it could have easily hidden behind a pea. It wasn’t frightened by the camera and remained still, seemingly very interested in what I was doing. It had plenty of eyes to watch me with. (They have 8 of them.)

9-platycryptus-undatus-female-tan-jumping-spider

I got a blurry photo of its back as it scurried away, and the markings lead me to believe that this was a female tan jumping spider called Platycryptus undatus. I’ve read that they live on vertical surfaces like tree trunks, fence posts, and outer walls so what she was doing on my horizontal table is a mystery. I’ve also read that they are very curious about people and can be quite friendly when they’re handled gently. I didn’t see this one jump but they do, up to 5 times their own body length. Which isn’t far when you consider that this one was half the size of a pea. I haven’t seen her since that morning.

10-bittersweet-berry-2

There are still quite a few oriental bittersweet berries that the birds haven’t eaten and that’s a good thing, because birds help this very invasive alien plant get around. This example didn’t look very tasty.

11-bittersweet-on-tree

Oriental bittersweet isn’t well liked by those who know it, and the above photo shows one reason why. The vines are as strong as wire and when one wraps itself around a tree it will not break or give, so as the tree grows the vine cuts into it and strangles it. The tendrils on the left are from another vine; a grape.

12-oak-leaf-surface

A stick figure walked across an oak leaf.

13-winter-firefly

I’ve never seen a firefly light up in winter but I have seen the winter dark firefly (Ellychnia corrusca.) It is commonly seen on snow and tree trunks  according to Bugguide.net, and can be a pest in sap buckets in the spring because they like sap and will drink from wounds in trees. They like to sun themselves on the sunny side of trees or buildings, but this one was looking for a crevice in the bark of an oak to hide in. It looked at several before it found one that was to its liking.

14-gypsy-moth-egg-case

I saw this gypsy moth (Lymantria dispar) egg case on a tree. Gypsy moths were first introduced from Europe to Massachusetts in 1869, to breed with the silkworm moth to produce a tougher silkworm. Naturally, it escaped and has become one of the chief defoliators of deciduous trees and conifers in the eastern United States. Each egg mass can contain 100-1000 eggs and should be destroyed when found. It looked like a bird had been at this egg case.

15-beard-lichens

I see beard lichens (Usnea) almost always growing on tree branches but occasionally they grow on tree trunks; especially white pines (Pinus strobus.) Even rarer are those that grow on stone. I see maybe 1 out of 100 growing on stone. If you see beard lichens in your area rejoice, because they are very fussy about pollutants and will only grow where the air is clean and of high quality. The air here must be very good because I see these bushy little lichens everywhere, even growing on wooden fences. Lichens in the Usnea genus contain usnic acid and have antiseptic / antibiotic properties. They have been used since ancient times throughout the world to heal wounds.

16-unknown-lichen

I’ve spent years trying to identify some lichens and I might have to wait that long before I know this one’s name. I’ve searched lichen books and online and can’t find any lichens that look like it. Blue and yellow doesn’t seem to be a very common color combination among lichens. This example grew on maple tree bark.

17-mealy-rim-lichen

The book Lichens of North America says the fruiting bodies (apothecia) of the mealy rim-lichen (Lecanora strobilina) are flat to convex and a waxy yellowish color. These look more orange but I’m sure they must vary some. They grow on bark and wood of many kinds in full sunlight and the apothecia are very small at about .03 inches.  I think this is one of those lichens that prefers winter for producing spores. I’m suddenly seeing it everywhere.

18-disc-lichen

I know disc lichens because of rock disc lichens (Buellia geophila) but the problem was the example in the above phot was growing on tree bark. For that reason I think it must be a cousin of the rock disc called simply disc lichen (Buellia erubescens.) The body of the disc lichen is gray, grayish white to ivory, dull, and smooth. Its fruiting bodies are convex and black, and are called discs. It grows on the bark of oaks, pines, and junipers, or other trees with bark of low pH. I found this example growing on an oak.

19-feather

This is just a small feather in the mud but it was pristine and very downy, like it came from a bird’s breast.  It’s a beautiful thing.

Leisure is a form of silence, not noiselessness. It is the silence of contemplation such as occurs when we let our minds rest on a rosebud, a child at play, a Divine mystery, or a waterfall. ~Fulton J. Sheen

Thanks for stopping in.

1-snowy-road

This is the road I drove down early one morning after a 5 inch snowfall the night before. The pre-dawn light was really too dim to take photos, but I didn’t let that stop me. It was too pretty, I thought, to pass by without recording it. As Scottish author William Sharp noted: “It is the still ecstasy of nature, wherein every spray, every blade of grass, every spire of reed, every intricacy of twig, is clad with radiance.”

2-winter-brook

A small brook wound its way through the woods. I loved its polished black surface against the snow.

3-beech-leaves

Beech leaves provided a touch of color.

4-monadnock

Mount Monadnock loomed dramatically over the surrounding countryside in a view of it that I’ve never shown here before. In another half hour when the sun kissed its flanks it would probably have made an amazingly beautiful scene but I was on my way to work and I didn’t have time to dilly dally. There was snow to move.

5-ice-shelf

Ice shelves have begun forming along the Ashuelot River. This one was clearly visible as a shelf but when they’re completely attached to the river bank and are covered by snow they can create a very dangerous situation, because there are times when you can’t tell if you’re walking on land or on an ice shelf. I’ve caught myself standing on them before and that’s why I now stay well away from rivers in winter unless I know the shoreline well.

6-snow-melt

The dark trunks of trees absorb heat from the sun and reflect it back at the snow, which melts in a ring around it. These melted rings seem to be a magnet for smaller birds and animals like chipmunks and squirrels.

7-black-eye-lichen-tephromela-atra

If I see whitish or grayish spots on tree bark I always like to take a look because it could be a script lichen or some other lichen that I’ve never seen. In this case it was what I think is a black-eye lichen (Tephromela atra.) According to the book Lichens of North America this lichen grows on stone, bark or wood from the tropics to the arctic.

8-black-eye-lichen-tephromela-atra-close

As you can imagine the raised rimmed, black spore bearing apothecia of the black eyed lichen are extremely small, so it’s always a good idea to carry a loupe or a camera with macro capabilities. Many features on this and many other lichens are simply too small to be seen with the eyes alone.

9-mealy-rim-lichen-lecanora-strobilina

Another small lichen on a different tree showed some unusual color in its apothecia but I couldn’t see any definite shape without the camera.

10-mealy-rim-lichen-lecanora-strobilina-close

The book Lichens of North America says the apothecia on the mealy rim-lichen (Lecanora strobilina) are flat to convex and a waxy yellowish color. They grow on bark and wood of many kinds in full sunlight and the apothecia are very small at about .03 inches. Though the color here looks more orangey pink I think the light might have had something to do with that.

11-pixie-cup-lichens

Pixie cup lichens (Cladonia pyxidata) look like tiny golf tees or trumpets, and they are also called trumpet lichens. They are common and I almost always find them growing on the sides of rotting tree stumps. Pixie cups are squamulose lichens, which means they are scaly, but they are also foliose, or leafy. A squamule is a lobe of the body of the lichen (Thallus,) and squamulose lichens are made up of small, leafy lobes. As can be seen in the center of this photo the stalk like cups (podetia) grow out of the leaf like squamules. This is the first time I’ve ever caught it happening in a photo. Pixie Cups were used by certain Eskimo tribes as wicks in their whale blubber lamps. The lichens would be floated in the oil and then lit. The oil would burn off of the lichen but the flame wouldn’t harm it.

12-red-maple-buds

Red maple flower buds (Acer rubrum) are just waiting for the signal from spring. These are one of my favorite early spring flowers and I’m looking forward to seeing them again. The flowers, twigs, leaf stems, seeds, and autumn foliage of this tree all come in varying shades of red. These buds are tomato red, according to my color finding software.

13-hawthorn-bud

Hawthorn buds (Crataegus) are also tomato red but they’re very small; each one no bigger than a single flower bud in the clusters of red maple buds in the previous photo. I had to try several times to get a photo of this one. I think an overcast day might have made things easier. There are over 220 species of hawthorn in North America, with at least one variety native to every state and Canadian province. In New Hampshire we have 17 species, so the chances of my identifying this example are slim to none. Since I see it regularly I know that it has white blossoms.

14-hawthorn-thorn

The hawthorn also has red thorns; as red as its buds and sharp as a pin. This one was about 2 inches long. Hawthorn berries and bark were used medicinally by Native Americans to treat poor blood circulation and other ailments.

15-box-buds

I was surprised to see the flower buds of this boxwood shrub (Buxus) showing color on one recent warm day. I hope it was telling me we’ll have an early spring! Boxwood is called “man’s oldest garden ornamental.” The early settlers must have thought very highly of it because they brought it over in the mid-1600s. The first plants to land on these shores were brought from Amsterdam and were planted in about 1653 on Long Island in New York. There are about 90 species of boxwood and many make excellent hedges.

16-winter-fungi

Jelly creps (Crepidotus mollis) are small, quarter sized “winter mushrooms” that like to grow on hardwood logs. They are also called soft slipper mushrooms and feel kind of spongy and flabby, much like your ear lobe. They grow with an overlapping shelving habit like that seen in the photo.

17-bee-balm-seedhead

The flowers of native scarlet bee balm (Monarda didyma) are tubular and grow out of leafy bracts, and these bracts were all that was left of this bee balm plant. This is the first time I’ve noticed that they had stripes. The Native American Oswego tribe in New York taught the early settlers how to make tea from bee balm. The settlers used it when highly taxed regular tea became hard to find and it has had the name Oswego tea ever since. The plant was also used by Native Americans as a seasoning for game and as a medicine.
