songs in the grey woods – northern parula
A friend, a knowledgeable wetland biologist, has been helping me learn some new bird songs. Last week, I identified the song of the Northern Parula. This is a bird I have never seen, though I scan those tree tops with the binoculars until my arms ache. I have heard its song so many times and always wondered what it was. The song is a long whirrrrr, flowed by a short, upward flip. Whirrrr -flip. Whirrrr- flip. This morning it was the first song of the morning bird chorus!

It drives me crazy to hear him sing, be able to find the tree he is perched in, but not see him. My painting is how I think he must look, based on descriptions on the net.
The Parula is a blue-grey bird with a yellow throat, and a yellow and white breast. He has a white crescent above and below his eye and two white wing bars. A bright and beautiful bird! He has an association with a lichen I love, Usnea subfloridana, Old Man’s Beard. He uses the lichen to build his hanging nest.

a moment of beautiful – sun on icy drops of rain
~
After the rain overnight and some icy temperatures, the melting ice on the Old Man’s Beard lichen and the ice coat clinging to the branches made for a beautiful scene outside my guest room window. To add to the show, a stray reflection of sun projected dazzles of light on the garage doors.

harvesting colour – beautiful brown!
I will never see brown with the same eyes again!
~
Today I finished a batch of alum-treated raw wool and I was ready to try my first experiment with dyeing animal fibre. The alum, you will remember, is a mordant, added to the fibre to increase its colour-fast and light-fast qualities. In some cases, it also makes the colours brighter.

Remember my gathering of Old Man’s Beard lichen? (https://nichepoetryandprose.wordpress.com/2014/03/26/colour-on-the-snow/)

The lichen has been ‘fermenting’ in ammonia about a week and developed a lovely brown colour with tones of orange, reminiscent of root beer.

I sieved out the lichen and added the dye to my dye pot. I added a little vinegar to neutralize the alkalinity since basic solutions can harm the wool. I put about one once of the alum-treated wool into the dye pot and added water, to cover the wool. Then I increased the temperature very, very slowly since sudden changes in temperature can damage the texture and weaken the fibres. I left the dye pot on simmer for about an hour and then left it to cool slowly. Now the wool is drying on the line in my dining room.
~
The result may seem like an unimpressive brown, but to me it is the most wonderful brown in the world. Reminds me of the ice cream in a root beer float! My first effort at dyeing wool, and obtained from a lichen of the palest green. I feel a poem stirring!

air to breathe
As I approach retirement, I find I am thinking a lot about my past work. My first job was as a botanist in the field of air quality.
Some plants are very sensitive to air pollutants and develop ‘herring bone’ patterns on the leaves when the levels of pollutants like sulphur dioxide get too high. Other plants can be used as monitors since they absorb pollutants from the air.
I worked to diagnose air pollution injury to sensitive plants and designed ways of using plants to assess air quality problems. We grew tobacco to measure ozone pollution, set out ‘tea bags’ of sphagnum moss to monitor levels of trace metals in the air, and collected reindeer lichens to determine their pollutant exposure. I had wonderful days identifying plants, collecting lichens and being a botanist.
My favourite air pollution monitors were the reindeer lichens. These are like all lichens, a symbiotic organism consisting of an algae and a fungus. They have no roots, so they absorb all their nutrients from the air, making them an excellent monitoring system for air pollutants. They were a challenge to identify and the habitats where they grew took me to some very interesting places in New Brunswick. These included peat bogs where the lichens grew beside pitcher plants and sundews, mountain-tops dominated by ericaceous species like sheep laurel (Kalmia angustifolia L.) and blueberry, and high flung rock outcrops where I could see all the world below me as I picked my specimens.
Although we collected many species, the three reindeer lichens most useful for our studies were Cladina arbuscula, Cladina rangiferina, and Cladina stellaris. These are all ‘fruticose’ lichens, species with a ‘shrubby’ appearance, consisting of a main branch with many side-branches. A single ‘plant’ fits nicely in your hand. The Cladinas all have hollow branches and could be (and are) used as little trees in HO scale train models.
- Cladina arbuscula (left) and Cladina rangiferina (right) growing on a rock by the roadside in Maine. You can tell the difference by the greenish color of the arbuscula and the bluish-grey color of the rangiferina.
Cladina arbuscula (Wallr.) Hale & Culb. grows in extensive colonies, and is yellowish-green. The tips of the branches all point in one direction, a distinguishing characteristic of the species. Cladina rangiferina (L.) Harm. is often found growing with Cladina arbuscula and can be distinguished from arbuscula by its very blue-grey appearance.
Cladina stellaris (Opiz) Brodo is yellowish-grey, and grows in distinct clumps which resemble small ‘poofy’ trees.

On our travels this summer, I reacquainted myself with the Cladinas. And I remembered all the remote places I have been as a result of my work. One of these was Turtle Mountain in southern New Brunswick, now protected as part of the Loch Alva Protected Natural Area (PNA). It is a very old mountain, worn to a granite hill. At the top of the hill, is an ericaceous meadow where Cladina lichens flourish.

a place to wait, out of the rain
My husband and I love to go for drives in the countryside, and we often turn these trips into ‘expeditions for collection’. For example, in 1992, we began a project to see all the covered bridges in the province; of the more than 60 covered bridges in New Brunswick, we have ‘collected’ about three-quarters. Recently, we began a quest to see as many waterfalls as possible (the state of my arthritic knees puts the emphasis on the ‘as possible’).
This spring, we set out with a very reasonable goal, to see the three lychgates at Anglican churches in the Diocese of Fredericton (all of the Parishes in New Brunswick are located in the one Diocese). This idea came from a short article in the New Brunswick Anglican in 1997 by Frank Morehouse (‘Only three lych gates remain in the diocese’). The three lychgates are at St. Anne’s Chapel in Fredericton, St. James Church in Ludlow, and St. Paul’s Church in Hampton.
Lychgates are an architectural remnant of past practice, dating back to the 13th century. They were used as a part of the funeral service, a place for the priest to meet the body of the deceased on its way to burial, and a shelter for the pall bearers to stand out of the rain. The word lychgate comes from the Anglo-Saxon word lych meaning corpse.
A typical lychgate is made of wood, and consists of a roof supported by a framework of two or more posts, and a gate hung from the framework. Lychgates usually stand at the entrance to the church property or the graveyard. They can be architecturally ornate.
Today the lychgate is a picturesque feature of the churchyard, but they also create habitat for wild life. Spiders tuck their webs in the rafters of the structure where they are safe from wind and rain. The shingled roof of a lychgate is often a place where lichens and mosses can grow without competition from other plants.
Our collection of lychgates at Anglican churches in New Brunswick is complete. We found the lychgate in Fredericton on a rainy day in April…

‘niche’ on a rock
In July, we went to the Saint Martins area for the day and spent some time exploring the caves and beach-combing. We also took the short drive to the lighthouse at Quaco Head. The lighthouse is perched on the cliff overlooking Quaco Bay.
the Quaco Head Lighthouse ....... “The present Quaco Head Lighthouse was constructed in 1966 and consists of a square tower rising from one corner of a concrete fog signal building. The light in its lantern room produces a white flash every ten seconds, while the fog signal emits a three-second blast every thirty seconds, when needed.” from http://www.lighthousefriends.com/
If you look out over the Bay, you can see some exposed rocks where sea birds make their home, and, to the north-east, Martin Head, about 30 kilometers away.
the view to the north-east ...... Martin Head is on the horizon, to the left
Wildflowers were everywhere, but what caught my eye was a lichen on a flat rock at the base of the lighthouse. It was bright orange, like a splash of paint.
There are two orange lichens that live on rocks in the coastal area of New Brunswick, Xanthoria and Caloplaca. The orange lichen I found at Quaco Head is likely one of two species: Xanthoria sorediata (Vain.) Poelt or Xanthoria elegans (Link) Th. Fr.

A lichen is not a plant, but a composite organism, consisting of an algae and a fungus, living together in a symbiotic, mutually beneficial, relationship.

‘niche’ above the ground
Around us are spaces so familiar, we don’t pay attention to them anymore. I remember this when I walk in the woods near our house. On the ground, at my feet, are layers of leaves from last autumn, the carpet of mosses, the plants of the understory.
And then I remember to look up and see the space above me.
This space is the realm of the trees. It is a space shaped by their canopies, the needles of the Balsam Fir and White Pine, the leaves of Red Maple, and the dead branches and twigs of the spruce. Most of the trees reach upward, roughly perpendicular to the ground. They stand together, parallel, the masts and rigging of a sailing ship. Others have succumbed to decay and gravity and wind, and have fallen. Their trunks make diagonal slashes through the spaces above and leave gaps in the canopy.
snowshoe trail and sap bucket on maple
These are spaces I cannot access, since my tree-climbing days are over. But I can move there, briefly, in winter. When the snow builds on the ground, it lifts me into the trees. I am reminded of this when I see the empty tap holes in the trunks of the maples along the trail. These are the holes left behind when we pull the taps at the end of maple syrup production in the spring. When we collected the sap, the taps were about three feet above the surface of the snow, so we could access them easily. Now, snow gone, the tap holes are above my head. Our snowshoe paths were elevated into the space above the ground. One winter the snows were so high, we had to trim the branches along the trail. Next summer we could look up and see our winter path, traced by the absence of branches in the space above our heads.
Usnea subfloridana Stirt. is a lichen often found growing on old and stressed trees in coniferous woods. The common name, Old Man's Beard, refers to the matted, stringy appearance of the lichen, hanging in clumps from tree branches. Lichens are made up of two species, an algae and a fungus, living together symbiotically.
