Red Is For Christmas

Nature's Red Spells Christmas

High-bush Cranberry Viburnum opulus

Christmas is a time for red, to cheer us from a dull landscape.  The human eye likes the colour red.  Perhaps it is because it is the complementary colour to green which we see so much of in our surroundings.  It acts as 'eye candy' and a wonderful accompaniment to Christmas.

Red is not a common colour for wild flowers.  So, we start celebrating in summer with the two shown above, the Red/PurpleTrillium and the Cardinal Flower.  The Red Trillium grows in our mixed and hardwood forests in early spring.  It is a welcome sight after a long winter.  It is sometimes called Wake Robin.  The Cardinal Flower is smallish and insignificant on first sight.  But looking closely it is very beautiful.  What a gorgeous colour!  It grows along stream banks and adjacent damp meadows in a few places here.

Winterberry Ilex verticillata

Shown above are the pleasing red of two of our berries.  These ripen in the fall.  Mountain Holly is found in damp thickets, swamps, bogs and wet woods.  Winterberry is beautiful in late fall and early winter as the bright red berries cling to the naked stems.  It is often picked and placed in Christmas bouquets.  

Florists market many commercial red flowers at Christmas time.  Shown below are the red rose and the amaryllis.

And, to finish this post, I will show a photo I took of a visit to a greenhouse where poinsettias were being grown for Christmas.  What a sight this was!

Mountain Bluebird

Rare Fall Vagrant Found in Acadian Peninsula

Mountain Bluebird 

New Brunswick has had a rare visitor for the last 10 days or so.  A rare fall vagrant has been found in the Acadian Peninsula near Inkerman at Four Roads.  Although the bird may have left yesterday according to a report today, many birders and other interested people have seen it.

The Mountain Bluebird is a member of the Thrush Family and is a 'cousin' to our Eastern Bluebird and our American Robin.  Its preferred habitat is fields and field edges and mountainous areas.  It normally breeds in the Prairie Provinces, British Columbia, the western states and northwards into Alaska and Yukon.  It winters in southern California, Nevada, Arizona, and northern Mexico.  So the bird that was found here should be headed for Arizona now.  It is rare to find this species here but it does happen occasionally.  One was seen in 1996 in Caraquet and one in Pennfield in 2000.

Why is this bird here?  We don't know for sure but it is thought that their navigation system gets damaged somehow so instead of travelling southwest, they travel northeast, for example.  It could have also got caught up in high winds during a weather system which blew it way off course.

Mountain Bluebird

The Mountain Bluebird is about the size of our Eastern Bluebird, 7.25 in. or 18.5 cm long.  The male is very blue over most of its body, darker on its wings.  The blue of this bird is iridescent, a very beautiful colour.  Eye candy indeed!  Our visitor is a female and she is duller with gray on her throat and breast and ultramarine blue on her wings and cerulean blue on her back and tail.  She is still amazingly beautiful.  They are cavity nesters like our bluebirds and readily use nest boxes.  They use tree cavities in the wild.

Mountain Bluebirds feed on insects, fruits and berries.  They are the only bluebird which hovers.  That was what the bird at Four Roads was doing, hovering over the field and dropping down to get an insect.  The one which I saw in Pennfield in 2000 was in a blueberry field eating blueberries.

The Mountain Bluebird flies like our Robin.  It has long primary feathers and the long primary projection is a way to tell it from the Western or Eastern Bluebird when there is a question.  This could happen when sometimes the female shows a bit of orange tinge on its breast causing some confusion.  The primary projection is a technical term used by serious birders and denotes the length the primary feathers project over the tail in a sitting position.

Shown below is one of the many peat harvesting sites from the Acadian Peninsula, near where the Mountain Bluebird was found.  It is good to boost the economy with the sale of natural resources but one wonders how long it will take before these areas return to natural vegetation which can be used by our wildlife.

Birding the Tantramar

Tantramar Marsh Supports Significant Bird Population

Tantramar Marsh

On November 26 we visited the Tantramar Marsh looking for birds and other wildlife.  It was a warm, sunny day and great to be out!  Although we covered all the roads in the marsh we spent more time on the Anderson Marsh Road.  

We were looking mainly for raptors.  The marsh is a good area for them to rest on migration because of suitable habitat and a high rodent population, the main diet of many raptors.  We saw many hawks including 13 Northern Harriers, 4 Rough-legged Hawks, and 2 Red-tailed Hawks.

Eagles were also taking our attention.  There had been a few sightings of a Golden Eagle there in the last two weeks but in spite of careful searching we did not find it.  However, we did see 2 Bald Eagles.

The Golden Eagle has a very large territory for its 'home range' so was probably hunting over marsh areas across the border in Nova Scotia.  There were some ducks in the many streams flowing through the marsh and they were attracting the Bald Eagles.  The Common Eider shown below was seen in one stream.  A few days earlier a birder had seen an eagle feeding on an eider in this area.

Common Eider

The highlight for me was also another raptor species.  We saw two Short-eared Owls.  These owls have been seen on the marsh lately but it is unusual to see them active during the day.  We saw two of them in flight.  We did not know whether they were feeding or if they were being harassed by the many crows on the marsh.  

Pheasants and Snow Buntings were very numerous.  We saw many groups of Ring-necked Pheasants numbering at least 50 individuals.  There were several flocks of Snow Buntings, some very large.  We estimated seeing between 300 and 500 buntings altogether.  

As you can see we had a wonderful day exploring the Tantramar Marsh.  There were not many cattle pastured on the marsh but there were large round hay bales everywhere.  We did see a group of Scottish Highland Cattle on the edge of the marsh.  They were enjoying the breeze and the lush feed.

Paint Basics

Knowing Paint Better

Watercolour Paint - Daniel Smith, QoR

I have wondered for a long time about the true nature of artists paints.  I have been searching for answers to some questions about how paint functions and how watercolour, oil and acrylic paint compare.  Here is what I found out.

What makes paint dry?  What are artists paints like on a microscopic level? 

Watercolour

Watercolour paint is a solution of gum arabic (the binder) and water and microscopic-sized pigment particles.  Gum arabic is an exudate from a gum tree.  More precisely it is the sap of two species of acacia trees.  Microscopically it is a long chain that is soluble in water.  The pigment particles are in suspension in the liquid.

When watercolour paint dries the water evaporates leaving the gum arabic to become a solid which holds the pigment particles in place. You can lift dried watercolour paint because the gum arabic will redissolve in water. 

Watercolour Paint in Palette

Acrylic Paint 

Acrylic paint is a suspension of spherical polymer particles (about 1 micrometer in size) in water.  The pigment particles are also suspended in the water.  When acrylic paint dries the water evaporates, the polymer particles coalesce to form solid sheets which trap the pigment particles.  You cannot lift this paint because the polymer is now a water-insoluble solid.

Gesso is made up of water, acrylic polymer and gypsum (calcium sulfate) particles. 

Oil Paint

Oil paint is a mixture of an organic solvent like turpentine or mineral spirits and drying oil (linseed oil, tung oil) and pigment particles.  The oil is soluble in the solvent so they do not separate.  The pigment particles are so small they remain in suspension.  When oil paint dries the solvent evaporates leaving the oil and pigment on the surface.  When on the surface the oil oxidizes and becomes a solid which is no longer soluble in either solvent or water.  

Why can you put oil paint on top of acrylic paint but not the reverse?  Oil paint can be put on top of acrylic paint (or gesso) because the dried acrylic paint is essentially a plastic sheet and the oil  will bond to it.  However, you cannot put acrylic paint on top of oil paint because the dried oil paint is hydrophobic and it repels the water in the acrylic paint thus causing it to flake off.  

How do each of these paints stick to a paper/canvas substrate?  They use a process called wetting in which they form a strong physical bond with the surface.  

Why do we need gesso on a canvas before painting it?  It helps to keep the paint from absorbing into the substrate and it also smooths out the surface. 

What does water do when added to watercolour paint (oil to oil paint or water to acrylic paint)? It reduces the viscosity, which means it dilutes the paint.  If too much is added to acrylic paint, it will not harden.  When considerable dilution is desired you should use acrylic medium which contains acrylic polymer particles and so it acts the same as the paint. 

Paints usually have a fourth component termed an ‘additive’ which is used to make the paint flow well, maintain its quality in the tube, keep it homogeneous, etc.

Water Miscible Oils

Water Miscible Oil Paint is a modern invention that may be going to revolutionize the oil painting industry.  Time will tell how well it is accepted.  Right now it is just in the trial stage by most artists.  How is it different?  It can be thinned by just adding water and brushes can be cleaned in water only.  No solvent is needed.  How is it formulated so this can happen?  

The oils in oil paint are made of long-chain fatty acids.  Most of these fatty acids are hydrophobic (water repelling) so the paint is incompatible with water.  However, in normal oil paint there are normally some hydrophilic fatty acids (water loving).  If this portion of hydrophilic fatty acids is increased, the paint becomes water soluble.  Water can then become the 'solvent' for the oil paint!  Just like magic, the paint can then be thinned with water and clean-up done with water.  Organic solvents (turpentine, mineral spirits) are no longer needed.  

How does water miscible paint dry?  The water evaporates leaving the oil and pigment on the substrate.  The oil then oxidizes and hardens, trapping the pigment. 

Pigment particles 

Pigment particles are made from natural and artificial compounds which are pulverized into ultra-small particles (0.1 to 100 microns).  Some pigments are derived from naturally occurring compounds like iron oxides (ochre, umber, sienna), carbon black, lapis lazuli.  Others are from manmade pigments which are usually based on metal compounds like cadmium, chromium, cobalt, copper, lead, titanium and zinc.  When a tube of paint is labelled ‘hue’ it means that the colour will be almost identical to the genuine paint for which it is named.  However, the pigment is not the same as in the original. It is often a cheaper or a blended form. 

Golden has recently marketed an innovative watercolour paint called QoR, an acronym for ‘Quality of Results’.  They are advertising it as possessing some nice features like:  incredibly smooth transitions, good flowing while maintaining liveliness on the paper, excellent resolubility in water, excellent glazing qualities, vivid depth of colour in one stroke, greater resistance to cracking and flaking, more density of colour than traditional watercolours, and easy clean-up.  Besides these stated advantages they have marketed new  grounds and mediums to go with the paint.  These apparently increase gloss, improve flow or wetting properties, and allow you to achieve different textured surfaces.  It is exciting to be part of modern advances in paints and materials.

QoR paint has a newly formulated binder called Aquazol.  It appears that the company is keeping a tight lip on its formulation.  I have not been able to determine its chemistry but expect it is an acrylic or an acrylic/gum arabic mixture.  I have used QoR paints only minimally so far and find them bright and easy to use.  The only negative is that I have found the Aquazol has separated somewhat from the pigment in one or two of my tubes.  Time will tell how successful they are.  They are probably the forerunner in a lot of new products in the watercolour industry.

There is some discussion about QoR paints not ‘lifting’ as well as traditional watercolours.  I have done a short, uncontrolled test on my own and find that to be true.  See the photo below which shows lifting in traditional paint compared to QoR paint. The two on the left show lifting from traditional paint and the one on the right shows lifting from QoR paint.   I used the same amount of water, the same bristle brush and the same number of strokes on each followed by dabbing with dry paper towel.  It appears the traditional paints lift better than the QoR paints.  However, this is too simple a test to draw any conclusions.  One would need to do many more samples and under more controlled conditions.  I like the QoR paints and will continue to use them and time will tell how they work out.

Vagrant and Out-of-Season Birds

Unexpected Birds

Every fall we are privileged to have vagrant birds arrive here.  A vagrant is a bird that is beyond its normal range.  In other words, its presence here is accidental.  The Franklin's Gull shown below is one such species.  It appeared in a ploughed field in Ste-Marie-de-Kent last week and has remained for several days, associating with a large group of Ring-billed Gulls.

 The Franklin's Gull inhabits mainly the mid-continent of North America where it breeds.  It winters in fresh water marshes off the Pacific coast of South America.  It lives inland in North America because it likes ploughed fields and prairie land.  This trait earned it its common name,  'prairie dove'.

It is a medium-sized gull being 36-38 cm long (14"-15").  It is a black-hooded gull and has prominent white eye crescents and a slaty-gray back.  In winter the black hood is washed out with white and the bill changes from its prominent orange of the breeding plumage to black with an orange tip.

The bird which arrived here is a 1st winter bird.  Note the dark gray-brown on its back.  Older gulls would be all gray on the back.

Ring-billed Gull and Franklin's Gull

Shown above is a Franklin's Gull with a Ring-billed Gull showing the difference in size.  This Franklin's Gull was seen at Scotch Lake several years ago in the fall.  Note it, too, is a 1st winter bird.

Overbird [Nelson Poirier Photo]

The bird shown above is an Ovenbird which has been coming to a feeder in Moncton.  This species is a common warbler species seen here in summer.  It is unusual because it is still here, appearing healthy and coming to a feeder.  It normally feeds on the ground usually in the forest.  It is not a feeder bird at all.  It is called an 'oven' bird because of the domed-shaped nest it builds on the ground with a side entrance.

The season for rare fall vagrants and out-of-season birds is still upon us.  Keep a close eye for anything unusual.

Watercolour Workshops

The Storm

Recently I have had the good fortune to attend two watercolour workshops.  The most recent was presented by Peggy Holt of Fredericton.  Peggy put on a day filled with excellent instruction and demonstrations showing her work and skill.  She motivated us with her excellent teaching skills.  The session was complete with coverage of nearly every possible aspect of watercolour painting.  She even introduced some cutting edge ideas!  

The painting above was done from a photo which she used to have us paint a landscape.  I was intrigued by the severity of the storm and what it was doing to the landscape.  I enjoyed putting that on paper.

At the end of September I attended a 5-day watercolour workshop put on by the Canadian Society of Painters in Watercolour in Cornwallis, NS (see previous post).  This was a fantastic experience.  There were 8 teachers covering all aspects of watercolour painting.  Each was a master of her/his area.  We could choose to spend a day or more with our choice of 5 of them.  Some selected more than one day with some but I chose a day with 5 individuals.

Calgary Cityscape

One instructor was Rex Beanland from Calgary who specializes in cityscapes.  We had a fun day learning his techniques.  The painting above is what I was able to execute.  Getting the perspective right was the challenge.  

The symposium was also filled with extras.  We had a lobster banquet one evening.  On another we had a 2-hour presentation on Golden products.  We were shown dozens of their products with concrete examples of what they can do.  We finished the evening with lots of take-home samples.  Other extras included a life drawing session, night painting demonstration, and a welcoming reception.

I am not sure I am a watercolorist but I certainly enjoyed being shown what they can do.  Most of them are transparent and I love the luminosity they show.  It is also interesting to see what they can do by themselves as they move around on the paper.  They are a challenge to use but a rewarding challenge!

Late Birds

Saying Goodbye to Our Summer Friends

Eastern Phoebe

One thing birders often do is keep track of the dates during which species of birds are actually here in New Brunswick.  This gives us early and late dates for each species and also information about what the species is doing, its arrival and departure, its geographical locations, its movements from place to place for food, nesting, etc.  

Two species I watch carefully are the Eastern Phoebe and the Ruby-throated Hummingbird.  They feed and nest around our place and are easy to monitor.  I consider them my friends and am always sorry when they leave.  I wish them well as they wing to warmer climes each fall.  

Eastern Phoebe

The Eastern Phoebe arrives earlier than many of our migrants.  That is because it is a bit hardier than some flycatchers, of which it is one.  Its main diet is insects which it catches by flying from a good vantage point like the one on the roof above.  It also eats berries and other fruit so it can survive a bit better in cold weather when insects are difficult to find.  The last phoebe we saw here in Fredericton this year was on October 11.  We saw one later than that, on October 18 on Covedell Road near Tabusintac.

It can be a problem for flycatchers if they return too early in the spring.  If the weather is unusually warm, sometimes they will appear early.  That is fine if some insects have hatched providing food.  If, however, the weather turns bad and there are no insects about, it can be difficult for our phoebes.

Ruby-throated Hummingbird Female

Another species I watch carefully for early and late dates is the Ruby-throated Hummingbird.  They arrive almost every year on Mother's Day weekend.  Sometimes it is a day or two on either side, but I can usually depend on having visitors to our hummingbird feeders on Mother's Day weekend.  They usually leave around Labour Day weekend.  This year we saw our last hummingbird on September 23.  I still have my feeders out in case an unusual hummingbird shows up looking for food.  That is very unlikely but it has happened in NB before in late fall and in almost every case the hummingbird has been a rare species.  One time it was a Rufous Hummingbird and one time it was a Broad-billed Hummingbird.  You just never know what surprises our avian visitors have for us.
