Bewick's wren

Bewick's wren - its numbers are in decline.
My first encounter with the very vocal Bewick's wren was back in 1997 on a canoe trip to the Broken Islands.  I did not see another one again until a few years ago in a conservatory near Nanaimo.  Today, for the first time, I saw a number of them in a marsh near my home.  This wren is not terribly pretty - most wrens are somewhat drab in appearance - but are remarkably vocal.  This is another thing most wrens have in common; they chatter a lot.

I remember seeing a Pacific wren a few years ago atop an enormous cedar tree.  Between its diminutive size and distant placement it was hardly visible, but its song filled the woods.  Other wrens I have seen include the marsh, winter, and rock wren.  Winter wrens are year-round residents here.  The distinctive ticking sound facilitates an easy identification.  My favourite characteristic of all though is the telltale angle at which their tailfeathers point up when they are perched.

There are a number of factors at play which are affecting the numbers of wrens.  Invasive species like the house finch (European finch) are partly responsible as they drive other species away from natural sites that, in turn, drive away Bewick's wrens.  Changing climate is another factor which has just started to play its hand in affecting the distribution of birds of all species.  Then there is habitat loss.  As we increase in numbers and require more land for either living or growing food there is less habitat for wildlife.  These three factors are costing a terrible toll on our native plants and animals.

Harjit Bahia - Science teacher and colleague from Garibaldi died August 2, 2024

You will be missed Mr. Bahia.  You made a difference and we are sad you are gone. I keep in loose contact with my fellow retired teachers from Garibaldi Secondary School.  I talked with my long-time friend, Mike Lynch, today, and discovered that Hargit died over the summer.  Unbeknownst to him, he had an underlying heart condition and passed away after working out on his treadmill.  The date was August 2, 2024. I was shocked to hear this.  He was only 49 years old, turning 50 some 3 months later.  It was a shock to everyone, for he was loved by all who knew him.  As a teacher, Mr. Bahia was kind and fun.  He contributed to students in many ways and was always available to help those in need.   For myself, I knew him as a fellow science teacher and taught in the adjoining room to him.  He was always available to help, share ideas, and work together.  Easy to approach, I found that I could talk to him about anything and appreciat...

The passing of a generation

Image
Kathryn's mom and dad with our children, Josh and Leanne. A generation, for North America, tends to be between 20 and 30 years.  During that time a couple will give birth and raise children to see them repeat the pattern as they themselves have done.  Each generation has its own set of standards, values, and ideals based upon their experiences and culture, and some of that is passed down to their offspring.  What changes are the life experiences of the following generation and the new customs and ideals that are blended together as a couple becomes a family. Kathryn's mom passed away a few days ago, she was predeceased by her husband several years ago.  Both of them were the grandparents of my children, the mother and father of my wife, Kathryn.  It was my pleasure to know them and to love them as my own, for to me they were Mom and Dad.  And they were there to welcome my children into the world just as my children were with them in spirit when they left it...

I found a black widow spider in a plant pot today

Image
The spider I found is a western black widow spider, one of three species of black widow that occur in North America.  The fact that this one has another red patch on the back of its abdomen above the spinnerettes tells us that it is an immature individual. The one thing that people know about black widow spiders is that they are extremely poisonous.  Their venom is something like 15x more toxic than that of a rattlesnake.  The saving grace is that there is very little venom injected from a black widow bite than what a rattlesnake can deliver.   The good news is that black widow bites seldom lead to death.  You are more likely to suffer nausea, muscle pain, and swelling around the bite.  Symptoms usually last only 12 hours or so.  Death may be a result in people with compromised immune systems or in the very young or the elderly.   In 2018, it was reported that there were 1015 cases of people bitten by black widows.  Of those, there ...
