Mountain Bluebird in Lake Country, BC


You will find mountain bluebirds in open country with sparse trees.  I have seen them three times now, all sightings have been in grasslands dotted with the occasional tree.  I photographed a bluebird chick a few years ago while visiting Drumheller, Alberta.  You can see it in the image below.


All bluebirds are cavity nesters.  They readily take to holes found in trees and nest boxes.  The problem is that those nesting sites are often desired by other birds such as house sparrows and starlings, both introduced species that have caused the decline in certain bird populations.  Fewer nesting sites means a declining population.

Fortunately, bluebirds readily take to nest boxes.  The problem is with keeping unwanted species out.  Building birdhouses with an oval hole instead of a round hole tends to dissuade house sparrows and starlings.  Another method is to build a slot at the top or bottom of the house to enter.  A narrow slot of 1-1/8th inches is often enough.  There are plans online (click here) to build them yourself or you can buy them prefabricated.

Thanks for reading.

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 were no deaths, but 5 people had potentially life-thre

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.   We ourselves have

Henry Fair - A good man lost to us all.

Image
There is a great deal I have always appreciated about Henry Fair.  The first thing that comes to mind when I think of him is that he was kind.  He always had time, always expressed himself well, and always cared for kids.  I think that's the second thing that comes to mind; Henry had a great passion for kids.   His devotion to helping others was best illustrated by his time spent teaching alternate learning at Garibaldi Secondary School.  KOALA (Kids On Alternate Learning Aims) was a program for at-risk youth that Henry ran for many years.  He was compassionate and understanding towards those under his purview and treated everyone with the same degree of care and professionalism.   One of the more amazing things about Henry was that nothing seemed to phase him.  I can tell you from experience that a remedial program will test the patience and metal of anyone, yet he never let it get to him.  Every student was valuable to him and worth his time and effort.  He was a constant advocat
