Cool Days for Baby Robins

Everyone knows what robin’s egg blue looks like. We often use that term to describe a pretty shade of blue, perhaps on some piece of clothing or a paint colour, but I think it looks best on the shell of a robin’s egg. I found this half shell two days ago on a cold miserable day when the little bird that hatched out of this shell probably wished he were back inside it.

It is a testimony to how tough the robins are, when they risk nesting so early. It is also evidence that they  need as long a growing season as possible for the young birds to grow to adulthood before the fall.

I took this picture of the egg shell when the sun was shining through the living room window for a few minutes that day.

Later I took another picture with the robin’s egg on a piece of white paper, next to a chicken egg as a size comparison. Somehow the “robin’s egg blue” colour looked more faded and greener. What a tiny egg it is, when you consider that the baby bird will grow to be the size of a robin.

“That’s my boy,” the robin chirps. “He’ll grow up to look just like me!”

As a point of interest, this photo of the robin in the dogwood was taken on April 29, 2016.

This year on April 25, this same dogwood tree is just getting tiny leaves and there is no hint of flowers yet. What a difference in temperature. It’s a very long, cold spring this year.

Dogwood Time

Straight out from my bedroom window, in our dogwood tree, a little robin sang, “Winter’s over. We survived another one!”

Did you know that the Pacific dogwood is the provincial flower for the province of British Columbia? Its flowers have four to six petals. That in itself is unusual, as probably the most common number of petals for flowers is five.

While researching the number of petals on a dogwood, I came across the term “Fibonacci Numbers.” The number of petals on most flowers is one of the Fibonacci numbers, but the dogwood only sometimes complies. The Fibonacci number sequence is named for Leonardo of Pisa, also known as Fibonacci, for introducing the concept of these numbers to the western world in the early 1200s.

The Fibonacci sequence is 0, 1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144 …

Can you guess what the next number is going to be?

I was amazed at how it works. The next number is always the sum of the previous two.

I think someone used this sequence to figure out the rate at which rabbits breed. I think, too, that Fibonacci must have done his research in my backyard.

Math and nature are so connected, it never ceases to amaze me.
