Goodbye winter. Hello spring. Another round
of setting clocks ahead is behind us as well as all the rant on social
media about why we continue with this practice. Some people blame farmers for screwing
with our circadian rhythm, but they're not the culprits. Cows and crops rely
on the sun. Not clocks. Maybe that’s why Saskatchewan ignores time change.
In 1895, George Hudson, an entomologist,
made the first attempt to introduce time change. He wanted the world to go
ahead two hours in the spring so he could hunt bugs in daylight after his day-job
ended. He was unsuccessful with his request.
Time change kicked in during WW1 and WW2
to optimize daylight hours and conserve energy. After each war, it was up to
jurisdictions to decide whether they stuck with it. In the
winter of 1974, permanent daylight-saving time came into play and children
started walking to school in the dark. Hello logic.
But now I’m over time change and have moved onto hello spring. The hunt for the first crocus, first dandelion sighting and of course watching birds as they construct or renovate their nests.
I checked some of my favourite nesting
sites. Unfortunately, the great horned owl's home was gone. When I found the pile of
sticks scattered at the base of the tree, my heart sank. Great horned owl parents raised their
fuzzy owlets here for over a decade.
I went down the Google rabbit hole to determine whether owls rebuild in the same place. What I read, shocked me. Owls typically do not build their own nest. What? How did I not know this? They apparently take over a suitable nest from another bird and spruce it up to their liking. I’m a huge owl fan. Should I think less of them for being opportunists? Or more of them for conserving their energy?
Later that day I discovered owls aren't the only opportunists. A ballsy Canadian Goose honked at me from it's perch high in the tree. Last spring a bald eagle lived there with an unobstructed view of the Bow River. Maybe I have never given geese enough credit. Maybe they are smart.
Cowbirds don’t steal nests. They merely deposit their eggs in an already
furnished home. If the eggs in the nest she selects are white with beige
specks, the cowbird will lay her eggs with the exact same colour pattern.
After the cowbird lays her eggs (sometimes as many as six) in the unsuspecting nest of, let’s say, Mrs. Red-Winged Blackbird, she might peck tiny holes in the host’s eggs. This way her chicks won’t have to compete for food or attention. When Mrs. Cowbird leaves, she doesn’t go far. She sticks around for a while to keep an eye on her eggs.
Mrs. Cowbird may be a negligent mom, but she wants to make sure Mrs. Red-Winged Blackbird has adequate mothering skills. If she dares to push out any of Mrs. Cowbird’s eggs, well, female cowbirds have a way of getting even. She will return to the nest when it’s unattended and toss out the original eggs.
When Mrs. Red-Winged Blackbird proves she’s a worthy foster mother, Mrs. Cowbird flies away to enjoy her freedom. In just a few weeks, she’ll flit her wings at another dashing male cowbird and the process repeats itself. As for her young, they grow up knowing they're cowbirds without their mother ever being around.
Nature is fun and funny.
And Mother Nature has a wicked sense of humour. She can still turn on the snow-switch randomly for a few more months.

No time change in Arizona either. But it wreaks havoc on the TV program grid coming from other states. I didn't know that birds other than the cuckoo laid their eggs in other birds' nests. Thanks for sharing.
ReplyDeleteCow birds! UGH! Didn't know that about the owls. And, as for time changes, I wish someone would put an end to it...Spring ahead is, literally, a killer by way of a statistical increase in car accidents and heart attacks.
ReplyDeleteCanadian geese nesting in trees? Never heard of that! Great photos, Barbara.
