Being nocturnal, bats search for food at night, but their night vision is fairly poor. So instead they use echolocation, or reflected sound, to home in on insects such as moths. Their built-in sonar directs them to the precise location of the tasty morsels; then it’s just a matter of swooping in and gobbling them up.
So the bats’ prey have to be crafty as well.
Certain species of tiger moth have the ability to emit sonar of their own. As a bat is closing in, the moth emits a fusillade of ultrasonic clicks. This barrage blurs and disrupts the bat’s echolocation: the signal is essentially jammed. The baffled hunter can no longer “see” the moth, and is tricked into thinking its target has vanished. Thwarted, the hungry predator flies away, and the prey is safe.
Our little tiger moth beats its enemy at its own game.
Wouldn’t it be nice if we could “jam the signal” of the enemy of our soul? If we could disrupt and counter the lies the world tells us about ourselves?
Is there a colour more exquisite than robin’s-egg blue? If there is, I’m not aware of it.
To me, the tiny oval of a robin’s egg is perfection itself. Its soft blue-green hue seems to evoke a feeling of serenity. And the shape of the egg itself, all gentle curves, seems to echo this calmness.
I’d love to keep it that way forever, just so, and never see it broken.
There’s only one problem with this: if the egg stayed intact, a baby robin would never be born.
Sometimes we have to break something we cherish for an even more beautiful thing to come into being.
Did you know that some birds and bees can see things that are completely invisible to us? They’re able to see in infrared, just beyond the wavelengths of the visible light spectrum that human eyes can detect.
What looks to us like a regular pink flower might resemble a helicopter landing pad to a bee. Where we see only the uniform expanse of one colour, the bee may see a target-shaped design of several differently coloured concentric circles. The bee’s infrared vision allows it to home in on the most nectar-rich part of the flower.
The world looks completely different when you can see in infrared.
I sometimes think that God sees us in “infrared.” He can see things in us that are invisible to others, and even to ourselves.
We humans can’t help but react instinctively to a beautiful smell, can we?
In my last post, The Perfect Recipe for Bread, I mentioned how wonderful the smell of freshly baked bread is in your own home. The same is true when you bake a cake, cook a roast, light a scented candle, or when you bring a bouquet of flowers inside: the aroma fills the whole house and gives you a deep sense of pleasure.
You get the same pleasing effect when you take a walk in your neighbourhood and can detect cooking smells emanating from houses as you pass by: here someone’s making a rich stew, over there a spicy curry. Even better is strolling by someone’s garden and being enveloped by the scent of the lilacs or roses growing there.
But what if a beautiful aroma could permeate an even bigger area?
Once the worst of this pandemic is over, psychologists warn that many of us may suffer from post-traumatic stress for some time to come. Some of us will have lost a job, seen our business close down for good, suffered isolation and loneliness, or may have even lost a loved one during the COVID-19 crisis.
But is PTSD a given in these circumstances? Is there different outcome that can occur, an unexpected benefit that may arise out of these difficult times?
Psychologists say yes: there’s such a thing as post-traumatic growth. It’s been found in survivors of war, cancer, and natural disasters. Some people emerge from a crisis with increased spirituality, a greater sense of personal strength, new priorities and closer relationships with others. What could have broken them actually made them better.
This phenomenon reminds me a bit of “sea glass.” Sea glass, or beach glass, found washed up on shores, starts out as merely cast-aside pieces of broken glass. Perhaps they’ve been tossed overboard from a ship, or thrown into the sea from land along with other garbage.
These shards of glass endure years of being buffeted against the stones of the sea bottom. It seems like they’re being dashed about mercilessly by the relentless action of the waves. Surely no good could come of this?
During this worldwide crisis, many of us are concerned about the changes that are being wrought by the COVID-19 pandemic. We wonder what the world will look like once we emerge from the lockdowns.
Will life truly return to the way it was before? Will there be thousands of small businesses that will never reopen? Will we ever be able to gather in large crowds like we did in the past? Will the way we “do life” have changed permanently because of this pandemic?
It’s at times like these that we need something that never changes, much like conifers. During the winter, when deciduous trees are bare, I’m thankful for coniferous trees. These loyal friends, like the spruces, pines and firs, still have their mantle of green, which they’ll keep year-round. These silent sentinels might not be flashy, but we can count on them not to change.
The lockdowns associated with the coronavirus pandemic have produced some unexpected results in the natural world.
With fewer vehicles and industrial machines operating, noise pollution has been reduced so dramatically that seismologists can hear sounds from inside the planet that they couldn’t detect previously.
In cities, reduced traffic noise is allowing people to hear birdsong, the chatter of squirrels, and the chirping of crickets like never before. People have been surprised to discover that they can now hear the flapping of birds’ wings as they pass overhead.
A quieter environment is probably also allowing animals to hear each other better. City birds usually have to sing more loudly than their country cousins to make themselves heard above the urban cacophony: perhaps their mates and rivals can hear them more easily now. With a reduction in ship traffic, marine mammals might also be finding that they can contact each other with greater ease now that there is less “acoustic smog” in the oceans.
If we can hear the creation better during the lockdowns, and creation can hear itself better, can we hear our Creator better?
For over a century, two marble lions have guarded the main branch of the New York Public Library at Fifth Avenue and 42nd Street in Manhattan. These majestic stone creatures flank the entrance to the building, keeping careful watch over all who enter.
During the 1930s the library lions were officially named “Patience” and “Fortitude” by then-mayor Fiorello LaGuardia. He felt that those names embodied the qualities that New Yorkers would need to survive the Great Depression of that era.
If ever there was a time when New Yorkers (and indeed all of us) again need patience and fortitude, it’s during the COVID-19 crisis. New York has been struck particularly hard by this pandemic, but they are pulling through in large part thanks to the selfless health care workers who have done their utmost to guard the health and welfare of those under their care.
We still need guardians, don’t we? Particularly during times like these.
During the past week hundreds of millions of people around the globe have been told to “shelter in place,” a phrase normally reserved for natural disasters or violent attacks. In today’s context, it means to stay at home for a certain length of time to help prevent the further spread of COVID-19.
Good advice. But what if it’s your heart that needs shelter? Where can you go when you need protection from emotional distress?
The Bible speaks of a shelter that believers can turn to when events threaten to overwhelm us:
Sometimes the sweetest things take the most effort to produce, don’t they?
Take, for instance, maple syrup, one of Canada’s iconic products. We often use it atop pancakes or waffles, or in desserts (see below). This delicious liquid starts out as sap collected from sugar maple trees.
Right now it’s maple syrup season in Eastern Canada: as the weather warms, the sap in the trees starts flowing freely. Holes are drilled into the trunks of the maples, and buckets or tubing collects the dripping sap, which is then transported to a central location.
And then it’s ready to be bottled, right? No! Actually, the process has only just begun.
