While waiting for the bus, now that it’s light out that early, I like watching the birds. They have complex interactions and so many different styles of flying. They have ways that are a closed book to our species. From human eyes they seem so playful that it’s difficult to believe they participate in a struggle for survival. Evolution tells a different story, of course. Living not far from the great human nest of Newark’s Liberty Airport, it’s not unusual to see an engineered flying machine soaring high over their avian heads. Which, I wonder, are the better fliers? Birds, after all, evolved. Flying wasn’t planned, as far as we can tell. Although not so much around here, some birds don’t even fly.
I once read—many years ago and I can’t recall where—that if a person were to fly they would need an enormous chest to beat the very large wings they’d need for lift-off. Birds, apart from being naturally aerodynamic, have hollow bones which make them a touch fragile, but less tied to gravity. Our planes and jets, unlike the escape vehicle in Chicken Run, don’t flap. Bernoulli’s law keeps them aloft, along with some meticulous engineering and heavy fuel consumption. Humans may imitate nature, but they supersede it when they can. Still, I have to wonder why, if birds were a special creation as our literalist friends claim, God didn’t make them more like a plane.
Holding your wings out stiff all day, I’ll allow, would get pretty tiresome. Still, if you’re designing a critter to fly you might as well go with the best parts available, right? If not, I’m going to have a talk with my mechanic and ask for some of my money back. Birds, for all their charm, are very good illustrations of evolution at work. Dinosaurs taking to the air is so poetic that it has an organic feel. Flying is a great way to escape your land-bound predators. That step from long leaping to flying may be a doozie, but it seems to explain the shape of birds better than any intelligent design. Among bipeds, though, only one claims the place of being god-like in shape. Having said that, there are some flaws that a good biomechanical engineer might address. But then, who said God majored in engineering? When I went to college I was firmly under the impression that he’d majored in religion. And that, as many engineers might suppose, is for the birds.

As Christmas nears so does a warm front, dashing hopes of a white Christmas in New Jersey. Well, at least there are no tornadoes coming. The weather, as my readers know, has long been perceived as a divine barometer. In a time when patience is wearing thin with religion, and weary headlines ask if it will ever finally disappear, our animal cousins seem, as usual, to pick up on clues more readily than we. An article on the BBC science page describes how a set of tagged golden-winged warblers vacated their nest a day before a tornado struck. Scientists suspect that the birds—and likely other species of birds as well—picked up the infrasound of the tornadoes that is well below human hearing range. Sensing the danger, they flew nearly a thousand miles, stopping just south of the storm’s track.
Of course, tornadoes don’t last an entire day. If the birds fled that long in advance, they couldn’t, I suspect, have heard a tornado that hadn’t formed yet. Since I’m no scientist, I’m not really qualified to offer an explanation, but I do wonder if such behavior isn’t related to consciousness. Several books that I’ve read recently have explored the concept of animal consciousness, and although we are reluctant to admit them to the realm of the self-aware, I wonder how long we can deny it. No doubt, if the birds fled (and returned after the danger had passed) there was an intentionality to their actions. Jealous of our intelligence, we must find a way to explain that animals can predict natural disasters of many kinds long before humans detect their more obvious traits. Our technology gives us seconds, or minutes, of warning. Dogs, cats, and birds know well in advance. But we are the superior beings here.
One of the problems with consciousness is that we can never get outside our own. Other people act in ways similar to us, and describe similar mental states, so we assign them the same kind of consciousness we have. Animals, not using human language, also act in similar ways to us. We call it “instinct” and continue on to the truly important stuff. I have no idea if birds can detect infrasound; I wouldn’t be at all surprised if they could. Without the ability to place it in the context of danger, however, I doubt they would take a thousand mile vacation just after their annual migration. We could learn a lot from our fellow creatures, if only we’d admit them to the conscious club and not the food club. And perhaps they might be able to explain to us why, despite all we know, religion never seems to go away.
