Hitting a bird while driving
Hitting a bird while driving is upsetting, and it is rarely the driver's fault: birds judge an oncoming car by its distance, not its speed, so at highway speeds they take off too late. The moment shows how old instincts fail at new speeds.
What it may mean
A bird on the road seems to have plenty of time. It sees the car coming, waits, and then lifts off right into the windshield. Researchers who tested this with simulated vehicles found that brown-headed cowbirds began their escape at roughly the same distance however fast the vehicle was going. Against a hawk, that rule works well. Against a car at highway speed, it leaves the bird far too little time. Carelessness has nothing to do with it; the bird is using an instinct built for a slower world. People do the same thing with email, news, prices and changes at work, judging by how close something looks rather than how fast it is coming. The thud against the windshield is sad, and it carries a plain lesson about speed: some threats need an earlier start than your gut suggests.
Depending on how you saw it
A bird lifting off just in front of you
Many birds feed on roads and shoulders, picking at spilled grain, grit, insects and roadkill, and fly up only at the last moment. Most get away, and the near miss leaves your heart pounding. Which close call this week reminded you to slow down?
A thump on the windshield
Many birds hit by a car glance off and fly on, and a driver at speed rarely sees which way they went. Stopping on a busy road to look is often more dangerous than the hit itself. When is it wiser to drive on safely than to stop for something you cannot fix?
A large bird such as a hawk or vulture
Big birds need more time and room to take off, so hawks and vultures feeding on roadkill are especially at risk from traffic. Braking gently and steadily is safer than swerving. When is a steady, predictable response safer than a dramatic one in your own life?
Why it happens in nature
Many birds feed on or beside roads and take off only when a vehicle is close. In tests with simulated vehicles, cowbirds started their escape at about the same distance whatever the speed, so at higher speeds they often left too late. Drivers seldom have time to react, and braking smoothly is safer than swerving.
