It’s long been known that the undersea noise we create with our large machines — oil drilling equipment, ships and submarines — has a detrimental effect on whales, causing hearing damage and changes in feeding, mating and communication. And noise from snowmobiles has often been cited as the reason some species of animals in Yellowstone National Park are being stressed and pushed out of their preferred habitats, impacting their health and increasing mortality.
It turns out that our large machines, though, may not be our only cause for concern when it comes to outdoor noise pollution and its effects on the natural world. Our small, compact mobile phones — and the apps we put on them — have been shown to change the behavior of birds.
Will the noise we individuals are increasingly capable of imposing upon other species outdoors soon also have enough power to affect their ability to survive?
Whether you’re an avid sportsman or purely a wildlife-watcher, it’s a fact that the animals, birds and fish you endeavor to see are “paid for” mostly by hunters. Those who engage in hunting, fishing and trapping are the major contributors to conservation funds in almost every state. Surprisingly, the monies animal-viewers and birdwatchers donate to conservation efforts rarely add up to even a third or a half of what hunters put into department of natural resources funds — even though watchers greatly outnumber them.
In my own state of Wisconsin, deer-hunting licenses and permits generated $22.7 million in revenue for the department of natural resources in 2010. And in most years, an excise tax on hunting equipment provides an additional $10 million to the state for wildlife management — in one case, supplying $400,000 to study and prepare for the likely arrival of a deadly bat disease. The problem is, however, that the number of hunters — along with anglers and trappers — is declining. And it promises to keep decreasing as the population ages.
So as the economy tightens, causing state and federal budgets for wildlife conservation to continue to be cut, and if younger people are not taking up hunting and fishing, where will future environmental monies come from?
One in five Americans considers himself or herself a “bird watcher,” according to a report published by the U.S. Fish and Wildlife Service last summer. Going by the report’s guidelines, in order to qualify as a “bird watcher,” you either had to have taken a trip one mile or more away from home for the primary purpose of watching birds, or you had to have closely observed birds around your house. If you mostly spotted birds passively — while mowing the yard, for example, or while at a zoo — you would not be counted as a “bird watcher.”
As I hiked with my dog through prairie open space on a recent morning, we were both captivated by the wild creatures around us. In his case, it was the prairie dog colony; in mine, a long V of geese honking overhead. The swallows have left, and I haven’t heard a meadowlark since early September.
