Habitat Loss: A Preventable Disaster

Your gas tank is almost empty. The last place you stopped, the pumps were dry.  You know another place –it is miles away, but you should be able to just make it. When you get there, the filling station is gone, replaced by a parking lot. Now what?

If you were a bird with this scenario, you would probably fall to the ground, too exhausted and too hungry to travel on. If you were lucky you might find enough water, food, and shelter to recover and travel to your breeding or wintering grounds. If not, you, and possibly your whole flock, would die, never to fly again. This is happening throughout the US. Indeed, according to a study recently published in Audobon Magazine, the Evening Grosbeak population has plummeted by 91% since 1967, due to rest stops and watering holes on their flyways being poisoned by pesticides, drained and plowed for crops, or made into strip malls.

Habitat loss is the number one cause of bird deaths. There are fewer and fewer places for birds to perch and feed, raise their young, and find open water.  Distances between resting and refueling stops often become so great that many birds traveling thousand-year-old migration routes will die from lack of water, food, and safe stop-overs.

How can you help? 

There are a number of things you can do at home to help reverse this alarming trend:

• If you must cover a ditch, offer water and shelter to replace that which you have eliminated.
• Have a sick tree, or one you fear in your yard? Make a snag out of the bottom twenty feet or so. Dead trees will shelter cavity nesters, and provide food too; and it is fun to watch the birds that use them. Trees are the lungs of the earth, so plant a tree or fruiting bush to replace what you took away.
• Don’t make your gardens so clean that they become sterile for wildlife. Gardens that don’t have bugs, can’t feed birds, salamanders, garter snakes, frogs, dragonflies, or any other wildlife.
• If you clear an area, don’t do it between March and August. Wait until Labor Day, by then the young have left their ground nests.
• Keep a hedgerow of weeds along an edge or corner of your yard. Make a brush pile for hiding and escape routes for birds.  Brush piles, and brambles provide shelter during the winter cold also.
• When you change the landscape to suit your tastes, ask yourself who and what you are depriving of water, food, and shelter.

Unless you are willing to face a Silent Spring, you need to provide the four necessities: water, food, shelter, and a place to raise young. You can make a difference. Start now!
