7 things homeowners do that drive birds away
That's why folks like Jeff Walk, a science director for The Nature Conservancy, teach classes on how to attract birds to our yards.
And why David N. Bonter, assistant director of Citizen Science at the Cornell Lab of Ornithology at Cornell University in Ithaca, N.Y., works with the birding community across the nation to track and assess how various bird species are faring.
Yet the ironic thing is this: We may say we love birds, but many of us unthinkingly go about our daily routines in such a way that we literally force birds to blow the coop, whether that be a country home, suburban townhouse or city apartment.
Bad for birds
Here are things guaranteed to shoo the birds away, as identified by Walk and Bonter, and what you can do to rectify the situation.
Lawns: "Lawn is evil," said Bonter, noting birds will fly elsewhere if more than 25 to 30 percent of your property is lawn. "The more shrubs you have and the more grasses you let grow up, the better you are going to be in attracting them." Even trees and shrubs that look sickly can provide needed habitat for birds.
The more pavement on a property means even fewer trees and shrubs to provide shelter or food, he said.
Cats: "Cats kill millions of birds in North America every year," Bonter said. Walk agreed, noting cats can pose a particular threat to migrating species who might not be as cat-smart as the street-wise birds in your neighborhood.
Chemicals: Pesticides and insecticides kill weeds and insects, both important food sources. Walk encourages property owners to "tolerate" a bit "of rambunctious wildness" in their yards for the birds' sakes. Millions of birds are also killed through accidental poisoning from chemicals and other spills, he added.
Plate glass windows: "Plate glass is the most effective device devised by humanity to kill birds," Walk said. "Birds collide with the windows because they see the reflection and think it is open space." As many as 1 billion birds are killed by window strikes each year.
What to do? Put up something in the window, like reflective tape, that will send a visual cue to the bird that the space ahead isn't clear for flying.
Feeders in wrong place: Bonter said those situated next to big bay windows are hazardous because birds can fly into the glass and die or be injured. Placing them in areas with large cat populations and no cover also poses a risk. "People may be trying to attract birds, but they're literally setting up a trap," Walk said.
No water: Birdbaths kept consistently clean and filled with fresh water are avian magnets.
No native plants: Native plants offer the type of shelter and food local bird species need year-round.
Map your yard
Relive the glory days of your seventh-grade science fair without leaving the comfy confines of your own home with a new interactive "citizen science" project called YardMap. You'll help the experts at the Cornell Lab of Ornithology at Cornell University keep track of birds and bird habitats across the country.
In so doing, you'll likely find out how your property is acting -- or not -- as a haven for various bird species, says Rhiannon Crain, project leader of the lab's YardMap Network in Ithaca, N.Y. That's important. Researchers believe habitat quality not only affects which birds show up in your yard but impacts bird reproduction, she said.
Using YardMap is easy. Sign up at the project website, yardmap.org, watch a short tutorial video and you're off.
YardMap uses Google map satellite imagery to let you see your property and "fill in" all the various features, from houses to sidewalks to ponds to vegetable gardens and lawns. You can map single-family homes, condos, apartment buildings, your local schools or community gardens.
Lab scientists will be able to use that data in their work on bird habitats, Crain said. You'll be able to "peek" over a virtual fence to see what others in your region are doing with their lawns and whether they attract more interesting birds than you do.
"A lot of people are taking these more wildlife-friendly gardening practices to heart," Crain said. "People will see they're not alone."
