When Feeding Birds, Think Safety and Health

Feeding birds is a popular way to watch wildlife during the winter months. But many bird experts say the experience is often more pleasant for people than for birds. And it might even put wild birds at risk.

“Feeding birds is not necessary for their survival1 except in extreme weather conditions,” said Stephen Kress. He is with the National Audubon Society, an organization whose aim is to protect wildlife. “Feeders can definitely2 help them get through that kind of weather.”

Most birds eat insects and show little interest in bird feeders. For those birds, Kress suggests growing native plants in a natural environment.

In addition, birds who do eat seed “will be more likely to come to feeders if there is some cover nearby.” This lets them feed and then fly to protective3 areas, such as in trees.

The most common mistake people make with their bird feeders is incorrect placement. They put feeders in places where birds are frightened by foot traffic, risk being hurt by cats, or risk flying into windows.

Kress likes the idea of setting4 up a bird feeder at least one meter away from a window. That way, if a bird gets frightened, it won’t die when it hits the glass, he says. And, he urges owners of cats to keep them inside the home so they can’t hurt the birds.

Learn which bird species5 are common to your neighborhood so you can avoid feeder wars and understand the social order.

“Some birds are more aggressive at feeders,” Kress said. They eat a lot and do not leave much food for other birds.

A solution is to put the food in more than one place by using different kinds of seeds and feeders. Nyjer seeds, for example, are a favorite of goldfinches. Tube feeders with wire covers prevent large birds from entering.

Pay attention to seed quality and freshness. Unprotected seed left too long in feeders will turn moldy7, and mold6 can kill wildlife. Refresh8 your feeders every few days and clean them often with a liquid of 10 percent bleach9.

Adam Rohnke is a wildlife expert with Mississippi State University. He said people can feed birds more effectively by using black-oil sunflower seeds, as it is the favorite seed of feeder birds. The added value, he said, is that it reduces waste seed on the ground, which appeals to other small animals.

Rohnke also said that bird lovers10 can increase the number and diversity of birds by using different kinds of feeders. For example, some birds, such as doves11 and towhees, live close to the ground. So they like lower feeders.

Other birds like other things. Woodpeckers, blue jays and songbirds, for example, like suet, a hard fat in meat. Orioles, bluebirds and waxwings like fruit.

Another word of advice: Do not feed wild birds anything salty, like potato chips, or food that could choke them, like plain bread.

Always try to provide a supply of clean water, but use care when looking for the right birdbath. Most birdbaths are too deep for birds, Kress said. Putting a few large stones in the water can give the birds a place to sit.

And, for hummingbirds12 – which are very, very small – put water on large plant leaves to attract them. Hummingbirds like to bathe in leaves, Kress said.
