Solar-powered running water for the bath. Sustainable wood for the home. Recycled milk jug feeders. The rise of eco-friendly products for the birds in your backyard has taken off faster than a hungry hummingbird.

"People, especially bird watchers, want to do the right thing for the environment," says Bill Thompson III, editor of Bird Watcher's Digest in Marietta, Ohio. "They prefer to feel good about the products they buy and use." Here are a few bird-beckoning backyard fixtures that should leave with a clear conscience.

Bath time

Among the most popular new trends are solar powered pumps for birdbaths. One by Birds Choice retails at around $90 and has a battery backup in case the day is overcast.

"It has two functions," says Henrik Lehmann Weng, chief executive officer at Wild Bird Centers in Glen Echo, Md. "One is that birds are attracted to the moving water, but also breaking surface of the water will break the development of mosquito eggs."

Dinner is served

Bird feeders have gone green, says Freddy Howell, owner of the Wild Bird Center of Los Gatos, Calif. One recycled plastic milk jug feeder by Bird's Choice is called the hopper, where seed goes in the top and comes out the bottom, just like a grain hopper. The hopper retails for $55 and up, while less expensive feeders made of recycled lumber go for as low as $25.

Shelter from the storm

Howell sells a growing number of handcrafted domiciles by local artists, an eco-friendly option that uses recycled materials and reduces transportation pollution from out-of-state manufacturers.

"I have some artists that use recycled wood, such as end pieces from other milling and recycled fence boards, and some that use driftwood," Howell says. "I also have a line from a local artist that uses downed trees and hollows out the inside."

Gourd shaped birdhouses, which may retail from between $25 and $40, are also popular for purple martins, chickadees, bluebirds and many others. Some are made of hollowed-out gourds, which Howell says are easy to decorate and have a natural look. These gourds may only last a few years, while others are made of more durable material.

Despite the tough economy, Weng of Wild Bird Centers says his industry is experiencing an increase in sales as much as 12 percent. He links this to the staycation trend, which may be causing people to spend more on their backyards and, by proxy, shelter for birds.
