Create a humane backyard

The nation's largest and most effective animal protection organization, the Humane Society of the United States, is best known for campaign to reduce the suffering of dogs and cats. What does the group think about backyard bird-feeding? They think it's a great idea.

"One of the best ways to enjoy wildlife in the comfort of your home is to watch birds at a feeder," the Humane Society said in one of its online guides. "You'll be amazed at the variety of birds that will come to your feeder throughout the year."

The Humane Society explains, "The general rule for feeding any wild animal is: do not feed when it might cause harm. With birds, there are few situations in which we can imagine harm being caused, so we say, go ahead!"

The Humane Society raises these points:

1. Bird-feeding is most important when birds need the most energy, such as during migration or in spring and early summer, when natural food sources are depleted especially in winter. One exception to that rule is the hummingbird. They should be offered nectar from spring through fall because of their high metabolism.

2. Place feeders in locations where birds will not become prey to cats. The Humane Society said cats should be kept indoors for their own safety as well as wildlife's. An estimated 3.7 billion birds are killed by predators, including feral cats and outdoor pet cats. You can protect birds from cats by placing feeders 12 feet from bushes or evergreens where a cat might hide. That way, the bird easily can fly to safety when it sees the predator.

3. Prevent birds from colliding with windows. You can help by placing feeders either 30 feet away from a window or within 3 feet of the window. (In the latter case, a confused bird won't build up enough momentum to harm itself.) Consider hanging streamers or window decals to deter collisions.

4. Use more than one feeder. Some birds feed on the ground while others feed from platforms on the ground. 

5. Make sure to keep your feeders clean to prevent disease that could harm birds.

6. Don't worry if you stop feeding briefly during traveling or vacationing. In all but the most severe weather, birds will find food in your absence, particularly if you live in suburban areas.

7. Don't feed birds bread. It has no nutritional value for birds; moldy bread can harm them. Never offer birds food containing chocolate. It is toxic to birds. Don't feed birds table scraps. They may not be safe or healthy for birds; most table scraps will attract mice or rats.
