1. Shrink the lawn and go organic. Lawn chemicals kill bout 7 million birds each year. Manage your lawn organically and reduce it by 25 percent to favor plants that provide seeds and a nesting place for birds.

2. Collaborate with neighbors. Create a wildlife corridor that birds can travel through by linking uncultivated areas of your yard with other in the neighborhood.

3. Keep cats inside. Hundreds of millions of birds are killed each year by household and stray cats.

4. Grow native plants. Native birds are adapted to eat the seeds and berries of native plants, but 20 percent of our North American plant species are in decline.
