The first step toward certifying your garden is to provide birds and animals with the things they need most: food, water, shelter, and a place to raise their young. Just as important is avoiding the use of chemical fertilizers, herbicides, or pesticides. With compost, fish fertilizer, neem oil and insecticidal soap, I am able to feed and protect the garden while feeding and protecting the wildlife I've invited to be here.
Food sources include seeds, nuts, berries, nectar, and native plants. In my yard, I provide two bird feeders and use a wild bird seed mix that includes sunflower seeds. The small birds (sparrows and finches) eat the small seed and toss the sunflower seed to the ground for the squirrels. I also provide two nectar feeders for the hummingbirds and butterflies. Most summers I have an abundance of apples, plums, black currants, raspberrries, and blueberries that I don't mind sharing. So far, no one has been a glutton so they leave enough for me to eat and freeze.
Shelter and a place to raise young are both provided by dense shrubs and trees for nesting. Over the years I've had sparrows, robins, and finches build nests in the garden. While I'm not sure where the squirrels are giving birth, I do have a couple of mama's who bring their young as soon as they're ready to forage for food.

There's been a few surprise visitors to my garden - some that I'd rather wouldn't make it a habit to stop by. The little brown rabbits are adorable, but hard on the vegetable garden. Wiley C. Coyote wants to make a meal of the other critters, including my pet cat. And, the blue herons will eat every fish and frog in the pond if I don't shoo him away. I try to remind myself that we all have our place in the food chain. Even so, I keep a protective eye on the cat.
The most unusual visitor so far is this guy...
