#1 Way to Attract Birds to Your Backyard
I’ve been experimenting with my California cottage garden, planting native plants, adding water features, and putting out bird seed. If you’re wondering how to attract birds to your backyard, these steps are a great start. As a result, my garden is alive with bird activity and song every single day.
But recently, I discovered something that tops all other strategies: caterpillars.
Why Caterpillars Are Key for Birds
It’s spring, and my garden is literally raining caterpillars. I just came inside to find four tiny wrigglers hitching a ride on my clothes. I’m thrilled—not because I’ve always loved caterpillars, but because birds need them.
Most bird species rely on caterpillars, especially when feeding their babies. Bird parents need hundreds of caterpillars daily to nourish a nest full of fledglings. By supporting caterpillars in your garden, you’re helping sustain healthy, thriving bird populations.
Understanding this is a huge step in learning how to attract birds to your backyard naturally.
The Secret: Keystone Native Plants
So how can you attract more caterpillars—and therefore more birds—to your backyard? The answer: keystone native plants.
A one-hundred-year-old oak (Quercus) graces my patio, its branches brushing my bedroom windows. Oaks are keystone trees, hosting over 400 species of caterpillars.
Other keystone trees in the USA include:
-
Cherry (Prunus)
-
Willow (Salix)
- If you are thinking – I don’t have room for a Huge tree in my garden – read on.
Even if you don’t have space for a large tree, herbaceous natives like goldenrods, asters, and sunflowers also provide food and shelter for insects, which in turn feed birds. Planting these is a simple, effective way to learn how to attract birds to your backyard.

Caring for Your Bird-Friendly Garden
Caterpillars depend on their host plants for the early stages of life, then drop to the soil or leaf litter to cocoon. To support them:
-
Avoid planting a lawn under your trees and bushes
-
Leave some leaf litter for cocooning
-
Add ground cover or beds of compatible native plants
These simple practices help ensure your keystone plants support the full lifecycle of insects, sustaining birds naturally.
Small Actions, Big Impact
Adding even one or two keystone plants can transform your backyard ecosystem. Birds, insects, and other wildlife will flourish, increasing biodiversity and making your garden more eco-friendly.

Your Backyard Can Make a Difference
No matter the size of your garden, you can help wildlife thrive. Grow keystone plants, support caterpillars, and leave your garden a little wilder. Birds will thank you, and the planet will too.
Go get a new native, caterpillar-loving plant from your local nursery or botanical garden—and watch how your backyard comes alive with birds. Practicing these steps is the most effective way to consistently attract birds to your backyard and foster a thriving ecosystem at home.

Thank you so much for that. How cute indeed. I have a thing for clothespins . . . I don’t however like caterpillars. As you say, they stick to you and some are poisonous, so I have always told my girls to not touch them. I am glad birds love them though.
I really think this way of thinking about what you can do in your little garden to benefit the planet is very important and empowering. I see so much that people do wrong in their gardens, really just trying to conquer nature instead of facilitating it. These neighborhood covenants in so many places in America will fine you if you don’t “clean up” your leaves in the fall for example.
