There's the top twenty five woodies. NOW that don't mean I'm running home to plant manzanita and prickly pear; no usagae in my area on those two. And this doesn't account for grasses and forbs and perennials. But pick the ones that grow in your area and add them to the yard, and you WILL get more birds (ask any of the folks with wildlife gardens I put in...)
I did woodies because they do more to create housing as well as food sources. And I included the poison ivy to show you that it doesn't matter what we like in a garden; wildlife has it's own ideas...
