Common Nature

It would be nice to see pictures from your area too. Even if your yard is small, you might consider a photo walk through a local park.

I'm curious, about how big is your yard? Postage stamp like the 8x10' I've seen in front of near-downtown-Chicago townhouses, or the 1/10 to 1/8 acre in most cities, or the "national average" 1/4 acre yard?

Small city yards -- even homes with just a patio or a balcony -- have their own wildlife value. They can function as a tiny oasis. If you can only do one thing, put out water, like a birdbath or a barrel water garden. If you have any outdoor space at all, and it's shady, then you can make a moss garden with bricks, rocks, or statues. But there are lots of options.
