When I was at Audubon we created some great resources to guide landowners in helping birds and wildlife on their exurban or country yards and property. The best resource was a workbook that I can’t find online anymore, so I’m posting a copy for you to download here.
In addition, we made a poster (below) with some good ideas. Unfortunately the links on the poster don’t work anymore, but you can find the Rural Birds to Help section here at Urban Birdscapes, and you can Google some of the other topics for good info. You can still download the poster or even order hard copies from the Natural Resources Conservation Service (Audubon created these resources for NRCS with an earmark from their budget).
