agriculture and birds

Learn about the links betwen agricultural practices and changing bird populations. A brief overview is here at National Audubon's website, and a paper from the Journal of Applied Ecology is given here as a pdf. Yet another paper from the Royal Society for the Protection of Birds is linked here. Penn State's website has this article. Not all of these are recent papers, but they provide a set of introductory concepts and research results. Click on the Penn State ag magazine to find pdfs to previous articles. Finally, a NRCS paper is available here.
