Due to large scale clear cut logging practices and other activities detrimental to breeding success of white-throated sparrows, this boreal forest nesting sparrow has had a significant decrease in its population. Articles worth reading about this topic include: www.oiseaux-birds.com/card-white-throated sparrow.html, www.nrri.umn.edu/mnbirds/wtspa2.htm, and www.wisconsinbirds.org/plan/species/wtsp.htm. The Minnesota ornithological periodical, "The Loon" prints graduate student articles on wildlife. Searching their index probably would result in an article or two on white-throated sparrow declines. Not sure how many Ohio graduate students are doing research on birds, but these articles, I believe, would be a great addition to The Ohio Cardinal.
