Imagining a new world sparrow brings about that old form, a brownish bird smaller than a robin, moving about in flocks; a bird mostly unnoticed and unheralded—not a bird often enthusiastically photographed, or one most people would go to great lengths to see. For those trying to keep track of sparrows, you could witness at least 20 different species in Wisconsin. For those keeping track of sparrows, the subtle variations in coloration, song, and habitat make for interesting study.
Take the Lincoln’s sparrow, for instance, with its overall buffy chest, light brown streaking fading to all white on the breast, a buffy mustache and eye ring, and gray eyebrow. None of these characteristics on its own necessarily makes a Lincoln’s sparrow, though a careful study of the combination of characteristics will reveal a Lincoln’s. The problem, at least for observers, is that the Lincoln’s sparrow rarely makes appearances unobstructed. When it does, the bird quickly drops to the ground at any appearance of a threat. Thus, the Lincoln’s sparrow is one of the more difficult sparrows to observe in Wisconsin.
