A Supersize Mural Honors Peterson’s Famous Silhouettes
Many bird watchers remember the neat black silhouettes in the endpapers of the classic Peterson’s field guides—an eloquent reminder about the value of size, shape, and posture. Now, the Cornell Lab’s visitor center echoes those pages in a magnificent 40-foot-high mural painted by James Prosek. Featuring 170 birds, the mural celebrates biodiversity and challenges viewers to identify both the familiar and the unusual. Watch this video showing the mural coming to life.
