She recognized more than ninety years ago that loss of habitat was the fundamental cause worldwide of the decline in numbers and species of birds. Sherman would no doubt be heartsick today to see yards shaved just one or two inches high, roadsides mowed edge to fenceline, streams straight and naked, and prairie and forest nearly everywhere supplanted by beans, corn, and cattle. She could not have imagined miles and miles of malls, superhighways, grandiose homes, and housing developments. In 1915 Sherman drew wide attention with her design and creation of her twenty-eight-foot-tall, nine-foot-square chimney swift tower, which enclosed a two-foot-square wooden chimney, a winding staircase from bottom to top, and four floors or levels.

Once she reached her Iowa acres, she launched her most impressive and innovative bird study. Hiring a local contractor, she laid out her plans for building a chimney swift tower. Three carpenters constructed the original structure in 1915. Made of white clapboards to match the house, it was nine feet square and twenty-eight feet tall. An artificial chimney of rough pine was built inside, two feet square and extending fourteen feet down into the tower.
