Althea Sherman Chimney Swift Bird Tower
The 90 year old tower was erected on the Historical Society's Bickett-Rate Preserve on May 7, 2013 and restoration of the tower is underway. The bird obervation tower, constructed by pioneering ornothologist Aletha Sherman in 1915 in National, Iowa, stands next to Edgewood Hall, an farm1836 house on the Bicket-Rate preserve that looks very similar to the Sherman House that once stood in National. Sherman built the bird tower to observe chimney swift birds. Her design enclosed a 2x2 artificial chimney with doors, windows and peepholes that allowed her to study the birds.
