According to information found on the internet: “The mechanical eagle, a well-known Stony Brook Village landmark, was installed in the pediment of the post office in 1941. The wood-carved eagle with a 20-foot wingspan flaps its wings on the hour from 8:00 a.m. to 8:00 p.m. daily. It is synchronized with the clock on the cupola of the federalist style post office situated in the heart of the Stony Brook Village Center.”
