In 1931, an attempt to force Stroud to discontinue his business and get rid of his birds failed after Stroud and one of his mail correspondents, a bird researcher from Indiana named Della Mae Jones, made his story known to newspapers and magazines. A massive letter campaign and a 50,000-signature petition sent to President Herbert Hoover resulted in Stroud being permitted to keep his birds, and despite prison overcrowding, he was even given a second cell to house them. However, his letter-writing privileges were greatly curtailed. Jones and Stroud grew so close that she moved to Kansas in 1931, and started a business with him, selling his avian medicines.
