William A. Bird was an architect who worked in Birmingham in the early 1890s. He kept offices in room 4 of the Hewlett Block as early as 1891 and advertised his experience working on buildings for Southside Baptist Church and on St Paul's Cathedral. He was listed among the new members accepted into the American Institute of Architects in Birmingham in January 1893.
By 1904 Bird was living and working in Chihuahua, Mexico. He worked on the Palacio Federal in that city, and designed a church for the Episcopal Parish of St Mary, and a bathhouse at the resort of Santa Rosalia. He also supervised construction of the dam at Boquilla de Talamantes.
