Dick the Mockingbird was the name of one of U.S. president Thomas Jefferson's pet birds. Although there had been previous presidential pets, Jefferson is thought to be "the first president to have a pet [that lived] in the White House..."[1] Prior to his term in the Oval Office, Jefferson bought his first mockingbird in November 1772 from a slave of his father-in-law John Wayles for five shillings.[2][3] Birds were Jefferson's favorite animal and Dick was the favorite from among at least four mockingbirds the president had while in office.[3] During his time in the White House, Jefferson wrote observations on the types of birds that he spotted in the area. In May 1793, in response to a letter from his son-in-law Thomas Mann Randolph,[3] Jefferson wrote: "I sincerely congratulate you on the arrival of the mockingbird. Teach all the children to venerate it as a superior being which will haunt them if any harm is done to itself or its eggs."[4]
