James Edward Heath (born October 25, 1926), nicknamed Little Bird, is an American jazz tenor saxophonist, and the brother of bassist Percy Heath and drummer Albert Heath.
Jimmy originally played alto saxophone but after the influence of Charlie Parker on his work for Howard McGhee and Dizzy Gillespie in the late 1940s, he earned the nickname "Little Bird" (Parker's nickname was Bird) and he switched to tenor sax. 
He returned to work with Miles Davis in 1959. He went on to introduce John Coltrane to Miles. Then with Kenny Dorham and Gil Evans. He recorded extensively as leader and sideman. During the 1960s, he frequently worked with Milt Jackson and Art Farmer.
