At the Zoo was written by Paul Simon and released by Simon and Garfunkel as a single in 1967, later appearing on their 1968 album Bookends. The song playfully imagines the animals of New York's Central Park Zoo with human traits, a gentle joke that helped it stand out from the duo's more serious folk songs. It has endured through oldies radio, film and television use and nostalgic playlists, and it is often shared alongside their better-known work, including Hello darkness, my old friend, by listeners revisiting the duo's 1960s catalogue.
