A band of giant birds (dwarfs in mascot-type suits) that sings the blues-rock version of the show's theme song during the end credits of the 1969 Sid and Marty Krofft TV series H.R. Pufnstuf.
Dunno know if they were ever in an actual episode.
Lady Boyd (Sharon Baird) was the Tina Turner-inspired lead singer. The band's name is an obvious spoof of real band The Byrds.
