Owlharp

An Owlharp is a specialized stringed instrument, designed to be played by birds of prey, held steady by a wing and plucked by the talons. So far, the only character in the series to use one was Asio Bardwing, who played and sang rather poorly, so it is unknown what a properly played owlharp would sound like.
