Is it permissible for a phone ringtone to be the sound of an animal or a bird instead of music?

It is permissible, from a Sharia perspective, to use an animal sound as a phone ringtone, and this is practically feasible. It is obligatory to change phone ringtones away from impermissible musical tones, based on the saying of the Prophet, peace be upon him: "I have been forbidden from two foolish, immoral sounds: a sound at the tune of the devil's flute, and a sound at a calamity and the devil's wail."
