If you're irritated by Greensleeves and bored with Mozart's Symphony No. 40, it might be time to go for the roar of the African lion or the underwater call of the orca - and give to charity at the same time.
A new range of mobile ringtones featuring animal sounds ranging from the cuckoo to the mountain gorilla is on sale on the Orange website, with 10 per cent of the proceeds going to the World Society for the Protection of Animals.
The ringtones, by Retro Ringtones, cost between £1.50 and £3.00 and are made from recordings taken in the wild. Orange says sales are "very encouraging" and should continue to grow.
A spokeswoman said the lion was most popular so far, followed by the chimpanzee, the orca (killer whale), the Siberian tiger and the mountain gorilla.
"The lion is probably more of a masculine thing. I wouldn't like it much if it went off behind me in a dark alley at night," she said.
Orange decided to give a cut of sales to charity as part of its corporate social responsibility programme. At the moment, the animal ringtones are only available to Orange customers, but the offer will eventually be extended to users of other networks.
