Harriet the tuneful donkey 'sings' in an octave normally reserved for opera singers when a regular visitor turns up with treats in Galway, Ireland.
This is the astonishing sound of Harriet, the donkey with a very distinctive call.
She's never really sounded like other donkeys, say visitors to her paddock and now they are comparing her high-pitched tone to that of an opera singer.
Martin Stanton, a regular fan of hers, visits Harriet with treats near his home in Galway, Ireland.
