Invasive species the Red-billed Leiothrix also threatens to change Britain's dawn chorus.

A new study led by UK Centre for Ecology & Hydrology warns the bird could become as familiar as Ring-necked Parakeets, whose numbers have rapidly increased since becoming established in this country in the 1970s.

Dr Richard Broughton, from UKCEH, tells Carrian Jones there have been a cluster of sightings of the Red-billed Leiothrix around Frome.
