Lost British birdsong discovered in New Zealand birds

Recordings of New Zealand yellowhammer accents enable scientists to hear how their British relatives might have sounded 150 years ago

A new study reveals that a type of native birdsong, now lost in Britain, can still be heard in New Zealand where the birds were introduced in the 19th century.

By comparing recordings of yellowhammer accents in both countries scientists were able to hear how the birds' song might have sounded in the UK 150 years ago.
