Researchers use synthetic birdsong to revive sparrows' lost song dialect

A team led by physicist Gabriel Mindlin at the University of Buenos Aires generated a computer-recreated version of a rufous-collared sparrow song last documented in a Buenos Aires park in the 1960s. After playing it back to local birds, a sparrow began imitating parts of the song within about three months. The work is part of broader research into how declining bird populations lose access to the songs needed for mating and territory defense.

Study confirms UK birds sing in regional dialects, from yellowhammers to blue tits

Researchers studying birdsong for International Dawn Chorus Day found that species such as blue tits, blackbirds, great tits, woodpigeons and yellowhammers show clear regional and even individual variation in their calls. Woodpigeons' familiar phrase changes syllables depending on location, while yellowhammers split into two dialects across the UK, distinguished by pitch differences in the final notes of their song.
