GoKawiilStudy 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.
