Scientists ponder impact on species after finding singing adjusted to cope with urban din.
The noise of city life is dulling down the song of our famously musical tui. The colourful, scrappy birds are among the few native species to have adapted to humans disrupting their environment, and one researcher is now trying to understand what changes they've made to survive.
Tui are renowned for their wide repertoire of songs - it's been estimated at more than 300 - yet we're only just beginning to find out how urban environments are influencing their singing behaviour.
As with all songbirds, the melodies of tui are used to select a mate and an impressive song can make a male more attractive to a female during breeding season.
Suspecting that tui tailor their singing patterns to fit with the constant racket of city life, Massey University researcher Dr Weihong Ji and colleagues set out to investigate song differences between tui at spots around Auckland.
