On this page we present sample sounds and sonagrams (showing frequency spectra) from two of the bird species we work with. Both species have elaborate songs which are the result of sexual selection.
The sedge warbler: Acrocephalus schoenobaenus
|
|
|
The male sedge warbler has one of the most complex songs known to science, described as an 'acoustic peacock's tail'. Songs are analysed by computer and shown in the form of a sonagram (above). Click the 'Waveform' button for an alternative view. |

The canary: Serinus canaria

The male canary also has a complex song, and the computer allows us to generate artificial songs (example above) used in playback experiments to captive females. |
