Twitchr is an on-line soundmap for bird-song and an offline series of bird listening walks created by artists Kathy Hinde & Ed Holroyd. The soundmap is interactive and can be played like a scrolling muscial score to generate new bird-song soundscapes. The walks include a talk by an invited expert.

TAKE PART by uploading a birdsong recording at www.twitchr.co.uk or come on a twitchr walk. Twitchr bird-recording-walks are organised to bring people together to listen and record birdsong.

Twitchr was first commissioned by Somerset Arts in November 2009 and relaunched at MOVE exhibition at Peter Scott Gallery, Lancaster Arts in January 2019.
