Full story here, with video. Very, very odd.
"'This is Yellowhammer," says Marcus Coates excitedly, pointing at a video of a man with a paunch reading a newspaper over breakfast. Suddenly, the man's eyes dash from side to side. His chest twitches up and down, and he bursts into an orgy of twittering and tweeting. "He sat there singing for an hour and 10 minutes," says Coates. "Watch: his mannerisms are so bird-like."
Yellowhammer is one of a cast of characters Coates has created for an extremely odd video installation, to be shown at Baltic in Gateshead next month. Dawn Chorus, which recreates the sound of birdsong using human voices, is an ambitious project, with scientific as well as artistic goals - medical research charity the Wellcome Trust sponsored him, and the birdsong has been archived for researchers."
