These incredible bird houses have been made and photographed by the group calling themselves London Field Works. Click here to see more of them. We haven't seen these in situ yet, but we really want to. This is how London Field works describe what they do:
London Fieldworks was formed in 2000 by artists Bruce Gilchrist and Jo Joelson as an umbrella organisation for creative research and collaboration at the art, science and technology intersection. Typically, their projects engage with the notion of ecology as a complex inter-working of social, natural, and technological worlds.
