The images above are all from Ghosts of Gone Birds, a recent exhibition of outstanding contemporary work curated by Ceri Levy at the Rochelle School in East London (2-23 November 2011): both an activist conservation project involving almost 200 artists, and an attempt to 'breathe artistic life back into extinct bird species' through each artist adopting a particular disappeared bird.
In addition, the exhibition aimed to raise awareness of and money for the BirdLife Preventing Extinctions programme.
The title of this post combines the names of two exquisite pieces of work from the exhibition: Alisdair Wallace's 'Ghost Flock', and Andrea Roe's 'Last Song: The Grand Cayman Thrush'.

For a fine blog post that sets Ghosts of Gone Birds alongside two other recent exhibitions - Katri Suonion's 'Bird Hospital' at the Kuopoio Art Museum in Finland, and Bill Burns' brilliant 'The Museum of Safety Gear for Small Animals' at the Arnolfini in Bristol - see Sue Palmer's 'To the window flown' in her Inquiline here.
