is the culmination of Roni Horn's long-running photographic series of taxidermied Icelandic wildfowl. Photographed at close range against white backgrounds which recall conventional studio portraiture, the birds are viewed from behind, abstracting their varied physiognomies and markings into inscrutable shapes and patterns. Despite the title's singularity, the birds in this series are presented as diptychs in order to compare and contrast different species. This gesture of doubling-as an aesthetic and conceptual strategy-has been a consistent motif for Horn since 1980, serving to invite careful scrutiny from the viewer. Horn's images are accompanied by a text from writer and curator Philip Larratt-Smith. In place of the usual catalogue essay, Larratt-Smith has compiled an extended series of quotes and anecdotes from film, literature, photographers' monographs and Horn's own writings.
