On feathered wings: birds in flight.
New York: Harry N. Abrams, 2008. Quarto, dustwrapper, colour photographs.
This book features the work of seven photographers who have spent their lives camping out, donning waders, and lying in wait for the greatest shots of birds doing what they do best: flying! Selected by birder and photographer Richard Ettlinger, these gorgeous, often thrilling images show hunters, migrators, waterfowl, and songbirds living on the wing: hunting, feeding, fighting, travelling, or just gliding along. An essay by Ettlinger gives an overview of the mechanics and evolution of bird flight.
