Here is the description from Granger's web site.
"12ft Recovery Sculpture This is an enlarged version of the 8ft wing of a Pintail duck in the recovery position (which itself was an enlarged version of a life-sized sculpture, which we use as the background image of our website). This is the second stainless steel version and was cast in October, 2012 in Pennsylvania. It will be installed outdoors at a museum near the Breakers hotel in Palm Beach, Florida."

His wooden sculptures of birds in flight are enough to take your breath away, too.
