The Livingston Ripley Waterfowl Conservancy, located in Litchfield Connecticut, is home to a number of endangered ducks.
Although all the images are of captives, they roam freely on the 16 acre preserve.
Swans, cranes and geese reside in open fields while most of the ducks and teal have small ponds that are enclosed with netting.
Many thanks to Ian Gereg, Executive Director of the conservancy, for the opportunity to photograph his charges and for all the information included in this gallery.
