Hi Roger
Yes, floating nesting platforms have been used for swans, but this is an individual attribute as to whether the swans will use a floating nesting platform in a wild setting if they are more comfortable or familiar with nesting on the banks or in grasses of a waterway. Since each habitat has its own unique qualities as to what may safely work (i.e., current speed, tethering requirements, etc., we would recommend you contact Wendy Hermon, Coordinator, Swan Support in Datchet. Wendy knows the various areas and the materials that may be applicable to your situation. We hope this information is of benefit. The Regal Swan
