               Exotic Species

             Aviculturists, game farms, and zoos care for and breed a vast array of waterfowl species, not all of
             which are native to a region or even a given continent. Because many of these birds can fly, escape
             is always possible and does occur. Some species may adapt well and thrive, while others die from
             starvation or exposure in an environment to which they are not suited. Exotic species compete and
             often conflict with native species. If a facility admits a patient that is not native to the area, do not
             release it even if it was found in the wild. Finding a captive placement for the bird with a zoo or
             game farm is the best solution for the individual bird and for the future of native wildlife.

             In honor of E95, a Trumpeter Swan, an early member of the State of Wisconsin Trumpeter Swan
             Reintroduction Program and Raptor Education Group, Inc. patient. He changed our world and will
             always have a place in our hearts. Thanks to the State and Federal programs, aviculturists, and
             conservation groups that continue to contribute to habitat and species preservation, assuring a
             place for our magnificent waterfowl.
