Waterfowl rehabilitation: A primer for veterinarians

Ducks, geese, and swans are an easily recognized group of birds. There are approximately 50 native species in North America, all of which are considered migratory. Despite being a legally hunted family of birds, native waterfowl are federally protected, and there are federal laws associated with their rehabilitation, disposition of nonreleasable animals, and disposal of carcasses. In the United States, there are several nonnative species found with increasing frequency that many don’t realize are feral exotics. There also are state laws dealing with owning exotic waterfowl and prohibition of their release. Native waterfowl occupy a variety of wet habitats, have unique feeding requirements, have specific enclosure and substrate needs, and should be treated by someone with expertise to ensure recovery sufficient for return to the wild. If a practitioner is going to accept wild waterfowl as patients, it is important they know the laws, identify species, understand species natural history, and learn about associated common problems. This article discusses legalities, basic husbandry issues, common presentations, and basic veterinary/rehabilitation matters of waterfowl commonly found by the public. It also covers some common problems seen with feral exotic waterfowl as well.
