Abstract
A five year survey of mortality in an Ontario waterfowl park was conducted. The highest mortality rate was in birds under seven weeks of age, with infectious disease most frequently diagnosed. In older birds, amyloidosis and gout were most common. Associations were found between the presence of amyloid and the diagnoses of gout, enteritis, and arthritis. Specific data collection requirements for studies of this type, and the difficulties involved, are outlined. Recommendations for increasing productivity, including the implementation of sanitation programs, and improvements to the record-keeping system, are made.
