Around the turn of the twentieth century, North American conservationists embarked on an intensive campaign to prevent the Trumpeter Swan (Cygnus buccinator) from following the Passenger Pigeon into extinction.

Etiologic Diagnosis

The purpose of this study was to characterize the incidence and diagnostic features of amyloidosis and other diseases found at necropsy in captive trumpeter swans ( Cygnus buccinator). A search of Iowa State University's Department of Veterinary Pathology and Veterinary Diagnostic Laboratory databases yielded 31 trumpeter swan ( C. buccinator) necropsy cases from captive swans in protected habitats. Eleven of the 31 birds had amyloid deposition most commonly in the spleen (8 of 11), liver (7 of 11), and kidney (6 of 11) and less often in the pancreas (2 of 11) and adrenal gland (2 of 11). Amyloid deposition effaced normal tissue with adjacent necrosis and hemorrhage in severe cases. Amyloidosis was most often diagnosed in February and March. Other disease diagnoses in the trumpeter swans included aspergillosis (5 of 31, 16%); bacterial infection (5 of 31, 16%); lead toxicosis (3 of 31, 10%); gout (2 of 31, 6%); parasitic infection (2 of 31, 6%); vitamin E deficiency (1 of 31, 3%); trauma (1 of 31, 3%); and ventricular foreign body (1 of 31, 3%). Histopathologic, toxicologic, and microbiologic analyses did not define an etiologic diagnosis in the deaths of 9 trumpeter swans. In these cases, necropsy lesions included emaciation (5 of 9), enteritis (1 of 9), pulmonary hemorrhage (1 of 9), and no lesions (3 of 9). The number of trumpeter swan case submissions was greatest in January and February. This study provides a reference for veterinary diagnosticians concerning incidence and diagnostic features of amyloidosis and other diseases in captive trumpeter swans of the midwestern United States.

Dominant Activity

The use of breeding and wintering areas has been a focus of studies on trumpeter swans (Cygnus buccinator), but the importance of migration stopover areas has been overlooked. We conducted a behavioural study to assess trumpeter swans' use of spring-migration stopover areas in southern Alberta, Canada. Adult swans foraged for 48% of the day, preened for 12%, rested for 26%, and were involved in locomotion for 14% of the time. Cygnets foraged for 49% of the day, preened for 15%, rested for 19%, and were involved in locomotion for 18% of their time. Temperature had a significant effect on the time budget of trumpeter swans: below –4°C, foraging diminished and sleeping was the dominant activity. The dominant activity of trumpeter swans in spring-migration stopover areas was foraging. We therefore suggest that these stopover areas are important for building the energy reserves required for successful migration and breeding.
