The weather had been wet and windy when Wong Kais arrived at Victor Harbor in May 2023. The water at Encounter Bay had seen beautiful waves wash in and locals had spent many days board paddling. On 6 June 2023 the winds stopped howling and water in the bay was calm and still. At 1250h he noticed two black blobs floating on the sea. Using his binoculars he identified them as musk ducks, Biziura lobata menziesi. He is unsure of their genders as male musk ducks are devoid of the large bill lobe outside of the breeding season.
Musk ducks are usually sighted in fresh water bodies where reeds are present to facilitate nesting.
