This is really quite an odd sight. Heading back to the jetty on Penguin Island, we saw two Mute swans paddling towards us. Penguin Island is a short ferry ride from Rockingham on the mainland but still not really where you expect to see these birds. There is a small breeding colony at Northam (about 100 km away) but this pair has been seen in the Rockingham area recently.
Mute swans are an introduced species in Australia.
