At one stage while travelling along the south coast of Yorke Peninsula we pulled off the main road and drove down a rough dirt track towards the beach (see photo below). A solitary juvenile Pacific Gull was feeding on the sand. This species is found along coastal NSW, Victoria, Tasmania, South Australia and southern Western Australia. While it is widespread it is not present in large numbers in most places. It is usual to see only one or two birds at a time.
The photo above shows the bird in the juvenile plumage which indicates a first year bird. For the next 3 years a variety of plumages stages can be seen, from the chocolate brown through to mottled brown and white until the full adult plumage is developed. Below I have included several photos of two birds in adult plumage at Victor Harbor earlier this year.
