The Silver Gull has a white head, tail and underparts, with a light grey back and black-tipped wings. In adult birds the bill, legs and eye-ring are bright orange-red.
They are found at virtually any watered habitat. Birds flock in high numbers around fishing boats as these leave or return to the coast, but seldom venture far out to sea.
The silver gull novaehollandiae'') is the most common gull seen in Australia. It has been found throughout the continent, but particularly at or near coastal areas.
It is smaller than the pacific gull, which is also found in Australia.
The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages , but is a much larger, robust gull with no overlap in range.
