One of the most beautiful gulls is the Silver Gull (Chroicocephalus novaehollandiae or Larus novaehollandiae) - the most common gull in Australia. It has been found all over the continent, but especially in or near coastal areas. It is smaller than its fellow Pacific Gull (Larus pacificus), which also lives in Australia. The silver gull has a sharp voice consisting of a variety of calls. The most common call is a harsh, high pitched kwarwh. The silver gull naturally feeds on worms, fish, insects and crustaceans. It is a successful scavenger, allowing increased numbers near human settlements.
