Information about the Bird Silver Gull

The silver gull should not be confused with the herring gull, which is called "silver gull" in many other languages (scientific name Larus argentatus, German Silbermwe, French Goland argent, Dutch zilvermeeuw), but is a much larger, robust gull with no overlap in range.The silver gull (Chroicocephalus novaehollandiae) is the most common gull seen in Australia. It has been found throughout the continent, but particularly at or near coastal areas.

The South African Hartlaub's gull (C. hartlaubii) and the New Zealand red-billed gull (C. scopulinus) were formerly sometimes considered to be subspecies of the silver gull. As is the case with many gulls, it has traditionally been placed in the genus Larus, but is now placed in the genus Chroicocephalus.
The head, body, and tail are white. The wings are light grey with white-spotted, black tips. Adults range from 40-45cm in length. Mean wingspan is 94cm. Juveniles have brown patterns on their wings, and a dark beak. Adults have bright red beaks-the brighter the red, the older the bird.
Silver gulls are found in all states of Australia. It is a common species, having adapted well to urban environments and thriving around shopping centres and garbage dumps.
Silver gulls have twice been recorded in the United States; one bird was shot in August 1947 at the mouth of the Genesee River, Lake Ontario, and another was photographed in Salem County, New Jersey, in autumn 1996. Both are now believed to have escaped from captivity.
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.
Breeding occurs from August to December. The nest is located on the ground and consists of seaweed, roots, and plant stems. The nests may be found in low shrubs, rocks and jetties. Typical clutch size is one to three eggs.
