形态特征
澳洲银鸥大体上是一种长约42厘米的洁白的鸥，但翼、背及尾是淡银灰色的，飞行时翼端的黑斑和亚缘的白翅斑明显。成鸟的喙、腿及眼圈都是深红色的。异性相似，仅雄性的喙稍大。幼鸟上体及翼有灰褐色斑点，腿及喙以至眼圈稍黑。

生活习性
澳洲银鸥分布于整个澳大利亚大陆及沿海。属于鸥形目鸥科，最最常见的澳大利亚游禽。现在已经从野性水鸟变成与居民有某种依存关系的鸟了，一般景区内随处可见。

Description
The head, body, and tail are white. The wings are light grey with white-spotted, black tips. Adults range from 40–45 cm in length. The mean wingspan is 94 cm. Juveniles have brown patterns on their wings and a dark beak. Adults have bright red beaks—the brighter the red, the older the bird.

Distribution and habitat
Silver gulls are found in all states of Australia, as well as New Zealand and New Caledonia. It is a common species, having adapted well to urban environments and thriving around shopping centers and garbage dumps. Their successful adaption to urban habitats has seen their population increase in areas of human activity, with the availability of nesting grounds the only limiting factor on population growth.
