形态特征
白脸鹭是一种体型细长的中型涉禽，体长60-70厘米，体重550克。嘴长而尖直，翅大而长，脚和趾均细长，胫部部分裸露，脚三趾在前一趾在后，中趾的爪上具梳状栉缘。成鸟相对其他鹭科鸟类要小，正如它的名字，很容易通过白脸鹭的蓝灰色身体和独特的白脸来识别。雌雄同色。

生活习性
尽管白脸鹭不迁徙，但它在当地确实会季节性活动，有时可以长途飞行。 在新西兰，白脸鹭通常在冬季迁徙到内陆，而在澳大利亚，它们往往在繁殖季节向内陆地区迁移到淹水湿地，并且在繁殖季节之外的沿海地区。
白脸鹭在飞行中是一只优雅的鸟，缓慢地拍动着深蓝色的翅膀，与大多数苍鹭相比，它们更经常飞行，颈部伸展。虽然通常是独处的，但为了保护间隔很大的觅食地，白脸鹭偶尔在觅食时组成松散的小群体，栖息时会有许多只聚焦在一起。

Description
The White-faced Heron is mostly light blue-grey in colour, with a characteristic white face. In flight, the dark flight feathers of the wing contrast with the paler grey plumage, making this bird easily identifiable when viewed from below. It has a long, slim neck and a pointed grey-black bill. The legs are long and dull yellow in colour. Sexes are similar. When breeding, the birds have long feathers (nuptial plumes) on the head, neck and back. The White-faced Heron has a slow bouncing flight. Young White-faced Herons are similar in appearance to the non-breeding adults (no nuptial plumes), but are duller, with little or no white on the face. They often have a reddish colour on the underparts.
Distribution
White-faced Herons are the most commonly seen herons in Australia. They are found throughout the mainland and Tasmania, and most coastal islands. They also occur in Indonesia, New Guinea, New Caledonia and New Zealand.
Feeding
The White-faced Heron feeds on a wide variety of prey, including fish, insects and amphibians. Food is obtained in a variety of ways, such as walking and disturbing prey, searching among damp crevices or simply standing in the water and watching for movement.
