About These Birds
Great Cormorant
The great cormorant is one of the most widespread seabirds in the world. Unlike most waterbirds, cormorants lack fully waterproof plumage, leading to the iconic pose of standing with wings spread open to dry. In Asia, cormorants have been used by fishermen to catch fish for over a thousand years.
House Sparrow
家麻雀是全球分布最广的鸟类之一，与人类关系极为密切。雄鸟头顶灰色，喉部黑色，翅具栗色。广泛分布于城市、农村和郊区，以谷物、种子和昆虫为食。因人类扩张而随之传播至世界各地，但近年来在某些地区种群下降明显。
