About These Birds
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。
Northern Gannet
The northern gannet is a spectacular plunge-diver, folding its two-meter wingspan into an arrow shape to hit the water at up to 100 km/h. Air sacs under the skin and a reinforced skull protect it from the impact. Bass Rock in Scotland hosts over 150,000 gannets, the largest single colony of any seabird in the world.
