About These Birds
Belted Kingfisher
The belted kingfisher is unusual in that the female is more colorful than the male, sporting an additional rufous belly band. These noisy birds announce their territory with a distinctive rattling call. They excavate nesting burrows up to 2.4 meters deep into riverbanks using their heavy bills.
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。
