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。
Keel-billed Toucan
The keel-billed toucan is the national bird of Belize and one of the most recognizable birds in the Neotropics. Its oversized bill, which can be a third of its body length, is actually very light due to its hollow honeycomb structure. Toucans roost communally, with up to six adults squeezing into a single tree cavity.
