About These Birds
Common Kestrel
红隼（Falco tinnunculus）— 广泛分布于欧洲、亚洲和非洲的小型隼。以悬停空中寻觅地面猎物的行为为特征。
Emu
The emu is the second-tallest living bird and the largest bird native to Australia. It is the only bird with calf muscles, enabling powerful running at up to 50 km/h. In the famous Emu War of 1932, the Australian military was deployed against crop-raiding emus — and the emus arguably won.
