About These Birds
American Robin
The American robin is widely regarded as a harbinger of spring across North America. Despite its name, it is a true thrush unrelated to the European robin. American robins produce two to three broods per year and are among the earliest birds to sing in the morning chorus.
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.
