About These Birds
红尾鵟
The red-tailed hawk is the most widespread and common hawk in North America. Its screaming cry is so iconic that it is often dubbed over bald eagle footage in films and television. These adaptable raptors thrive in human-altered landscapes and are a familiar sight perched along highways.
鹭鹰
The secretary bird is the only raptor that hunts primarily on foot, striding through grasslands on crane-like legs up to 1.2 meters tall. Its name may derive from the crest feathers resembling quill pens tucked behind a secretary's ear. The species is classified as Endangered due to habitat loss and decline across much of its range.
