Question

Birds are the only animals with feathers, although some other animals, such as insects and bats, also have wings．Nearly all birds can fly, and even flightless birds, such as ostriches （鸵鸟）, penguins, evolved from flying ancestors．

Birds are found worldwide in many habitats．They can fly over some of the highest mountains on earth as well as both of the earth’s poles, dive through water to depths of more than 250m, and occupy habitats with the most extreme climates on the planet, including arctic tundra （冻土地带） and the Sahara Desert．Certain kinds of seabirds are commonly seen over the open ocean thousands of kilometers from the nearest land, but all birds must come ashore to raise their young．

Highly developed animals, birds are sensitive and responsive, colorful and graceful, with habits that excite interest and inquiry．People have long been fascinated by birds, in part because birds are found in the same habitats in which humans live．And like people, most species of birds are active during daylight hours．Humans find inspiration in birds’ capacity for flight and in their musical calls．Humans also find birds useful---their flesh and eggs for food, their feathers for warmth, and their companionship．Perhaps a key basis for our friendliness with birds is the similarity of our sensory worlds: Both birds and humans rely more heavily on hearing and color vision than on smell．Birds are useful indicators of the quality of the environment, because the health of bird populations mirrors the health of our environment．The rapid decline in birds populations and the accelerating extinction rates of birds in the world’s forests, grassland, wetlands, and islands are therefore reasons for great concern．
