The snowy owl (雪鹗) is a white-colored owl with many unique characteristics. This bird bears a pure white appearance (only the male), with a rounded head, and black bill. While the male is actually a pure white individual, the female and young ones have a darker appearance with dusky spots. The female owl never attains complete whiteness in her lifetime. As young owls get older, they get whiter, losing their heavy stripes (条纹) and dark spots. This bird is between 18 to 20 inches long. Its Wingspan is 49 to 59 inches. It weighs between 3.5 to 6.5 pounds.
The snowy owl lives in the regions of Greenland, Iceland, Canada, and the northern parts of USA. Carolus Linnaeus was the first person to classify this bird. Apart from being the heaviest owl in North America, it is also the official bird of Quebec. It is known by other names such as “the Arctic Owl” or “the Great White Owl”. The reason for this bird’s adaptation to the cold temperatures of the Arctic Circle is its splendidly beautiful, white, and thick feathers. These feathers help it to survive the extreme cold and develop a perfect camouflage (伪装) in the “white” of its Arctic habitat.
The snowy owl is a very patient hunter, and it can sit in one place for hours. Gifted with great hearing and keen eyesight, it is known to be an efficient and clever hunter. It is not difficult for it to track down its prey, which might be barely visible under thick plants or snow cover. Before soaring off in pursuit, the bird waits patiently and identifies its potential prey. Once the prey comes within the proper range, it lays its attack with its sharp-hooked claws. It hunts both during the day and at night.

Music has always been associated with exercising. Most of us listen to our favorite music while jogging in the park or while working out in the gym, but we never think of it as more than just an accompaniment to our exercisc routine. But recent scientific research has thrown light on the fact that using the “right” music while exercising can do you a whole lot of good: from creating a feeling of positivity to calming any anxious feelings.
Research on the effects of music during exercise has been done for years. In 1911，an American researcher, Leonard Ayres, found that cyclists pedaled faster while listening to music than they did in silence.
This happens because listening to music can drown out our brain’s cries of fatigue. As our body realizes we’re tired and wants to stop exercising, it sends signals to the brain to stop for a break. Listening to music competes for our brain’s attention, and can help us to overcome those signals of fatigue, though this is mostly beneficial for low-and moderate-intensity exercise. During high-intensity exercise, music isn’t as powerful as pulling our brain’s attention away from the pain of the workout.
Not only can we manage to exercise longer and harder when we listen to music, but it can actually help us to use our energy more efficiently. A 2015 study showed that cyclists who listened to music required 7% less oxygen to do the same work as those who cycled in silence. So in the same way that exercising makes us happier, it’s not surprising that music adds significantly to our work-out success.
