Question

Read the passage carefully and choose the correct answers from the options given below: Have you ever heard the sound of a hummingbird? They make a buzzing noise when they fly. They make this noise because they beat their wings so fast. They beat their wings up to 80 times a second. All that flapping makes a lot of noise. That's why we call them hummingbirds. Hummingbirds fly in a unique way. They move their wings so fast that they can hover. This means that they can stay at one spot in the middle of the air, like a helicopter. Sometimes, they fly or hover upside down. They are the only birds that fly backward. Hummingbirds are small. One type, called the bee hummingbird is the smallest bird in the world. Bee hummingbirds weigh less than a penny. They are just a little bit bigger than bees. Bee hummingbirds build tiny nests. They use cobwebs and bits of bark to make their homes. The female (bird) builds a cup-shape nest that is about 2.5 cm in diameter. This is big enough for their eggs though. Their eggs are smaller than peas. People have found these tiny nests on clothespins.Hummingbirds move fast. It takes lots of energy to move as fast as they do. This means that they need to eat a lot of food. Their favourite food is nectar, a sweet liquid inside the flowers. They drink nectar daily more than their own weight. They have to visit hundreds of flowers to get enough nectar to live.
