Chapter 1 Animals That Fly Many animals fly because it helps them to stay safe, and they can move around fast to find food. For example, bees fly to collect nectar from flowers. Then they use the nectar to make honey. Some animals fly to hunt other animals, so that they can eat them. For example, owls fly to hunt smaller animals, like mice. Some animals fly to stay safe from other animals that want to eat them. For example, small birds fly to escape from cats and dogs. Many birds make their homes in tall trees, where they are safe. Some birds, like storks, make their nests in high places, like the top of tall poles or buildings. Discover! Some storks make very big nests. The nests can be 2 meters across.

第一章会飞的动物许多动物会飞是因为它能帮助它们保持安全，而且它们能快速移动以寻找食物。 例如，蜜蜂飞着从花中采集花蜜。 然后它们用花蜜酿蜂蜜。 有些动物飞着去捕食其他动物，这样它们就可以吃掉它们。 例如，猫头鹰飞着捕食小动物，比如老鼠。 有些动物飞行是为了躲避其他想要吃掉它们的动物。 例如，小鸟飞是为了躲避猫和狗。 许多鸟在高大的树上筑巢，在那里它们是安全的。 有些鸟，比如鹳，在高处筑巢，比如高杆或建筑物的顶部。 发现!有些鹳的巢很大。 鸟巢的直径可达2米。

Chapter 2 Wings and Feathers Birds have many small feathers on their body. The feathers keep birds warm and dry. Most birds also have longer feathers on their wings and tail. These are called flight feathers because they help birds to fly. Birds have very thin bones with air spaces inside. The bones are very light, so it's easy for birds to fly. Some birds have very big wings. The Andean condor is one of the biggest flying birds in the world. It can have a wingspan of 3 meters. Other flying birds are small, with short wings. Some hummingbirds have a wingspan of only 6 centimeters. Discover! The biggest flying bird was the Giant Teratorn. It lived about six million years ago and it had a wingspan of up to 7 meters!

鸟的身上长着许多细小的羽毛。 羽毛使鸟类保持温暖和干燥。 大多数鸟类的翅膀和尾巴上的羽毛也更长。 这些被称为飞行羽毛，因为它们帮助鸟类飞行。 鸟类的骨头很薄，里面有空隙。 骨头很轻，所以鸟类很容易飞起来。 有些鸟有很大的翅膀。 安第斯秃鹰是世界上最大的飞禽之一。 它的翼展可以达到3米。 其他飞禽体型小，翅膀短。 有些蜂鸟的翼展只有6厘米。 发现!最大的飞禽是巨龟。 它生活在大约600万年前，翼展可达7米!

Chapter 3 Amazing Fliers Most birds can fly, and some of them are amazing fliers! The fastest bird in the world is the peregrine falcon. When it's diving straight down, a peregrine falcon can fly at more than 200 kilometers per hour! Swallows are really amazing fliers. They hunt insects in the air, so they need to dive and turn very fast. It's fun to watch swallows in the evening, when there are lots of insects flying around. Some birds make amazing journeys to find food, or to travel to a place to have their babies. Bar-tailed godwits fly all the way from New Zealand to Alaska that's about 16,500 kilometers! The journey only takes about one week, with a short stop in China to rest and eat. Discover! Swifts are small birds that spend most of the time flying. They can even sleep in the air!

大多数鸟都会飞，其中一些是惊人的飞行者!世界上飞得最快的鸟是游隼。 当它直接俯冲时，游隼的飞行速度可以超过每小时200公里!燕子真是神奇的飞行者。 它们在空中捕食昆虫，所以它们需要俯冲和快速转弯。 晚上看燕子很有趣，因为有很多昆虫飞来飞去。 有些鸟会进行奇妙的旅行去寻找食物，或者去一个地方生孩子。 斑尾鹬从新西兰一直飞到阿拉斯加，这大约是16500公里!这次旅行只需要大约一周的时间，在中国短暂停留，休息和吃饭。 发现!雨燕是一种大部分时间都在飞行的小鸟。 它们甚至可以在空中睡觉!
