Several swallows live in each nest. You see a head poking out of the nest, then a pair of scissor wings as a swallow flies off, then immediately another pokes its head out. Six or seven swallows live in each nest; these are fairly large families.
每一個燕窩住了不少燕子，你看到一個頭鑽出來，一剪翅，一隻燕子飛遠了，接著另一隻鑽出頭來，一個窩總住著六七隻燕，是不小的家庭了。
