Other birds, like the reed-warbler, build in reeds; this seems a very safe plan. Here you see several tall green reeds growing out of the water, and about a foot above the water the bird has made a clever nest, twisting bits of roots and grass together, and lacing them in with the reeds, which are strong enough to hold such a dainty thing. So the little nest swings and sways with the wind over the water, and the reed-warbler is safe from cats, at all events; but one imagines the young birds must sometimes tumble out and get drowned before they can fly. A very odd bird is quite near this, and that is the butcher bird. He really is a butcher--that is to say, he kills tiny animals and even other little birds, and keeps them in a larder for use. For this purpose he chooses a bush with thorns, perhaps a hawthorn, and then when he catches any small creature he sticks it on the thorns and leaves it there spiked until it is wanted. Look at this one's larder. He has a wretched little dead sparrow hanging by its neck from a big thorn, and two or three bumble-bees spiked too. We can imagine the mamma saying to the little ones: 'No, dears, you mustn't have any sparrow to-night just before you go to bed; it would give you indigestion and make you dream. Papa will have some of that for his supper, but if you'll be good children I'll give you each a bit of bumble-bee.' The mother bird is talking to a young one who has got out of its nest. They are fat, strong little birds, as they should be with such food. After this we come to bigger birds--ducks and puffins. Puffins have beaks like poll parrots, and are about the size of a rook; they have neat white shirt-fronts, and their beaks are red and yellow and blue, but they have silly faces, as if they thought of nothing but their own fine clothes. They live near water on cliffs, and sometimes use an old rabbit burrow for a nest, in which they lay one pure white egg, and one only. When the young one is hatched the parent birds feed it on tiny fish and minnows. You can see here the puffin bringing up a minnow in his beak for supper.
