What beautiful things birds are! Can you think of any other creatures that are quite so beautiful? I know you will say "Butterflies," and perhaps it _is_ a race between the birds and the butterflies, but I think the birds win it even here in England. Just think of the Kingfisher, that bird that is like a little live chip of the blue sky, flying about all by itself, and doing just what it likes. The Sky-blue Butterfly is like that too, I know, but then it is a much smaller chip, and does not shine in the sun in such a wonderful way as the Kingfisher does. Neither, I think, does the Peacock-Butterfly, or the Red Admiral, or the Painted Lady, or the Greater or Lesser Tortoise-shell; and, besides, they none of them go so fast. Yes, all those butterflies are beautiful, very, very beautiful. But now, supposing they were all flying about in a field that a river was winding through, and, supposing you were sitting there too, amongst the daisies and buttercups in the bright summer sunshine, and looking at them, and supposing all at once there was a little dancing dot of light far away down the river, and that it came gleaming and gleaming along, getting nearer and nearer and keeping just in the middle all the time, till it passed you like a sapphire sunbeam, like a star upon a bird's wings, then I am sure you would look and look at it all the time it was coming, and look and look after it all the time it was going away, and when at last it was quite gone you would sit wondering, forgetting about the butterflies, and thinking only of that star-bird, that little jewelly gem. But, perhaps, if you were to see a _Purple Emperor_ sweeping along--ah, _he_ is a _very_ magnificent butterfly, is the purple emperor. You can tell that from his name, but whether he is _quite_ so magnificent as a star-bird (for that is what we will call the Kingfisher)--well, it is not so easy to decide. The birds and the butterflies are both beautiful, there is no doubt about that, only this little book is about beautiful birds, and perhaps afterwards there will be another one about beautiful butterflies. That will be quite fair to both.
