Now, like all good parents, Mis and his mate were a bit particular about what sort of neighborhood they should choose for their home; for the bringing up of a family, even if it is a small one, is most important. A peaceful place and a sunny exposure they must have; there must be good hunting near at hand; and one more thing, too, was necessary. Now, the house-lot they finally decided upon met all four of these needs, though it sounds like a joke to tell you where it was. But then, when a clown goes merrily forth to find him a home, we must not be surprised if he is funny about it. It was where the sun could shine upon it; though how Mis and his mate knew that, all on a dull, dark afternoon, I'm sure I can't tell. Maybe because there wasn't a tree in sight. And as for peace, it was as undisturbed as a deserted island. It was, in fact, a sort of island in a sea of air, and at certain times of the day and night there was game enough in this sea to satisfy even such hunters as they. Perhaps they chuckled cosily together when they decided to take their peace and sunshine on the flat roof of a very high building in a very large city. Their house-lot was covered with pebbles, and it suited them exactly. So well that they moved in, just as it was. Yes, those two ridiculous birds set up housekeeping without any house. Mother Nomer just settled herself on the bare pebbles in a satisfied way, and that was all there was to it. Not a stick or a wisp of hay or a feather to mark the place! And as she sat there quietly, a queer thing happened. She disappeared from sight. As long as she didn't move, she couldn't be seen. Her dappled feathers didn't look like a bird. They looked like the light and dark of the pebbles of the flat roof. Ah, so _that_ was the one thing more that was necessary for her home, besides sunshine and peace and good hunting. It must be where she could sit and not show; where she could hide by just looking like what was near her, like a sand-colored grasshopper on the sand in the sun,[2] or a walking-stick on a twig,[2] or a butterfly on the bark of a tree.[2]
