Busy indeed was Mis in the twilights that followed the hatching of his children; and, though he was as much in the air as ever, it was not the fun of frolic and clownish tricks that kept him there. For, besides his own keen appetite, he had now the hunger of the twins to spur him on. Such a hunter as he was in those days! Why, he caught a thousand mosquitos on one trip; and meeting a swarm of flying ants, thought nothing at all of gobbling up five hundred before he stopped. Countless flies went down his throat. And when the big, brown bumping beetles, with hard, shiny wing-covers on their backs and soft, fuzzy velvet underneath, flew out at dusk, twenty or thirty of them, as likely as not, would make a luncheon for Mis the clown. For he was lean and hungry, and he ate and ate and ate; but he never grew fat. He hunted zigzag through the twilight of the evening and the twilight of the dawn. When the nights were bright and game was plenty, he hunted zigzag through the moonlight. When the day was dull and insects were on the wing, he hunted, though it was high noon. And many a midnight rambler going home from the theatre looked up, wondering what made the darting shadows, and saw Mis and his fellows dashing busily above where the night-insects were hovering about the electric lights of the city streets. He hunted long and he hunted well; but so keen was his appetite and so huge the hunger of his twins, that it took the mother, too, to keep the meals provided in the Nomer home. I think they were never unhappy about it, for there is a certain satisfaction in doing well what we can do; and there is no doubt that these birds were made to be hunters. Mis and his kind swept the air, of course, because they and their young were hungry; but the game they caught, had it gone free to lay its myriad eggs, would have cost many a farmer a fortune in sprays to save his crops, and would have added untold discomfort to dwellers in country and city alike. Although Mis, under his feathers, was much smaller than one would think to look at him, there were several large things about him besides his appetite. His mouth was almost huge, and reached way around to the sides of his head under his eyes. It opened up more like the mouth of a frog or a toad than like that of most birds. When he hunted he kept it yawning wide open, so that it made a trap for many an unlucky insect that flew straight in, without ever knowing what happened to it when it disappeared down the great hollow throat, into a stomach so enormous that it hardly seems possible that a bird less than twice the size of Mis could own it.
