“Yes, that is often the case, as I am glad to find that you remember, but not with the Screech Owl, the most common of American Owls, and one that is known under many names—Mottled Owl, Gray Owl, and Red Owl.
SCREECH OWL
“There may be some gray birds and some red ones in the same brood, but this does not depend upon sex, season, or age. The strange difference is called by a long name, ‘dichromatism’ or two-colour phase, and this is one of the things for which the Wise Men can give no positive reason; so it is another question like those about the flight and travels of the birds for one of you to find out in future.
“Bring the box up to the orchard, Tommy, and, after we have seen the gray Screech Owls, you can open the door and put the box in the tree and see what will happen.”
Before they reached the gate of Birdland, they heard a commotion inside; Jays were screaming in a great state of rage and alarm, and, as they drew nearer, another sound blended with the screaming, a hissing sound like “shay—shay—shay,” and the snapping of beaks.
“The Jays have found the Owls out, and they’re hopping mad,” said Jacob, who was standing in the shelter of a tree-trunk, enjoying the scene. “The Jays daren’t really touch the Owls, only jeer, and the Owls only snap their beaks and hiss in return because they don’t like to fly out in bright light; all you get back by the fence and watch out.”
The children did as Jacob suggested and Tommy put his box on top of the wall and, at a signal from Gray Lady, unfastened the slats. At first the little Red Owl stretched his neck and snapped his beak; then, as he heard the voices of the Jays, he backed into the corner of the box and drew himself up thin and long, so that he did not look like the same bird that had been so plump and fluffy a few seconds before.
“That’s just the way he did this morning when I found him in the pigeon-house,” said Tommy; “in the dark he didn’t look a bit like a bird, but more like a corn-cob on end.
“There! look there, Gray Lady.” And Tommy pointed at a tree behind that in which the five Owls were roosting. “There is another Owl all by itself that the Jays haven’t found out, and it’s all drawn up thin just like my red one.” And, following the direction of his finger, the Owl was plainly to be seen, but so rigid and motionless that it might have been a moss-covered branch stump.
