At "h" I found more blood and at "j" I got a new thrill, for there, plain enough on each side of the Rabbit track, were finger-like marks, and the truth dawned on me that these were the prints of great wings. The Rabbit was fleeing from an eagle, a hawk, or an owl. Some twenty yards farther "k" I found in the snow the remains of the luckless Rabbit partly devoured. Then I knew that the eagle had not done it, for he would have taken the Rabbit's body away, not eaten him up there. So it must have been a hawk or an owl. I looked for something to tell me which, and I got it. Right by the Rabbit's remains was the large twin-toed track (l) that told me that an owl had been there, and that therefore he was the criminal. Had it been a hawk the mark would have been as shown in the left lower corner, three toes forward and one back, whereas the owl usually sets his foot with two toes forward and two backward, as in the sketch. This, then, I felt sure was the work of an owl. But which owl? There were two, maybe three kinds in that valley. I wished to know exactly and, looking for further evidence, I found on a sapling near by a big soft, downy, owlish feather (m) with three brown bars across it; which told me plainly that a Barred Owl or Hoot Owl had been there recently, and that he was almost certainly the killer of the Cottontail. This may sound like a story of Sherlock Holmes among the animals--a flimsy tale of circumstantial evidence. But while I was making my notes, what should come flying through the woods but the Owl himself, back to make another meal, no doubt. He alighted on a branch just above my head, barely ten feet up, and there gave me the best of proof, next to eye witness of the deed, that all I had gathered from the tracks and signs in the snow was quite true. I had no camera in those days, but had my sketch book, and as he sat, I made a drawing which hangs to-day among my pictures that are beyond price. Here, then, is a chapter of wild life which no man saw, which man could not have seen, for the presence of a man would have prevented it. And yet we know it was true, for it was written by the Rabbit himself. If you have the seeing eye, you will be able to read many strange and thrilling happenings written for you thus in the snow, the mud, and even the sand and the dust. TALE 57 The Singing Hawk Listen, Guide and young folk, I want to add another bird to your list to-day; another secret of the woods to your learning. I want you to know the Singing Hawk. Our nature writers nearly always make their hawks scream, but I want you to know a wonderful Hawk, right in your own woods, that really and truly sings, and loves to do it.
