   • 1910, Anna Katharine Green, The House of the Whispering Pines‎:

     I knew the voice and cast one quick glance that way, in time to see Ella sinking affrightedly out of sight under the dismayed looks of father and mother; then, anxious to note whether the prisoner had recognised her, too, looked hastily back to find him standing quietly and unmoved, with his eyes on his counsel and his lips set in the stern line which was slowly changing his expression.

     Some circled in the air and occasionally swooped down towards the ground only to rocket up again affrightedly to the sky; for the tiger lay by its kill and resented the approach of any daring bird that aspired to share the feast.
