tly attached to him, thoughbeyond a friendly indifference he did not manifest any affection in return.There was something eerie about him, however, so that when a friend discover© 1his presence between the clock and a vase upon our mantlepiece she wasfrightened, and when he began to wave his head to and fro, shifting his weightfrom one foot to another and changing the focus of his yellow eyes, she fled.This ability to increase or decrease the size of the pupils, regardless of a differ-ence in light, is a peculiarity that I have noted in three species of Owls, theScreech Owl, the Barred Owl, and the Great Horned Owl. The ability seemsto be voluntary, for I have seen the pupils of all three species change in sizewhen food was offered for close-range inspection, and 1 have observed, in thecase of the Screech Owl and the Great Horned Owl, the pupil of one eyechange without relation to the pupil of the other; this difference, when suddenlyeffected, gives the Owl a very uncanny appearance.
