was of the same gray as the lower lid, and thick. (This needs further confirmation before positive statement. At the moment I do not recall having seen the nictitating membrane of these birds except when they are "sunfitting"; then it is brought into frequent action. (See below) I checked up on this about 2:40 by holding my hands in reading position and Brownie very accommodatingly jumped up and took the place of a book. She did not wink with her upper lid, but the nictitating membrane flickered across her cornea frequently, but so rapidly that it was like the shutter of a camera. A minute or two after Greenie was on my hand by my side and the same thing was noted in him. Comparative eye color. There is still the same difference in eye color between these birds.
