THE VESTIBULAR SYSTEM OF THE OWL,” K.E. Money and M.J. Correia, Comparative Biochemistry and Physiology Part A: Physiology, Volume 42, Issue 2, 1 June 1972, Pages 353–354, IN3–IN5, 355–358.

Abstract: Owls have a curious variability in the postrotatory head nystagmus following abrupt angular deceleration. Owls can exhibit a remarkable head stability during angular movement of the body about any axis passing through the skull. The vestibular apparatus in the owl is bigger than in man, and a prominent crista neglecta is present. The tectorial membrane, the cupula, and the otolithic membranes of the utricle, saccule and lagena are all “attached” to surfaces in addition to the surfaces bearing hair cells; these attachments are very substantial in the utricular otolithic membrane and in the cupula.
