In Memoriam: David E. Davis, 1913-1994

Abstract

vage, and the injection of microscopic beads of known but differing diameters into the cloaca of male birds and then searching for the spheres in lavages of females, Quay was able to document the degree of fidelity and copulatory performance of individual males and females in resident populations of many species. His extensive netting and banding activities during these years put him into contact with the Western Bird Banding Association. He became President of that organization (1987-1988) and editor of its contributions to the North American Bird Bander (1983-1986). Quay's demonstration of the great potential of cloacal lavage is an important contribution to ornithology. A connection between his research on the neuroendocrinology of the pineal complex and ornithology is not as apparent. However, in the year Bill Quay was born, William Rowan was launching his classic experiments with juncos and crows that demonstrated the importance of photoperiodism to the reproductive and migratory behavior of birds. One lifetime later, an army of pineal researchers is closing the gap between the photoperiodic world revealed by Rowan and the molecular/ cellular realm ruled by the pineal gland. Bill Quay played an important part in this endeavor.
