Energetics and Water Regulation in the Cowbird (Molothrus ater obscurus)
University of Chicago: Chicago, 1970. Soft cover. A specialized late twentieth-century zoological offprint examining energy balance and water regulation in the brown-headed cowbird, presenting physiological data derived from controlled experimental observation.
Issued in 1970 and reprinted from Physiological Zoology, this paper reflects the period’s emphasis on quantitative biological research, contributing to broader understanding of avian metabolism and environmental adaptation.
Stapled softcover offprint, approximately 9.25 inches tall. Pages 270–287, including charts, tables, and cited references. Reprinted from Physiological Zoology, Vol. 43, No. 4, October 1970. No flaws or blemishes, minimal shelf handling, light even toning, staples secure, text and charts clean and legible.
A focused example of academic offprint culture, produced for limited professional circulation rather than commercial distribution. Such reprints were typically retained by researchers or institutions and discarded over time, making clean surviving copies increasingly scarce outside university libraries.
Subjects: Ornithology, Avian physiology, Cowbirds, Metabolic regulation, Water balance, Physiological Zoology, Twentieth-century biological research, Scientific ephemera, Academic offprints, Natural history.
