Abstract

A FACTOR ANALYSIS OF SEASONAL, BEHAVIORAL, HORMONAL AND BODY WEIGHT CHANGES IN ADULT MALE BARHEADED GEESE, ANSER INDICUS by JOHN P. DITTAMI and HEINZ-ULLRICH REYER (Max-Planck-Institut für Verhaltensphysiologie, Seewiesen and Andechs, F.R.G.) (With 3 Figures) (Acc. 28-XII-1983) Correlations between the circulating levels of hormones and the frequen- cies of behavior have been used to study behavioral hormonal inter- actions by a number of authors with both positive and negative results (BALTHAZART, 1976; BALTHAZART & HENDRICK, 1976; GORMAN, 1977; H?,RDING & FEDER, 1976; LESHNER, 1978, for a review; PRÖVE, 1978; TSUTSUI & ISHII, 1981). One of the most important aspects of these experiments is that they produce a framework within which many other experiments manipulating the peripheral levels of hormones and behavior can be interpreted.
