Abstract
Field observations were made over 3 years at several farmland areas in southern Michigan. Most observations of captive birds were made at the Mayer Pheasant Farm in Brighton, Michigan; other captive pheasants were kept at the Rose Lake Wildlife Experimental Research Station and at Michigan State University in outdoor and indoor pens, and, in the case of small chicks, in brooder pens. Calls were recorded at 71/? inches per second on a portable Uher 4000 Report-L tape recorder equipped with a Uher M514 microphone, which was often used with a 24-inch parabola. Spectrographic analysis of vocalizations was made on a Kay Electric 661A Sonograph on wide band analysis. Recorded calls were played back to pheasants on a portable Ampli-Vox S-200 Diplomat amplifier and loudspeaker unit To stimulate crowing in one male, one dose of 100 mg testosterone propionate U.S.P., suspended in corn oil, was injected intramuscularly into its leg.
