Abstract. This paper reports preliminary data on daily rhythmic fluctuations in skin and deep body temperatures of captive owls, and is a by-product of research aimed at the development of radio-telemetric techniques suitable for continuous, simultaneous monitoring of certain physiological and behavioral activities of unrestrained birds in the wild. The work was carried out at the University of Minnesota's Cedar Creek Natural History Area, located in Anoka County, during the period February-April 1971.

Keywords. Strigidae, radiotelemetry, physiology
