Response of wildebeest to direct solar radiation and wind was measured at hourly intervals from sunrise to sunset, during cold and hot seasons in the Etosha National Park. The two-dimensional data were statistically analysed by a computer programme package (DIRECT). The findings indicate that wildebeest orientate significantIy in relation to the sun when its attitude is low (< 45) and that during the midday sector wind influences body position.
