The behaviour of red kangaroos (Megaleia rufa) on hot summer days.
To investigate the functional significance of the behaviour of large mammals in hot, arid conditions, field observations were made of the behaviour of red kangaroos. The behaviour of individual animals was recorded in detail during hot summer days and measurements  of the prevailing temperature and radiation environment were made. Changes in the postures adopted by animals during the day are described in relation to environmental conditions; and the occurrence of certain postures and behaviours at periods of greatest heat stress is reported.
