The daily and hourly movements of eight male desert-dwelling elephants of various ages (12-45 years old) were determined hourly by global positioning system (GPS)/telemetry collars during the wet, cold dry and hot dry seasons of 2006 in northwest Namibia. The average daily movement in the wet season was greater than that observed during either the cold dry or the hot dry seasons. A similar difference was also observed for the movement rates, with the highest average rate of hourly movement recorded during the wet season. The diurnal movements (both distance and rate) were greater than those in the nocturnal hours during the wet season, whilst during the cold dry and hot dry season the reverse was true. The daily cycle of movement also changed seasonally, with greatest movement rates observed during the wet season between 11.00-20.00 hours, during the cold dry season between 14.00-21.00 hours; and between 04.00-11.00 hours during the hot dry season. Periods of decreased movement rates were observed between 09.00-10.00 and 02.00-03.00 hours in the wet season; 03.00-06.00 and 11.00-13.00 hours in the cold dry season; and 01.00-03.00 and 12.00-14.00 hours during the hot dry season.
