Diurnal activity patterns of Burchell's zebra (Equus quagga, Gray 1824) in Yabello Wildlife Sanctuary, Southern Ethiopia

A b s t r a c t K e y w o r d s A study on the diurnal activity pattern of Burchell s zebra (Equus quagga, Gray 1824) was carried out in the Yabello Wildlife Sanctuary, Southern Ethiopia during October 2009 to March 2010 including wet and dry seasons. Scan sampling methods were used to collect the data peaks in daily activity occurred in early morning, mid day and late afternoon. Data on activity time budget were analyzed by assessing time allocated for different activities at different hours of the day as well as different seasons. Differences in seasonal and hourly time budget were tested using one way ANOVA, followed by Tukey multiple comparison test. The time devoted to grazing was peaked during the dry season and gradually decreased during the wet season. There was a significant difference in the amount of hours devoted to different activities (t =76.4=, p< 0.05). The proportions of time budget varied between two seasons. Grazing accounted for more than 55.5%. Peak activities were observed early morning and late afternoon hours with resting peak durin g the mid-day.
