Life history theory predicts that the amount of time allocated to vital behaviours will change with life history stage, resulting in trade-offs between competing behaviours. Moreover, a range of environmental factors can also affect activity budgets. We studied diurnal time allocation by migratory plains zebras (Equus quagga) in the Serengeti ecosystem, Tanzania, and investigated the effect of life history stage, social environment, habitat structure, and day time on time allocation to five behavioural categories (grazing, resting, vigilance, movement, other). We expected (1) increased vulnerability to predation and impeded predator detection to increase vigilance and decrease resting and grazing; (2) energetically costly life stages to increase grazing and decrease resting; and (3) increasing age in young to result in increased vigilance and grazing and decreased resting. Our findings revealed that in young zebras, resting decreased and grazing increased from the youngest to the oldest age class. Band stallions spent more time grazing and less time resting and moving than bachelors. Lactating mares devoted more time to grazing but less to resting and vigilance than other mares. Mares spent most time vigilant in the last third and stallions in the first third of the day. Adult zebras moved more, and mares were more vigilant in the woodland boundary than on short grass plains. Taken together, our study identifies intrinsic and extrinsic factors shaping time allocation decisions and trade-offs between competing behaviours in plains zebra.</dcterms:abstract> </rdf:Description> </rdf:RDF>
