Lesser kudu browser, the lesser kudu feeds on foliage from bushes and trees (shoots, twigs) and herbs. Despite seasonal and local variations, foliage from trees and shrubs constitute 60–80% of the diet throughout the year. The lesser kudu is mainly active at night and during the dawn, and seeks shelter in dense thickets just after the sunrise. The lesser kudu exhibits no territorial behaviour, and fights are rare. While females are gregarious, adult males prefer being solitary. No fixed breeding season is seen; births may occur at any time of the year. The lesser kudu inhabits dry, flat, and heavily forested regions.
