Reedbuck generally inhabits areas of grassland and floodplains, favoring reed-beds alongside permanent water.  A shrill whistle, often heard at night, is uttered when alarmed.  They are preyed upon by lion, wild dogs, hyena, leopard and cheetah.  On occasion they will lie flat when suspicious.  They run with a rocking motion and frequently stop and look back to the disturbance.  The tail is conspicuous when running.  They feed during early morning and late evening, lying up in tall grass during the day.  In the Okavango they favor small islands in the lagoons.  They occur singly, in pairs and in small groups of five or six.  Only the males have horns.
