Breeding dispersal, defined as the net movement between successive breeding sites, remains a poorly understood and seldom reported phenomenon in mammals, despite its importance for population dynamics and genetics. The roe deer can be spotted throughout Scotland and it’s always a lovely sight! The rut will vary from species to species, though the classic example is deer butting heads in a test of strength.
