Red Deer are sometimes referred to as herd deer as compared with Roe Deer which are territorial. Both are genuine native animals. It's true that the red are often found in larger groups but experience on Blacka has demonstrated that they are quite as likely to wander round in small groups of two or three and even completely solitary.
This time of year hinds may be heavy with young and often you may see just one solitary animal. Three times this morning a single hind was seen. As to whether this was three different deer or one or two seen in different places, I pass.
Even now there are still a few signs of the winter coat clinging on as the seasonal red colouring takes over.
