Current trail camera footage of a Pine Marten family at a site in Co. Tipperary. Pine Martens breed in summer, but implantation of the fertilised egg is delayed until winter, so kits are born in spring. By August, juveniles are 3-4 months old and forage with their mother.

Wild Fallow Deer doe & fawn at a site in Co. Tipperary. By August, a young fallow deer is still called a fawn, even though it is nearly the same size as its mother. Deer are always nervous – in the video they give little jumps when they think they hear something on the higher bank above the river.
