From attics in County Armagh to gardens in Lisburn and a busy, multi-lane road close to Belfast city centre, pine martens - one of Northern Ireland's rarest native mammals - have been turning up in some unusual places.

At one stage almost extinct in Northern Ireland, the pine marten clung on in the woodlands of County Fermanagh, the Glens of Antrim and the Mournes.

Now they're found in all six counties and increasingly crossing paths with humans.
