Monkey Drive-Though At Blair Drummond
Scotland's only monkey drive-through has opened at Blair Drummond Safari Park.
Visitors can now get up close and personal with a troop of 30 Barbary macaques at the park near Stirling.
Nature lovers have been warned to keep their windows, doors and roof boxes firmly shut as they drive through the five-acre reserve.
Park manager Gary Gilmour said: "The macaques are very inquisitive and will investigate novel items.
"For those not brave enough to take a car through, we have a bypass in place and you can see the macaques through the viewing windows of their building.''
The monkeys are known as the the Middle Hill Troop having previously lived between the top of Gibraltar rock and the town, where their expanding population had begun to cause problems for local residents.
The troop arrived at the park in October last year as an alternative to lethal control.
Barbary macaques are listed as endangered and the monkeys are being cared for at the park as part of a breeding group, with young and newborn already on view.
Head keeper Craig Holmes said: "The macaques have settled in really well, when visitors drive round they'll see the macaques spread throughout the reserve.
"We keep the reserve somewhat overgrown to encourage natural behaviour and enrich the life of our macaques.
"We have researchers studying the behaviour of our troop so we can compare them to their wild counterparts and also ensure the welfare of our troop is monitored and improving all the time.''
Sturgeon says Trump is on the "wrong side" of the debate.
The boys were found inside the Sainsbury's store at 2am on Tuesday.
The incident, which happened at Ibrox station, was reported to British Transport Police before 8pm on Saturday.
