RSPB Scotland is looking for volunteers in and around Oban and Fort William who could make a big difference for nature just by looking after a box of pin badges.
RSPB pin badges were launched in the 1990s and there are now more than 200 designs available, from garden birds to basking sharks, ladybirds and even Highland cows.
Boxes of badges are sited at more than 7,000 outlets throughout the UK, with avid collectors keen to get hold of any new designs.
