A Highland glen has seen its first visit in several years by members of the John Muir Trust, with the volunteers repairing bird habitats after December's severe snow.
The group visited Glen Tanar in the Cairngorms National Park, clearing away fallen wood during the visit, which saw them have to contend with frozen ground despite temperatures of 7C.
Good walking boots
and winter jackets
may be needed by those visiting the national park at this time of year, not least for those climbing its mountains in what are often arctic conditions.
Head ranger for the glen Eric Baird said he was glad to see the volunteers back, commenting: "After a break of a few years I welcome back the John Muir Trust volunteers whose enthusiasm and energy really makes a big difference to the natural environment of the estate."
Glen Tanar lies in the Royal Deeside part of the national park and those walking in the valley can access Mount Keen, which is 3,081 ft high and the easternmost of Scotland's Munros.
