Thousands of people will take part in the RSPB's annual Big Garden Birdwatch at the weekend, helping to gather information about how birds in Scotland are faring this winter.

Among them will be the residents of a Scottish nursing home, near Dumfries, where staff believe regular bird watching sessions can help us stay mentally alert in old age.

BBC Scotland's environment correspondent David Miller reports.
