Winter has winged its way across Europe and starlings once again created their dazzling displays in the skies above Gretna Green in Scotland.
This bi-annual "murmuration" - in February and November - occurs when the mainland Europe becomes too cold for the birds, and the starlings flock above warmer Britain, sometimes in hundreds of thousands, before flying down and roosting in the trees.

Like a living cloud, the birds gather in this way both to keep warm as a form of protection from predators, according to the RSPB.
The best time to see the incredible displays is just before dusk, when the starlings ready themselves for roosting.
