A flock of thousands of starlings flying above Sunbiggin Tarn in Cumbria.
The video, shot on January, shows the murmuration swirling in the sky at dusk.
The filmer writes:
''This starling roost is in a connifer plantation next to Tarn Sike nature reserve''
''This reserve in the Westmorland Dales Cumbria is a wonderful place to witness this spectacle.''
