@rob257 Thanks Rob, This bird is a Starling, here they are as a group or murmoration as it's know https://www.youtube.com/watch?v=QOGCSBh3kmM. I used the colour Efex pro and sharpener pro from from the free Nik Efex collection.
I watched your you tube link of the murmuratiom. We had a much smaller display nearby but the most amazing thing too was when they all settled into just one tree, they must have been absolutely crammed in together.
