It’s starling murmuration season again (this runs from late autumn through the winter). The occurs as the local populations of starlings are boosted by their European cousins arriving to escape the harsh Scandinavian winter. A starling murmuration is an amazing sight, with huge flocks forning into an amazing acrobatic mass before roosting.
There have been huge gatherings of starlings over the lakes of the Cotswold Water Park over the last few days, with flocks in excess of 50,000 being reported. Amazing!
This is a great article giving tips about how to photograph their antics! http://www.theguardian.com/travel/gallery/2014/dec/09/starling-murmurations-how-to-photograph-in-pictures
