Astonishing amateur footage has captured a starling murmuration in Suffolk.
The video, filmed by birdwatcher Karen McCoy, shows the spectacle at RSPB Minsmere this weekend.
With Autumn comes an increase in the spectacle - with experts believing that the birds fly close together to keep warm and safe from predators.
It is also believed that the birds exchange information during the aerial displays, such as good areas to feed.
McCoy, 50, a business analyst from Sonning near Reading, told ITV News she believed around 10,000 starlings were taking part in the display - though this can reach 100,000 in some parts of the UK as the weeks go on.
The large numbers didn't stop a peregrine falcon diving into the mass and plucking out one of the small birds at one stage.
