'Ring Angels' refer to the strange phenomenon discovered in 1958. Scientists were perplexed at the strange lights appearing on their radar screens. The light resembled ripples on a pond, with rings of light appearing for 2 and a half to 6 minutes before completely disappearing! There were many sightings of 'Ring Angels' around England but it wasn't until a year later that the strange occurrence was understood. Scientists realized that what they were seeing each morning, were Starlings leaving their roosting grounds, in waves separated by 3 minute intervals!
