Murmuration | Joel Walley Wildlife Photography
Murmuration. A large flock of Starling (Sturnus vulgaris) flying in to roost amongst the reeds at Leighton Moss RSPB, Lancashire. Migrant birds join those resident in the UK year round, to form huge flocks which swirl through the evening sky in almost perfect harmony. This spectacle peak in the autumn and winter months and large murmurations can contain hundreds of thousands of birds.
