The Bempton Cliffs reserve, on the spectacular Yorkshire coast, is home to one of the UK’s top wildlife spectacles. Around half a million seabirds gather here between March and October to raise a family on towering chalk cliffs overlooking the North Sea.
With special thanks to George Stoyle who made this film for the RSPB Bempton Cliffs Reserve.
