Gannets gathered at Bempton Cliffs in Yorkshire, as more than 250,000 seabirds flock there to mate and raise their young. From April to August, the cliffs come alive with nest-building adults and young chicks. The nature reserve, run by the RSPB, is best known for its breeding seabirds, including northern gannet, Atlantic puffin, razorbill, common guillemot, black-legged kittiwake and fulmar.
