Transcript
Bass Rock, off the east coast of Scotland, home to one of the largest colonies of gannets in the world. With a wingspan of nearly two meters, the northern gannet is the largest seabird in this part of the world.
150,000 gannets return to the rock each year after wintering on the west coast of Africa. Space on the small island is at a premium. The birds nest cheek by jowl. Every last bit of rock is taken and not everyone is happy with their neighbors. Mutual grooming is used to reinforce long-established pair bonds. Gannets pair for life and return to the same nest site year after year.
The seas around the island are rich in food and the gannets know exactly how to get at it. The young chicks are fed on regurgitated fish. Gannet chicks have a good chance of making it to adulthood. Both parents care for the single youngster, taking it in turns to go out fishing. They are dedicated parents and devoted partners. This young chick will not be ready to breed for another five years. But once it does, it may continue to do so for over 20.
