Gaelic name "Gobhan mara " means swallow of the sea

Great Skuas eat storm petrels. They live alongside where the petrels are breeding where they have a plentiful food supply. Rats and feral cats can also be a major problem for breeding birds

As with other seabirds, strong gales can sometimes blow many birds to shore, they are known as 'wrecks'. Nearly 7000 storm petrels were blown ashore in the UK in gales in November 1952.

The oldest recorded Leach's Storm-petrel was almost 30 years old.
