Population justification: On Gough, Cuthbert in litt. (2001) estimated 1.8 million breeding pairs, suggesting a world population of around 5 million birds.
Trend justification: R. Wanless in litt. (2007) has commented that population models using data (except breeding success) from Bermuda Petrel Pterodroma cahow suggest the populaiton is declining at a rate of 1.3% per annum.
