Harrop (2008) stated that `Bulwer’s Petrel [Bulweria bulwerii] is a monotypic species of tropical waters, which breeds on islands of the eastern North Atlantic, Indian and Pacific Oceans between 10°S and 40°N (Onley & Scofield 2007). In the Atlantic it breeds on the Azores, Madeira, the Desertas, Great Salvage, the Canary Islands and Cape Verde. Most of those which breed in the Atlantic are believed to move south and west into the tropical Atlantic outside the breeding season’. In fact, it is quite a strong migrant, moving between 40°N and 40°S in the Atlantic (Bourne 1995), where it may also have bred on St Helena, at 16°S (Ashmole et al. 1999). It seems likely that most birds in the Indian Ocean are migrants from the Pacific, but an egg was found on Round Island, off Mauritius (20°S), in 1994 (Merton & Bell 2003). It breeds on the Marquesas at 9°S and bones have been found on Henderson Island at 24°S (Wragg 1995) in the central-south Pacific. This is hardly an entirely tropical distribution. In terms of the British claims, Bulwer’s Petrel is not a species that often occurs wrecked or on ships, so there are not many sources for imported specimens, especially in the days before refrigeration. Since John Gould seems to have been more interested in obtaining birds to figure than in where they came from, it is not surprising that there is little information about the supposed 1837 Yorkshire specimen, although it is not unusual for stray seabirds

British Birds – how it works
BB 2000 Ltd, the company that owns and publishes British Birds, is run by a board of directors, all of whom are volunteers. The company employs two full time staff – Roger Riddington is the journal’s editor while Hazel Jenner manages subscriptions and administration – and three part-time design/editorial staff.
The company is wholly owned by The British Birds Charitable Trust (BBCT, registered charity no. 1089422). Neither the company directors nor the trustees are paid for their services, providing their time and enthusiasm because they passionately believe in the value of BB. The Company is managed with a view to making a small profit which can be donated to the Trust to help fund its charitable work.
Over the past six years, this, combined with donations from other sources, has enabled the Trust to give almost £70,000 support to a variety of conservation and educational projects ranging from rat eradication on seabird islands to the study of cuckoo migration, as well as assisting young birders develop their interest.
A full list of projects is given here. The Trust is seeking to expand its charitable endeavours and would welcome donations from like-minded organisations and individuals.
