Activities and research interests

(Robert) Bob’s research qualifications are based in the interdisciplinary ‘systemic science’ that is well-suited to his lifelong interest and studies in ornithology (Doctor of Science, Doctor of Philosophy). Bob’s main interest is seabirds, in particular Procellariiformes (tubenoses), with a special interest in range, occurrence, identification and ageing. Such studies are an integral part of important research topics such as seabird conservation. In recent years, Bob has been increasingly involved with the FitzPatrick Institute of African Ornithology, exchanging knowledge and collaborating in studies, and his post as a Research Associate of the Institute cements these relations for future cooperation.

Bob has travelled the world’s oceans over the last 30 years, and over the last 15 years he has increasingly taken on the role of organising and leading expeditions to many of the most remote oceanic locations. Notably, at-sea expeditions have sailed the Melanesian islands, the Fijian islands, the Micronesian islands, the Marquesas Islands, the Pitcairn group, the Austral Islands, the Chatham Islands and Bounty Ridge, up the Humboldt Current, the Juan Fernandez archipelago, the remote Bering Sea (St Matthew’s Island and the Pribilofs). Bob has sailed the length of the Atlantic south to north four times. Less extreme pelagic trips include multiple trips out of Australia, New Zealand, Japan, South Korea, Mexico; and trips offshore Lima (Peru), Seychelles, Cape Town (South Africa), Bermuda, Svalbard, Cape Verde Islands, Canary Islands, Hatteras (USA).

Bob worked for several years as ship’s ornithologist on Antarctic expedition cruisers and was working as the ornithologist on MV Explorer when she hit an iceberg and sank in Antarctica – a stark reminder to all seabirder fanatics for the need to respect all aspects of the ocean.

In the course of these voyages and expeditions, Bob and teammates have made numerous contributions to knowledge about seabirds and Bob has published these observations in numerous well-respected refereed international journals (see publication list):

  • Co-rediscovered the New Zealand Storm-petrel at its breeding grounds off New Zealand (2003), the first step in its recovery and conservation, and found and identified the first (to date only) New Zealand Storm-petrel away from the breeding grounds, off Fiji, extending its range by some 2,500 km to the north (2017).
  • A first observer of the recently discovered New Caledonian Storm-petrel and contributions to understanding its taxonomy..
  • Found and identified three Murphy’s Petrels off Juan Fernández (2014), thereby considerably extending the species' range eastward and adding the species to the list of South American avifauna.
  • The second team to document with photographs Mascarene Petrel at sea off Reunion Island (2014), and in the process trained local conservationists working on saving the Mascarene Petrel in methods of attracting and studying these petrels at sea.
  • Documentation of a Chatham Island Petrel across the 180° Meridian from the Chatham archipelago (2016), and thus in the eastern hemisphere. This extends the known at-sea range to west of Chatham and close to South Island, New Zealand, indicating that it is in closer proximity to commercial fishing and other human activities than previously known.
  • Led the team that found and documented at sea the ‘near mythical’ dark-morph Herald Petrel off Ua Pou, Marquessas Islands.
  • Melanesia, sailed 3,000 km from Vanuatu to New Ireland (2017) adding knowledge to the identification and separation of Vanuatu Petrel / White-necked Petrel, range and distribution and first record of moult in Heinroth’s Shearwater, possible breeding location of Beck’s Petrel, new insights into the recently described Magnificent Petrel, and one of few sightings of probably an undescribed all-dark taxon of Pseudobulweria.

In addition, Bob has been involved in numerous first country records with the following being examples: Fea’s Petrel (Isles of Scilly, UK, 2001), Scopoli’s Shearwater (Isles of Scilly, UK, 2004), Madeiran Storm-petrel (Isles of Scilly, UK, 2007), Polynesian Storm-petrel (Australia, 2008), Cory’s Shearwater (United Arab Emirates, 2012), South Polar Skua (Madeira, 2013), Zino’s Petrel (Isles of Scilly, UK, 2019), De Filippi’s Petrel (Marquesas, 2020), White-faced Storm-petrel (Marquesas 2020). There are also numerous contributions to understanding and significantly rewriting the range of tubenose species.

Perhaps Bob’s most important contribution to seabird identification is through the highly acclaimed series ‘North Atlantic Seabirds Multimedia ID Guides’, with four titles published – Storm-petrels & Bulwer’s Petrel (2011, revised 2013), Pterodroma Petrels (2013), Albatrosses & Fulmarine Petrels (2016), Shearwaters, Jouanin’s & White-chinned Petrels (2020). These titles offer brand new insights into the identification and ageing of tubenose families, which is equally useful to researchers and to recreational seabirder fanatics.

Finally, and by no means least, Bob was the prime mover in establishing in 2006 and currently leads Scilly Pelagics, offering short-range pelagic trips from his home island St Mary’s, Isles of Scilly, off south-west England. The origin of Scilly Pelagics is in the mid-1990s though it is now a firm fixture on the UK birding calendar, offering trips mainly July–October, with the highly popular ‘Birder Special Pelagic 4-day weekends’ running throughout July and August. Bob occasionally leads seabird tours for tour companies, but only if the trip is utterly irresistible in terms of the tubenoses promised.
