Celestial Canaries March 14Th – March 28Th 2019 Celestial Canaries th th March 14 – March 28 2019 DAY 1 - Thursday 14th March 2019 Sea State: 4 Sky: Overcast, showers Temperature: MAX 11°C Saga Sapphire Sets Sail Dover 18:00 The ORCA team (top to bottom): Hannah Ramsey- Smith (Team Leader), Maria Freel, Kathleen Neri and Shenaz Khimji (Wildlife Officer) The ORCA team very much enjoyed spending time with guests on board the Saga Sapphire during the Celestial Canaries Cruise in spring 2019. We especially appreciated hearing about your wildlife encounters whilst simultaneously spotting and identifying cetaceans and birds with you out on deck. We are also thankful to Saga Cruises for inviting our ORCA on board. This provided us the opportunity to perform deck watches with guests as well as being able to collect important cetacean data, vital to ORCA’s conservation efforts. The charity ORCA is dedicated to the long- term protection of cetaceans (whales, dolphins and porpoises) in British and a- joining waters. Charity No: 1141728 www.orcaweb.org.uk During the Celestial Canaries cruise the ORCA team recorded a total number of 245 cetaceans, which included 6 species including: fin whale, Minke whale, short- beaked common dolphins, striped dolphins, short- finned pilot whales and Risso’s dolphins. We surveyed 3 sea regions: English Channel, Bay of Biscay and North Atlantic Ocean and over 3,659 nautical miles (6 full sea days). We kept both a cetacean and bird list, contributed to by guests on board (please see the end of the report for a map and list of cetaceans and birds). DAY 2 - Friday 15th March 2019 Sea State: 7- 8 Sky: Overcast Temperature: MAX 13°C SEA DAY We saw numerous Gannets during our day at sea Shenaz presenting in the Britannia Lounge The decks were closed today as the sea conditions in the English Channel and Western Approaches were a sea state 6- 7, with a swell height of 3-4 metres for a good part of the day. Our Wildlife Officer, Shenaz, presented a short lecture in the Britannia Lounge in the afternoon highlighting possible cetacean species to be encountered during the voyage. This talk was well attended by many guests. On this day also, numerous Northern gannets (Morus bassanus) were spotted darting in and out of view of the ships’ windows un phased by the rough seas. Northern gannets are narrow- winged seabirds with cigar shaped bodies and long tapering bills which end in a point. The external nostrils are closed as an adaptation for plunge- diving and secondary nostrils above the gape are automatically closed by a flap of skin on entering the water. They swim well and are excellent flyers. The gannet is the largest seabird in the North Sea with a wingspan of around 2m. Charity No: 1141728 www.orcaweb.org.uk DAY 3 - Saturday 16th March 2019 Sea State: 4- 7 Sky: Overcast with showers Temperature: MAX 12°C SEA DAY The ORCA team started the day full of enthusiasm for recording the rich diversity of species found in the Bay of Biscay, despite not having ideal sea surveying conditions for spotting cetaceans. The sea state fluctuated An adult Kittiwake between a 4 and a 7 with a swell height measuring around 2m for most of Photo taken by Shenaz Khimji the day. However, after conducting a 12- hour deck watch, the ORCA team were delighted to have recorded two sunfish, Northern gannets, kittiwakes, one great skua and two unidentified dolphins during the course of the day. The ocean sunfish or common mola is one of the heaviest known bony fishes in the world. Adults typically weigh between 247 and 1000kg. The species is native to tropical and temperate waters around the globe. It resembles a fish head with a tail, and its main body is flattened literally. Sunfish (Molidae) DAY 4 - Sunday 17th March 2019 Sea State: 2-4 Sky: Partly Cloudy Temperature: MAX 15°C SEA DAY Today was the best day of the cruise so far for cetacean sightings, in total five species were recorded including 27 animals. These were enjoyed by guests and the ORCA team alike on deck 12 during a very pleasant sea state travelling off the West coast of Portugal in the North Atlantic Ocean. Common dolphins seen at 17:50 on starboard side, note the yellow hourglass pattern, a key diagnostic feature of this playful dolphin species Charity No: 1141728 www.orcaweb.org.uk Common dolphins taken by Shenaz Khimji on deck 12 Striped dolphin travelling down starboard side at 17:20, note the eye to anal stripe, a distinguishing feature of this species which were feeding close to the Saga Sapphire. Striped dolphin taken by Shenaz Khimji Risso’s dolphins were recorded at 15:57, as featured in the photo below left. This species is a large, distinctive, beakless dolphin with a blunt grooved head (shown in illustration below right) and tall falcate dorsal fin, the body is often light greyish with a white head seen in the centre of the photograph below where the animal is spy- hopping (vertically poking it’s head out of the water). Risso’s dolphins taken by Shenaz Khimji Illustration of Risso’s dolphin head An amazing number (7!) of fin whales were also seen blowing throughout the afternoon near the horizon, followed by a Minke whale which surfaced just ahead of the ship before sunset. Throughout the day, migrating terns from Africa were seen in large swirling flocks close to the oceans’ surface. Fin whale blowing at 18:25, the world’s second largest animal measuring a maximum size of 27m, fastest swimming great whale reaching 24 knots, feeds on krill, fish and squid.

Note the fin shape on the left and double blow hole in the right photo Minke whale surfacing by Hannah Ramsey- Smith DAY 5 - Monday 18th March 2019 Sea State: 3-4 Sky: Partly Cloudy Temperature: 16 °C ARRIVE FUNCHAL, MADEIRA 14:00 DEPART: 20:00 TOTAL: 6 patterned dolphins Today we arrived in Funchal, Madeira. During the morning survey and on the approach to Madeira the ORCA team recorded 6 patterned dolphins (common or striped), Cory’s shearwaters in big numbers, yellow- legged gulls. Whilst exploring Madeira, the ORCA team were lucky enough to spot a kestrel and a number of species of fish in the harbour. Yellow – legged gull Charity No: 1141728 www.orcaweb.org.uk Cory’s Shearwater are very commonly seen flying around Madeira. Pictured above is a large greyish-brown shearwater with whitish underparts and yellow bill. Lacks collar and has narrow white band on the rump. Cory’s shearwaters resting and in flight Shearwaters are long-winged, slender- bodied highly pelagic seabirds. They are nocturnal at the breeding colonies which are often vast. Most species are great wanderers and several are transequatorial migrants. They have slender, tubenose bills with a pronounced hook. The similarity of many species presents a number of taxonomic and identification problems. Flight action is important; the larger species tend to have an undulating flight, gliding on stiff wings interspersed with periods of rapid wingbeats. The smaller species tend to have a more fluttering flight on shorter, more rounded wings. Young male kestrel perched on street light in Funchal, Madeira, photo above taken by Shenaz Khimji Charity No: 1141728 www.orcaweb.org.uk The ORCA team ventured on a boat trip in madeira and were treated to close views of short- finned pilot whales. Note the close proximity of the animals to the shore, which shows how deep the waters are around Madeira. In the image you can see a young animal next to a bull, which has a very wide base to its dorsal fin, note the difference between the bull and juvenile or female shown in the bottom image. Photos taken by Shenaz Khimji in Madeira Charity No: 1141728 www.orcaweb.org.uk A guest photo, taken by Jacqui Palmer of a Boettger’s lizard (Gallotia caesaris). It is a lacertid (wall lizard) endemic to two of the Western Canary Islands, El Hierro and La Gomera. In Tenerife and La Palma it is replaced by its close relative Gallotia galloti. On the Portuguese island of Madeira, it has been introduced by man. A guest photo, depicts a little egret (Egretta garzetta), taken by Dave Jones Charity No: 1141728 www.orcaweb.org.uk DAY 6 Tuesday 19th March 2019 Sea State: 4-5 Sky: Partly cloudy Temperature: 19 °C TOTAL: 19 Striped dolphins 15 Patterned dolphins 3 Minke 1 ARRIVE SANTA CRUZ, LA PALMA 13:00 We arrived at our first Canary Island, the island of La Palma today. The Canary Islands are amongst the most popular whale watching destinations in the world. This is for two reasons, it’s on a migration route for many great whale species travelling to and from wintering feeding grounds. Secondly, the Madeiran Archipelago is volcanic in origin, and due to the lack of a continental shelf, depths drop to as much as 5,000m just 5km from shore, see bathymetric map below. Consequently, cetaceans that inhabit deep waters and are typically oceanic, such as sperm whales and beaked whales are relatively easily observed quite close to the shore. A bathometry map of the Canary Islands This morning, as the ship entered Santa Cruz, La Palma, the ORCA team and passengers were treated to two lovely sightings of common and striped dolphin pods which were attracted to the ship before the sighting of the day; a blowing minke whale just ahead of the bow.

R. Freeman* Canadian Circumpolar Institute, University of Alberta, Edmonton, Alberta T6G 2E1, Canada ABSTRACT: This paper examines the extent to which depleted whale populations have recovered (or not) and their perceived current conservation status and prognosis for continued survival, as repre- sented in the International Union for Conservation of Nature and Natural Resources (IUCN) Red Lists. It is concluded that current hypothetical and untested predictions of extinction risk, while in many cases drawing attention to justifiable conservation needs, may seriously undervalue the resilience of species that have evolved to live in a dynamic and ever-changing reality including cen- turies of heavy exploitation by humankind. The paper questions the appropriateness of Red Listing criteria for long-lived highly mobile ocean-dwelling species that are scarcely affected by the princi- pal threats upon terrestrial or aquatic species living in relatively restricted areas subject to habitat fragmentation and/or loss. This analysis draws attention to the problems associated with objectively assessing the conservation status of charismatic species and the value conflicts that may override evidence-based scientific conservation assessments.

    SC/58/O15 The cetaceans of Guinea, a first check-list of documented species Idrissa L. Bamyψ, Koen Van WaerebeekΩ, S. Sounounou BahΦ, Mamadou DiaΠ, Samba T. DialloΠ, Bangaly Kaba¶, Namoury KeitaΦ , Sékou Konate ¶ and Hassimiou Tallψ 1 Abstract A CMS workshop on West African Cetacea (Conakry, May 2000), called for i.a. ‘carrying out .. inventory of cetacean species; collection, treatment and compilation of data for each state.’ The present paper is a preliminary faunal check- list of cetaceans occurring in Guinea’s EEZ. Information was gleaned from strandings, bycatches, scientific and opportunistic sightings and a literature review. Ten species are included for which supporting voucher material and data were available for examination. These are, three baleen whales: Balaenoptera brydei, Balaenoptera acutorostrata and Megaptera novaeangliae; and seven species of odontocetes: Kogia breviceps, Tursiops truncatus, Sousa teuszii, Stenella frontalis, Delphinus delphis, Steno bredanensis and Globicephala macrorhynchus. Another two species, Physeter macrocephalus and Stenella attenuata were sighted off Guinea but no photographic evidence was obtained. The current account is thought to reflect an incomplete picture of Guinea’s cetacean biodiversity. Future surveys are expected to update and investigate spatial and temporal distribution patterns for each species along Guinea’s coast. A few bycatches landed by artisanal fishers were utilised locally, but there are no signs of any substantial captures. Nonetheless, monitoring should be continued. The set-up of a national reference collection and database is recommended. The population identities of the encountered Atlantic humpback dolphin, minke whale and humpback whale are of particular interest.

  • First List of Cetaceans Encountered Off La Gomera
    21 cetacean species off La Gomera (Canary Islands): Possible reasons for an extraordinary species diversity Fabian Ritter M.E.E.R. e.V., Berlin, Germany. [email protected] www.M-E-E-R.de INTRODUCTION To date, 26 cetacean species are known to inhabit or visit the waters of the Canary Islands (RITTER & BREDERLAU 1998), making the archipelago an important area for cetacean observation. La Gomera (17°15'W - 17°21'W and 28°1'N - 28°14'N) lies about 400 kilometres off the West African mainland in the Atlantic Ocean and belongs to the Western Canary Islands. The islands are steep volcanoes surrounded by deep waters close to the coast. Some authors see the oceanographic circumstances as an absence of a shelf (MARTIN et al. 1992). In the Western part of the archipelago, the sea-bottom drops steeply to about 4.000 metres into the Canaries basin (ROTHE 1986). In the Southwest of La Gomera, a depth of 2000 m is only a few kilometres away from the coast. The climate is mainly determined by the island's position in the north-eastern trade-wind. Water temperatures are approximately 22°C - 24°C in summer and 17°C - 19°C in winter. This temperat- ure is lower than might be expected for a subtropical region, mainly due to the cold upwelling off West Africa and the cooler Canaries Current (FERNANDOPULLÉ 1976). METHODS The platform for the collection of data were small former fishing boats now being used as whale watching vessels and operating in the Southwest of the island.

ILANGAKOON Member of the IUCN Cetacean Specialist Group, 215 Grandburg Place, Maharagama, Sri Lanka Contact e-mail: [email protected] ABSTRACT Sri Lanka is a developing island nation in the northern Indian Ocean. Travellers and historians have documented whales in the waters around the island as far back as the 14th century but the first scientific records of live cetaceans from vessel-based research observations were documented only in the early 1980s. Sri Lanka’s waters have high cetacean species richness with 27 species recorded to date and year-round abundance. Small cetaceans are however increasingly threatened due to the developing fisheries industry, with bycatch being a major cause for concern. Other identified threats include increasing shipping traffic and unregulated marine tourism. Cetaceans are protected by national legislation but implementation of the relevant laws and conservation measures is hampered by resource constraints. The prevailing gaps in knowledge are also due to a lack of resources to carry out dedicated long-term research on cetaceans in a developing country with more immediate human development priorities.

  • Red List of Cetaceans in the Mediterranean Sea and Black
    Red List of Cetaceans in the Mediterranean Sea and Black Sea © Giovanni Bearzi Key Facts Cetaceans are marine mammals: they breastfeed their young and need to reach regularly the surface to breathe. 23 species have been recorded in the Mediterranean and Black Seas from the small porpoise (1.5 m) to the fin whale (20 m). 10 species of dolphins and whales are regularly found in the region. A further 13 species are vagrant and occur infrequently in these waters. Nine cetaceans are qualified as threatened in the Mediterranean basin. This includes the Mediterranean populations of Sperm Whale Physeter macrocephalus and the Short-beaked Common Dolphin Delphinus delphis. The ongoing use of illegal driftnets has had, and continues to have, a major impact on large whales. Since 2001, The “Agreement on the Conservation of Cetaceans of the Black Sea, Mediterranean Sea and Contiguous Atlantic Area” (ACCOBAMS) has worked for the development of cetacean conservation in the region. More scientific data is needed for all the cetacean species, especially in the southern and eastern parts of the Mediterranean Sea. The IUCN Red List of Threatened Species TM Conservation Status Assessment Out of the 13 Cetacean populations assessed in the Mediterranean and Black Seas, one was proposed as Critically Endangered, five for Endangered and three for Vulnerable. Four were considered Data Deficient, meaning that there was not enough scientific information to assess their extinction risk.

Preliminary checklist of Cetacea in the Indonesian Archi- pelago and adjacent waters. Zool. Verh. Leiden 312, 30.xii.1997: 1-48, figs 1-12, tabs 1-4.— ISSN 0024-1652/ISBN 90-73239-59-1. Peter Rudolph, Nordstraße 2, 63477 Maintal, Germany. Chris Smeenk, National Museum of Natural History, P.O. Box 9517, 2300 RA Leiden, The Nether- lands. Stephen Leatherwood, Ocean Park Conservation Foundation, Ocean Park, Aberdeen, Hong Kong. Key words: Cetacea; Indonesia; Malaysia; Brunei; Singapore; Indian Ocean; Pacific Ocean. Records of 29 species of cetaceans from the Indonesian Archipelago have been gleaned from pub- lished and unpublished sources, representing five families: Phocoenidae (1 species), Delphinidae (16), Ziphiidae (3), Physeteridae (3), and Balaenopteridae (6). The presence of 26 species could be confirmed by material in museum collections, photographs or documentation by specialists. The occurrence of three species is still unconfirmed. Obituary Stephen Leatherwood died on 25 January 1997, at the age of 53, after a long ill- ness. With him, marine mammalogy has lost one of its finest workers. His numerous publications, both scientific and popular, have contributed tremendously to the knowledge of marine mammals and the dissemination of this knowledge among a broad public. Those who worked with him were greatly impressed by his zeal and energy, his dedication to the animals and their environment, his clear writing, his charm and integrity, and his constant encouragement of others, professionals and lay- men alike. It was Steve who brought up the idea of compiling our data for this check- list of Indonesian cetaceans, and he wholeheartedly let us have his records.
