<div class="MsoNormal">My name is Alan Gray and along with ‘semi-retired’ colleagues have the</div><div class="MsoNormal">good fortune and privilege to operate<a href="http://www.shearwatercruises.com/"> "Shearwater"</a>, a large catamaran charter</div><div class="MsoNormal">cruiser, based in Pwllheli Marina in North Wales. We conduct coastal</div><div class="MsoNormal">wildlife cruises along the Llyn Peninsula, visiting seal and seabird</div><div class="MsoNormal">colonies. On most of our cruises, we can expect to be joined by the resident</div><div class="MsoNormal"><a href="http://www.llynmarinecharters.supanet.com/dolphinsofllyn.htm">bottlenose dolphins</a>. The catamaran hull format of "Shearwater" seems to be particularly attractive to the dolphins that obviously enjoy riding the considerable double bow-wave that is produced.</div><div class="MsoNormal"><br />
</div><div class="MsoNormal">Our cruises take us to both of the two main <a href="http://www.llynmarinecharters.supanet.com/sealsofllyn.htm">Grey Seal</a> colonies off the Llyn Peninsula. A group of approximately 150 seals inhabit the islands of St. Tudwals, off Abersoch</div><div class="MsoNormal">and a much larger colony is to be found around the shores of Bardsey</div><div class="MsoNormal">Island. Small satellite groups occasionally detach themselves from these main populations and may be found in places such as the Gwylan Islands and Cilan Headland with a more notable, semi-permanent group residing on the northern coast of the Llyn Peninsula, near Porth Dinllaen/Nefyn golf course. </div><div class="MsoNormal"><br />
</div><div class="MsoNormal">The rocky coast and offshore islands of the Llyn Peninsula offer</div><div class="MsoNormal">important nesting sites for<a href="http://www.blogger.com/goog_607091699"> </a><a href="http://www.llynmarinecharters.supanet.com/birdsofllyn.htm">seabirds</a>. Notables such as Manx</div><div class="MsoNormal">Shearwaters, Puffins, Razorbills, Guillemots, Black Guillemots, Shags, Cormorants,</div><div class="MsoNormal">Kittiwakes, along with other Gull species are commonly seen.</div><div class="MsoNormal">Terrestrial predators such as Ravens, Buzzards and Peregrine Falcons, inhabit the </div><div class="MsoNormal">sea cliffs and rocky islands as do the Chough which is a common resident</div><div class="MsoNormal">along these shores and, happily, is firmly established and doing well.</div><div class="MsoNormal"> </div><div class="MsoNormal">This northern part of Cardigan Bay is also blessed with some very</div><div class="MsoNormal">unusual and spectacular marine wildlife. Few people realise that these</div><div class="MsoNormal">waters provide a home for the Leatherback Turtle, the only warm blooded</div><div class="MsoNormal">reptile in existence. These huge creatures, often weighing 1 metric</div><div class="MsoNormal">ton and approaching 3 meters in length spend most of their adult life</div><div class="MsoNormal">here, feeding on the vast shoals of Barrel Jellyfish (Rhysostoma).</div><div class="MsoNormal">The Harbour Porpoise, that seems to be under threat elsewhere can be</div><div class="MsoNormal">seen readily, feeding off the headlands of the Peninsula, particularly</div><div class="MsoNormal">within the area of Bardsey Sound. Here also one can sometimes see the enigmatic</div><div class="MsoNormal">Rissos Dolphin, that otherwise plies up and down the Irish Sea in</div><div class="MsoNormal">pursuit of squid and other prey. These creatures have a blunt nose, are</div><div class="MsoNormal">light grey in colour and bear numerous large scratch marks, inflicted during</div><div class="MsoNormal">play/mating activity.</div><div class="MsoNormal"><br />
</div><div class="MsoNormal">Easily the most spectacular creatures we encounter on our wildlife</div><div class="MsoNormal">cruises are the Bottlenose Dolphins. The groups we see are part of the</div><div class="MsoNormal">Cardigan Bay population that exceeds 360 individuals (although we are</div><div class="MsoNormal">finding more each season). Whilst running our wildlife cruises, we have</div><div class="MsoNormal">for the last few years undertaken dolphin Photo-ID and monitoring tasks on</div><div class="MsoNormal">behalf of the "Seawatch Foundation", a charitable body responsible for</div><div class="MsoNormal">monitoring cetaceans around the coast of the UK.</div><div class="MsoNormal"><br />
</div><div class="MsoNormal">Our work with “Seawatch” has given us a considerable insight into the</div><div class="MsoNormal">behavioural characteristics of the dolphins. We can also, now, readily</div><div class="MsoNormal">recognise individuals (from marks, scratches and pieces missing from</div><div class="MsoNormal">dorsal fins). "Seawatch" also kindly send us feedback from our inputs</div><div class="MsoNormal">and it is interesting to examine the travel itineraries of some of the</div><div class="MsoNormal">individual dolphins we see. We have for instance, taken a photograph of</div><div class="MsoNormal">a dolphin on a particular afternoon and the same animal has been recorded</div><div class="MsoNormal">off New Quay, almost 50 miles away the very next day. We often see the same</div><div class="MsoNormal">groups day after day, but occasionally we will encounter a huge pod,</div><div class="MsoNormal">numbering up to 50 individuals that have simply come up to our area</div><div class="MsoNormal">from the south of Cardigan Bay on what seems a fleeting 'round-the-bay'</div><div class="MsoNormal">tour, describing a large arc and heading back south again.</div><div class="MsoNormal" style="text-align: justify;"><br />
</div><div class="MsoNormal">Having been running the <a href="http://www.llynmarinecharters.supanet.com/coastalcruises.htm">“Shearwater Coastal Cruises”</a> for the last 9 years we do get a feeling for the absence, decline or abundance of wildlife species from season to season.</div><div class="MsoNormal">Anecdotally, of course, we notice that the auks, Herring Gull and Kittiwake numbers vary the most from one year to the next. We seem to have a gradual increase in the Chough population and Herons, with their heronry in Pwllheli town, seem to have increased markedly. Over recent years we have noticed the presence of the odd Red Kite, presumably due to the expansion of the mid-Wales population and Peregrine Falcons seem to have increased. </div><div class="MsoNormal"><br />
</div><div class="MsoNormal">The Grey Seal population seems to have steadily increased over this period and we see more dolphins now that we did before, but this may be due to our becoming more familiar with the location of their favourite feeding areas and developing a more practiced eye. We have not noticed any decline in the number of porpoises we see, but we have realized for some time that they will always keep well away from any areas where there are dolphins. The area does attract a lot of recreational boat traffic at peak holiday times and we notice that dolphins can be reluctant to visit or remain in their favourite feeding areas at these times. The opportunity is not lost on porpoises that soon take their place once the dolphins are absent.</div><div class="MsoNormal"><br />
</div><div class="MsoNormal">In summary, the wildlife we see daily seems to be thriving and numbers seem to be at least similar to those we saw when we began 9 years ago, with a number of species increasing markedly. Furthermore, the Llyn Coastal area is apparently being blessed with the increasing presence of the otter – as if we needed any further encouragement to put to sea every day! </div><div class="MsoNormal"><br />
