Arran Dunn, Hampton Boys School, 19th-23rd August 2013

By the time it came to my last day at the CBMWC it seemed like a lifetime since I had I arrived on the Monday morning thinking that I would be lucky to spot one dolphin during my week of work experience. From the moment I arrived I immediately felt part of the team because everyone was very friendly and quickly allowed me to be involved. In only a few days I did so many new things and learnt so much. I carried out five land watches, which involved sitting on the harbour wall with binoculars at the ready, and I saw at least one dolphin almost every day, including a mother and calf. In fact on the first day alone I saw seven! On one day a dolphin jumped clear of the water not far from the rocks below and I also saw diving gannets and a seal that appeared only a metre from the sea wall. It was fantastic!

At the centre it was no less interesting: I inputted the data from our watches into various databases, including writing up notes which I posted onto the CBMWC website and facebook page; I also went down to the beach with another volunteer to collect mussels and a shore crab to put inside the rockpool tank then spent an hour weaving through hundreds of sunbathers to pick up over four hundred pieces of litter!

Friday arrived too quickly and there was still one thing I had not done: I had not gone out on a boat to see the dolphins in the bay and this would only be possible if the boat was not fully booked. I was worried though, because the Dolphin Survey Boat Trips are very popular and my final day was almost coming to an end with the final trip booking up quickly. I waited patiently in the visitor centre hoping that there would be enough space for me, although it wasn’t looking likely as customers kept on arriving to book their places. In fact I had almost given up hope. Then 3.30pm arrived and suddenly my wish was granted. I managed to get a place and this proved to be the finale of my week and something that I will always remember. Out in the bay I spotted several dolphins and then two dolphins dived directly under the boat as we made our way back to the harbour. They were beautiful and they came so close that I could see them perfectly from above as they swam through the clear water.

Thank you to everyone at the CBMWC for making my week with you amazing and probably the best work experience ever.

The possible reasons for bottlenose dolphins (Tursiops truncatus) participating in non-predatory aggressive interactions with harbour porpoises (Phocoena phocoena) in Cardigan Bay, Wales

Leonora Neale BSc (Hons) Zoology, University of Nottingham

Abstract

Between 1991 and 2011, 137 harbour porpoises (Phocoena phocoena) died as a result of attacks by bottlenose dolphins (Tursiops truncatus) in Cardigan Bay. The suggested reasons for these non-predatory aggressive interactions include: aberrant behaviour, geographic overlap, dietary overlap, object-oriented play for infanticide practice or for fighting practice, elevated testosterone levels during the breeding season of bottlenose dolphins or skewed operational sex ratio of the bottlenose dolphins (the number of sexually available males relative to sexually available females).

Geographic overlap and object-oriented play for infanticide practice and fighting practice were investigated using boat survey data (2005-2011) from the Cardigan Bay Marine Wildlife Centre and strandings data (1994-2011) from the Cetacean Strandings Investigation Program. Dietary overlap was examined by reviewing literature based on stomach samples taken from the two study species located in the British Isles. The remaining factors were not investigated due to time and equipment constraints, and aberrant behaviour was dismissed, as there is widespread documentation of non-predatory aggressive behaviour between bottlenose dolphins and harbour porpoises.

Results showed that there was a minor geographic overlap; under a fifth of each species’ area coverage, and thus it was unlikely to cause the attacks. There was a dietary overlap; although the extent of the overlap is uncertain, so dietary overlap remains a possible cause of the non-predatory aggression. Object-oriented play for infanticide practice seems to be unlikely, as only three bottlenose dolphin calves died
(with unknown cause of death) over 18 years, indicating that either infanticide is not occurring or it is extremely rare. Object-oriented play for fighting practice was supported by literature but the results were inconclusive, therefore, it is also considered a possible reason for the attacks on harbour porpoises. Further investigation is required to determine which of these possible reasons is the definitive cause of the non-predatory aggression.

Cornwall Seal Group extend ID into Cardigan Bay

Girlie the Atlantic grey seal is no longer just another grey seal among the many that delight locals and visitors to Cardigan Bay – she’s now one of a select group who, it’s hoped, will reveal their traveling habits over their lifetimes. Girlie, along with almost a hundred other Atlantic grey seals from Cardigan Bay are now the stars of their own photo identification catalogue – a sort of seals’ family album.

Girlie was first snapped by Cornish couple Dave and Lesley Jarvis in 2009 while out on a survey with researchers from CBMWC. Dave and Lesley have taken thousands of photos of seals on the last four of their annual holidays to New Quay. Thoroughly organised on their return home, they have carefully sorted their photos and with help from Sue Sayer – a seal identification expert who set up the Cornwall Seal Group and established the seal photo-ID catalogue along with Dave and Lesley -these have been worked up into an extensive seal photo ID catalogue for Cardigan Bay, alongside a spreadsheet of sightings.

During a recent boat survey, CBMWC’s science officer Sarah Perry tagged one of the seal photos she had taken with Sue’s name on facebook. The beautiful adult female seal – CBF10 ‘Plus plus girlie’ was quickly identified by Sue as one previously sighted by Dave and Lesley in 2009. Incredibly CBF10 had previously been identified on 28/06/09 and re-sighted on 26/06/13 – almost exactly four years later. The next step will be to find out if Girlie features in photographs taken in Cornwall, or further afield.
But how exactly do you recognise a seal? With dolphins we use on their dorsal fins but with seals we use pelage markings – the patterns on their fur – so even if you can just see its head you can match the markings with photographs.
In Cornwall, Sue has been poring over photographs of seals taken locally for 14 years, and has already identified nearly 40 animals that split their time between Cornwall and the Pembrokeshire islands of Ramsay and Skomer and even Brittany. “It’s pretty hard to match the markings but I’m used to it now, my brain computes it pretty well and I can recognise hundreds of seals by eye”, said Sue. “And yes, I do give them names – although I’m a scientist – to ‘tag’ them in my head. The full name of the seal in the photograph for example is Plus-Plus-Girlie, because she has two marks like plus signs and the symbol for female on her neck”.
Back in New Quay researchers at CBMWC are hoping that Girlie’s photograph will turn up among those taken in Cornwall. “We know that seals are highly mobile animals so we’ll continue collaborating with Cornwall Seal Group to build up a Cardigan Bay seal photo ID album, and it will be interesting to see how many animals can be identified” commented Sarah.

Special thanks go to Sue Sayer for her help in identifying Girlie and Dave and Lesley Jarvis for persistently taking and organising their thousands of seal photos taken on their annual holidays.

About the Cornwall Seal Group
Initially the group was set up to monitor the presence (or absence) of seals in one north coast colony. A digital identification photo album for seals at this site has been built up since June 2000. Since 2008, monitoring and identification work has spread across Cornwall and Devon and many local volunteer surveyors record seals in their own patch on a regular basis. This work requires considerable patience and a commitment to regular (and often lengthy) visits to the local clifftops! The group first met in February 2004, has over 200 members and meetings are now held once a month.

Environment Wales project grant awarded to CBMWC

We have just received the fantastic news that we have been successful in our small project grant application to Environment Wales. The grant – worth over £900 – will be used to purchase a 500mm lens for use with our land watch camera.

For the past eight years researchers from CBMWC have been photographing dolphins whilst out at sea on research surveys, in order to identify animals, usually by unique nicks, notches and scratches on the dorsal fin. In order to approach the animals close enough to photograph their fins, we need an official licence, the terms of which prohibit us from doing this in the harbour area because it’s felt this would set a bad example to recreational boaters and result in disturbance.

However, it’s important to identify animals using the harbour area to build up a useful picture of how they use the site. Bottlenose dolphins have what are called home ranges and are frequently seen at specific sites each year. We are keen to discover how many of the same individuals revisit the New Quay harbour area and which other areas in Cardigan Bay are important to them.

Last year with grant aid from Natural Resources Wales we bought a camera to use during our land watch surveys to photograph the animals in the bay without disturbing them, but we’ve found we need a more powerful lens so the photographs are detailed enough to analyse. Unfortunately these are very expensive but thanks to this project grant from Environment Wales we can now extend our photo-ID work and find out if the same animals visit the harbour every day and whether they return year after year.

CBMWC would like to say a huge thank you to Environment Wales for this grant and their continued support of our project.

As I am going into my last year of 6th form working at the Cardigan Bay Marine Wildlife Centre has been a wonderful experiencethat has helped me get closer to a decision on what I would like to do in the future which is to work in animal conservation.
It was great shadowing the volunteers who were welcoming and friendly. My jobs ranged from litter collecting on the local beaches and writing up and inputting the previous day’s data from the boat and land surveys. I participated in many land surveys myself in which I learned how much work and effort is put in and the importance of conserving marine life around Cardigan Bay. I was fortunate to see many dolphins from the vantage point of the harbour wall and also a grey seal!
To end an enjoyable week I was able to go on a boat trip on the Anna Lloyd with skipper Steve, where I saw seals basking on the rocks and dolphins which came very close to the boat.
Thank you to Laura and the volunteers for my fantastic and memorable week

My week at Cardigan Bay Marine Wildlife Centre was fantastic, it was truly amazing.

I arranged for my work experience to be done in Cardigan Bay Marine Wildlife during my first year of GCSEs to provide the experience of marine wildlife as in the future I would like to become a marine biologist. Throughout my week in New Quay I was lucky enough to have the weather on my side as it was a lovely sunny week. I gained a lot of experience through participating in a wide range of the activities like completing a survey on the boat which helped me understand why the sea state and wind direction was needed. Also throughout every day I was able to help take bookings for boat trips and help sell the merchandise in the visitor centre. I also did office work on the computers which included noting down the sightings that were seen the day before and publishing them on the website and on the CBMWC Facebook page. Although I didn’t get to see any harbour porpoises or any Atlantic grey seals, I was lucky enough to see bottlenose dolphins every day of my week and even witnessed a dolphin swim under a boat and forage for fish while I sat on the pier doing land watch. Everyone was friendly and willing to answer my questions.

I loved this week and I am considering volunteering in a few years. I would like to say a big thank you to Laura and the volunteers for such an amazing time.
