Wild Ireland - Basking Sharks



As many of you know, I have an interest and involvement in marine activities in the waters of West Cork. Some days the weather is just gruesome, other days it is just amazing, and so I look back with joy at a 'flaming first of June' last year. This was a day when basking shark activity was particularly spectacular, as was the minke whale activity but it was the former that was creating the headlines.

For a couple of weeks last summer, basking sharks were being seen off the coast, just outside Castlehaven harbour and also in Toehead Bay, my home patch. Each evening we could watch upwards of a dozen 'baskers' skulking around the waters in an effort to make the most of the feeding in the plankton-rich water. This activity came to the attention of a great Irish naturalist, film-maker, and regular visitor to West Cork, Colin Stafford-Johnson



I too was making the most of the increased activity and was getting out with Cork Whale Watch on the Holly Jo as much as I could, and on this particular day, we had to wait for the boat to come in, as yer man had grabbed the opportunity to get out early on the water with the film crew and his curragh, in search of these basking sharks.










Needless to say, a successful morning out filming rendered a slightly later than planned return to Reen Pier, thus pushing the start of our own trip on a bit but we didn't mind. Pádraig Whooley of the Irish Whale and Dolphin Group launched into an impromptu and entertaining pier-side seminar on cetaceans for the benefit of those who hadn't been whale, or indeed, basking shark watching before.








With Colin no.2 now safely back onto land, (a sunny backdrop of Castletownshend behind him) we were able to look forward to going out on our own trip with Colin no.1. With the Holly Jo dwarfing the curragh which Colin Stafford-Johnson was using as his signature filming platform, we were content with the relatively larger viewing platform from which to make our observations








With the drone having done its' work for the day, it was packed carefully away into the box, the aerial shots providing an even better perspective than ever I could manage of these gentle giants of the sea, from the viewing platform on the Holly Jo.




Not knowing the actual schedule for the resulting programmes, I was delighted to see part 1 of Wild Ireland: The Edge of the World scheduled, appropriately for St Patricks' Day last week, with part 2 to be shown tonight at 9pm on BBC2. This week, showing the basking sharks in Donegal, in the north. A quick message to Colin Stafford-Johnson checking to see if the West Cork 'baskers' would also feature rendered this reply.

"Hi Celia.
Sharks were filmed in several places but could only be shown in one as it were.....I think they placed them in Donegal in this episode...Colin."

So you never know, it might be this one above which features this evening...well I would like to think so!



Do try to catch Wild Ireland: The Edge of the World tonight, or on catch up iPlayer - wonderful escapism in a week that will be memorable for tragic reasons.

Escape to West Cork




It is the time for our annual May break in West Cork and I can't say how much I have been waiting to get back out here for an escape, after the many things that have been happening during recent weeks.
Our regular, if today, rather bracing walk around the Head blew away the cobwebs and we were once again able to sit and take in the beautiful views, the wonderful colours and the delights of watching gannets diving for fish, just off the rocks ahead of us.




I had simply gone out, armed only with my 24-105 lens and no filters, so the stunning colours are purely as seen.
Could it be any better? Well yes, if the wind would just calm down a bit, there might be the possibility of spotting a minke whale or two off the coast, or maybe even a basking shark, which are currently known to be in the area.
We can but hope.








As well as the stunning scenery, the fresh new growth is taking shape along the verges - the majestic gunnera, the wild garlic, and best of all, the first jewel-like glimpses of the flower of West Cork, the fuchsia.

Ahhhh! I can breathe again.



______________________________


If you too would like to escape and enjoy the delights of West Cork whilst learning the basics of photography, I am announcing that I hope to be running exclusive short breaks in the Autumn.
Details are to be finalised, but if this appeals to you, please do register your interest and I can forward the information as it becomes available.

Humpbacks in April (Pt2)





Firstly it is very important to point out that both humpback whales (Megaptera novaeangliae) and basking sharks (Cetorhinus maximus) are protected under European and UK law, so it is illegal to disturb or harass them.

Second, the trip documented here was a research trip where all necessary licences had been obtained beforehand, so as to carry out the procedures described.
__________________________________________________________________________


Before you get all excited that there has been another wonderful encounter with humpback whales off the West Cork coast, let me stop you there, as this post is the follow-on that I promised, in part, to Padraig Whooley of the Irish Whale and Dolphin Group. I did 'pretty' in (Pt1) and now the 'important' stuff is here in (Pt2) I make no apologies for presenting it in a way that is easily comprehendable for those where science may not come naturally.

It would be a good end to the day to manage to tag
this basking shark.

The tagging will provide scientists with opportunities to gain information regards the otherwise little known migratory habits of the basking sharks.

The Shark Trust has published a code of conduct to be followed in any basking shark encounter. Key points to note are:
  • Keep your distance: keep at least four metres between you and the shark so as not to startle it. If you are swimming with other people, stay in a group, but don't invite others over to take a look.
  • If you're in a boat, turn off your engine (boat propellers are a major cause of serious injury to basking sharks feeding near the surface)
  • If you have a camera handy, take lots of photos of the dorsal fin and any distinguishable features on the shark, as this may help the researchers identify the individual
  • Move away gently and quietly and report your sighting to the Shark Trust
Similarly, sightings of cetaceans anywhere around UK waters should be reported to the appropriate local groups and in Ireland to the Irish Whale and Dolphin Group

The biopsy samples taken were part of an important research tool where they will provide a range of genetics and pollutant information, and where it is not possible to obtain this data any other way from healthy specimens.


Conor Ryan is currently continuing a period of humpback whale study in Cape Verde and you may like to keep up with the happenings in his blog


The Irish Whale and Dolphin Group will be running whale watching weekends on Cape Clear during the summer details are available on their website.


Colin Barnes runs whale and dolphin trips out into West Cork waters. Details on his website.

Again, my thanks to all involved.

Humpbacks in April (Pt1)


Humpback whale HBIRL20 off the Stag Rocks, Co Cork

And so it has happened! I was exceedingly fortunate to make a trip out on The Holly Jo, to look for humpbacks on Saturday 7th April. Firstly it wasn't a normal charter for Colin Barnes. This was a research charter by SEAI with the IWDG and with serious scientific study scheduled. (I will be making a second post about the trip which will feature this work) Secondly, it had been unheard of to find humpback whales in these West Cork waters in April. Colin had been out on a fishing charter the previous evening and had come across the humpbacks again, further west from Galley Head where we had seen them last Tuesday. This was enough evidence for the research trip to be organised at short notice for the next day.

I couldn't believe that the weather was so perfect on the Saturday morning. Calm seas with an off-shore breeze and sunshine. Just perfect for me, the poor sailor, although I was taking no chances and popped two of the little 'sailors helpers' regardless. I was not going to have a repeat of a previous trip I had had with Colin where I spent the whole trip in the wheelhouse feeling rather green having been assured by my better half I would be fine without the pills. (That's the last time I take his sea-faring advice!) Apart from which, we saw nothing, and sadly, it also happened on the second family trip out with Colin, which is practically unheard of but probably down to the early time in the season. If anyone can seek out the whales and dolphins, Colin can. He is legendary in these parts. Who knows what went wrong on those two trips but on Saturday I wasn't bothered about the past. I was just looking forward to finally encountering these splendid creatures close-up.

We had scarcely been at sea for 15 minutes from Castlehaven when there was the first call of "Blow!"


This was to be the start of a most amazing seven hours that I will never forget. The scientific work started immediately and I will detail this in Pt2 of the blog. I am now going to make my apologies to Padraig Whooley from the IWDG as this first blog post is going to be, as he puts it, 'the pretty pictures'. Padraig, the science bits will come, I promise!
I was so engrossed, I had no time to think about my sea-faring well-being. This was wildlife observing at its best. Close to home, on a perfect day and at a time of year it wasn't expected. To top it all, we also observed a new humpback, HBIRL20 which became the latest addition to the West Cork records, swimming alongside HBIRL18 who had already been consistently observed off the South coast of Ireland over the previous few months.

HBIRL18 & HBIRL20 under Toe Head, West Cork
Looking up from the action, I realised we truly were on my home patch, right under Toe Head. We had gradually drifted westward with the tide and the huge shoal of herring and mackerel that the whales were feeding on. I only hoped my better half had been able to pick up my text alerting him to pop out onto the Head to look out at the action. And action was what we were getting. A spectacular display of lobtailing meant that all camera shutters on the Holly Jo were clicking away faster than Denis Noonan playing the bones in De Barras.






We were all aiming for fluke shots of the new addition, an important part of documenting the individual whales, Each whale has unique colouring, shaping and markings and by taking images of the flukes from the top and underside...

and also their dorsal fin from both left and right side...

it is possible to make future sightings accurate.

After easily securing the ID images, we were all able to watch and enjoy this amazing behaviour, their flukes repeatedly pounding the surface of water creating the inevitable spectacular splash.

The day had passed very quickly, and with some successful scientific work having been carried out, plus sightings of at least four basking sharks and possibly a small minke whale, the experience for me couldn't have been far more removed from my first trip out on the Holly Jo. Just amazing!

The following morning we found ourselves in the company of Colin up on the headland, both of us with binoculars poised. Colin had thought he had glimpsed a whale but as we sat and observed for around an hour, it appeared that the humpbacks might have retreated back East along the coast. Wherever they might be, it is only through sensitive and controlled study of their movements that we might learn to understand their life patterns and why they might be in the waters of Southern Ireland during this time of the year.
