Drama on Falmouth Pelagic

I spent the bank holiday weekend away in Cornwall. I travelled down with David, Magnus and Paul. We stopped in South Devon on the way to look for Cirl Buntings and got lucky in Labrador Bay RSPB. Cirl Buntings breed only in South Devon and they can normally be seen no-where else in the UK, though they have recently also been re-introduced into Cornwall.


Cirl Bunting

We continued on to Cornwall, watching a few more birds at Stithians Reservoir, where the highlights were a Little Stint and a Wood Sandpiper. A Little Stint is a tiny wader.

Wood Sandpiper - L, and Little Stint - R

We stayed the night in Camborne.  On Sunday after breakfast, we made our way to Falmouth Marina for the pelagic with AK Wildlife Cruises. What’s a ‘pelagic’ I hear some of you ask?

Pelagic – adjective, pəˈlædʒɪk,  (technology) connected with, or living in, the parts of the ocean that are far from land.

So, for birdwatchers, a pelagic is a boat trip out to sea to find pelagic birds, i.e. those which spend all of their time at sea and never come ashore except to breed.

Now, the pelagic didn't start well. The skipper, Keith, had forgotten the chum in his freezer. Chum is quite important on a pelagic. It's a foul-smelling mixture of mashed up fish but is nectar to sea birds and attracts them like bees round a honey pot.  Keith was very experienced, knew the waters around Falmouth like the back of his hand, and assured us that the lack of chum wouldn't stop us seeing the birds we wanted to see. He knew the signs, he explained, of where the fish would be, based on the activity of gannets far off. Fish attract seabirds.

Paul - L, and me on the bow of the boat.

The section of water from the harbour to the open sea is always a bit quiet. When we reached the open sea Keith, true to his word, spotted the signs of a ‘build up’. We raced towards it and found a raft of shearwaters and other birds sitting on the sea. Most were Manx Shearwater, a common pelagic species, but there were also half a dozen Sooty Shearwaters which are larger and not so common. A good start for Keith then!

All Manx Shearwaters except the one indicated.
Manx Shearwater - L, Sooty Shearwater - R
Sooty Shearwater. Unusual and imposing!

There were also one or two Balearic Shearwaters. Also uncommon and shy!

Balearic Shearwater. Not that common so nice to see.

The weather was mainly overcast but there was very little wind. The sea was like a millpond. I was very happy about this as I had not wanted to take a travel sickness pill. I don't normally get seasick but on pelagics the boat is often left to drift. It tends to rock uncomfortably, even if the sea is only a little rough.

As the day progressed things got better and better. Keith knew his onions as far as cetaceans were concerned and pointed out not only the pod of local Common Dolphins but also a smaller pod of about a dozen Bottlenose Dolphins which had a couple of small calves with them.

Bottlenose Dolphins with calves

Keith invited us, three at a time, to watch from the bow. I was lucky enough to be there when several dolphins delighted in swimming along with us. We were under power and travelling along but the dolphins easily kept pace with us, hardly needing to move a fin, as this video shows. Amazing!

As well as the dolphins, there were also Atlantic Bluefin Tuna present. These enormous fish sometimes jumped out of the water like dolphins. They fed on anchovy fry near the surface and where the tuna were feeding the shearwaters and other sea birds congregated to dive in and enjoy the fish bounty.


Atlantic Bluefin Tuna jumping. These huge fish reach 220-250Kg!

We also witnessed a disturbing incident which brought home the ruthless nature of life in the wild. Skuas are a family of sea birds with a reputation for being aggressive and piratical. They often harass smaller seabirds who have caught fish and force them to drop their food. The Great Skua is a large powerful bird. We came across one attacking a Herring Gull. Most of you will be familiar with Herring Gulls and will know that they are not small birds. Here is how the story progressed.

Great Skua, commonly known as a Bonxie

When we approached, the Great Skua (AKA Bonxie) was attacking the Herring Gull and was clearly winning!

At our approach the Bonxie flew off.

The poor Herring Gull took the opportunity to make a run for it. However, it had been severely weakened in the attack.

When we were a safe distance away again, the Bonxie moved in for the kill! The gull looks terrified!

Shortly afterwards, the Herring Gull was dead!


Before witnessing this incident, I had never thought that a Bonxie would attack such a large prey. We live and learn!


As well as shearwaters, other pelagic birds include petrels, mainly European Storm Petrels and Wilson’s Storm Petrels. Petrels are rarer than Manx Shearwaters and/or are much harder to see on account of their small size. They are really tiny. They are little bigger than a sparrow, weigh only 25-30g, yet they survive at sea in all conditions.  The first time one was spotted I just couldn’t get on it (i.e. manage to see it, usually with binoculars). The same happened with the second sighting, and the third. I was beginning to get desperate! Only on the fourth sighting was I able to see it and take photos. Here is my rather weak effort at a photo. Not only are they tiny and hard to see, they are also difficult to photograph.

European Storm Petrels

In true Blue Peter fashion, here is one I prepared earlier, from another pelagic from the Isles of Scilly in 2009.

European Storm Petrel

Later, we came across a small number of European Storm Petrels just sitting on the sea. I had not seen this behaviour before.

European Storm Petrels. Tiny, cute and weighing only 25-30g!

Later still, we came across two Arctic Skuas - yes, the pirates! Arctic Skuas come in two colours (or morphs). We had one of each. When we got too close, they flew off and attacked a small flock of Kittiwakes.

Arctic Skuas. Dark morph is on the left and the pale morph on the right. They are robbers!!

Arctic Skua - Dark morph

The missing chum may have brought the diminutive Petrels a little closer to the boat if they had been tempted in by it. We may have seen them closer, or we may have seen Wilson’s Storm Petrel too. Who knows? At all events, it was a very enjoyable pelagic.

The following day we came home via Kynance Cove on the Lizard peninsula. Highlight of our walk was a Red-billed Chough. 

(Red-billed) Chough. Rare outside of the far West of Cornwall and some areas in the West of Wales!

Before leaving for home, we also enjoyed a Cornish cream tea, jam first of course!

Albatross at last

You have probably heard of an Albatross. You may not know that they normally roam around the Antarctic and Southern oceans, a very long way from the Northern Hemisphere. So, it was quite a surprise when, in 2017, a Black-browed Albatross with a wingspan of about 2.40m, was seen off the cliffs at Bempton in East Yorkshire. It stayed for a couple of days and then disappeared until 2020, when it returned for a few days.

In 2021, Albert Ross, as it is affectionately known (and presumably the same bird) reappeared on 28 June and has been seen almost every day since. Now, I have never seen an albatross anywhere in the world on my travels, so I just had to go and see it. He'd been seen every day for several days, so I went up on 6 July with Magnus Andersson intending to stay two nights. Magnus had already seen it!

The Albatross had been seen that morning, but by the time we arrived it had disappeared. It didn't reappear on 7 July, nor again on the morning of 8 July when we had to return. My disappointment was somewhat alleviated by seeing a magnificent Western Rufous Turtle Dove at Spurn, along with Spoonbills, Barn Owl and a few hundred Little Gulls. 

Western Rufous Turtle Dove. - Very nice, but not exactly an Albatross!!

Angry Spoonbill advances!

Out of my way. I'm feeding here!

Barn Owl came out at dusk to hunt.

It was frustrating that the Albatross returned the day after we got back but I couldn't go again because we had booked a 10-day holiday in Cornwall and Devon. It was seen almost every day while I was away!

Eventually, I went up again on Friday 23 July. The Albatross  disappeared again on that day and it was not seen on Saturday 31 July either!  I decided to stay one more night just in case it turned up on Sunday morning. Luckily for me, it did! I was staying 10 minutes from Bempton.  When I arrived at about 8:30, the Albatross was sitting on the sea about 300metres off shore.  Even with a telescope it looked quite small and unimpressive. Nevertheless, the other birds were stupendous to watch.


Great Skua offshore

Puffin - everyone's favourite. The foreground bird is a Razorbill

Kittiwakes. The chicks have a black ring on their neck and other black markings. They are born and fledge from these narrow ledges!! The chick at the bottom is covered in guano from the birds above! 

Guillemot. They have small wings and have to flap them very quickly!

Fulmar - Not  gull, but a bird that is quite pelagic (spends most of its time at sea).

Razorbills are one of my favourites. They are tiny next to the mighty Gannet.

Razorbill - You can see they are a little dumpy and have tiny wings. It's a wonder they can fly!

Razorbills - I love them!

Gannet. Built for speed in diving. Plunging from great height into the sea to catch fish. 

FINALLY - the Albatross!

Speaking with one of the volunteers at RSPB Bempton, I learnt that the Albatross would probably come off the sea in a couple of hours and soar around the cliffs for a while before settling. He advised me to go to the next viewpoint, which I did.  Sure enough, just after 11.00 Albert Ross came into view, to the delight of everyone present, and wheeled around for about 20 minutes before landing on the cliff around the corner. I took some flight shots of this magnificent bird.


Black-browed Albatross - the other bird is a Gannet, certainly not a small bird, larger than a gull!

Black-browed Albatross - what a bird. A long distance flier - normally, it hardly has to flap its wings!

Mission accomplished, I started home, via Frampton Marshes RSPB to see the Pacific Golden Plover and a few other birds that I hadn't seen this year. These included Curlew Sandpiper, Wood Sandpiper and Spotted Redshank.


Wood Sandpiper - passing through on migration

Snipe - not uncommon, but hard to see owing to it's superb camouflage. This one is right out in the open.

Spotted Redshank. Again, on migration. A much finer bill than the Common Redshank.

Avocet. This is a juvenile. Adults are black and white.

My wife had arranged to go out with a friend of hers the following day so I decided to go to Snettisham for the night ready to look for the Western Sandpiper the following day. This very small American wader was best seen either shortly before or shortly after high tide, which was at 08:30 next morning. I was lucky to find a room in the Queen Victoria pub, Snettisham. I got down to the beach in time, but the bird was not seen before high tide. As a large flock of Dunlin and Sanderling roosted on the shore waiting for the water level to drop, we scoured hundreds of small birds looking for the one that looked slightly different. Someone did find it and called it out but just as I got my binoculars on it, the whole flock flew off and landed in a position where it was impossible to see most of them. We waited for the water level to drop and the birds then started moving onto the mud to feed. At that time, I was able to photograph the Western Sandpiper, which looked remarkably similar to a sanderling.


Western Sandpiper - An American wader which is way off course!

Western Sandpiper - Arrowed!

Sanderling. They look superficially like the others but are more scaly above and with no black belly.

There was time for a brief stop at Titchwell Marsh RSPB, where the highlight was a Great White Egret. While there, I got talking to a couple who had seen a Little Owl that morning. I hadn't seen Little Owl this year. As it was on my way home, I dropped in to Abbey Farm NR, a small reserve with a single small hide. As I entered, the Little Owl was sitting in front of me. A Marsh Harrier visited before I made my way home to Sutton.


Little Owl

Marsh Harrier. This is a male.

Altogether a very enjoyable trip. I was so pleased to see The Black-browed Albatross, a truly magnificent bird.

Telephoto lenses - Fitting a sling attachment.

This article shows how to use a telephoto lens on a sling. I like to carry my camera and lens on a sling so it is 'ever-ready'. Here's how to do it. The pictures show a Nikon 500mm PF, but this technique applies to any lens with a removable tripod foot.

Firstly, remove the Nikon tripod foot. This is rather flimsy anyway!

Take off the tripod foot.
Buy some tripod socket eyes/screws like the ones on the left. I got these from Amazon. They were called Camera Tripod Mount Screws. I also tried the ones on the right. I didn't find them suitable and I advise against them.

I found the rubber washers that came with the screws to be too soft and too thin. I replaced them with harder thicker tap washers as shown below. The tripod eye is 20mm in diameter. The original washers are about 2.2mm thick. The replacements are 4mm thick.

Original washers on the left. My replacements on the right.

I use an OpTech USA Utility Strap Sling. It's very reasonably priced, widely available, in a very flexible system and compatible with a wide range of other OpTech straps. It is also light, stuffs easily into a bag and has no metal parts to damage your equipment. The Utility Strap Sling comes with a set of webbing loops, but if you need more (perhaps to attach to another camera) you can buy other sets like this:

Extra Uni-loops to fit all OpTech straps are widely available.
Attach the male loop to the tripod eye. That's if you wear the sling on your left shoulder, as I do. If you wear it on your right shoulder, use the female loop. This is so you can clip into the nearest clip on the sling.

Screw the attachment into the tripod socket on the lens. With the thicker washer there should be 2.5 complete turns of the eye before it's tight. I've been using it like this for a year and it has never come loose.

Clip it onto the sling and you're ready.

Sling attached.

With the camera on the sling, it can be slid up into shooting position very quickly.

Sling in action. Note that the second clip is left behind when the camera is slid up and is somewhere under my right arm.

Now, if you're worried that holding your expensive camera and lens on a single plastic clip is too risky, let me re-assure you. From 2006 to 2012 I used a Canon 500mm f4 with various bodies (combined weight about 5.5 Kg). From 2012 to 2019 I used a Canon 500mm f4 Mk2 which, with the 7D2 gave a combined weight of about 4.5 Kg. I only ever used one clip normally!  Just occasionally I would attach a second clip, e.g. when crossing remote rain-forest rope-walks 30m above the forest floor or while on a canoe ride in choppy rivers.

The Nikon lens with D500 body weights only 2.5 Kg, so no problem at all for one clip.

Sometimes I use a tripod. Because I use an Arca Swiss ballhead, I bought a cheap replacement Arca Swiss compatible foot. It is actually more robust than the Nikon original. The tightening screw is very solid.

With the OpTech loop attached I can still use it on the sling. When I need to use the tripod, I don't need to detach the loop to fit it in my (Markins) ballhead. 

I love the small size and low weight of this lens. Optically, it's no better than the Canon 500 f4, but it's just so much easier on my shoulder.

All photos on my blog for Kenya, Scilly Isles and from April 2019 taken with this lens and D500 body.

Flaming Firecrest

Spring is such a wonderful time. All the birds are singing. I'm so lucky I can still hear them all at my age! On our daily exercise walk today on Banstead Downs (NB less than a mile from home) saw a gorgeous Firecrest like I've never seen Firecrest before.

Firecrest. I've often seen them like this. The crown stripe is attractive.
Firecrest. When they turn their head, the crown stripe is very obvious.
Firecrest. Sometimes you get a 'mohican' flash.
Rarely do you get a 'brain surgery' display like this. Now I know why they're called Firecrest.

Firecrests are almost Britain's smallest bird. They weigh a mere 5-7 grams and are about 9cm long. Constantly moving, they are often difficult to see as they flit restlessly from branch to branch. 

The last of the blossom makes a lovely background for this Goldfinch.


And Britain's smallest bird? - Not the Wren. It's the Goldcrest, which is slightly smaller than, and a cousin of, the Firecrest.
