I have attempted to categorise and separate out the science, snaps, songs, and birds posts, so that you can focus on just one subject, there is lots of overlap. For example in a post about research into a particular species of bird where I have illustrated it using my own photos or in a song with lyrics inspired by a scientific principle or discovery, again where I may have illustrated the post with my photos (birds or otherwise). Hope it’s useful…

More gulls and other birds and more in my Isles of Scilly gallery on Flickr. There are also my more serious blog posts about IOS with photos.
I started a blog post about the Isles of Scilly (#IOS) while we were island hopping there in July 2018, I was originally going to call it “Cornwall on Steroids”. My muso mate Graham gave us some pointers on IOS and he calls it Cornwall Plus. I was going to half-inch his idea but misremembered it under the influence of turning tides and Tribute.
However, my phone’s autocorrect was quite enthusiastic and fixed my draft title to “Corneal Streisand”. So, here we are a roundup of the various posts I’ve written since we got home with a few of my snaps (the full public gallery is on Flickr and a select few on Instagram).
St Martin’s Daymark – The daytime “lighthouse” with no light on St Martin’s Island, IOS, visible from mainland Cornwall and originally erected in 1683.
Manks Puffins – The reason the scientific name for the Manx Shearwater is Puffinus puffinus and not the Puffin, which is Fratercula arctica.
…actually, it was probably the 27th seal. We saw quite a few on a boat trip from Hugh Town on St Mary’s to the eastern isles of Scilly aboard Sea King skippered by Fraser Hicks. There were lots of adults and pups of the large species known as the grey, or Atlantic, seal (Alichoerus grypus, meaning “hooked-nosed sea pig”). Of course, seals are more closely related to otters and bears than pigs although their resemblance to dogs, and cats even, is often commented on. It’s evolutionary convergence, I believe, although otters and bears, cats, dogs and seals all share a common ancestor if you follow the branches of the family tree back far enough.
There are two sub-species of grey seal, A. g. atlantica (found on both sides of The Atlantic Ocean) and A. g. grypus (found in the Baltic Sea). However, the genetics suggests that the eastern and western Atlantic populations are distinct and have been for at least one million years, and so might also be seen as separate subspecies. The western Atlantic grey seals (or should that be gray seals?) are much bigger than members of the eastern population:
Western: Males grow up to 400 kg, females 250 kg.
Eastern: Males max out at ~310 kg and females ~190 kg.
They’re fascinating creatures and very photogenic. But, it’s with some sadness that among my photos from the trip is one of a seal pup with what looks like some nylon webbing from a crab pot entangled around its neck (see photo below). It looks as if the webbing has cut through the skin and blubber although there is no obvious bleeding, so presumably, the animal has been encumbered with this flotsam for quite some time. It is difficult to know whether it will survive into adulthood. We were in a boat with no possibility of getting close to the rocks to disentangle the animal. There were snorkellers in the water, but whether or not they could safely get to the animal is a moot point too.
We went on a pelagic trip in the Isles of Scilly with Sapphire skipper Joe Pender, departing Hugh Town harbour, St Mary’s Island on 9th July 2018 at about 5pm. Within seconds we were being tailed by dozens of Herring Gull.
Engines were cut about an hour out to sea and the anglers aboard began flicking their rods to catch mackerel, which they did, a dozen or so quite quickly. Then the fishing for Blue Shark (Prionace glauca) began. An 83-year old angler hauled in the first (with a little assistance from crew and fellow anglers to get lines around and from under the boat). The catch was a 2.3 metre specimen, it was photographed, scientifically tagged*, and returned to the waves largely unscathed, but perhaps a little confused. I must admit, you could almost see the fear in its eyes while they were doing the weights and measures and shoving the tag under its skin!
Blue Shark, Prionace glauca
The older birdwatchers aboard jeered some of the subsequent efforts. But, by the end of the fishing it was a draw, 6 landed, 6 that got away.
Anyway, the birdwatching, was not quite the numbers game we had hoped for, but aside from the dozens of Herring Gull, we saw lots of Gannet, many over the boat and a distant flock diving on a patch of water where dolphins were also feeding. We had a few Fulmar and about the same number of Manx Shearwater (aka Manks Puffins).
The skipper called out another bird as it crossed our stern and I snapped at it as quickly as I could. I didn’t catch what it was at the time, I thought I heard him shout “Manxie!”. But, back home and on dryland with my laptop I could see it was a Skua that I’d photographed. The Facebook bird ID group called it out – it’s a Bonxie – a Great Skua (Stercorarius skua). Bonxie is a Shetland name for the bird probably a word of Norse origin. Skuas are piratical birds, they will steal food from other birds. But, they’re also predatory, and the Great Skua is capable of killing a kittiwake. Stuart Keenan on that Bird ID group tells me he’s seen one in Wester Ross kill and eat a first-year Great Black-backed Gull! In the same Facebook thread, Mike Honeyman told me that the Bonxies used to have a fairly good crack at the warden team on Fetlar. “We were suitably nervous in their vicinity!” he writes.
So, the Great Skua, a lifer for me, even if I didn’t get a decent shot. I wasn’t quick enough to get a focus lock on this bird as it crossed the stern of our moving boat, when the skipper shouted. The subsequent photos were reasonably sharp as it flew away but underexposed against the bright evening sky as, again, I wasn’t quite quick enough to adjust.
*UPDATE: 2024. The scientific work is important even if a few sharks have to be hauled from the water to be tagged.
The Mediterranean Blue Shark, a species critical to the marine ecosystem, is facing the threat of extinction due to overfishing and a lack of proper conservation efforts. A 2024 study explored the genetic differences between specimens in the Mediterranean Sea and the Northeast Atlantic Ocean to understand if they are separate populations. The results showed subtle genetic differences, suggesting that the Mediterranean sharks are largely isolated from Atlantic populations. This separation means they rely on local populations for survival, with limited new sharks coming from the Atlantic.
This has important implications for conservation. Current management often treats Blue Sharks as a single population, but this overlooks the unique risks facing the Mediterranean sharks. Overfishing in this region could push them closer to extinction, especially since they reproduce slowly and are not being replenished from elsewhere. Protecting these sharks requires more targeted conservation strategies and international cooperation.
This research is vital not only for blue sharks but for understanding how fishing and environmental changes affect marine ecosystems as a whole. Safeguarding such apex predators is essential for maintaining the balance of marine life.
I don’t know if Pender’s tags are specifically part of the data for this particular study, but they do feed into the bigger picture of Blue Shark movements in the Atlantic.
There is a large red and white striped object on the Scilly isle of St Martin’s, you can’t miss it if you visit. It’s an obvious destination when hiking the island and a great attractor for a nice photo of the island from a boat. But, what is it?
Well, it’s a daymark…
…basically a daylight hours beacon for mariners.
The daymark on St Martin’s sits on its northeast corner and was erected in 1683 by Thomas Ekins, first steward of the Godophin Family to live on the islands. It is a rendered granite circular tower (4.8 metres in diameter and 6.4 m tall) with a conical top taking it to 11 m tall. It was originally painted white (until 1822). By 1833 it was being painted red but is now painted with red and white bands to make it more visible in any weather, you can see it from the Cornish mainland if the weather and light are right. The St Martin’s daymark is a Scheduled Ancient Monument.
The Manx Shearwater is a medium-sized shearwater in the seabird family Procellariidae, photo immediately below. The scientific name of this species is Puffinus puffinus. It’s a tautonym, which means the name repeats to indicate this species is the “type” for the family.
But, you’re perhaps wondering why isn’t it the Atlantic Puffin with its colourful beak the bird that gets to be called the “type” of the family instead of this largely black and white seabird. Well, the answer lies in the fact that Manx shearwaters were known as Manks Puffins in the 17th century. The word puffin has an Anglo-Norman etymology (in Middle English it’s pophyn) and it means “the cured carcasses of nestling shearwaters”, a delicacy at one time. So, back when animals were being given their scientific names and the science of taxonomy and its rules and regulations first being drafted by Carl Linnaeus, the Manx Puffin was the type and was given the appropriate name – Puffinus puffinus.
It is thought that the bird we commonly call the Atlantic Puffin today (Fratercula arctica) got its common name much later, perhaps simply because it has nesting habits similar to the Manx Shearwater.
We recently visited the Isles of Scilly (IOS), spent a few days island hopping from St Mary’s to Tresco, St Agnes and Gugh, St Martin’s, the Western Isles and Bishop Rock Lighthouse and the Eastern Isles. Given that Manx Shearwaters have started breeding here again we were hoping to see quite a few. I think in total we probably saw 20-30 over the course of the week whereas others had seen vast flocks of 1500-2000 the week before. Same applied to the Atlantic Puffins…we were there just a little bit too late in the season.
Meanwhile, we did take an evening pelagic (open-water) trip on a shark-fishing/bird-watching boat. The focus was very much the sharks for the fishermen at least.
The sea anglers caught six (another six got away). The first and largest was 2.3m from tip of its nose to the tip of its tale and was caught by an 83-year old gent with only a little assistance from crew and fellow anglers. All the sharks were scientifically tagged and returned to the water alive and flicking.
Our hope was to see a lot of Manx Shearwaters, like I said. I think we saw, at most three or four on that trip. We did see a lot of Gannets, Herring Gulls, several Fulmars, and a Great Skua.
However, perhaps a highlight was the appearance of a school of short-beaked dolphins (pictured below) accompanied by some bottle-nosed dolphins as we headed back to St Mary’s at sunset. The photo below is of Short Beaks skimming alongside our ferry back to the mainland rather than the low-light snaps I got of the various dolphins on the evening pelagic.
I’ve shared a gallery of my best bird photos from our IOS trip via a public link on Facebook and you can see the top 10% of all of our photos from the trip on Flickr.
There are lots of birds in the Isles of Scilly, although unfortunately, we were at the tail-end of the Puffin season. The islands had had good weather and Easterly winds for a while, which meant less marine bird activity and lower numbers. We saw Manx Shearwaters by the handful as opposed to flocks of 1500-2000 on pelagic trips the week before. Lots of Gannet meant dolphins: Bottlenosed and Common Dolphins on a couple of trips, and lots of seals on another. Oh, and a lone Red Squirrel, just to give the mammals a mention. We also saw six Blue Sharks being caught on our pelagic trip, measured, and scientifically tagged to be returned to the sea a little shaken but otherwise unharmed.
But, on the plus side, it meant no rain, blue skies and warm, sunny days. It was like being in The Caribbean.
We also added a few new species to the bird gallery on this trip: Manx Shearwater, Greenshank, Rock Pipit, Carrion Crow. Various juveniles: Dunnock, Linnet, Lapwing, Barn Swallow, and others. And, of course quite a few we had seen and photographed before, but in new locations: Puffin, Guillemot, Fulmar, Razorbill, Gannet, Great Black-backed Gull, Herring Gull, Lesser Black-backed Gull, Shelduck, Oystercatcher, Swallows, Wren, Reed Warbler, Stone Chat, Meadow Pipit, Peregrine. There were more House Sparrow here than anywhere we have ever visited but only the occasional Chaffinch, Greenfinch, Blue Tit, Great Tit, Song Thrush, Blackbird, Collared Dove, and other fairly common town and country birds.
Interestingly, someone told us on our island-hopping travels that Robins are rarely seen on the IoS, we saw at least four. Black-headed Gulls only rarely made an appearance. Birds we did NOT see at all that we normally see everywhere else in the UK: Buzzard, Kestrel, Jackdaw, Rook, Wood Pigeon, etc.
Our full IoS gallery of Birds, Boats, Mammals, and More is on Flickr and includes photos from Mr & Mrs Sciencebase. There’s also a bird-specific gallery on my Facebook, which should be visible to all visitors.
I bought a sack of black sunflower hearts to restock the garden bird feeders instead of that wasteful mixed seed most of which the small birds discard and the Woodpigeons and our labrador hoover up. It seems the Great Tit (Parus major) and the Blue Tit (Cyanistes caeruleus) are quite partial to these. They need some degree of patience to eat them given that the tasty seed is contained within an edible husk. This deters some less patient birds. I’ve not seen Starling (Sturnus vulgaris) tucking into these seeds on the feeders, for instance. They much prefer to snaffle suet balls and mixed dehusked seed mix.
Eating such seeds comes with the risk of greater exposure to predator threat while the bird cracks the seed open. The Great Tits seem to quickly duck in and out, grabbing a seed and then darting back into the foliage to presumably break it open and eat it. A female Greenfinch (Chloris chloris) didn’t seem perturbed, standing her ground (well, her perch) while she opened it to eat.
A few snaps from a recent, short, but sweet, and hot, camping trip to North Norfolk. Several Turtle Doves, one Cuckoo, lots of Whitethroat, Linnets, Swallows, Swifts, House Martins, several Sedge Warblers, Pied Wagtail, Wren, Common Tern, Dunlin, Knot, the usual gulls (Lesser Black-backed, Black-headed), Mallards, Moorhens, Coots, Avocet, Shelduck, Skylark, Kestrel, Greenfinch, Goldfinch, various geese (Canada, Egyptian, Greylag), Black-tailed Godwit (just one, overhead), and nesting Common Ringed Plover and Oystercatchers.
