Yet more woodpeckers

Back at the end of February I spotted a woodpecker high in a tree in our local woodland; great spotted woodpecker (Dendrocopos major). Of course, for me, woodpeckers are more often heard and not seen, the headbanging of this species and the mocking laughter of the green woodpecker or yaffle (Picus viridis). As the weeks went by there was more mocking laughter in the woods as if the yaffles were scoffing at the fact that I couldn’t get a shot at them. I caught one in flight elsewhere, but then gave up on trying to get a photo of greens having spotted a GSWP heading in and out of a high hole in a tree.

Eventually, I saw a chick, saw it grow, saw both parents (Dad with his red nape, Mother with her completely black and white upper body). Coming and going, bring caterpillars and beetles and taking away faecal sacs. Seems there was only one chick to nurture, whereas there are, it seems, usually half a dozen. Anyway, when it fledged, I missed the departure, but did see what looked like a mini-me GSWP a few days later. That was the end of May.

Now, a few weeks later, there’s a lot of noise in a different part of the woodland, holes in trees and the occasional sighting of a green woodpecker chick, and another out of the hole, and then the next morning three or four calling in yet another location. No adults seem to be around, although the books say they do continue to feed them for a couple of weeks after fledging. It’s intriguing. Where are the adults? Do they simply stay away until humans and canines are gone, but if they’re so shy, why do the chicks make such a lot of noise and remain fairly obvious in some of the trees?

The day-flying Cinnabar moth

The Cinnabar moth (Tyria jacobaeae) can be found throughout Britain, anywhere that its larval foodplants, ragwort and groundsel grow, except northern Scotland. Indeed, the species was introduced into New Zealand, Australia and North America to control poisonous ragwort.

The Cinnabar, flew to actinic light moth trap at night, surprisingly.

The moth is named for the red mineral cinnabar, mercury sulfide, because of the red patches on its predominantly black forewings and its hindwings , edged with black. Like many other brightly coloured moths, it is unpalatable to its would-be predators.

Top Ten Pop Cameo Appearances

There are plenty of actors who try their luck as musicians and lots of musicians who do the reverse. Some of them start out as wannabe actors and end up as musicians and vice verse. And, then there are those who just fancied a cameo appearance in a pop video for the lulz.

10 Christopher Walken dancing to Fat Boy Slim’s Weapon of Choice

9 Chevy Chase lip-syncing Paul Simon’s You can call me Al

8 Hugh Laurie reprising his Blackadder Prince Regent role for the Annie Lennox song Walking on Broken Glass although the premise looks a lot like the film – Dangerous Liaisons.

7 Actor Rupert Grint playing an Ed Sheeran doppelganger in the video for Sheeran’s song Lego House

6 Sacha Baron Cohen, in the guise of Ali G, as the driver/DJ in Madonna’s Music

5 Godfather Part II Actor Danny Aiello playing the father in Madonna’s Papa Don’t Preach

4 Actor Courteney Cox being invited to dance on stage with Bruce Springsteen in the video for Dancing in the Dark as if she were just some random member of the public at one of his concerts.

3 DJ (not an actor) John Peel pretending to play mandolin for Rod Stewart’s Top of the Pops appearance miming to Maggie May it was actually Geordie boy Ray Jackson from the band Lindisfarne who played the instrument on the record.

2 Composer Hans Zimmer in the video for The Buggles’ Video Killed the Radio Star. Of course, it was Geoff Downes who played keys on the recording, which interestingly was the second attempt by the team to have a hit, it having been released as a single earlier by co-writer Bruce Woolley with his band The Camera Club (Thomas Dolby on keyboards for that version, which brings us to our number one).

A quarter of a million gannets

As children, if my sister Sue and I were eating particularly enthusiastically, our Dad would often refer to us as a couple of gannets. I therefore grew up assuming that these seabirds were voracious consumers of sausage rolls and butterfly cakes. They’re not, obviously, their staple diet is fish and rather than eating like pigs, as it were, they are quite graceful divers who plunge into the sea to take their submarine prey.

The name gannet is derived from Old English ganot meaning “strong or masculine”, and that word in turns comes from the same Old Germanic root as our word for a male goose “gander”. Both male and female have some interesting adaptations for their seafood diet. Primarily, they do not possess external nostrils. Instead their nostrils are inside the mouth. Secondly their face and chest is lined with air sacs that act like bubble wrap to cushion the impact when they dive into the water. Their quite prominent eyes are positioned well forward on the face for binocular vision, which allows them to judge distances accurately.

I suspect that the lenses in their eyes either correct for refraction across the air-water boundary or else their brains carry a neural network that calculates the necessary correction as they dive into the water so that they know where the fish they’re targeting actually are rather than where they appear to be from the bird’s eye view in the air above.

The birds photographed here are just a few of the quarter of a million or more nesting on the beautiful but smelly and noisy Bempton Cliffs on the North Sea coast of the East Riding of Yorkshire, England.

Northern marsh orchid, Dactylorhiza purpurella

When visiting RSPB Bempton Cliffs on the coast of the East Riding of Yorkshire to see the puffins, gannets, razorbills, guillemots and kittiwakes, don’t miss sight of the northern marsh orchid, Dactylorhiza purpurella.

According to the Kew Gardens website:

Northern marsh orchid occurs throughout the northwestern part of Europe. It is found in southwestern Norway, southern Sweden, Denmark (including the Faroe Islands) and the UK. In the UK it is widespread in northern England, Northern Ireland, Scotland (including the Shetland Islands) and Wales. It is found at up to 600 metres above sea level.

Don’t call Saul, call Dexter

The forensic luminol blood test familiar to CSI and Dexter fans alike can be used to illuminate blood stains. It uses peroxide which reacts with the iron in haemoglobin. However, 20+ years ago scientists realised that the same test could be used to detect peroxides too. Indeed, researchers worked out that they could use the luminol test to prove that a pharmaeutical product claiming to contain the antimalarial drug artemesinin (a natural peroxide) actually contained this drug and so help avoid pharma fraud.
 
Now, a team in China has turned that idea on its head and are using the antimalarial drug itself to give the luminol test a 100,000 times sensitive boost that also makes it more specific to identifying blood stains and distinguishing them from other dark stains one might find at a crime scene investigation. Better call Dexter…
 
My latest news story on this work appears in the magazine Chemistry World.

The turring, purring turtle dove

UPDATE: The purring call of the male Turtle Dove was in halcyon days of yore very much the sound of the English summer, long before the Collared Dove arrived on these shores around the time of World War II.

It was with great pleasure that summer of 2018, we’ve been places where we’ve heard several. Dog walking in Rampton, Cottenham (South Cambs), and camping in Snettisham (North Norfolk). There were at least three not far from where we pitched our tent.

I should perhaps have saved this bird for the Christmas edition given its pride of place in the “The Twelve Days of Christmas” the familiar gift accumulation song of 1780, thought to be French in origin that has the generous benefactor donating “two turtle doves” to their true love along with various leaping lords, pipers, milkmaids, drummers and of course a partridge in a pear tree.

I’m afraid I’ve only got one turtle dove (Streptopelia turtur) to give you anyway. This specimen had turned up on the day we visited RSPB Bempton Cliffs in June 2017 to see the puffins, gannets, guillemots, razorbills and others that live on the cliffs there. It was ground feeding among the jackdaws, chestnut-capped tree sparrows (Passer montanus), the more familiar, yet not native, collared doves, a pair of greenfinches (Chloris chloris), and a large brown rat (Rattus norvegicus) at the feeding stations close to the visitor centre.

The name of this bird comes from the Old English turtle, from the Latin turtur which is onomatopoeic given the bird’s purring call, trrr-trrr-trrrrr (as opposed to the more staccato coo-coo-coooh of the collared dove). The RSPB describes the turtle dove’s call as a “gentle purr…an evocative sound of summer”. However, it is not so often heard these days because of declining numbers, due to more efficient farming practices and a lack of wildflower seed and grain during its breeding season, habitat loss both here and in its wintering grounds. There’s also the issue of their being hunted in their millions on passage across Europe.

As such, the species is on the Red List of conservation concern. The RSPB offers farmers advice on encouraging this rare species here.

Bridled guillemot

TL:DR – The bridled guillemot is a polymorphism (not a sub-species) of the Common Guillemot (Uria aalge) found in the North Atlantic region.


Guillemot is the common name for various auk-type seabirds (Charadriiformes). In the UK, there are two genera commonly seen: Uria and Cepphus. Common Murre, also known as the Common Guillemot (Uria aalge) is a large auk with circumpolar distribution. It spends most of its time at sea. It breeds on rocky cliff shores or islands. The Bridled Guillemot is a polymorphism of the species found in the North Atlantic region.

My photo shows a Guillemot at RSPB Bempton Cliffs on the coast of the East Riding of Yorkshire. If I told you that there is a species of guillemot known as the spectacled guillemot, you might imagine that this is she. However, this is actually a bridled guillemot. It’s not a distinct species but a genetic polymorphism of Uria aalge, the common guillemot (aka the common murre). This strain has thin white circles around its eyes that stretch back as a thin white line. By contrast the spectacled guillemot is rather distinct looking and has thick white circling around its eyes and no “bridle” and is Cepphus carbo.

Bempton Puffin

It’s a couple of years ago that we last walked the clifftops along the East Yorkshire coast of the Wolds spotting gannets, guillemots, razorbills, kittiwakes, and, of course, puffins. The day we arrived coincidentally, RSPB Bempton Cliffs had featured on BBC Springwatch because they were opening their new visitor centre. It’s all well heeled in now and armed with the Sigma, I thought it was time I got some new shots of the seabirds.

First up, everyone’s colourful favourite the Atlantic, or common, puffin (Fratercula arctica). There were a few around but not nearly as many as we’d hoped and I don’t think we saw any chicks. Certainly didn’t see any with food in their mouths for the RSPB’s competitive hashtag, #ProjectPuffinUK. Here’s the shot that was closest I got to one.

The common puffin is an auk, the only puffin native to the Atlantic Ocean, breeding in Iceland, Norway, Greenland, Newfoundland, and many North Atlantic islands, and as far south as Maine in the west and the British Isles in the east. Although it has a large population and a wide range numbers have declined rapidly recently in some parts of its range it is rated “vulnerable” by the IUCN. It swims on on the surface of the sea and dives to feed on small fish.

Oats and beans and barley grow

The local fields of barley are, wave-upon-wave, like an opalescent green sea in the wind today, shimmering and shifting and stretching across the Fens. The barn swallows are reeling overhead and the skylarks are riding their aerial elevators up and down, tuning their on-board radios to their sweet Caroline in the fields below. And, then, there is this feathered friend.

Last time I posted a photo of a bird I thought was a corn bunting (Emberiza calandra) it turned out to be a linnet (Linaria cannabina) that wasn’t quite in full blush. However, this bird flitting around the barley field, ducking in and out of the wavering stems, then up again, swirling left and right, and from the nearside to the middle distance repeatedly is surely a bunting. In its manouevres, I presume the bird was pretending to land on the nest to distract me, the predator with the big glass eye. It would then wheel off to another spot and back and forth again and again. Or, maybe it was simply catching airborne prey and ducking down to deposit at chick central.

Although I was in plain sight, it chose at one point to settle itself, indeed verily perched itself on some vegetation atop the dyke, for a quick sing-song. It couldn’t have been any more visible if it had actually landed on my camera and asked for a bravo. To top it all, it threw its head up, beak wide open and sang across the barley. Anyway, it is a corn bunting.

Corn buntings are scientifically speaking Emberiza calandra but they’re also sometimes referred to as Miliaria calandra. The “calandra” is from the ancient Greek: calandra lark. Emberiza is old German, Embritz, a bunting. Although “ammer” is modern German for a bunting, as in the yellowhammer (Emberiza citrinella).

The RSPB website uses E calandra, but the RSPB Handbook of British Birds (4th edn, 2014) (currently free with a new membership) uses M calandra
