NWT Barton Broad

Heading home from a camping trip in North Norfolk, we had vague plans to visit an RSPB reserve in the area but sidled up to the second largest of the broads, Barton Broad in Barton Turf. The broad was apparently only accessible by boat until 2003 (when a boardwalk was piled and constructed to get you to a viewing platform) and is alleged to have been a splashing ground of local boy Horatio Nelson. It was acquired by Norfolk Wildlife Trust in 1945.

From the viewing platform in late August 2017, cormorants winging it on pontoons, lots of great crested grebes and a few gulls, roach with their red fins in the water, but more intriguing a couple of swallowtail caterpillars on the milk parsley readying themselves for pupation at the foot of the reeds where they will overwinter and emerge next Spring.

Also sighted a couple of reed warblers and various dragonflies, and an orange flower that seemed quite whitespread in the darkest recesses of the area surrounded by the Herons’ Carr Boardwalk, Facebook friends identified it as an invasive species, orange jewelweed (Impatiens capensis).

Earlier in the trip sandmartins and lots of cormorants on the North Norfolk coast, at least one meadow pipit with a mouthful of crickets and dragonflies and an exotic-looking sycamore moth caterpillar in the less exotic Mundesley car park, oh, and a somewhat exotic alpaca farm (all females, apparently).

Moving housemartins – Delichon urbica

Swifts, swallows, and housemartins (Delichon urbica) never seem to stop their flight once they arrive at our shores in the spring. Today, there was a whole flock of housemartins gathering on overhead wires in Aldreth, Cambridgeshire, to preen and perhaps make their plans for the long and perillous return journey to sub-Saharan Africa. Their summer of breeding and feeding in the British Isles and the European mainland nearing an end.

Wake up Maggie!

Apparently, magpies (Pica pica) are invoked in Christian allegory because they look like a composite of a white dove and a black raven…they were alleged to have perched on the prow of The Ark during the Biblical flood and to have cackled and laughed whilst the world drowned…

Then there’s the nursery rhyme, made famous for British children of the 1970s by the ITV rival to Blue Peter, Magpie. The theme tune for the show perhaps usurped earlier, traditional versions of the nursery rhyme from our collective psyche.

One for sorrow,
Two for joy,
Three for a girl,
Four for a boy,
Five for silver,
Six for gold,
Seven for a secret,
Never to be told.
Eight for a wish,
Nine for a kiss,
Ten for a bird,
You must not miss.

There are versions that begin:

One for sorrow,
Two for mirth,
Three for a funeral
And four for birth

and

One for sorrow,
Two for mirth
Three for a funeral,
Four for birth
Five for heaven
Six for hell
Seven for the devil, his own self

Why the magpie gets such a raw deal in mythology and folkore is perhaps down to the sound it makes, the cackling laughter, and perhaps also because it ties together white and black, day and night, good and bad, light and shade…either way it’s just a bird, a corvid, or crow, albeit a clever one.

Prisma – the goose that lays golden photos

I tried the Prisma app when it first launched, a year or so ago, but then quickly forgot about it. A few friends have been playing with the app recently though and producing some nice filtered photos, so I thought I’d have another play. I picked a recent closeup of a greylag gosling I snapped in Milton Country Park north of Cambridge.

It seemed to be the perfect sort of shot to apply the various mosaics and filters that go by the quite esoteric names of Thota Vaikuntam, Wave (Hokusai-like), Mononoke, Mondrian, Femme (Picasso-like), The Scream (Munch-like), Roy (Lichtenstein-like), Heisenberg (ink sketch) etc. Top left in the contact sheet is my original photo, the others are various Prisma treatments picked to taste from the first few and applied with 100% of the processed image showing rather than blending with the original

Although this is a mobile app I ran an Android emulator known as Blue Stacks on my Windows 10 desktop machine and loaded the app in that to make it easier to pick and choose and to save files rather than messing around with the tiny mobile phone screen and shuttling files using the cloud. Montage was made with “paint.net” and my “dB” logo applied, as ever with Paintshop Pro. having mentioned a hack for uploading photos to Instagram from a Windows desktop machine, Blue Stacks is another alternative, run Instagram as an app within BlueStacks.

The Heisenberg filter, emulates an ink pen sketch and is styled for that TV programme, Breaking Bad

Green flash at sunset

If you’re watching a sunset or a sunrise, occasionally you might see a green flash or green rays from the edge of the sun just as it disappears from view or begins to peek over the horizon. This a purely atmospheric, optical phenomenon, nothing to do with surface activity on the sun. By pure chance I seem to have caught a bit whilst photographing a sunset on the North Norfolk coast recently (one of the only places in the UK where, in the middle of summer, the sun both rises and sets over the sea on the “east coast”. I don’t remember noticing the green flash whilst taking the photos, it’s only now in scanning through the files that I spotted it.

Earthsky has as interesting explanation of the phenomenon:

The green flash is the result of looking at the sun through a greater and greater thickness of atmosphere as you look lower and lower in the sky. Water vapor in the atmosphere absorbs the yellow and orange colors in white sunlight, and air molecules scatter the violet light. That leaves the red and blue-green light to travel directly toward you. Near the horizon, the sun's light is highly bent or refracted. It's as though there are two suns — a red one and a blue-green one — partially covering each other. The red one is always closest to the horizon, so when it sets or before it rises, you see only the blue-green disk — the green flash.

Cottenham War Memorial – A fishy tale

UPDATE: It’s definitely not a dolphin in Cottenham.

Who else has noticed the large “fish” leaning head down against the back of the legs of the serviceman featured in Cottenham’s War Memorial? Friend of the blog Patrick Coughlan certainly has and he wonders what it’s all about..

According to one web site it perhaps alludes to the designer’s naval past. However, another suggests that it’s not a fish, but a dolphin, a mammal frequently associated with the Grey Funnel Line (the Royal Navy) and marine regiments. Indeed, Cottenham’s war memorial is similar to the one in St John’s Churchyard, Stokesay, Shropshire, which has a large dolphin at the serviceman’s back. Locals there say it is indeed an allusion to the sea but perhaps also to the mythology of dolphins bearing dead heroes in the afterlife.

How to Instagram photos from your PC

UPDATE: If you don’t want to or cannot use the hack described below, then simply install a plugin or browser extension that acts as a user-agent switcher. Such an extension basically lets your browser pretend it is an Android phone, an iPhone or indeed any other type of browser. I tried uploading to Instagram with this user-agent switcher extension installed under Chrome and it seemed to work fine.

You have been able to access your Instagram account from a desktop browser for quite some time but you cannot post a photo without a workaround. The workaround is quite straightforward. You simply log into Instagram on your desktop browser, switch to developer mode (right-click “inspect” in Chrome) and choose a mobile device view. Full instructions are here.

I just tried it successfully with my recent kingfisher photo…seems to have worked. Saves me having Instagram running on my phone as it drains the battery really quickly even with the app supposedly “inactive”.

Developer or “inspect” mode in Chrome lets you make your browser look like it’s a mobile browser running on a Galaxy, Nexus, iPhone, iPad etc. If you want to see what a site looks like (perhaps testing your own for instance), this is a useful tool. I’m sure there are mobile only sites out there that people use, this is a workaround for that too, so you don’t have to use an actual mobile device. (I assume it’s simply doing a user-agent switch within the dev mode, which reverts to normal browser when close the dev window). It’s a tiny bit more complicated for Safari on a Mac, but the instructions are in the link.

Don’t miss the beauty of the kingfisher

The common kingfisher (Alcedo atthis) I wrote about earlier in the year seems not to have taken up long-term residence where I photographed a female in January 2017. Mrs Sciencebase and myself saw others at WWT Welney, as one might expect. But despite watching and occasionally searching, even at a local nature site called Kingfisher Bridge, we didn’t see another until a trip to the National Trust site at Wicken Fen.

Common kingfisher

Over the pond at the Roger Clarke hide there was a family – male, female and three fledglings. Mrs Sciencebase saw all five while I was staring through a zoom lens and photographing the male who alighted on a branch very close to the hide.

I was hoping to find a current piece of scientific research about kingfishers to share. There was something last year about the kingfisher and other piscivores and tracking the foods they eat, but that wasn’t as interesting as scientific research that suggests that “kingfishers prey upon the most accessible types of prey.” Not quite the earth-shattering breakthrough I was hoping for, basically tells us that kingfishers minimize their energy expenditure when foraging…well, don’t we all?

The common kingfisher’s scientific binomial (the monicker most people call an animal’s “Latin name”) is Alcedo atthis. The word Alcedo is indeed Latin for kingfisher and is derived from the Greek word for kingfisher “halcyon”.

Atthis was the name of a beautiful young woman who in mythology lived on Lesbos and was a favourite of Saphos.

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.
