Tyne Valley Birding

A bit of social distancing, walking, and birding in the Tyne Valley:

Birds seen during a couple of days of walking up and down each bank of the river:

Blackbird, Bullfinch, Buzzard, Chaffinch, Chiff Chaff (heard), Collared Dove, Cormorant,  Crow (Carrion),  Dove (Stock), Dunnock, Fieldfare, Goldcrest (heard), Goldfinch, Goosander, Gulls – Black headed, Herring, Lesser Black-backed, Heron, Jackdaw, Jay, Kestrel, Kittiwakes, Magpie, Mallard, Oystercatcher, Redwing, Robin, Rook, Swan – Mute and Whooper, Tit – Blue , Coal, Great – Wagtail – Gray and Pied – Wood pigeon, Wren, Yellowhammer.

Final morning along the river in Newcastle itself observing the Kittiwakes that nest and breed on the Tyne Bridge itself, this is essentially an inland colony, and uniquely nesting that fathest inland of any colony of this species anywhere in the world.

Sizewell and Suffolk

TL:DR – One of the natural side effects of planting a nuclear power station on the coast.


This platform was one of two “water rigs” one of which was used to draw cold seawater into Sizewell A nuclear power station; two magnox reactors operated there from 1966 to 2006. The spent “coolant” having generated its superheated steam to drive the turbines to drive the generators was then released back into the sea at the second platform, the one closer to the shore, pictured below.

Because the discharged water was at a slightly higher temperature than the sea, an oceanic microclimate formed here, which led to greater numbers of fish and birds utilising the thermal boom.

Most of the machinery and components were removed during decommissioning of the reactor, but birds such as Cormorants and numerous gull species still find the platforms useful as roosting sites. There was a time when Kittiwakes nested on the platforms, their presence led to delays in removing hazardous components during decommissioning. Ultimately, these two platforms will be removed. Shipping buoys are already in place to warn of sandbanks along this stretch of coast, so the platforms no longer have warning lights for that purpose as they once did.

Sizewell B, which you would recognise as the big white dome is a pressurised water reactor; the only commercial PWR in the UK. Sizewell C is on hold until “issues” and “concerns” are resolved. One can imagine that palms will be greased at some point and the public protest against it will be forgotten by all but those who live in the area.

Incidentally, fans of musician Thomas Dolby will likely know Sizewell A as the setting of his music video for the song Europa and The Pirate Twins.

Sparrow names – Nicknames and slang for House Sparrows

TL:DR – There are lots of regional slang names for the House Sparrow.


Do you have a local word for Passer domesticus, the House Sparrow? Where I grew up in the North East of England we called them Spuggies, I hear from a Shropshire lad that it’s a common nickname for this species in that part of the country too. They’re also sometimes simply called spugs in Northern England. In the South P. domesticus is known as a sparr, sparrer (or Cockney sparrar), spadger (Northern Ireland too), spadgick, and phip or philip. That latter one is intriguing.

In Scotland, they’re often known as a spur or sprig (also Spriggies after a Mr Sprigg, apparently, that sounds unlikely given spriggies sounds like a dialact variation on spuggies). One contact on twitter (hahah!) said that his father who grew up in North Lanarkshire called them speugs, pronounced “spee-ugs”.

It’s very difficult to discern the etymology of these nicknames some sources cite spadger as originating in Leeds in the North rather than the South of England. But just as nicknames for games and people often arise with -er on the end. Bradders, was an occasional nickname for me as a bairn (child). Soccer is short for association football as Rugger is short for Rugby Football. Sparrow perhaps became sparrah, spugger, spuggie…

The same species is often called an English Sparrow in North America where its nicknames are commonly spatzie or spotsie, from the German Spatz. Australians might know the immigrant species as a Spag or Spoggie. And, perhaps less common Sprog or Sproggy and even spridgy or spudgy.

There are others: spyng, spurdie (from The Orkneys), chummy, craff, hoosie, row-dow, thatch sparrow, tile sparrow, and eave sparrow. (Cited here).

In Dutch, the species is known as a mus, or more specifically huismus, but that’s the official common name not a nickname. Spatz in German.

Reader Steve E emailed to tell us that in East London sparrows are often known as squidgers.

I must be going batty

Two Pipistrelle Bats flying around the corner of a pasture field at the edge of Rampton Spinney at lunchtime today. Pipistrelle comes from the Latin word for bat, which is vespertilio, which literally means evening bird (as in “vespers”). We usually two to three Pipistrelles circulating in our back garden on balmy, calm summer evenings. Each bat can eat up to 3000 flying insects every night, including moths…

Not seen a bat flying in broad daylight, except in a church, when it was presumably disturbed from its roost on a day we climbed the bell tower (with permission).

I tried to get a decent photo, but they’re fast-moving creatures and this is the best I could do of either of the pair even when they were flying overhead:

Of course, it’s winter and these two really ought to be tucked up in crevices in old trees, hibernating through the cold period. But, it’s been relatively warm this winter with perhaps only one or two mornings with a frost. Inordinately, warm weather and something that disturbed them may have brought them out of their self-imposed torpor early.

How emerging viruses jump from species to species

David Bradley reporting from the Royal Society, January 2004

The list of emergent viruses continues to grow. In the early 1990s, there was HIV, ebola, lassa, and others, almost all having jumped from their natural host species to humans. More recently, hepatitis C, Sin Nombre, West Nile, and of course SARS emerged. The common factor, said Dr Eddie Holmes of the University of Oxford, is that they use RNA rather than DNA to carry their genetic code.

Holmes believes that the genetics of our immune systems and viral genetics should be an equally important research focus. To infect a new species, an emerging virus has to overcome the new host’s immune system and to replicate in its cells, the success of which depends on both viral and host genetics and other factors.

But, Holmes asked, why do such pathogens emerge and what controls the emergence? Ecological change, as emphasized in Tony McMichael’s talk, is the governing factor – change in human proximity and change in host-species population density. The key to understanding lies in the fact that RNA viruses mutate a million times more rapidly than organisms with DNA. This endows them with great adaptability. On the other hand, a high mutation rate constrains viral evolution by capping the viral genome’s size, which limits adaptability. Higher mutation rates, after all, mean more chance of error in the viral genes. This “error-threshold”, explained Holmes, means that if a virus has to evolve a lot to jump between species then it is more likely to fail. We eat a multitude of plant viruses every day but no one has yet fallen prey to turnip mosaic virus.

The coronaviruses such as SARS, are different. They have a much bigger genome than other RNA viruses, which means that SARS and its relatives should evolve more slowly but their larger genome gives them greater adaptability. A better understanding of the constraints to RNA virus evolution will allow us to make better predictions about the emergence of new viruses and help us find improved therapeutic procedures. Rather than thinking about what RNA viruses can do, we should concentrate on their limitations.

Wilding our gardens with Seedball

A nice big package has arrived from the lovely people at Seedball. As I mentioned previously I am hoping to wild two patches of our front and back gardens to provide a couple of localised ecosystems for invertebrates, such as bees, butterflies, and moths and also to invest in those for the sake of the bats and birds.

Indeed, the various mixes that have arrived after discussions with Seedball are their bee mix, butterfly mix, shade mix, and a bat mix. Each has a wonderful mix wildflower seeds in their clay seed ball system that one simply spreads over the surface of a roughly prepared patch of soil (or in tubs). The balls have added nutrients and even some chilli powder to keep pests of them until the seeds have germinated.

I will be taking up turves from the lawns over the next couple of weeks (some of it will be used to make some dividing footways for #AllotmentLife. The remainder will be used to create some mounds behind at least one wilded area of the garden to add a bit of three-dimensionality to an otherwise flat and featureless garden. However, as with last year’s parallel project to the allotment we have #Pondlife and those plans were all a bit ad hoc and improvised when I pulled on my wellies and started doing the work. Thankfully, it seems to have worked, plants in the pond are growing, there are lots of snails, and we definitely have frogs using it as well as birds drinking from it.

The Bee Mix contains Seedballs to grow: Foxglove, Viper’s Bugloss, Birdsfoot Trefoil, Wild Marjoram, and Red Clover

The Butterfly Mix contains: Forget-me-not, Red Campion, Yarrow, Purple Loosestrife, and Musk Mallow

The Shade Mix has: Forget-me-not, Red Campion, Meadowsweet, Bellflower, Oxeye Daisy, Ragged Robin, and Meadow Buttercup

The Bat Mix contains: Evening Primrose, Cornflower, Corn Marigold, Borage, Wallflower, and Night-scented Stock.

A skein for a friend – a truly wild goose chase

In Stephen Rutt’s second book, Wintering, we follow him on a journey around the British Isles to find the elusive species and sub-species of what might at first light seem a rather dull and innocuous class of birds, the geese. The geese, you say? As in “what’s sauce for the goose is sauce for the gander”? What could be more interesting?

Well, hang fire, Rutt’s tale takes back through mediaeval droves to the ancient Greeks and the ancient Egyptians even, by way of the marshlands and reedy wetlands of Suffolk, Northumberland, and the wide rivers of the Scottish borderlands. It also takes us back and forth across oceans to Scandinavia for the geese have been with us a long, long time and are an integral part of British history in ways you cannot imagine, they are in historical festive diet, and embedded in our folklore.

Rutt’s poetic prose tells tale of Beans and Barnacles, of Canada, and Brent and Brant. He talks of Pink-foots of Greylags, and White-fronts. He writes with an empathy and an enthusiasm that has grown in him and grows in us the reader with each waft of the figurative quill. It’s a tale of chasing, of tracking, of falling in love with place and nature. A tale of missed opportunity and the luckiest of finds.

Wilding our gardens

In 2019, I reinstated our pond, well, a half-size version of the original that I filled when we moved to this house in the late ’90s with small children. The plants, water snails, and frogs thrived, it seems, the birds love it for a drink too, although, I did find a dead Goldfinch in there one day in the summer (victim of a neighbour’s cat, I think).

I also did some wilding of the gardens, front and back, with various seedlings (from RSPB Hope Farm), some packet seeds, and some Seedballs, which I blogged about at the time. I have masses of seeds collected to use this spring, including ones from some wildflowers that were not there deliberately but sprang up and were very attractive to some moth species.

This year, I am going to work with the good people from Seedball to cover a bigger area of the gardens with wildflowers. They have offered me various mixes and hopefully, there will be plants perfect for shade, some that will pull in the honey crowd (bees), and, of course, some for the Lepidoptera. I am hoping for great things from our garden this year, having ticked more than 300 species of Lepidoptera last year, I think that number might be exceeded quickly the more wildflowers.

The wilding of our gardens will benefit the birds, the amphibia, and the invertebrates species, hopefully, and make our small patch a little haven on the edge of farmland here in South Cambridgeshire.

Photographing the Andromeda Galaxy

That blurry smudge in the middle of my photo? I think…I think…that’s the Andromeda Galaxy. It’s the most distant object humans can see with their unaided eyes. Here, we’re aided, zoomed in quite a lot. There’s blur due to camera shake, unfortunately, or is an 8-second exposure too much to not get star trails with a 150 mm zoom…

If it’s not Andromeda I’d like to know what it actually is as it was definitely a barely visible smudge in the sky away from the big “arrowhead” of Cassiopeia and in a line from Mirach and Mu Andromedae in the constellation of Pegasus.

Owl spotting

Short-eared Owl at Burwell Fen, photographed mid-January

One evening in late November, I was once again, hoping to catch sight of the Starling murmurations that occur over the Broad Lane balancing pond. As mentioned in a previous, issue the local Starlings and their continental counterparts will often roost in the reed bed there, last winter there were literally thousands. At the time of writing, just a few hundred are roosting, but that can change on a wind as arrivals from Europe turn up when the weather changes. Anyway, reader Alison waved as she passed the pond on her dog walk. I later heard that she’d seen a scuffle between a Kestrel and a Barn Owl close to the Fen Bridge. Typical, I thought, for me to miss the avian action.

Anyway, there are quite a few barn owls to be seen on the outskirts of the village. These dusk hunters of silent flight will range along the Cottenham Lode (a fenland drain), across rough fields, and alongside roads. Often you will see a ghostly Barn Owl sidle up alongside hoping to home in on voles and other small rodents turfed out of the undergrowth by the rumbling of tires, even on the fresh tarmac of Beach Road.

There are other owls around; while videoing a starling murmuration over Rampton, I could see a Barn Owl in the field, but could hear a little owl in the hedge in which the starlings were hoping to roost. There was little chance that they would settle until the owls had departed, which eventually they did. The whole point of the murmuration, aside from the socialising, is to reduce the risk to the individual bird of being picked off by a bird of prey, such as a peregrine falcon, or perhaps an owl. The Little Owl is not a native species, it was introduced to the British Isles in the nineteenth century.

Rescued Tawny Owl at Fen Edge Festival 2019

Meanwhile, there are places around the village, such as The Green where there are tawny owls to be heard, and if you’re very lucky and keen-eyed, perhaps even seen. Like the Barn Owl the Tawny Owl has very dark eyes, which help it see even in low light, and coupled with its excellent directional hearing make it a mean night hunter. Tawnies pair up from about the age of one year and stick together, monogamously. Famously, their call – the stereotypical “too-wit, woo-ooh” is two birds calling almost in the style of Nelson Eddy and Jeanette MacDonald. The female calls “too-wit” and the male responds by wooing her.

Birders and Short-eared Owl

There are a few Long-eared Owls across East Anglia and the East Midlands although numbers are greater further north. Some readers may have been lucky to catch a glimpse of a vagrant Snowy Owl on the north Norfolk coast at RSPB Snettisham in March 2018. You have a greater chance of seeing the Short-eared Owl, however. This migratory species flies in from Scandinavia, Russia, Iceland, and we are lucky enough to have a patch of land not too far away where they can be seen hunting at dusk. Last winter, half a dozen or so “shorties” were often seen hunting at NT Burwell Fen and Tubney Fen, which are accessible by road from Burwell or on foot or cycling from Wicken Fen.

One of last winter’s shorties suffered a wing injury, and spent the summer on the Fen; it can still fly well, but presumably it felt that a trip back to the Steppes was not on the cards. As I write, this I have visited the fen twice this winter to see the shorties and reckon that there are four or so present. The numbers may have risen by the time you read this in early February. But, if you are reading it later in the year, beyond March, early April, you will have probably missed the chance to see them until next winter. Birding is very much about chance, timing, weather, and plain-old luck.
