Down by the Sea

A steaming hot Saturday. The hordes, having disgorged themselves in a swarm onto the seafront beach earlier in the day, have mostly departed, save the few that have stayed into the evening, tingeing the air with the smell of drifting barbecue smoke. The sea has departed too, receding far out to its low-tide mark. Apart from the gulls scattered across the expanse of mud left by the falling tide, there is little for the naturalist to find on this emptying beach that just a few hours ago bustled with people. Or is there?

The twist at the end of the opening paragraph was, I am sure, not very much of a surprise, or else why would I be bothering to write about it. Of course there are things to be found. The upper shore is in places covered with edible periwinkle, a few of their still sliding slowly over the wet mud. There are oysters, their pair of shells locked firmly shut, in a joining reminiscent of ‘smiling’ humpback whale. And of course, everywhere there are to be seen the little, coiled heaps of mud left by burrowing lugworms.

But, these aside, there is still the unexpected. On a stone my eye catches the oval shape of a chiton. These are marine molluscs with a trick borrowed from the Crustacea (or should that be the other way round?). The ‘shell’ is in fact eight overlapping plates that allow the animal to curl up in a protective, woodlouse-like ball if ever dislodged and swept away by a wave. It is this that earns them the alternative name of coat-of-mail shells.

A chiton – probably Lepidochitona cinereus

This is a sheltered, muddy shore, with nothing by way of rocks and their pools, yet I still discover sea anemones, animals we may be far less inclined to associate with sand and mud. It is one Sagartia troglodytes, a species that, rather than adhering to solid stone, is content to feed partially buried in the mud or sand. I watch this little creature fascinated, as it slowly ripples its mass of tentacles, filtering out foodstuffs in barely a centimetre of water.

The evening edges into dusk and I leave the beach a little quieter than I found it.

On the loquacity of the starling

Various Leavings

Outside my door I sometimes find

A curlew gargling in some

Marshy corner I can’t quite see.

Or a woodpecker exchanging trees

For telegraph poles.

Or a time-machine and listening

For a World War bomb

Plummeting to earth.

Or just a starling splattering

Guano on the bonnet of my car.

Birdwatching

I have just got in from some of the best birdwatching I have done in ages!

‘Where?’ you may well be asking. Well, given that I am self-isolating due to someone at work registering a positive Covid test and that this demands the mildly frustrating, but necessary requirement of not leaving home, the ‘where?’ in question is no less than my back garden. My garden is small, but I love it and feel privileged to have it at my disposal, something very much not to be taken for granted.

And what of the birds, that comprised this ornithological extravaganza of which I am presently to enthuse over? Well, there were quite a few starling and number of woodpigeon; a pair of robin; a great tit, blue tit and magpie; a little wren that stopped by for a minute or two and a couple of house sparrow up in the cherry tree where a blackbird sang. Oh, and a there was a lesser black-backed gull that slid soundlessly by overhead.

Now, perhaps to the disappointment of any self-confessed, serious birders that may have found their way here, this is not exactly a thrilling list of species. Even so, I have today whiled away a couple of hours in the spring sunshine watching them, without any thought of wanting to see anything else.

The Robin

I was out with a sketchbook, with hope of snatching some glimpses of the comings and goings of life in the garden. My endeavours as an ‘artist’ (very important inverted commas, those two) could best be described as nascent, the fruits of which are not of any great pertinence here. Rather it is the act of doing it. The alteration of perspective, subtle though it may be, necessary if one is to have any hope of capturing the subject on a page, that can give a refreshed view of the most familiar components of the world immediately around us, be they expressed by the plumply ruffled feather of preening pigeon, the ragged splendour of a sun-glossed starling or the simply wonder of a blackbird in song.

It is a good thing, I think, to every once in a while ground ourselves in such a way – by whatever means we choose – to help ensure that our sense of value of the natural world might be better aligned; to not take for granted the every day.

The endeavours of early spring

The warm days have encouraged something of a flush of insect life out into the open. The real surge of life is yet to come, but those more hardy, more adventurous early risers have brought a noticeable buzz of activity into the quieter corners of our green places.

A few species of mining-bee habitually emerge early in the spring. The conspicuously ginger-haired tawny mining bee (Andrena fulva) is one, a frequenter of gardens and the excavators of the little ‘volcanoes’ of soil that might appear in the lawn. These are the ‘mine’ entrances whose passages lead to a cell (or cells) into which these solitary bees deposit an egg.

It was not the tawny that I discovered in the woods yesterday, but another early species, Clarke’s mining bee (Andrena clarkella). I noticed the honey bee-sized insect buzzing deliberately about the face of a bank of bare soil. The pollen brushes on her hind legs were laden with a mixture of pollen and honey that she will place in one of the subterranean cells on top of which she will lay an egg. She had already dug out her burrow and I watched (and photographed) as she settled, having seemingly satisfied herself that it was safe to enter, before proceeding to dig her way into the finely worked soil of her previous labours and disappear from view.

It might have been that her neighbour, having stocked one of her own cells or perhaps just completed her excavations and now ready to go foraging, was waiting for me to move off before heading out…

With cold weather set to return, their promptness may be just as well.

Spring, simply

The Comma (Polygonia c-album)

My first butterfly of the spring this year was a comma. In some years it might be a brimstone, occasionally a peacock or red admiral, but often it seems to be a comma. It was sunning itself along a woodland ride, absorbing the late afternoon warmth of one of those dreamily mild early spring days.

It made me stop to look more closely at my surroundings, to listen more intently to the sounds that threaded the still bare, but bud-swelling branches. I saw a bee-fly nosing about the brown leaves piled at the base of a tree and heard the hungry pecking – so very much quiter than the drumming I’d heard earlier – of a great spotted woodpecker endeavouring to get at whatever lurked within a split in the bark of a nearby silver birch. I looked back up the path along which I had just walked to see it scattered with the winged motes of tiny insects glancing the sunshine.

I haven’t posted on this blog for a few weeks and wondered what I might write when I came back to it, wanting on this occasion, perhaps, to give a more original take on the welcome unfolding of spring. The things is, days like today just cannot be ignored and the substance of them not requiring of any supposedly artistic contrivances in recounting them.

It was a snatched half hour on the way home from work, in a fine old wood on a splendid spring day. Simple as that.

Bumblebees abroad

So not a fortnight after shivering in the sub-zero, snowy cold, spring raises its head above the wintry parapet for a first, tentative look around, giving all a much appreciated impression of what’s to come once winter has finally done its bit. Such caprices of prevailing conditions is, I think, one reason why the British are so renowned for spending much time discussing the weather. As I type a rather cold day is plummeting again towards zero and while that latter season is not done yet, its relenting does at least allow for a brief reacquainting with some welcome, familiar faces. The newts have returned to my garden pond and I was delighted to catch sight of a comma butterfly racing beneath the fresh spring sunshine. And we have, of course, the reappearance of the bumblebees.

Bumblebees are well-suited to the mood-swings encompassed by the British climate at this time of year, as also will be found other regions where an early flight-season might present them with some decidedly inclement periods of weather to deal with. There is actually a species, one Bombus polaris – the Arctic Bumblebee, that lives quite happily in the high-Arctic latitudes of Europe and North America. Being covered in furry layer of long hairs certainly helps in this regard, but they are able to employ other tricks. Not least of these is the ability, having disconnected the wings beforehand, to use their flight muscles to ‘shiver’ and raise their internal body temperature high enough for them to fly and forage. So even when basking alone is insufficient to achieve the required minimum internal flight temperature of 30°C, they are able to help things along enough for them to be active in air temperatures as low as around 10°C (I have on occasion observed bumblebees out and about in 8°C).

It is the buff-tailed bumblebee (Bombus terrestris) and the aptly named early bumblebee (Bombus pratorum) that are most likely to provide sightings of the ‘first bumblebee of the year’. Bumblebee colonies do not persist through the winter as with honey bees and only the queens hibernate. Having mated the previous summer, she will emerge from her torpor, firstly with task of finding food to replenish her reserves and bring her reproductive system back into function, then with the similarly pressing need to find a place to found her nest. The buff-tails this will be underground, often making use of old rodent burrows. The early bumblebee is less picky in terms elevation, as content to nest off the ground as it is under it.

Suburban invasion

A fall of fieldare

A covering of snow and persistent sub-zero temperatures across our part of the country appears to have prompted something of a suburban invasion. This winter seems to be a good one for winter thrushes around these parts. Every area of woodland or scrubland has had its attendant flock of redwing, scouring the branches for berries (the berry crop, for example, on hawthorn last autumn was the best I can remember for years). There have been fieldfare too, but in collectively smaller numbers, as would befit the relative abundant of the two species wintering in the UK each year. Both species descend southwards from the likes of Scandinavia and Russia to escape the harsh northern winter and feast on our autumn fruits, shifting to a more invertebrate-based diet later on when the berries become fewer and further between. The song thrush-sized redwing can number upwards of 8 million, dwarfing (to say the very least) the UK’s Scottish breeding population of a dozen or so pairs. The handsome chestnut and grey fieldfare occur in rather smaller quantities, but with well over 600,000 birds coming to us (usually only 1 or 2 pairs breed in Scotland) they are a common enough sight.

It may just be coincidence, with the exhausting of the berry crop around the countryside, but it seems that the recent snowfall has encouraged them into the gardens in search of sustenance, places where some berry-laden holly bushes and such like might still be heavy with fruit. The soft chack-chack-ing of the fieldfare and thin, whistled contact call of the redwing has become a familiar sound around town over the recent week or so. In our garden, for instance (not far from Southend in Essex), we normally have a handful of redwing turn up a few times each winter, with the fieldfare being a far less frequent visitor. The 36 strong flock of the latter, with a couple of redwing thrown in for good measure, crowding into the crown of our cherry tree, was therefore a most welcome surprise.

Such icy shifts in the weather ask questions of our winter wildlife, as alluded to in the previous post (and a few winters back my parents had a woodcock spend the day in their back garden, something to which the supermarket shoppers over the back fence would have been quite unaware!). Next week the forecast is suggesting a change perhaps to the low-teens centigrade. Within a few days we might be seeing the first butterflies of the year!

The tenacity of small things

A snowbound Pound Wood nature reserve

Snow comes to the South-east of England, with the promise of sub-zero temperatures for the days ahead and I find myself freshly fascinated by one small bird. This small birds is, in fact our (and Europe’s) most diminutive; the goldcrest is on average a shade more slight that the closely kin, firecrest.

The fascination in this instance stems from the bird’s eating habits. With probably more than a million goldcrest resident in the UK, plus many more that come here to winter, it enjoys a fairly numerous presence in this country. And while a realise that the British winter, especially down south, is a good deal milder than elsewhere in Europe, I still find it rather impressive of such a tiny bird, that it is resolutely insectivorous. A couple of our summer migrant warblers, namely the chiffchaff and blackcap who share a similar dietary predilection to the goldcrest, remain in the south of the UK for the winter, but both these birds will turn to fruit to tide them over through the tough times. Yet the goldcrest sticks to its guns.

Herein lies the tenacity of small things.

Wild Geese

Winter is a time for flocks, of the birds in their millions that move southwards in search of conditions less harsh, be they Scandinavian thrushes, sandpipers or plovers, ducks or geese. It is to the last of these that my attentions are drawn to here.

The sight of wild geese, for me, carries with it something quite unique. They could be the pink-footed goose by the thousand, in a murmuring clamour overhead and drifting down skein after skein onto an East Anglian marsh. Or perhaps the gathered, soft and ceaselessly babbling brent geese crowding onto a coastal grazing marsh, edged off the shore by a rising tide. The brents come in their thousands close to where I live and their gatherings something I relish with fresh anticipation each year. The huge flocks of pink-feet that grace the Norfolk marshes (as well as elsewhere) I get to enjoy less frequently, but never a fail to provide a highlight on any winter visit to that county. Both come to us from well within the Arctic, bringing with them a breath of the wilderness to wherever they amass.

There is another I want to mention here, a bird not without some controversy. I was out just recently on the RSPB’s West Canvey Marshes. Across the fields were not the thousands aforementioned, but still geese in their hundreds. They were not pink-feet or brents, but Canada geese, non-natives introduced from North America initially some three centuries ago and widely scorned by birdwatchers and ornithologists as a result of their unintended misdemeanour. Opinions will always be divided and the debate is perhaps a healthy one; alien species can bring (and have brought) problems for native wildlife. With the Canada goose, its presence in our country has been a long one and it’s not likely to be going anywhere too soon – there are getting on for 200,000 spread across most of the UK. The 300 or so scattered across this Essex grazing marsh – some ambling purposefully among the tussocks and grazing the shorter turf, some just loafing or snoozing – were no less a ‘completer of pictures’ for their lack of true British lineage. The scene, I think, would have been poorer without them.

Jackdaw

Jackdaw (Corvus monedula)

I have long been a fan of the crows, such canny and resourceful birds as the are. The jackdaw is no exception. I have enjoyed many a close encounter with this small and rather smartly adorned member of the clan, often involving visitors to the garden with a keener than usual interest in our alfresco dining habitats or nothing more than a generally inquisitive and somewhat mischievous curiosity in whatever we happen to be up to.

Much has been said about their intellectual qualities, as indeed there has about many species of crow. Konrad Lorenz, for example, sought an insight into the communication among his own free-flying flock of these most loquacious of birds, translating many of the numerous kiarrs and kraws that comprise their rich and varied ‘vocabulary’. It is often the case that a bird with a particularly developed syrinx (the organ that makes it possible for birds to produce their songs and calls) are those that can deliver the most complex and intricate songs. Crows however, buck that trend, having as they do this highly developed organ, but very little in terms of melodious song. It is something perhaps with crows that is put more towards the great array of communicative sounds that many of them possess, such as can easily be observed such birds as jackdaw, rook or raven.

It is my own increasingly crepuscular habits of late that bring the jackdaw to the pages of this blog. I have been enjoying many a dusk visit to my favoured haunts, such as is necessitated by the shortened winter days and correspondingly limited opportunities around work. It is this that has led me to the discovery of a jackdaw flock that comes together to settle among an expanse of dense scrub. With the light fading a couple of hundred birds gather for their wonderful preliminary winter roosting ritual. As one, the flock swoops and banks over the treetops, tricking the watcher into thinking that they’re about to descend before sweeping upwards into the sky. A turn this way and they almost disappear with the thin line of the wings angling straight ahead nearly lost in the grainy light; a turn that way and the full silhouette of the wings looking blacker than ever; all the time chattering and chuckling to each other as they perform their murmuration. It is not quite the 30-40,000 birds that can quite literally fill the air over the Norfolk Broads (click here for a short video that can only realistically provide an small inkling of such an extraordinay spectacle), but it is nevertheless a small thing of beauty and wonder.
