Birds of East Kent: Snow Bunting

Latest in an occasional series of posts discussing the different birds that can be found in East Kent and how easy (or not) it is to get a decent picture of them.

Palm Bay, Margate, March 2012

The Snow Bunting is a regular winter visitor to Kentish shores, albeit never in huge numbers. They can pop up just about anywhere along the East Kent coastline, but the most reliable place to find them is along the shingle beaches at Reculver, foraging amongst the pebbles.

I like to think of this smart little bird as the "photographer's friend" because not only is it very photogenic, it can also be very approachable. But of course, a flock of birds is only as brave as its least brave member, and so the closest you get to a larger group of Snow Buntings (known collectively as a "drift") may be when they fly over your head to the other end of the beach - half an hour's walk in the direction you just came from. However, if you're fortunate enough to find a Snow Bunting by itself (no easy task, since they usually blend in very well with the pebbles) and don't make any sudden movements, it may allow you to get within a few feet. The bird pictured below was so confiding I had to back away just to keep it in focus.

Kingsgate Bay, Broadstairs, April 2011

In summer, when they return to their breeding grounds in the high Arctic, the Snow Buntings undergo a dramatic change, with the males turning almost completely white. Here in Kent, they're invariably gone before we see them reach this phase, but if you're lucky enough to catch a straggler you might see the white plumage starting to come through. Compare the difference between the one above (photographed in early spring) with the one below (taken in late autumn).

Reculver, November 2009

So the next time you go for a walk along the coast on a bracing winter's day, keep your eyes open for these charming little birds. They may be closer than you think.

Sir Patrick Moore - A Belated Tribute

The final edition of The Sky at Night to feature Sir Patrick Moore aired last night on BBC 1 (and will be showing again as an extended episode on BBC 4 later in the week), so this seems like a timely moment to share a few thoughts I originally posted on the Sky at Night Flickr group a few weeks ago.


Many moons ago, my mum wrote to Sir Patrick, asking him for advice on what telescope to buy her astronomy-obsessed son, and he very kindly sent one of his famous hand-typed letters in reply, offering his usual brand of no-nonsense wisdom.

Years later, after going on to study astronomy at university, I was fortunate enough to attend one of Sir Patrick's BAA lectures at the University of Kent, in which he spoke about Mars for an hour (without notes). It was the period straight after lunch (a tough time to give a lecture), but he kept the whole audience captivated with his energy and boundless enthusiasm.

And just last month, I was watching The Sky at Night on BBC 4 when I was pleasantly surprised to see one of my photos featured in an item about the planet Mercury.

RIP Sir Patrick, and thanks for everything. You will be missed.

Birds of East Kent: Purple Sandpiper

The second in an occasional series of posts discussing the different birds that can be found in East Kent and how easy (or not) it is to get a decent picture of them.

Viking Bay, Broadstairs, November 2011

According to the RSPB website, Purple Sandpipers are supposed to be scarce south of Yorkshire, which perhaps explains why some local photographers have been known to risk life and limb (and their camera gear) clambering over wet rocks just to get a photo of one of these birds. However, despite what official sources say, Purple Sandpipers can in fact be found along the Thanet coastline every winter, with the stretch between Stone Bay and Dumpton Gap being a good area to get close-up shots of them. The photo above was taken from the relative comfort (and safety) of Broadstairs jetty.

Often described as "dumpy little waders" in the guidebooks, Purple Sandpipers are slightly smaller and not as bold as the more plentiful Turnstones with whom they share their winter haunts. Their propensity for skulking under the jetty, or creeping furtively along the seawall while picking at the seaweed-covered stone makes them easy to overlook unless you're actively seeking them out.

Distinctive features include a downcurved beak and mustard-coloured legs. The purple sheen that gives them their name is less obvious, but if the light hits them at the right angle, it shows up quite well:

Broadstairs, February 2010

Don't dismiss these "dumpy" birds; under the right conditions, they can be very photogenic.

Ocean of Storms

At first glance Oceanus Procellarum (the Ocean of Storms) appears to be one of the less interesting regions of the Moon, presenting to the casual observer nothing more than a vast, monotonous plain of dark grey lava, dotted with the occasional impact crater. But look closer and you'll find evidence of ancient volcanism on a huge scale, unlike anywhere else on the lunar surface.

Here's a 100% crop showing the Aristarchus plateau - an diamond-shaped block of uplifted terrain dominated by the dazzling crater Aristarchus and the 160 km-long Schröter's Valley:

Easily visible in a small telescope, the valley is the largest and perhaps most dramatic example of a lunar rille, a sinuous channel cut (a very long time ago) by fast-flowing lava.

Follow the terminator south and you come to the Marius Hills, a complex of some 300 volcanic domes and hills that - through a small telescope - look like pimples on the lunar surface:

Lunar Orbiter 2 photographed the complex from an oblique angle, giving an idea of the relative height of the domes, and a few decades later the Japanese SELENE/Kaguya mission discovered an intriguing dark pit in the area (shown here in a high-resolution image taken by the Lunar Reconnaissance Orbiter).

Incidentally, if you move your mouse over the cropped images you can compare the finished versions with one of the original photos, illustrating the dramatic improvement that image-stacking can make to lunar photography.

Reflex Action

I recall reading somewhere that photographers fall into one of three groups; those who delight in telling you what their camera/lens combination can do (but never get round to doing it themselves), those who delight in telling you what your camera/lens combination can't do, and the rest of us who just get on with it and take the photos.

If you've been following this blog you'll know that I take almost all of my wildlife photos using a small portable telescope mounted directly to a DSLR, thus getting the benefits of an apochromatic lens built to astronomical standards (while also having the option of popping in a diagonal and an eyepiece and using it as a conventional scope). Now I'm the first one to admit that this method has its disadvantages (namely: no autofocus, no aperture control, and no image-stabilisation), but that hasn't stopped some keyboard warriors from confidently reeling off lists of things that such telescopes are supposedly no good for, with "small birds in flight" ranking high on their chart of photographic no-nos.

So with that sage advice in mind, clearly I should give up all thoughts of trying to photograph Sand Martins popping in and out of their burrows like winged champagne corks...

I should also stop entertaining fanciful notions of catching a Swift screaming through the summer sky...

I really should abandon hope of trying to photograph a freewheeling House Martin gearing up for the autumn migration...

And I shouldn't even dream of trying to catch a low-flying Swallow hurtling across a windswept beach...

Birds of East Kent: Black Redstart

This is the first of an occasional series of posts discussing the different birds that can be found in East Kent and how easy (or not) it is to get a decent picture of them.

Black Redstart (male), Broadstairs, February 2010

The Black Redstart seems like a good place to start this series, as it was one of the birds that first tempted me into the realm of wildlife photography. Back in March 2005, after stumbling upon the Planet Thanet website (currently dormant, sadly), I saw a report of a Black Redstart - a bird I'd never knowingly seen before - along the coast not far from where I lived. The next day I wandered down with my binoculars, fully expecting it to have moved on, but it was still there and I got some terrific views of it flitting around. Inevitably, my mind turned to thoughts of what a great photo it would have made. This idea lingered in the back of my head through the summer until finally, a chance encounter with a cuckoo convinced me (to paraphrase Roy Scheider in Jaws) that I was gonna need a bigger lens.

Black Redstart (female), Kingsgate, March 2009

I've seen at least six Black Redstarts since that first encounter in 2005, but most of those sightings have been from a distance, with me standing at the base of a cliff while the bird flies to the top, or me watching from the top of the cliff as it disappears over the side. The few times I've been able to get one within range, it's either been half-hidden in shadow or between me and the sun.

All that changed however, when Barry Hunt's spectacular Eastern Black Redstart arrived in Margate for a week-long stay.

Eastern Black Redstart, Palm Bay, Margate, November 2011

I generally avoid "twitching" (I'd rather get a close-up photo of a common bird than a distant, blurry photo of a rare bird), but when a bird this handsome (and confiding) shows up in your neighbourhood, you've got to make the effort to go and see it. And, as all those who were there will remember, the EBR didn't disappoint, going about its business completely unperturbed by the array of big lenses pointing at it. Now if only I could find a "regular" Black Redstart that was as cooperative, I'd get the photo I've been after since 2005...

HC SVNT DRACONES

As beautiful as the Kent countryside and its surrounding coastline is, you know that wherever you go, you're never too far away from a road or a housing estate or an out-of-town shopping centre. It's still possible to get lost, but you can never get truly lost, and there are certainly no uncharted territories to speak of - the kind that medieval mapmakers used to populate with dragons and other mythical creatures. (Though if there were an uncharted region on the map of South East England, you can be sure that someone from the current government would try and put a runway on it.)

The thought of hundreds of shoppers dropping their bags and running in terror as a dragon wheels in the skies over the Westwood Cross is a strangely comforting one (well, to me at least), but in the absence of fire-breathing dragons, we have to make do with their insect counterparts. And judging by the number of dragonfly photos I've seen on Flickr recently, I think it's safe to say it's been a pretty good summer for dragonflies (and their damselfly cousins).

Over the last few months, at just one modest-sized pond in Canterbury, I've seen dragonflies of all different sizes and colours, including red ones:

...blue ones:

...yellow ones:

...and hawkers with colour schemes worthy of a Formula 1 car:

On reflection, perhaps it's just as well that the dragons' diminutive namesakes don't breath fire, as the above encounter might have burned the end of my telescope.
