It seemed like a good idea at the time

I began 2012 with a post about the birds in our garden at Tense Towers. On a similar local theme, I am going to end the year, and kick off the next, with another Tense-centric ornithological project.

A couple of birders have set up a national* challenge called Foot It for the month of January 2013. In essence, anyone taking part estimates the number of species that they are likely to see on their local patch, during the month.

The catch is that no transport is allowed, other than your feet. You have to walk there AND back. So, with the prospect of some healthy exercise and a bit of nature watching to boot, what's not to like?!

I've limited myself to a 2.5 mile radius of Tense Towers, because I'm lazy and unfit in the faint hope that I can manage a 5 to 6 mile circular walk if there's a particularly tricky species to see (there is, a Little Owl often roosts on the perimeter of my notional circle!).

Fortunately, there's plenty of habitat not too far from home, a good mixture of rivers, fields, lakes and woodland. However, before I've even taken the first step, I may have tripped myself up by estimating an optimistic 89 species.

As my occasional (oh, ok, constant) mutterings have alluded to of late, there's been plenty of rainfall around the country. I carefully forgot this fact when calculating my species target, so if the Great Ouse is in flood, I will not be able to reach Little Linford Wood without a detour of several miles. This would involve a journey to the east or west to find a bridge that is passable and not underwater. A brief glimpse at the local OS map (Landranger 152) tells me that this would mean a 15 or 16 mile hike. Not impossible, obviously, but rather more of a challenge than I was initially contemplating. The days when I could manage 90km in 19 hours are long gone and have been filed under "Memories of things I've done, but without the pain".

Here's hoping for some dry weather to start 2013!

* Actually, it's gone international, with entrants from The Netherlands and Austria.

Norfolk and tea rooms

Our Lass was keen to visit the coast during the Christmas break, as she starts to pine if she doesn't have a fix of shoreline every so often. Boxing Day looked like it would have the best weather and so it proved. We left Tense Towers early and were most of the way to Norfolk before the sun put in an appearance above the horizon.

Having breakfasted near Ely, we pushed on to our first port of call, RSPB Titchwell, where we were pleasantly surprised to discover that the car park wasn't yet full. This may have been due to the Visitors' Centre and cafe being shut (but, fortunately, we'd checked beforehand and made other arrangements).

With a cold breeze for company, we walked along the causeway to the beach, stopping occasionally to scan the lagoons with our binoculars. There were plenty of Golden Plover about, huddled on one of the low islands.

Whilst several small flocks of Brent Geese were moving between the lagoons and the marshes. 

The light from the low sun threw up some odd reflections on the windows of one of the new hides. At first I thought they'd run out of cash and used clingfilm instead of glass.

Once through the dune bank, we stopped for a while to watch some Turnstones searching for food amongst the razor shells deposited on the high tide mark. In the photo below, the bird furthest from the camera has a slightly deformed bill, the top mandible being longer than the bottom one.

The tide was out, so we wandered across the beach towards the water's edge. This is usually the only walking scenario where Our Lass scoots off ahead and consequently I have a large collection of images like this one...

There were plenty of species to be seen: Oystercatcher, Bar-tailed Godwit, Curlew, Sanderling, Grey Plover and Redshank.

Once we'd had enough of being buffeted by the breeze, we retraced our steps and went to explore the Fen Trail, which was much more sheltered, and we managed to spot four Marsh Harriers.

The bird feeders behind the Visitors' Centre were busy with finches, including several Siskins and a solitary Brambling.

By this time, grey clouds had replaced the sun, so we drove a few miles south to RSPB Snettisham before we lost the light completely. From the sea wall, we scanned the huge mudflats of The Wash and could see distant flocks of waders. The tide had turned, forcing these flocks back towards us, but unfortunately we knew that dusk would fall before high tide. Worse than that, it started to rain, further reducing visibility, so we didn't manage any close-up views of the wheeling and whirling flocks.

I did manage a few shots of the far throng whilst there was still some light...

but I think we will have to return in the not-too-distant future when tide, time and weather allows.

On the journey home, despite it now being dark, we detoured slightly to call in at WWT Welney. Not so much to see the wildfowl, but more because the cafe was open late.

"Pot of tea for 4, please, but only two cups."

Christmas in Little Linford Wood

Merry Christmas, dear reader!

Season's Greetings from all at Tense Towers.

Here's hoping the preparations haven't left you prickly and crackers.
Especially as it's threatening to rain, dear...
which could leave you pining like a dog...
and wondering how long it will be until the next dragonfly sighting.

Here's wishing you all the best for 2013, wherever you are, whatever the weather and whichever branch of natural history fires your passion!

Probability theory and caffeine

In mathematics, the Law or Rule of Nine states that any positive integer is divisible by nine only if the the sum of its digits is also divisible by nine. For example, 72 (7 + 2 = 9) or 108 (1 + 0 + 8 = 9) or 396 (3 + 9 + 6 = 18).

In Tenseworld, at least this past week, the Rule of Nine states that during any visit to a coffee house where food is ordered, the number placed on your tray (to indicate to the barista where to serve your order) will be nine.

This happened three separate times (between two different coffee houses and on three separate days). What are the chances of that?

And none of them were for cake or biscuits. Those odds just keep lengthening!

Stop press: Just checked my post list and that was blogpost 333. Gulp!

December in Little Linford Wood

There was a very real possibility that I would have to resort to using the opening paragraph from November's blogpost to begin this month's visit. Once again there had been a great deal of rain, with the ground now so water-logged that it didn't take long before rivers and streams overflowed.

However, for several days, the weather forecast had been predicting a 24 hour dry spell on Friday 21st December, so this seemed like my chance. Sure enough, not long after dawn on the allotted day, the sun broke through the clouds and the greyness gave way to blue skies. Fantastic! OK, so the paths would be muddy enough to please a hippo, but we can cope with a bit of mud. What's the worst that can happen? It's not like it's the end of the world...

A few minutes later, I had cause to remember that quip as I discovered that the road across the river valley was closed due to flooding. Again. So a bit of a detour was called for, through Newport Pagnell, where the extent of the flooding was visible from the road bridge. I had decided to park in a different place for my final monthly report, so that I could photograph the approach to the wood from across the fields to the south. This meant the walk would be a little longer and muddier, but the low Winter sun would light up the scene perfectly.


Eh? Where had all the fog come from? I phoned Second Born to check whether it was still blazing sunshine at Tense Towers (less than 2 miles away) and it was. I don't think she believed my very local weather report! 

Even as I ended the call, the view back towards home started to take on the feel of a post-apocalyptic nightmare. Surely not... Well, there wasn't any time to worry about that, as those blogposts don't write themselves.

So here we are, back on more familiar ground. And the good news was that there was plenty of water in the car park pond! In fact, I don't recall ever seeing it this full.

With all the dampness about, mosses and fungi were thriving on any surface they could find.

Towards the centre of the wood, where four rides formed a junction, there used to be an old Oak tree. This fell down many years ago and had been slowly decaying with the help of an army of invertebrates. To replace it, come local school children planted a sapling in 1991 and this is now into its third decade. Still some way to go to assume the mantle of its forebear, mind

Just so that we didn't forget the wheel of the year is turning, Hazel catkins were already in evidence and connected to the wood wide web.

Long before the Wildlife Trust was involved with the wood, there must have been some small scale charcoal production on the site, of which these rusting oil drums are the only evidence.

At the north end of the wood, the meadow had emerged from the flood and the sun had finally put in an appearance, which prompted me to head back southwards. There were only a few species of birds to be seen or heard, but Jay, Marsh Tit, Little Owl, Sparrowhawk and Little Egret were a pleasing collection, nonetheless.

Back inside the wood, I was fortunate to meet the reserve warden. For me, it seemed a fitting end to the year, and this blog project, to thank him and his team for all their hard work in maintaining the habitat of Little Linford Wood. It is a special and biodiverse place, long may it remain so.

Yep, it was muddy.

In a mere hundred years' time...

First Born emailed me the other day, asking why this Friday was going to be 'Wear your Rush t-shirt to work day'? As I was up to my oxters in a particularly knotty problem, I didn't reply immediately, and then promptly forgot about it. Oops.

A few days later, I was sat in a restaurant with Second Born (Our Lass being AWOL on yet another festive social occasion), and I remembered FB's question. SB just gave me a look (the one reserved for the merely unworthy rather than the full-on Queen of Scathe eye roll) and said "It's the 21st of December... as in 21/12... or even... 2112."


How. Stupid. Am. I?

Cue sheepish text message to First Born.

For the uninitiated or just plain young, Rush are a Canadian rock band from w-a-a-y back, who are still going strong and selling out venues around the world. One of their most celebrated albums is 2112 from 1973, which inadvertantly launched the Starman logo, featuring a naked man and a five-pointed star. This isn't the time and the place for an in-depth discussion of the various pagan or Vetruvian Man connotations of this symbolism.

However... oddly enough, yesterday, during our monthly gathering at the local nature reserve, all manner of rustic and festive decorations were being hand-crafted to be sold as Christmas decorations. There were bunches of Holly, bouquets of sumptuous evergreen cuttings, Christmas wreaths and Stars of David woven from Willow and Dogwood. Not to be outdone, with half an eye on the more pagan roots of the Midwinter solstice (and with the thoughts of 2112 still fresh in my mind), I managed to fashion this festive decoration for Tense Towers.

Have a Happy Winter Solstice, er... Saturnalia... no, Dies Natalis Solis Invicti... I mean, Yule... look, please add your festival of choice and/or delete as applicable.

Catchy felicitation, eh?

The strange case of the [insert name of animal here] in the night time

Recently, a calm and reasonably dry evening (this is a weather report, not a continence statement) saw me deploying a wildlife cam at our local nature reserve.

I am not sure that I've yet discovered the secret of successful camera trapping. I seem to pick the wrong location for subjects, or a location with vegetation that triggers the camera continuously, or even the wrong weather.

Exhibit A, a whole load of nothing
But faint heart never won a fair maiden, as they say (though what they actually said was a whole lot ruder, as I recall, but you get the idea). So another attempt was ventured.

The camera was targeted on a chicane in the path, with a view of the bit between the two bends. In truth, the path at this point is also a causeway between two water bodies, a fact that will increase in prominence as this blogpost unfolds.

Having ensured that:

1. a memory card was installed;
2. said memory card was empty and formatted;
3. the batteries were fully charged;
4. the lens was clean;
5. the camera was secured firmly;
6. the camera was pointing in the correct direction;
7. there wasn't any vegetation likely to trigger the PIR unnecessarily;
8. I had uttered a silent prayer to whichever deity was on wildlife duty that day;
9. the camera was still pointing in the correct direction;
10. it was still night time and I hadn't wasted the whole evening messing about with points 1-9.

... I returned home.

Sixteen hours later, I was back on site for the retrieval mission. Well, one always hopes it will be a retrieval mission, rather than a forlorn searching in the undergrowth and a general rant about how you can't leave anything lying around these days that's not tied down. And it was tied down, so what did they think they were doing, the complete and utter b*st*rds etc.

Fortunately, the camera was still there, though a quick check of the image count showed a paltry 24 photos. As at least half of these would've been triggered by me when setting up beforehand and switching off the camera afterwards, it didn't seem like it had been a particularly fruitful night.

However, once the memory card was plugged into my pc, it became obvious that some wildlife had triggered the camera. And whilst the images weren't great (I'd set the sensitivity to Normal, when perhaps High would've been better), they did prove the presence of several species.

Shortly before 10pm, a Fox put in its first appearance.

Much later at nearly 3am, there appeared to be a Badger foraging by the bench. 

But in between these times was the real surprise of the evening.

Either side of midnight, the camera was triggered by a creature that I was not expecting to be moving around during darkness...

A Mute Swan.

As mentioned earlier, the path is effectively a causeway at this point, so the swan was obviously shuffling from one water body to another. I suppose it could be in response to the fox's movements, though whether there's any danger for a swan if caught on land is debatable.

As one of my fellow bloggers remarked, "If you're up early, you're a lark. If you're up late, you're an owl. If you can't get to sleep, you're a swan!"

So all in all, it was an encouraging and educational experiment.

Note to self: remember camera

Rather than participate in the frenetic whirl of activity that is generated by the rapidly disappearing number of shopping days to Christmas, we went for some fresh air down at HESC, our local nature reserve.

And I remembered my camera.

There was still plenty of water about the place and some of the multitude of Mute Swans have now taken to spending their time in the smaller pools, rather than out on the main lake.

With a bit more judicious pruning, there will be a fantastic view from this bench...

though not everyone was excited about that as I was.

The view from the Near Hide along the side of the main lake was one of dull and dreary Winter dampness.

Until, that is, I noticed what was happening to the Teasel heads...

Teasel babies!

Back in the saddle

Ah, it felt good to be out in the fresh air again and mingling with the natural history. A crisp, bright morning, a little on the chilly side, but very welcome, nonetheless.

The priorities for the day were a walk and an eatery, so we chose Stowe Landscape Gardens as our destination, fifteen miles west of Tense Towers. However, our first port of call, en route,  was Foxcote Reservoir, where a pair of Long-tailed Ducks had been seen for the previous two days. These sea ducks over-winter around the northern and eastern coasts of Britain, so we were surprised to hear of a sighting just about as far inland as its possible to be in the UK.

The reservoir was as full as I have ever seen it, but bear in mind that I usually visit in the middle of the dragonfly season, so this wasn't a huge surprise. The first seasonal wildfowl we spotted upon opening the hide hatches was a male Goosander, his white plumage almost glowing in the morning sunlight. A few Goldeneye were present too, but we couldn't pick out the Long-tailed Ducks amongst the more usual Wigeon, Tufted Duck, Pochard, Teal, Mallard and Great Crested Grebes. Fortunately, help was at hand. Another visitor to the site had been diligently searching for them for several hours and had located the pair way, way, way across the other side of the reservoir, diving for food and hidden by a multitude of Wigeon. Our bins could just about make them out as two tiny shapes of a different pattern and colour to the surrounding duckage. Even deploying Very Wrong Len wasn't much of an improvement.

Long (way away) - tailed Ducks
After an hour of waiting hopefully for them to swim closer, we admitted defeat and resumed our journey to Stowe, with thoughts of a hot mug of tea very much in our minds.

Wonderfully Oddly, the car park was barely half full. I guess everyone else was Christmas shopping in the cathedrals of commerce. By sheer chance, we walked into the cafe with four minutes to go before lunch was served, no queue at all and a tasty menu to peruse. Winner!

Suitably fortified against the cold, we pottered into the gardens and around the lakes, discovering another seven Goosander in the process. For early afternoon, the shadows were already long, creeping inexorably across the ground and towards the night. 

View across Octagon Lake with Stowe School on left
As we completed the circumnavigation of Eleven Acre Lake, the sun lit up the Cascade and brought back happy memories of warmer times and dragonflies aplenty. Sigh.

Taking the path along the western edge of Hawkwell Field, we climbed gently towards the Queen's Temple, stopping briefly to have a bijou pedantic rant about the sign shown below. I know what they meant but...  Grrrr.

Er... which way?
After looping around onto Lord Cobham's Walk, we passed his Pillar and then the Gothic Temple, before descending to cross the Palladian Bridge.

Bridge in foreground, Gothic Temple on hilltop
This is where we spotted the Goosander, four males and three females, in fantastic late afternoon sunshine and quite near for such shy ducks. Yeah, I didn't have my camera. Before we could approach the side of the lake, a few children began throwing sticks onto a patch of ice floating on the water. The ducks swam off hurriedly, but bunched together for safety. At this turn of events, dark thoughts entered my head about how hacked off I would've been had I been carrying my camera, but then an amazing thing happened and I had to issue a heartfelt, if inaudible, apology. During the breeding season, we don't see such numbers of Goosander in this part of the world, so it was most pleasing to watch as the males became a little territorial over the females, with much vocalising and throwing back of their heads. The ladies were having none of it, mind, but it was interesting to see and hear their behaviour.

Reason enough to return to the cafe for a celebratory mug of tea and a slice of cake?

Oh, I rather think so.
