Snow on the marsh.

25th January 2013: It doesn’t snow often in the UK Midlands; when it does fall it rarely lasts for more than a week or two. Snow arrived a week ago: early Friday morning. Virgin snow carpeting the marsh offers an excellent opportunity for me to see which animals are active over a known time, and how far and where they have roamed. The snow in Hoo Brook Wood (not Hoo Wood) was peppered with animal tracks. Badgers, foxes, muntjacs, mice, mink, rats, pheasants, ferrets, many kinds of birds, they all seemed to have had a wail of a time.

Mink tracks.

Nothing much had moved through Wilden Meadow over the past 24 – 30 hours, apart from rabbits, pheasants, and the north marsh foxes. There has been plenty of activity around North Pond, though. I followed a set of fox tracks to a thick bramble patch on a knoll I know to be their summer den. Three cormorants sat on the power lines, west of North Pond, above the river. A couple of buzzards flew down from Hoo wood. Green woodpeckers squawked frantically as they sped from one tree to the next. Magpies shrieked at me, as did jays. Many other smaller birds chirping and flitted about, adding a little extra ‘feel good’ factor to a freezing cold day. A single rabbit had fought its way through the snow, in the direction of the beach. Marsh cows bellowed from the north pasture; one of them, in particular, has a really freaky bellow that sounds like some kind of strange exotic bird call.

Various water birds called from the flooded withy wood. I call it a withy wood, but there are many different kinds of trees growing in there, including willow, alder and silver birch. I saw vague, dark, bird-like shapes moving about on the water, but not clearly enough to identify. A coot called from somewhere nearby, and there was at least one moorhen in there too. I crept slowly, one step at the time, through a tangle of bracken, brittle willow-herb and various other general scrub. Eventually, I reached the line of closely growing, spindly, trees surrounding the hidden pool. I know this pool well, having explored it many times during the summer, but the water is too deep at the moment to venture too far into it. Trying not to alarm the birds, I used binoculars to peer through the tightly packed tree trunks. I saw stands of tall bulrushes growing in black water, but no water birds. I recognised a few duck calls; there were others, though, that I couldn’t identify. The short, sharp, double and triple whistle, that has attracted my attention for a quite a while, Dominique thinks is a Redshank. Dom has a far better grip on bird calls and identification than I do; she regularly surveys this area for the Trust. I stood and waited amongst the trees, in freezing water, for perhaps fifteen minutes without seeing a single bird. Boredom got the better of me, and I gave up. I trudged back crunching through ice-covered water to the track, and continued towards the beach.

The beach was strangely without signs of animal activity. The rabbit track I had seen earlier had turned from the path and moved off towards to north pasture. Usually, the beach is a rabbit hot spot. Looking back, it was my own winding, ragged foot prints that spoiled the pristine snow.

The first human footprints I saw, apart from my own, were those, I assumed, of the grazier visiting the cows in the north pasture. Judging by the marks in the snow, he/she used a sled to transport whatever was needed by the cows that morning.

Otter tracks at the north end of the corridor.

Further along the corridor to the tenant farmer’s field, an otter track followed the river bank. The trough the otter makes in the snow stretched into the distance, towards the field gate. As always, fox paw prints dogged the otter prints. The fox will follow any track in its territory, even mine. The otter had left the river ten metres north of the field gate, and continued walking north along the corridor to return to the river at a point where the corridor turned sharply away from the river bank –  a distance of around 150 metres. Dominique and I saw a similar otter track in the snow, in exactly the same place, early last year.

I climbed the north gate to the tenant farmer’s field. The north marsh fox had squeezed under the gate before me. It had trotted along the same riverside path that I follow. Now and again the fox left the path to search around the base of a tree trunk, or to investigate the track of a small animal on its way to the river bank. At one point it had walked out along a snow-covered branch overhanging the river, leaving its paw prints as evidence. At the south gate of the tenant farmer’s field, the fox turned left, and headed towards the middle wood. The south gate leads to the south marsh.

On the other side of the gate were the tracks of the south marsh fox. It had walked up to the gate, turned towards the river, mooched about on the silt bank for a while, and then walked back the way it came. Just like the north marsh fox, the south marsh fox used the riverside path.

Otter tracks at the north end of the south marsh.

Halfway along the south marsh it dawned on me that I couldn’t hear any bird song. There wasn’t any animal tracks in the snow either. It was a bit spooky down there, and a little like a snow desert I thought. I paid particular attention now, and searched for animal signs along the riverbank, around brash piles, and close to trees, but I didn’t find any! At last, I saw a track crossing the path between the drained south pool to the river. It was an otter track. The otter had climbed out of the river, up the bank, across the path and had walked 25 metres out into the empty pool, did a loop and returned to the river. As with the otter track in the corridor, fox paw prints ran to the side and in between the otter’s.

Otter and fox tracks on the drained south pool.

The otter and fox tracks were the only sign of animal activity I could find on the south marsh. I found a fox lie-up in an old brash pile, and the likely site of the south fox’s den at the far end of the marsh. I realise that I was only looking at a maximum 30-hour time slot, but I did expect to see more signs of life on the south marsh. Maybe all the animals had moved to the north marsh when the trees were being felled, and have not bothered to return. Perhaps the south marsh fox has eaten all the animals. I don’t know! Compared with the north marsh, though, the south marsh does seem desolate. Perhaps the animals will move back in spring. Further investigation is necessary. . . .

  1. You are correct, Alex! Food is difficult to get when snow is on the ground. The effort expended when foraging in freezing temperatures quickly saps energy, and as we know, it is more efficient to stay warm and cosy at home. . . .

  2. What an interesting post Mike! I’m so glad you’ve documented the goings-on in the snow since I haven’t been able to get down to the Marsh for a while – surveyed yesterday but there wasn’t much around. I’m pretty sure I’ve heard greenshank in the withy wood now and had a few skylark passing over on Sunday which was a new one for the survey. Interesting that the otter prints are in the same place as last year – I wonder if this suggests regular usage of that stretch of river. I can’t wait for the spring and fox cubs, flowers and butterflies!

    • Thanks, Dom.

      I think the withy wood is quite a jewel, as you know.

      Otters are living on the marsh, Dom. I don’t think they visit to play in the snow. 😀 I am pretty sure there is a holt on the island. There are often otter tracks in the mud on the west side of the Stour, opposite the corridor, and I’ve seen an otter playing in the slack water at the south end of the corridor. Also, the otter/otters are regularly using the track along the corridor – it’s quite a deep worn track now. The north foxes are heavy user of the corridor, but they walk all over it; zig zagging, following scents, checking this and that. The otter tends to move in more of a linear way, and deepens a track that it uses regularly. As I am writing this, I can hear a muntjac deer barking on the marsh; it’s quite distracting!

      At the north end of the corridor is a double posted wooden electricity pylon. There are two tracks around it; an otter regularly uses the riverbank track, and I think it might be used most nights.

      I passed the withy wood this evening, and again heard the pheet – pheet – – pheeeet whistle.
