Theodore Roosevelt, the 26th president of the United States, had a pet badger called Josiah.

Apparently, Josiah was given to the president as a cub in 1903 by a little girl in Kansas.  Roosevelt was on a tour of the country at the time, and when his train stopped and he stepped out of the carriage the girl literally thrust the baby badger into his hands, saying that it was called Josiah.

I can’t imagine this sort of thing happening to a president today, but Roosevelt was made of sterner stuff.  A rugged outdoorsman in his day, he took the event in his stride and adopted the badger.   He had many pets, including a guinea pig called Fighting Bob Evans, which gives you a clue to his character.

His family kept Josiah in the White House and fed him on milk, and as soon as he was old enough he would run around the building, biting the legs of passers-by.

Sadly, although Roosevelt went on to become the only president to be awarded the Congressional Medal of Honor, it seems that Josiah’s fate was less noble.  He was eventually sent to live in the Bronx Zoo on account of his habit of “hissing like a tea kettle” and biting guests on the ankle. 

Despite Josiah’s ignominious retirement, he did set the standard for badgers in the White House.  Barack Obama, take note – if you want to get ahead, get a badger…

Thanks to Louise for alerting me to this story.

Have a go at tracking a badger

This Sunday I found a lovely clear set of badger tracks from the field behind my house.  It seems this badger has a longer route than I thought, and it’s making me think about where its sett could be located.

If you want to have a go at tracking a badger, have a look at the photo below.  It may just seem like a patch of mud, but there’s a lot of detail in there.

See how many badger tracks you can find!

Today, one of my chickens laid the first egg of the new year.

What has this to do with badgers, you ask?  Absolutely nothing.  But this is my diary after all, and this is a date I want to keep track of, so here it is for posterity.

For the curious, chickens stop laying in winter and resume in spring.  The mechanism for this is controlled by daylight, rather than temperature, so if you want eggs all year round you need to put a light in the chicken shed.  I’m not too bothered about intensive egg production, so I just leave my girls to get on with it the natural way.

Since we got the chickens almost two years ago I have refused to buy eggs from a shop.  We’ve got used to proper free-range eggs fresh from the garden, and the shop-bought ones are terrible, insipid things by comparison.  Hence I’m recording the date so that I know when I can expect to resume my Sunday morning fried breakfasts next year.

Badger cub

Thinking about the badger sett has got me thinking about badger paths.

Badger paths are an absolutely classic sign of an active sett.  Badgers are well-known to be creatures of habit, and will follow the same route night after night and even generation after generation until the vegetation is worn away and quite deep paths are formed.   The urge to follow paths is obviously very strong.  There are many examples of fences being erected across badger paths and the badgers simply barging through.

But why is this so?  Why do badgers follow such regular paths?

To understand why, you have to stop thinking like a human and think like a badger for a while.

I’ve already mentioned the senses of the badger (see About Badgers).  Badgers have poor eyesight, but a very good sense of smell.  Unlike humans, who rely on visual information to navigate, the badger ‘sees’ the world as a landscape of scents and smells.  This makes perfect sense for an animal that is active in the hours of darkness.

Badger paths then, are not visual paths, but scent paths.  Each path carries the scent of the badgers that have used it.  When a badger is following a path, it is literally following the badgers that have gone before.  As a system it is simple and effective – the badger can find its way around a completely dark wood by using these trails, and in times of danger it can always follow them back to the sett.  It is difficult for humans to understand a landscape of smells, but to the badger, these paths must stand out like a bright shining road would to us.

But nothing with badgers is ever simple.   Many mammals have interdigital glands.  These are glands between the toes that leave scent when the animal walks.  Cats have them,  for instance.  When a cat scratches a tree it is not sharpening its claws.  It is leaving scent from its interdigital glands to mark its territory.

It seems likely that badgers also have interdigital glands.  This means that every time a badger uses a path it is not only leaving a signpost for itself and for other badgers, it is using the path to mark out the territory of the clan. Badgers use scent to identify members of their own clan, so a badger can easily tell which paths belong to them, and which belong to the neighboring clans.

So badger paths are not just the result of ingrained habits or an easy way for the badgers to get from one place to another.  Seen in conjuction with other territorial markers such as the latrine sites and scratching trees, paths are a sophisticated part of the social behaviour of badgers.

The weather today has been much warmer than of late.  It was a cold night, but the sun came out and the temperature went up to 8 degrees or so.  It doesn’t sound much, but compared to the last couple of weeks it feels almost tropical!

Rabbit tracks in frost

Rabbit tracks in frost

I went on my usual Sunday morning dawn stroll today.  When I set off it was still very frosty.

Here’s an example of tracks that you won’t find in a tracking book.

The pavement was very frosty, although the road had been gritted.  At some point in the night a pair of rabbits had crossed the road, hopped up onto the pavement and then gone through the railings to the field beyond.

They had picked up the salt from the road on their feet, and this salt had melted the frost where their feet had touched it, leaving this perfect set of tracks in the ice.

I decided to make the most of the day and went for a longer walk than usual.  I let my feet carry me in a big loop around the woods.  The Chinese Water Deer were out again, and the local buzzard seems to have found a friend, as there were two buzzards swooping and calling over the fields.  Either that or he was having a territorial dispute with the neighbour.

I thought it was time I checked in at the sett to see how the badgers were doing.  Of course, there was no chance of them being out at 9.30am, but I wanted to have a look round.  It gave me a good chance to look at the different parts of the sett.  In summer, when I’m actively watching the badgers, I don’t like to get to close to the sett for fear of disturbing them as scent can linger for a long while.  Today though, I thought I’d have a look, since the badgers would not be active until much later in the evening.

Everything seemed to be in order at the sett.  There were two entrances that looked to be in very active use.  Here’s a picture of one of them – note the relatively clean hole, without many fallen leaves or other debris.  You can also see how the sides have been polished by the coming and going of many badgers.  This is obviously well-used at the moment.

Very encouragingly, a couple of entrances showed signs of recent digging and of having been cleared out.  In the picture below you can see a furrow pointing directly to the hole, made by badgers dragging out spoil.  This is another classic sign of an active badger sett.

In the picture below, you can see that the badgers have dug out large amounts of dead leaves from this entrance.  This is a sign that they’re clearing out an old chamber for re-use.

Why is this encouraging?  Well, badgers re-dig parts of the sett at this time of year to make ready for the birth of cubs in February.  The sow prepares a separate ‘maternity suite’ where she can get away from the other badgers and won’t be disturbed.  The signs of activity at the sett all point to there being cubs on the way!

The interesting thing is that there is clear activity at both ends of the sett – the east and west sides.  This implies that badgers are in residence at both ends.  There is re-digging going on at both ends too.  Does this mean that there will be two separate litters of cubs from separate mothers?  Has there been a split in the badgers, so that different groups have taken to living in different parts of the sett?

All the books I’ve read suggest that all the badgers in a sett should be part of one single group, with only the dominant male and female breeding.  This wasn’t the case last year, as there were at least two litters of cubs, and the signs seem to indicate that there will be separate litters again this year.

I’ve also been thinking about the number of badgers in the sett at the moment.  If all the cubs survived (and I have no reason to think that they haven’t) then there will be at least 10 badgers in residence.  Do some of them leave home at some point, or do they stay in the group permanently?  Might this account for the active use of different parts of the sett?  If they leave, what is it that determines who leaves and who stays, and where do the badgers that leave go?  Do they join another sett, or start their own?

You see, this is the great thing about badgers.  We’re only in January and already they’ve got me confused.  I’m going to start the badger watching season as I finished the last one – with more questions than answers!

This is a mystery that needs solving.  Does anyone know where I can get a cheap copy of Hans Kruuk’s The Social Badger?  Even better, if anyone knows anything about the clan structure of badger groups and how they change over time, then please do leave a comment and enlighten me.

Frosty fields

Frosty fields

Well, we’re ten days into 2009, and so far the only way to describe the year is ‘cold’.

The temperatures have not been much above freezing for two weeks, with night-time temperatures as low as -10 degrees Celsius.

I spent the New Year on the North Wales coast.  Normally this part of the country is quite mild, as the sea acts as a huge storage heater and keeps the temperatures up.  This year, however, the sand on the beach was frozen solid, and even the rock pools had a thick layer of ice.   It was really cold.

Back in Bedfordshire, the weather has been even colder.  Since most of our house has no heating we’re regularly having to scrape the ice from the inside of the windows in the morning.  We go out each day with a kettle of hot water to defrost the water in the chicken’s drinker, as it freezes solid overnight.

I’m not complaining,
mind you.  It’s quite fun to dress up in warm clothes and get outside, and I’d much rather have this sort of cold, clear weather than the murky drizzle we get so often.

Tracking is almost impossible at the moment, as the ground is like stone.  I came across a fresh fox track on December 27th, just before the frost started.  It is still there today, and looking almost as fresh, fossilised in the hard, icy ground.

The best thing that happened this week was on Monday, when it snowed.  It was only a couple of inches or so, but it got me more excited than you can imagine.  This is the first snow since I started learning tracking, and I was itching for the opportunity to go out and look at the tracks.  I had visions of being able to follow perfect crisp tracks for mile after mile, and to see the full pattern of animal movements written across the snowy ground.

I was working for a long day on Monday, but on Tuesday I managed to get out for an hour or so in the early morning before work.  There were already thousands of tracks from the previous 24 hours.

Here’s an easy one to start with.  Here’s the tracks of our cat, Mayfield.  She was originally a farm cat, and she’s not at all put off by cold weather.  Here you can see the print of her back legs as she sat in the snow.

Our local fox has been quite active lately.  As long as he keeps away from my chickens then I’m happy to have him around.  Since the chickens have a de-luxe high security run (which they still escape from every now and then), there isn’t much danger to them.

Here’s the fox’s tracks.  Note that the fox, unlike the dog, has an almost perfect register.  This means that the rear feet go into the tracks left by the front feet, so the track looks like they have two feet rather than four.  You can see here that there is only slight overlap to show that there are two prints on top of each other.

The vast majority of tracks were from rabbits.  In fact, there were so many rabbit tracks that they obscured almost all the others.  Here is a classic rabbit track.

The direction of travel in this case is from left to right.  The two small prints close together on the left are the front paws, and the larger tracks on the right are the rear paws.  When hopping, the rear paws ‘overtake’ the front paws, leaving a track that seems backwards.

Some of these rabbit tracks are quite impressive.  Look at the tracks immediately above the stick.  There are two sets of rabbit tracks – one at either end of the stick – representing a single bound.  Ignore the trail going from bottom left to top left, and the one across the top of the picture.

Bounding rabbit tracks

The direction of travel is from right to left, with the rear paws quite far ahead of the front ones. This rabbit was obviously bounding along at a fast pace.  The stride length was 120cm, which is a big distance for a rabbit to travel in mid-air.  Actually, the guidebooks give a stride length of 80cm for a rabbit, so this one must have been really sprinting.  It may even have been a hare, as hares have strides of up to 250cm, but the tracks themselves looked like the other rabbit tracks, so perhaps I’ve got a record-breaking rabbit on my hands.

Frustratingly, there were no badger tracks in the area.  I was longing for the chance to trail a badger through the snow, and to try and build up a picture of it’s nightly movements, but it was not to be.  Perhaps badgers don’t like snow.  The hard frost would mean that even a badger would find it difficult to dig up food.

I decided to have one last try at finding badger tracks before the snow melted, and after work I set off for the wood where the main badger sett is.  I had an idea that I might be able to find tracks in the pasture field, as I know they forage there and I’ve seen them in that area before.

I walked up to the wood at about 10.00pm (I worked late!).  The half-moon and the snow on the ground made it quite possible to wander around without a torch.  Unfortunately, by the time I arrived, the pasture field had been trodden over by the resident sheep, countless rabbits, and a solitary human.  Finding individual tracks was almost impossible.

On the borders of the wood though, I came across a trail that looked right for a badger, and I was able to follow it into the wood itself.  There, on the undisturbed snow, were two lines of badger tracks – one going away from the wood and one going back into it.

And there they were – a little distorted, but unmistakeably badger tracks.  It seems that only a single badger had been out foraging – the others probably had more sense and stayed warm underground.

I didn’t get the chance to follow badger trails as they wandered across a pristine field of snow, but it was fun to go out and look for them.  I hope that we get more snow this winter – ideally at the weekend – so I can go out and spend hours literally following in the footsteps of the wildlife.  In the meantime, may the Protector of All Small Beasts look after the animals and birds and see them safely through the cold spell.
