Update
In terms
of simply watching badgers, the 2004 viewing season was of a
high quality. However, in terms of trying to understand badger
behaviour, it was also very frustrating. I'm quite convinced,
for example, that the current perception of badger society is
very misleading. I do not believe that a Clan is led by a dominant
male and female pair, or that the dominant female will kill
any other cubs born in the main sett. Unfortunately, I have
neither the knowledge, nor resources, to devise a research programme
to find out exactly how badger society works down here in Devon.
If any research centre would like to join forces with us, bringing
their knowledge to our watching facilities, we would be very
happy to hear from them.
Clan
Membership.
It
will be late February before Anne and I start watching the badgers
again. We will be looking to see if Alfred is still there, how
many females have bred and how many adults are in the clan.
We do know that so far, we are once again having a very mild
winter. If this continues, I would expect the clan to have kept
the two "extra" adults. We will not know how many cubs are present
this year until early May, when they usually come above ground
for the first time.
Video
Diary Update
Unfortunately,
the reorganisation of the BBC has had a major impact on the
Natural History Unit, and it is unlikely that they will be doing
any more Diary Update's. We are hoping to put a short video
clip of badger action on this web site. However, it will not
be live or updated, as this has proved to be prohibitively expensive.
Photography
Evenings
These
are proving to be very popular, with pre bookings for this year
already in excess of the total that came in 2004. Those who
came in the summer were very pleasantly surprised to find that
they were taking their pictures in daylight. We realised that
our literature gives the impression that all pictures will be
taken in the dark. In fact, the evenings usually take place
between 7.00pm and 9,00pm, so whether or not you will need a
flashlight depends upon the time of year you come.
Opening
Times
With Easter arriving early this year, we will be opening on
the 25th March for both viewings and photography evenings. We
will be warning guests to keep an eye on the weather and wrap
up warm, as it can be cold at that time of year.
We hope
you are able to come and watch the badgers with us this year.
Kevin and
Anne.

Clan
Membership
The
watching season is well under way, and we now know that we have
11 principal members of the Clan and one occasional visitor.
Alfred is
still the dominant male and looks in good condition, apart from
a small bald patch just above his tail. This is more likely
to be the result of Mange and fighting, rather than old age.
For the
last few years the Clan has had a constant adult membership
of seven, three males and four females. Whatever cubs were born
in any particular year have always been forced out in the normal
dispersal process, when winter food shortages started to occur.
They faced a perilous journey to find new homes, either with
a nearby Clan that has a suitable vacancy or until they can
find a territory of their own. This year, however, two of last
year's six cubs have stayed with the Clan, taking the adult
membership up to nine. The reason for this is almost certainly
the weather.
Weather
conditions
The
winter of 2002/3 was unusually mild, but the winter just gone
was even milder. We only had snow on two or three occasions,
and it stayed only for a very short time, much to the disgust
of our young daughter. Frosts were also rare and short lived.
The consequence of this was that the ground rarely froze and
so earthworms, the badger's staple food, would still have been
available. It is likely that the larger food supply than usual
meant that the adults only had to force four of the cubs to
leave. It will be interesting to see if, when we have a normal
winter, the Clan shrinks back to seven. As it is very difficult
to tell males and females apart when they are young, we do not
know the sex of the two new adults. If they stay to the point
where the differences do become more apparent, it will be interesting
to check one of the dispersal theories. This is that when the
adults kick the cubs out, they start with the males. According
to this, both of our new adults should be females. We will let
you know as soon as we do.
This
year's cubs
This
year just one of the four females has bred, and she has had
two cubs. Even if last years cubs are females, they were too
young to breed this year. On the face of it, this disproves
another theory about badgers, namely that an individual will
only breed in alternate years because rearing cubs takes so
much out of them that they are not in good enough condition
to breed the following year. However, we know that this year's
mother also had cubs last year and the year before! The Clan
seems to have one non- breeding female. She is the largest of
the females, probably because she does not suffer the drain
of rearing cubs. This year's mother is the smallest, but still
manages to breed most years. This just goes to show how little
is actually known about badgers. There are still many areas
for further research.
Viewing
patterns
We
have just come out of a six-week dry spell which produced unusual
viewings, and which showed that a large part of a badger's behaviour
is determined by weather and its impact on their food supply.
Our normal viewing pattern is four to six badgers out at once
with lots of interchanging. We would expect to see perhaps nine
of the clan during a watch. The dry spell drove the earthworms
deep underground, and as a consequence, the badgers were hungry.
Within a few minutes of getting settled in the hide, we would
have the entire clan out and tucking into the peanuts with a
will! It took about five days of rain before the ground softened
up enough for the worms to return and normal watching to be
resumed.
Tawny
Owls
Watching
the Tawny Owls this year has been very frustrating. We have
a nest box behind the hide with both rear and front facing internal
cameras. Over the winter, as the old nest box had seen better
days, we decided take the opportunity to design and install
a box that we thought would supply better pictures. The new
box was duly installed in February, with its twin cameras, and
all was in working order. The female had no sooner started nesting
however, than the rear camera packed up!
Unfortunately,
nesting females can be so aggressive, that it was just not practical
to go back and replace the camera. We resigned ourselves to
not having any pictures of the (previously single) chick growing
up, making do instead with listening to their activity. What
we did not realise until after they had left the nest however,
was that unlike the last four years, there were two chicks rather
than one. If the camera had been working, we should have been
able to watch some incredible pictures. That, however, is wildlife
watching and we have to console ourselves that there will be
another year!
More
fighting !
Two
of our males have very recently been appearing with nasty wounds
on their faces. Kevin and Anne have both been getting more confused
about who is who amongst the males, apart from Alfred, who is
still easy to tell apart. We had just convinced ourselves that
the two wounded males were Scar (6-7 years old) and Hopalong
(9-10 years old) when another male appeared. This male was apparently
larger than either of the other two and promptly attacked the
one we thought was Scar. As Scar is the male who had previously
attacked Hopalong and nearly driven him out of the territory,
we had thought that the badger we had labelled 'Scar' this year
was responsible for the current fighting. Now we don't know
who the attacker is, Anne is keen to get a better view of this
other male. Even though we have been watching these badgers
for 7 1/2 years, they still amaze and surprise us!
Video
Diary updates
We
don't know quite what is happening with the video diary on the
BBC Nature website. We haven't been able to access the video
diary for a while now and have heard nothing from the BBC Natural
History Unit about further filming. We will be trying to contact
them about this. Meanwhile, if you want to see this year's clan
for yourself, you will just have to come and visit. We look
forward to seeing more of you here! Kevin and Anne.
2003
I must apologise
for having to start this update with a review of events in 2003.
For reasons which will hopefully not be repeated, Anne and I
only managed to post one update in spring, for the entire year.
Cubs
2003 saw
three of the four females produce a total of six cubs. It was
the first time so many had bred in one year. It might have been
luck, or had something to do with the mild winter. If anything,
this winter has been even milder, so it will be interesting
to see how many females breed this year.
Cubs, which are usually born in February, don't come above ground
until they are ten to twelve weeks old. While the cubs remain
below ground, the accepted view is that the females keep them
in separate places. We very strongly felt that we had two females
rearing their young within a few meters of each other, within
the same part of the sett. Unfortunately we were unable to confirm
this, which was very disappointing but, hopefully we will have
better luck next time it happens.
Weather
and food supplies
Despite
very dry weather conditions during two critical points of the
cubs' first six months (which would have resulted in very high
mortality for any clans not receiving supplementary feeding,
all six or our cubs survived to winter dispersal. The first
incident was a six week drought in early spring. This is a time
when the mothers need to reach their maximum milk production
levels to feed the cubs well. Their main food at this time of
year is earthworms, and these would have been forced deep underground
by the dry weather. The second, which was also a drought, occurred
when the cubs were trying to build up as much body reserves
as possible, ahead of winter.During the winter ,the adults often
force the cubs to go and find new territories for themselves.
This can be a very traumatic time for the youngsters and it
is believed that mortality is high even in normal years.
Clan
members
By the end
of last watching season Alfred, our dominant male, was still
the clan leader and was in very good condition. We will be keeping
our fingers crossed that despite his estimated age of 12 years,
he is still with us this year. Anne and I have just started
watching the badgers again in preparation for the new season,
we have not yet seen Alfred but Hopalong, two of the females
and at least two of last year's youngsters have been seen .
We will try to keep you more up to date on the family this year.
Webcam
After four
seasons of the BBC Natural History Unit's generous provision
of the badgercam we are very sorry to see it go offline. It
is regretable that not only are the BBC not able to withstand
the running costs any longer, we are certainly not able to.
So, we will all miss having the opportunity to see these badgers
from the comfort of our own armchairs, except for the glimpses
the BBC hope to bring you by way of occasional video diaries
on the BBC Nature website.
