I've
always liked the London Underground, from the woosh of the trains to
the unique aroma of the platforms, and especially the schematic map.
When I worked in a microbiology lab in London in the 1970s, I always
got a seat on the tube by the simple expedient of donning a lab coat
and carrying a sandwich box covered in biohazard stickers. We don't
have an underground here in Cockermouth (nor an overground any longer
thanks to Dr Beeching), but I've adopted the schematic map to plan my
local walks. Welcome to the Circle Line, starting at my local
station: The Old Cornmill.
I
haven't mentioned the height of the River Derwent recently, mainly
because it has been behaving itself and not causing me to deploy the
flood defences. After a weekend of steady rain (which, for the first
time in five months, prevented me getting out and about) it rose to
its typical high level which is not enough to worry the mallards. So,
let us proceed eastbound, stopping first at Back Lane.
Here
we find a wall covered in dying ivy, which gives
us a chance to have a good look at how it manages to grow up a wall
without falling off. Firstly, it sends out small roots from the stem
to get an initial purchase. These then send out even smaller rootlets
that get into the tiniest of crevices and produce an adhesive (with
separate hardener, would you believe). Finally, they change shape,
screwing themselves into position, then lignify (turn to wood). So,
if you want to affix something permanently to a wall, copy ivy –
glue it, then screw it.The scientific name, Hedera helix, means grasping and spiralling. They didn't know about the glueing back then.
Turning
our back on the ivy and peering over the opposite wall we have an
uninteresting factory (from a naturalist's point of view) fronted by
a pair of interesting reservoirs. There's usually something to see
here, and today is no exception. Over there on the far bank (where
else?) we have an Oystercatcher. I usually see these running along
the sea shore, at the water's edge (see A
Fjord By Any Other name - Solway Firth)
and most Oystercatchers
around the world are, indeed, coastal birds. The European
Oystercatcher however, along with a couple of other species, also
breed inland.

Our
next stop along the line is North Fields (change here for the
Northern Line to Woodhall farm) with a view of Cockermouth Castle in
the distance and the landmark King's Church spire. We also have a
flock of Herdwicks, and where we have sheep we have dung. Time for a
prod! I see that the Yellow Dung Flies have hatched and are busy
making the next generation. And if we turn it over... that looks to
be a little dung beetle burrowing its way into the warm goo. Quite
possibly an Aphodius
species such
as we saw at Watendlath
Tarn.
We're going to continue our journey to the bottom left corner of the
field. Next stop, Gote Mills race.

I
explained all about Gote Mills Race last year in Down
By The Derwent, so
I won't go over it again. The sluice gate is closed so let's delve
beneath the logs lying amid the Snowdrops and see who's home. There
are a couple of small snails, very delicate and shiny, so I expect
that they are Glass Snails of the Gastrodontinae family; a Shiny
Woodlouse, Oniscus
asellus, and
a pretty little Arion
slug. I must admit, I was hoping for the odd reptile or amphibian down
here but no matter, every living thing has an interesting tale to
tell. No room to tell them here, but if you subscribe to Steve's
Nature Plus I
often go into more detail about the lifestyles of our native
creatures.

Last
stop, Memorial Gardens. We're back in civilisation now with plenty of
garden feeders in the area so we have a good number of birds, such as
this Blue Tit, singing in the trees. I do believe that was a Red
Admiral butterfly we just disturbed, and over there – our first
Bumblebee of the year. The insects are starting to appear, birds are
singing for mates and it's the Equinox at 9.37am on Saturday. Spring
begins this week-end. Yippee!
With
all these insects and other invertebrates beginning to appear, why
not treat yourself to a copy of The
Quick Guide To Creepy-Crawlies and find out more about the
amazing world of the minibeasts.
Happy
Springtime
