I
can’t believe that we are deep in the midst of autumn already, this year has
flown by. I’m sure they’re making these years smaller than they used to; just
like Wagon Wheels and Curly Whirlys, and Cadburys Crème Eggs for that
matter!
Arrivals and
Departures
Each
year in the Lake District, as well as bringing a stunning palette of
colours, autumn brings a range of
arrivals and departures in terms of wildlife. These migrations are
brought on by changes in the daylight hours and climate, not just in this part
of the country but across the whole of Northern Europe. These changes mean
that certain food sources become more scarce, vegetation and water bodies become inaccessible due to
snow and ice and wilder weather makes it desirable to find a more benign
environment in which to spend the winter months.
Bitter winds
A
previous Ranger blog mentions the house martins that nest under the eaves of the National Trust houses at Harrowslack
next to Lake Windermere. The real start of autumn for me is when they flock
together and decide to head South to Africa, usually connected to the first
cold snap, the bitter winds from the Arctic North giving a taste of what’s to
come. The signal for the house martins is the temperature drop but also the
increasing scarcity of their food source; flying insects.
Berries and seeds
The
departure of the house martins is followed in a few weeks by the arrival of Bramblings
and Fieldfares, birds that migrate from Scandinavia drawn to Britain by the relatively milder Winter
climate (compared to Norway and Sweden!) and the abundant seed and berry
crop from the likes of hawthorn bushes
and beech and rowan trees etc. Look out for flocks of these winter
visitors in the parkland around Wray
Castle. The bramblings look like chaffinches flying from beech tree to beech
tree, the Fieldfares similar to
blackbirds can be seen in the fields and around the hedgerows feeding on
berries, worms and insects.

Pink foot V formation
For
me one of the most thrilling spectacles at this time of year is the sight and
sound of flocks of geese flying in V - formation
overhead. Pink- footed geese breed in
Greenland, Iceland and Svalbard in the
summer, strangely, I always seem to see
them flying North in the winter and South in the spring. I am assured that this
is just the flocks making small movements to different winter feeding grounds, the estuaries, marshes and coastal fields around Morecambe
Bay and the Solway.

The
V formation in flight apparently helps create an updraft which reduces the
resistance and helps conserve energy.
Oystercatcher
Oystercatchers
are a familiar site on the shingle beaches around Windermere and Esthwaite
Water; they have a less dramatic migration. Like Curlews in the autumn/winter
they tend to head back to coastal areas; tidal beaches and muddy estuaries
provide a more reliable source of food than inland.
So
wildlife populations are always changing in the Lake District and there is
always something new to see as the seasons change. Wray Castle is open at the
weekends up until Christmas. Hill Top Shop and Garden is open every day (weather permitting). The countryside
in the South Lakes is open all year round - regardless of the weather. We'll look forward to seeing you in 'arrivals' soon!
