Sir Walter Scott's favourite view on the way to the Moss |
As we approach the
anniversary of V-E Day, it is as well to remember the huge
contribution made by the American G I's in the eventual victory.
Better dressed, better paid and more interesting to the local
lassies, they were often characterised as “over-paid, over-sexed
and over here” by their war weary British counterparts. After the
celebrations, “Yanks” returned home but another group of American
natives arrived from across the pond.
The ruddy duck
arrived.
The invasion began
in 1948 when the famed conservationist Sir Peter Scott’s love for
ducks led him to import three pairs of the colourful US birds to his
Slimbridge reserve in Gloucestershire but their escape and subsequent flourishing in the British countryside caused unforeseen problems.
The problem is that
the “sexy” male ruddy ducks (Oxyura jamaicensis) are preferred by
female white-headed ducks (Oxyura leucocephala) found in Europe, mainly in Spain. The resulting hybrid offspring threatened
the survival of the white-headed duck, which was already struggling
with habitat loss due to development. Ruddy duck males are
particularly aggressive when it comes to breeding and court females
more vigorously. This makes them more attractive to female
white-headed ducks.
Again, the local
lassies showed more interest in their American suitors!
The UK ruddy ducks
also spread their wings across Europe, into France, Belgium, the
Netherlands and into Spain. The discovery of hybrids in the latter
country in the 1990s showed the ducks had grown into a continent-wide
threat and that sealed their fate. A cull was demanded and undertaken at vast cost
making a dead ruddy duck the most expensive game bird ever.
Certainly, the numbers of ducks was reduced considerably but quite a
few still survive and their hybrid offspring must have bred several
times by now.
Bemersyde Moss |
Bemersyde Moss, an
SWT reserve, holds the dubious distinction of being the first place
in Scotland where the ruddy duck bred. None breed there now but the
shallow “kettle-hole” loch is home to little grebes, mute swans,
mallards and other wild fowl, reed buntings, and otters.
Little grebe |
For decades, perhaps even centuries, it was
the breeding site for thousands of Black-Headed Gulls, up to 14,000 –
yes, fourteen thousand- pairs were
recorded at one time.
Here, the
Black-headed Gull finds a congenial breeding place, and on
approaching the loch during the nesting season it may be seen on the
wing in immense numbers wheeling round and round in circles over
the swamp, while little can be heard but its incessant cackling
screams The nests, which are placed amongst the rough herbage of the
loch, are so numerous that it is said that upon one occasion as many
as sixty dozen of eggs were taken in a night by people from the
neighbouring farms, who sold them to the district carrier for 4d. per
dozen.
(The Birds of
Berwickshire - Muirhead 1895)
Suddenly,
in the early years of this twenty-first century, they vanished. No reason was ever
found. Some have now returned to breed but in greatly reduced
numbers.
The pickie-ma' as it is still sometimes called, is not a true sea-bird
and isn't even black headed, more of a chocolate brown colour and is
as common as crows but thousands of them at one time in one place
must have been a special sight. Maybe they will come again but not
the ruddy duck.
A companion in the hide ! |
