Probably the most famous inhabitants
of Sliabh Mannan, considerably more famous than your present
correspondent, are the overwintering Taiga Bean Geese (anser
fabalis).
There are only two regular wintering
grounds for this species in the UK, the other being in Norfolk. The
Sliabh Mannan bean goose population consists of about 250 birds and
has been carefully monitored since 1992. In 2008 the area was
protected under the EU Birds Directive. This year a tracking study,
in which local schools participated, found that the summer home of
our geese is northern Sweden. For some reason I had been convinced
that they came from Russia, which shows you how little of the bean
goose language I really understand.
"Honk!"
"You've been saying that since
Spitzbergen!"
Honk!"
It
is of course a very loud language, particularly when flights of well
over a hundred birds pass overhead together in their characteristic
V-formations. This autumn, if I interpret my records correctly, I
saw my first bean goose flight on 27 September. For
several days I was being confused by a smart rook who went around
imitating goose calls and making me believe that they were early.
From time to time in my winter
wanderings I come across hopeful twitchers equipped with
binoculars and a great deal of optimism. Around my home we have
never seen the birds on the ground, but overflight is common. I
get the impression that training flights build up in the new year,
prior to the spring departure. Well, it's a long way across the
North Sea, you know!
"So, does that mean we're nearly
there, then?"
"Honk!"
