FREEZING
CONDITIONS HEIGHTEN DISTURBANCE THREAT TO WETLAND BIRDS
For the first time
in over a decade, nature conservation bodies are today [Tuesday 6 January
2009] calling on birdwatchers, walkers, anglers and water sports enthusiasts
across Britain to minimise disturbance to groups of ducks, geese, swans
and wading birds. On lakes, rivers, wetlands, and coastal areas the
birds will be struggling to survive after enduring seven consecutive
days of freezing temperatures.
The group making
today's call include the RSPB, the British Trust for Ornithology, the
Wildfowl & Wetlands Trust and Natural England.
Following a run
of mild winters, this is the first time in a decade that this call has
been made in England. An appeal in Scotland was issued in 2003.
Dr Mark Avery, the
RSPB's conservation director, said: "During freezing conditions
disturbance forces the birds to squander their precious energy reserves
by taking flight when they need to spend as much time as possible feeding.
"Although we
haven't made this appeal since 1997, we hope everyone who uses the countryside
will heed our advice, allowing the millions of birds which visit the
UK's coasts and wetlands during the winter to stand a better chance
of survival."
If the severe weather
continues for 14 days in succession, the shooting of some species of
duck, geese, and wading bird can be suspended for a fortnight to help
the birds recover. The last time such a ban was imposed was in 1997.
The birds affected
include ducks - including wigeon and pintail - and wading birds, such
as godwits, dunlin and knot. These birds either nest in the Arctic,
or further north or east in Europe. During the winter the birds visit
the UK to escape harsher conditions further north.
Dr Andre Farrar,
the RSPB's protected area campaigner, said: "Even at a time when
our climate is warming, we can still expect freezing conditions, but
less frequently. Wildfowl and wading birds respond to these icy blasts
by moving further south and west. Mild winters have allowed some of
these international travellers to cut short
their journeys, with more remaining within the eastern half of Britain.
"As the natural
world responds to the freeze, we can expect the UK's vital coastal wetlands
to play a role in helping these hardy birds survive the winter. If the
freeze continues, we can expect the warmer estuaries on our west coast
- such as the Severn, Dee, Mersey, Ribble, Morecambe Bay and the Solway
- to be especially important as birds escape the weather. These are
amongst our most important wildlife sites. The winter of 2009 is likely
to show just how vital they are to the survival of thousands of water
birds."
