Citizen Science
'Armchair’
birdwatchers have made a valuable contribution to our understanding
of what is happening to Britain’s birds, so say the authors
of an important study just published in a leading scientific journal.
BTO/CJ Garden BirdWatchers have been recording birds in their gardens
for a decade and their efforts have led to some exciting discoveries.
‘Citizen Science’
is the term coined by Americans to describe studies where members
of the public generate the data. The use of large numbers of ‘amateurs’
in this way has been dismissed by some in the past but is increasingly
being seen as an excellent way to collect quality information over
a large area.
10% of the UK’s
land area is associated with human habitation, and private gardens
form a significant part of this total. To put it in perspective,
more of the UK is garden than nature reserve. This means gardens
form an incredibly important habitat for birds and other wildlife.
Private gardens are notoriously difficult to survey for obvious
reasons. However, with the recruitment of an army of ‘citizen
scientists’ the BTO’s Garden BirdWatch survey has managed
to assess the importance of gardens for birds over the past decade.
Results from the BTO/CJ
Garden BirdWatch survey have just been published in the Journal
of Applied Ecology by scientists from the BTO and the University
of Sheffield. Entitled “Trends in the use of private gardens
by wild birds in Great Britain 1995–2002” the study
highlights worrying declines in species of high conservation concern
(e.g. House Sparrow, Song Thrush and Starling)(see Note 1). These
species have also suffered serious declines in other habitats. It
seems that what is happening in the wider countryside is being mirrored
in our gardens.
“This study demonstrates
how important the contributions made by ‘armchair’ birdwatchers
are to science and conservation. For most volunteers their interest
in birds doesn’t extend beyond the confines of their garden
but careful observation and recording, coupled with a sufficiently
precise survey technique, has provided a wealth of information for
scientific analysis” says Mike Toms, Garden BirdWatch organiser.
“The BTO/CJ Garden
BirdWatch study has only been possible because of the thousands
of people who give up a bit of time each week to record their garden
birds”, Mike adds. “We couldn’t survey garden
birds as well as we do were it not for this army of volunteer birdwatchers.”
The BTO needs more
people to record the occurrence of birds in their gardens. It has
been running its Garden BirdWatch survey since 1995. Some 16,500
participants currently take part in Garden BirdWatch and send in
simple weekly records of the bird species using their gardens. To

Notes for editors
1) In 1995 House Sparrows
were recorded in 83% of gardens, Song thrushes 37% and Starlings
79%. By 2002 this had declined to 72% for House Sparrows, 19% for
Song thrushes and 60% for Starlings.
2) The BTO/CJ Garden
BirdWatch. The BTO/CJ Garden BirdWatch is the only nationwide survey
of garden birds to run weekly throughout the year, providing important
information on how birds use gardens, and how this use changes over
time. Currently, some 16,500 people take part in the project. The
BTO/CJ Garden BirdWatch is funded by participants’ contributions
and supported by CJ WildBird Foods Ltd and is the largest year round
survey of garden birds anywhere in the world. For more information
see www.bto.org/gbw
3) Bird Table Magazine.
Bird Table magazine is published quarterly and sent free to all
BTO/CJ Garden BirdWatchers. An annual subscription to the project
costs just £12 and all new joiners will receive a free copy
of the BTO/CJ Garden BirdWatch Book (which normally retails for
£9.99). Electronic versions of the Bird Table articles are
available for Editors and can be requested from press@bto.org
4) Colour photographs.
Images of garden birds are freely available for use in association
with this press release. Please contact images@bto.org to request
an electronic version.
5) CJ WildBird Foods.
CJ WildBird Foods is Europe’s leading supplier of bird food
and bird feeding products. CJ WildBird Foods has been responsible
for a number of significant developments within the bird food and
feeding industry, including the introduction of black sunflower
seeds to the UK as a major new bird food and the development of
specialist seed mixes for use in tubular feeders. The company has
also been supporting research into the changing fortunes of garden
bird populations, most notably through the BTO/CJ Garden BirdWatch.
6) The BTO has an ISDN
line available for radio interviews.
