Nightingale Survey
Boom and bust - mixed news from
the 1999 Nightingale Survey
During the spring of 1999, over 1,000
BTO members and volunteers forsook sleep and surveyed more than
3,000 potential Nightingale sites. The survey has revealed some
surprising population trends for this much-loved songster.
The Nightingale population in Britain may be at a comparatively
low ebb in Britain at the moment but the 1999 Nightingale Survey
indicated that it was not all gloom and doom. In fact, we are delighted
to report that Nightingales appear to be doing well in some areas.
The preliminary total for the 1999 survey is 4,410 singing males
- only 8% less than reported in the last BTO Nightingale Survey
in 1980. While Kent held on to its position as the best Nightingale
county, the total of 861 singing males located in Suffolk was a
massive 135% higher than the 1980 total, resulting in Suffolk overtaking
Sussex as the second best county. Other counties within the core
range of Nightingale fared reasonably well with an increase in numbers
in Essex and only modest decreases in Norfolk and Sussex.
What
has emerged clearly from the 1999 Nightingale survey is that areas
towards the west of the species' range are faring less well. There
have been local extinctions in parts of Hampshire, Dorset, Somerset
and the home counties. Nightingales have been lost from over 20%
of the 10-km squares in which they were recorded in the 1980 survey
and more than 70% of territories are now concentrated in the four
coastal counties between Sussex to Suffolk.
In addition to the changes in the Nightingale's range, there has
been a noticeable shift in habitat use over recent decades. Once
a bird of woodland, especially coppice and young plantations, Nightingales
are now found predominantly in scrub with over half the singing
males found in 1999 residing in such habitats. The 1999 Nightingale
Survey has provided some important pointers to the future of the
species in Britain. The importance of scrub for this species serves
to place further emphasis on the conservation of scrubby habitats
for a wide range of species.

Thank you to all the volunteers who surveyed Nightingale sites
or sent in casual records. Many thanks also to the regional organisers
who were so effective in mobilising the large number of volunteers
involved. Finally, a big thanks to all those who contributed to
the BTO's Nightingale Appeal,
which provided funding for this survey.
