The instructions for the survey are shown below but can be downloaded by clicking here.
Submissions can be made via the BTO Atlas website or by entering data
into an excel spreadsheet and e-mailing or posting it to Steve White or Bob
Harris.

With a couple of minor exceptions, the methodologies of the
national and Lancashire surveys are identical.
Timed Tetrad Visits (TTV)
The BTO requires a minimum of two 1-hour visits to each
surveyed tetrad during each season during which all birds seen or heard should
be counted, although they would prefer two 2-hour visits where possible. If you
choose to carry out two 2-hour visits, please read carefully the instructions on
the TTV form.
We need to ensure that we fulfil the BTO’s minimum
requirements in Lancashire but need to do rather more. Although it is not
essential to carry out TTVs in all tetrads it would be very useful to do so.
Further visits to tetrads
The BTO minimum of two 1-hour visits is unlikely to be
sufficient to identify and assess the breeding status of all species in each
tetrad, although these will produce crucial data to enable the BTO to make
comparisons with previous national atlas surveys.
Additional visits should concentrate on producing full
species lists for each season and confirming breeding status rather than on
counting birds. You should cover the full range of habitats in each tetrad.
The minimum requirement for the Lancashire survey is two
2-hour visits per season but there is no upper limit to the number of visits you
can make – the more the better.
In addition to the BTO requirements we ask you to count
some of the scarce breeders of the county (see below). Please note that, while
the list might look long, in actual fact relatively few of these species will
occur in any one tetrad.
Additional records
All records of birds seen anywhere in the county during
winter (November to February) or summer (April to July) for the next four years
will be used for the atlas surveys.
So, surveyors are also asked to submit records from outside
their tetrads.
Population estimates
In addition to the timed counts, the BTO is asking
surveyors to estimate the total number of birds they think are present in each
tetrad. This is optional but we would encourage you to attempt this task for as
many species as possible.
Please note that the BTO require counts (both for TTVs and
population estimates) of individuals (excluding known juveniles).
In addition to this, we are asking
surveyors in Lancashire to try to count the number of pairs of a selected
list of scarce breeding species (see separate sheet).
We hope that this does not cause confusion. To take an
example: if you are lucky enough see 3 male and 1 female Whinchats in your
tetrad, this would be logged as 7 birds for the BTO’s purposes but probably just
3 pairs for Lancashire’s. Please do both.
SUBMITTING YOUR RECORDS
Please try to submit your breeding season (April to July)
records before the end of August, and winter (November to February) records
before the end of March each year.
Records can be submitted in three
ways:
Timed Tetrad Visits (plus
additional hours on the day of the TTV)
v Online, directly onto the BTO website ‘Timed Tetrad Form’ at www.birdatlas.net
v By post on the BTO ‘Timed Tetrad Form’ to your local or regional,
who will pass them on to the BTO.
v By email on the ‘Lancashire Tetrad Form’ to your local or
regional, who will pass them on to the BTO.
Additional visits to your tetrad
v Online, directly onto the BTO website ‘Roving Record Form’.
v By email or post on the ‘Lancashire Tetrad Recording Form’ to your
local or regional organiser, who will pass them on to the BTO.
Additional records from outside your tetrad
v Online, directly onto the BTO website ‘Roving Record Form’.
v By email or post on the ‘Lancashire Roving Records Form’ to your
local or regional organiser, who will pass them on to the BTO.
Please note: the BTO only
requires these records at the 10km square although submission at the tetrad
level is optional.
In Lancashire we need ALL records
at the tetrad level.
Recorders may find it
easier to log ‘casual’ records as 6- or 4-figure grid references or by site name
rather than work out which tetrad they refer to. In which case, please send them
on the ‘Lancashire Additional Records Form’ to your local organiser or to the
County Recorder, even if you are using the BTO website (which won’t accept full
grid references) for the bulk of your recording.
Lancashire Count Species
The BTO will not be making use of counts of breeding pairs
of scarce breeding species and they cannot be entered on the BTO website. So
please send these:
v By email or post on the ‘Lancashire Tetrad Recording Form’, to
your local or regional organiser.
DON’T BE DAUNTED!
We realise that all these instruction sheets and forms may
look more than a little confusing at first sight but the surveys are actually
pretty straightforward.
The main information on how to carry out the surveys is
contained in the BTO material.
If in doubt, contact your local or regional organiser.
