This is simply an overview of the instructions. Those wishing
to contribute should study the main document before proceeding
Please be sure that you have clearly identified your tetrad.
It is best to contact the organiser and get a photocopy of the
tetrad(s) that you wish to visit.
The Prime Aims of the Survey
1. To record the species within each tetrad
When: The fieldwork period is 1 December – 28
February
How: Simply record the species seen within the tetrad and using
the habitat during the fieldwork period.
Species need not be counted, but a recorder may encounter certain
species where they consider that a count may be useful or worthwhile
in the sense that it may represent a significant proportion of
the total number within the tetrad.
There is no time limit on this part.
2. To make an estimate of the population of each species in each
tetrad.
When: The fieldwork period is 1 December – 28
February.
How: Visit each tetrad for exactly 1 hour between 1 December
and 28 February inclusive.
Record all the birds that you encounter in your timed walk that
are within the tetrad and using the habitat.
