Thank you very much for offering to collect information on the birds 
of your area using ’Birds of the Central Wheatbelt of Western 
Australia - a checklist’. 
The INTRODUCTION on pages 1 and 2 of the checklist explains the 
purpose of the checklist and the sort of information required. It 
would be worthwhile circling the habitat code which describes where 
you observe each species. For example, you may only see a species in 
woodland in which case you would put a circle round W in the Habitat 
column against that particular species. There is a map in the centre 
of the checklist and it shows the area over which the checklist 
is probably most accurate. Those observers who are out of this 
area are most likely to see species which are not listed the 
further they are from the area of the map. In some cases the 
status of the species may differ; for example, they may be 
resident in the district and not a non-breeding migrant. If you 
are observing within the area of the map in the checklist please 
mark out the area over which you are collecting information. If 
you are outside this area please print on the back cover of the 
checklist a precise location of your observation area so that I 
can locate it when the data are being collated. Please write 
your name and addresss on the checklist and please note prominently the 
date you start collecting data as 5 months of this year have nearly 
gone. 
At the end of the year I will send a new checklist out to you together 
with an envelope to allow you to send your completed checklist to me. 
I will photocopy it and return the original to you if you would like 
to keep it. I will then analyse the data to establish the 
distribution of species and any changes in occurrence with season. I 
will keep you informed of the progress of the report.
