Hi Ralph, et
al
My most abundant home bird list species is Brown
Thornbill. As they are
in my garden often during the day this causes me
great anguish when
recording bird numbers for the BOCA garden bird survey.
Because I have no
way of knowing whether I am seeing the same group of
thornbills or different
groups I have opted for recording the number seen in
the largest group [not
that it is that easy to count thornbills!]. At
present the group size is
15 - 20. At other times of the year 6 -
8.
What do other people do?
Cheers
