An impressive record of conscientiousness and
consistency from Michael. To put others in the picture, that means that for the
first 21 years alone (we are now into year 24), Michael's site had 861 separate
count observations of Silvereyes (page 114 of the GBS Report, Site 15).
I also reported I think with disbelief at the first
week ever that I didn't have Starlings and they have declined although that is
probably die to other factors, mainly the Myna and less irrigation of sports
grounds.
Rosemary asked a very good question. "Is there evidence of a decline in 'small' bird numbers as a
result of the removal of habitat in the name of "fire-hazard-removal"?
We are in the unique position to be able
to go somewhere towards answering this, though it will take several years. The
GBS results show that you can't make too much of any one or even two or
three years' data. We need several years of data to come up with any
believable result. That is why the compilation task for the first 21 years was
done.
