I'm currently running a Garden Bird Survey through the Queensland Ornithological
Society Inc, as a follow up to one I did twenty years ago. (Sunbird 25:1-17)
In the 1979/80 survey I had reports from 100 gardens and many of these had
lists for
over 50 weeks.
In the current survey I have records from nearly 70 gardens after only a
couple of
months so it looks as though we will have roughly comparable samples.
When the survey is complete, next year, I hope that we will be able to look
for changes
like this to the Qld suburban birds.
Yours
Peter
