Wow, that is very few birds. I regularly see up to five birds on campus in the
mornings, particularly near where they are fed. I'm also surprised that none
were seen in Turner, as I regularly see them in Haig Park in the mornings on my
way to ANU. Last week there were four hanging around there together. I'm
wondering what is meant by "Turner North to Barry Dr." Barry Dr. is the
southern border of Turner, below which is ANU campus. Is it possible that two
people (me and however was doing "Turner") both surveyed the ANU campus?
Cheers,
