There is an attached page - the Bittern Chronicle.
http://www.birdsaustralia.com.au/images/stories/current-projects/bittern/BitternChronicle_Aug09.pdf
That page goes on to report some 32 sightings of the Little
Bittern, and no mention is made of the reports of any sightings in
Canberra. In view of the traffic earlier this year on this
forum about Little Bitterns, that seems odd to me.
"There is no available population estimate for this species; in
2008, deliberate searches for bitterns at many wetlands throughout southern and
eastern Australia, organised by Birds Australia, uncovered a total of just 32
Australian Little Bitterns."
Sounds to me like COG members could help set that
record straight somewhat.
