Thanks Chris, and others who responded to my
request, particularly Lindsay with his summary of the migration route that
travels over his house - some great and important detective work.
I'd be very happy to stand corrected, but it
appears this may now be the only significant route through the Canberra suburbs
compared with those elucidated in the 1980s and published in CBN. It seems
first the Pt Hut route was abandoned (perhaps for Lindsay's route?) and
then in turn the Angle Crossing one was abandoned soon after the January 2003
fires.
Perhaps it was already occurring but the fires do
seem to have had a major impact on their migration through Canberra suburbs (cf
much less impact further S eg between Michelago and Bredbo).
In my view this issue ought to be a priority for
COG and I'd be happy to help with/co-ordinate a more systematic survey next
year. Having helped with the surveys in the 1980s and having seen the
numbers migrating through then (as well as over my house in the late 1970s) we
should be very concerned - hopefully there's no Passenger Pigeon analogy
here!!
