Hi birders,
Thanks Peter. I like you idea about reporting mass flocking, large scale
migrational movement, mass breeding events on Birdline Australia. Interestingly
(for this very reason) I have just put up a record of large numbers of Flock
Pigeon in Bowra, Queensland.
A good example of the sort of thing you are talking about was the large number
of Oriental Pratincole at Eight Mile Beach (FN Western Australia) in February
2004. For example on a bird count, conducted by Frank O'Connor and Clive
Minton, they calculated that there were 2.88 million birds! The previous
estimate for the entire East Asian-Australasian flyway was just 75,000 birds.
Also I would suggest the congregation of Banded Plover, Australian Pratincole
and Inland Dotterel near Terrick Terrick NP (Victoria) in November 2007 would
qualify for national reporting.
Thanks,
Tim Dolby

Subject: RE: Birdline Australia Reporting, Bird migration and Breeding events
A few recent threads got me thinking about a possible use for the Birdline
Australia reporting website. (the new national one, rather than the state
one)
Everyone that watched the Land of Parrots program would have thought
"gee..i'd love to see that many budgies flying around". And if such a
breeding event was recorded, i'd imagine quiet a few people would like to
travel to see it. Some people might prefer to go and see something like
this, rather than twitch a ship-assisted house crow. ; )
So if people observe any mass flockings of birds, whether as a case of
environmental changes (floods attracting waterbirds), potential
migrational movements, mass breeding events or gatherings for partner
selection etc, then they could be reported to Birdline Australia, even
if the species is a common one. Even just general large-scale
environmental changes could be recorded too, such as bushfires, floods and
droughts. This might turn into a valuable research tool. For example, if
budgies turn up towards the edge of their range in Southern Victoria, and
6 months beforehand an innundation occurred in the Northern Territory
resulting in a breeding explosion, then we might be able to peice together
a legitamate reason why budgies are now turning up in Southern Victoria.
etc.
I'm not sure if this type of reporting occurs much, but i think most
people usually just report threatened or out of range species.
