Thanks Tony,
I have spoken with both BA and BOCA today and they will make separate
representations to the SA government in coming weeks. I have also suggested
we do something about the birds at Williamstown here in Melbourne if we are
going to get all high and mighty about the birds in Adelaide.
The message that needs to be got across to people is that Barbary Dove is a
domesticated line almost certainly derived from African Collared Dove
Streptopelia roseogrisea, which inhabits sub Saharan Africa and Arabia. So
once these birds start wild breeding environmental pressure will selectively
revert them back to a wild type and it would probably happen quite quickly.
How quickly they might then venture out from Adelaide is anyone's guess.
The Laughing Doves in Perth are still restricted to the South West region
but it can't be assumed that this will remain the case, as long as they are
there they are being molded by their surroundings into more suitably adapted
organisms expanding their diet selection and they may eventually reach a
state of perfection which allows them to expand else where . As an example
of a reversed situation I can still remember back in the sixties when Galahs
first came into the suburbs of Melbourne. They were feeding on Liquid Amber
seeds amongst other food sources which have always been there but it took
then two hundred years to finally venture into this foreign environment and
eat novel food sources. Both Laughing Dove, which we can't now do anything
about and African Collared Dove are well designed for most of inland
Australia, so adding one more genetic model into picture is just asking for
trouble. What happened in Alice Springs is a small example of how quickly
this can take off from apparently harmless beginnings.
Cheers Jeff.

Jeff, I doubt very much if anyone knows the whole situation and what is
known seems to change frequently. For myself I know of several locations
where they have been seen, ie Sampson Rd area in Elizabeth ( Mike Carter
reported up to 12 here although I've never seen that many), Roscommon Rd in
Salisbury Downs still has three or four to my knowledge, there used to be a
pair in the street outside the Port Adelaide Football stadium but I don't
believe they've been reported there for some time - whether they are still
there I don't know. Apart from that there are some other reports in other
suburbs posted by other people ( i.e. David Kowalick today) , but as I said
earlier, I doubt whether anybody has attempted to collate comprehensive data
on them. For instance , has anyone reported them to Birds Aust for inclusion
in the Atlas and might that be starting point? And if Birds Aust know
about them what are they doing about it? At best they've talked to Birds SA
and we already know how excited they must be about the problem because
nothing much has happened. As for local " authorities", as I said earlier
today, they are probably each expecting someone else to fix it claiming a
lack of resources.
BTW, DW's report of them must be additional to Salisbury and Elizabeth
because these are northern, not South Western suburbs.

Are you able to give us some background on the situation there Tony, because
this has caught a lot of us by surprise. How many birds at how many
locations are there? Postings on birding-aus over the last couple of years
left me thinking it was a small population based on a handful of birds
living across a couple of backyards in one suburb, not that I was
particularly happy about it, now it's obviously something bigger, how was it
allowed to happen.
Jeff.

I'm pretty sure Birds SA know about it, after all, it's their membership
showing interstate tickers where they are. But as I said before, it's
already going to be a big job to get rid of them and nobody wants to take it
on. I guess DEH say it's a council responsibility and vice versa. I can
understand eradication being successful at The Alice though because it's a
much smaller area to cover. I can just see the tourism ads now - " come to
sunny Arkaroola and feed the beautiful doves" T -----Original Message-----

G'day Tony, David and Trevor,
Is Birds SA really on to it?? If they are what is happening? They should be
giving the relevant government department plenty of grief over this until
something is done. Who wants to take bets on how long it takes for them to
reach Arkaroola.

There are some other small populations in Salisbury and Elizabeth. I'm sure
the authorities know about them but nothing is being done to eliminate them
- I think they are more or less accepted as inevitable. They've been there
for some time now.

These locations should be reported to the relevent authoraties especially if
they are breeding so they can be removed while they are still domestic
stupid and not street smart.
Cheers Jeff Davies.

Hi All,
Re : Barbary Doves in Adelaide I have found three new locations where
there seem to be breeding populations of BDs in the South Western
Suburbs. They are fairly consistently seen in the same locations and all
up number over 20 birds. For anyone looking for an inglorious tick happy
to give directions.
Cheers
Dave K
