There are indeed Barbary Dove in the SW suburbs of Adelaide as I saw 2 of them
today in Oaklands Road, Somerton Park.
Can someone outline the reason why this species is considered such a danger as
compared with, say Spotted Dove or Laughing Dove which are both introduced and
appear to do little harm (as far as I know). Birds Australia and the BIGnet
group of bird clubs in NSW are both working on policy guidelines for dealing
with what have been called overabundant or invasive bird species. In each case
there needs to be objective evidence that the species will cause damage to
native animals or plants or to human health before we go running off trapping,
shooting, poisoning or whatever. This evidence can be local or from overseas.
In the case of Canada Geese for instance there is abundant evidence fron the UK
and New Zealand. In the case of the Common Mynah there is much hysteria but
seemingly little scientific evidence of the damaging effect of this species. By
contrast the recent survey in the Capertee and Holly Parson's work in suburban
Sydney show the inverse correlation between species abundance and Noisy Miner
presence but there seems to be little concern among the public or birders.
