I agree that it looks like a genuine drop, and from your graph yesterday, a widespread one.
Hopefully some of the biologists in this group will be able to suggest reasons for this. The kite I would fly is to note that one of the problems with Spotted Doves invading Alice Springs was their competition with the native pigeon species.
