The good old Wood Duck certainly has worn out its welcome in many (all) golf clubs etc. I don't know why, after all the Woodies cut down on mowing and provide free fertiliser for the greens and fairways. It would be interesting to see if there are any differences in populations between the two atlases. I had a quick look on BA's Birdata and there does not seem to be much of a difference, but then the atlases only give an approximation of actual populations

I dont think we should restrict that observation to Kangaroos.
I reckon we have a pretty adaptable "goose" of our own in the Australian Wood Duck, Chenonetta jubata. It seem that there are not too many farm dams or golf courses with water hazards that dont support a pair (or flock). I am not sure if we have historical Atlas records that support my personal view that they have exploited the man made environment of water plus good grazing very successfully indeed.
