Carl,
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.
