I noticed a grey teal perched on top of a dead tree at Lake Wendouree. Does this duck nest in holes in trees, or does it make a nest in rushes or on islands?

The grey teal will readily use hollows in trees and logs for nest sites, but it will also make a nest on the ground, or in rock crevices.
Hollows seem to be preferred, probably because they offer more safety.
Nests on the ground are obviously more prone to predation by foxes, dogs and hawks, none of which would bother a bird in a tree hollow. All three could bother a teal nesting on the ground at Lake Wendouree.
In recently-flooded parts of inland Australia, the grey teal will flock to suitable places and make its nest virtually anywhere while food is abundant.
