Pink-eared duck Malacorhynchus membranaceus an endemic bird, can be found in anyplace in Australia especially after rain, but they are over-wintering in Melbourne. Question is why? The small wetland was fenced-off from dogs/humans etc but was full of pacific black ducks and hard-heads. Guesstimate; 1000
How can so many birds find enough forage in such a small an area, is it because things are even more difficult inland? Is this species over-abundant outside the city. Or are city environments attractive in some way?
