White-necked heron (Ardea pacifica)

The white-necked heron is a species of heron
that is found on most of the Australian continent wherever freshwater
habitats exist. It is also found in parts of Indonesia, New Guinea and
New Zealand, but is uncommon in Tasmania.
The populations of this species in Australia are known to be nomadic
like most water birds in Australia, moving from one water source to
another often entering habitats they have not previously occupied,
taking advantage of flooding and heavy rain where the surplus of food
allows them to breed and raise their young. The body size/length is between 76–106 cm. The diet consists of freshwater mussels, fish, shrimp, freshwater crayfish, spiders,
dragonfly nymphs, damselflies, praying mantis, grasshoppers, water
beetles, lizards, young ducklings, young freshwater rat, and amphibians.
