Self introduced from Australia the white-faced Heron is now the most common heron, having benefited from the widespread conversion of forest to farmland.
This slim bluish-grey heron has a white face, chin and upper throat, and a black bill and greenish-yellow legs. Strap-shaped plumes which form in the breeding season are long and pale grey on the back and short and pinkish brown on the chest. The call is a guttural croak.
The diet is fish, frogs and tadpoles, aquatic and pastures insects, spiders, earthworms and mice. ~ Bernard
