There are two subspecies[1]:

  • E. n. novaehollandiae:
  • E. n. parryi:

Adams (2013) recognizes the smaller race E. n. nana confined to New Caledonia and the Loyalty Islands[4]. However geographic variation is slight and most authorities consider the species to be monotypic[6].

Habitat

Lakeshores and riverbanks, mangroves, shallow lagoons and on tidal mudflats and estuaries, sometimes rocky shores.

Behaviour

Breeding

The nest is an untidy shallow bowl, constructed from sticks and usually placed on a leafy branch.

Diet

They have a very varied diet, consisting of fish, aquatic insects, amphibians, and in New Zealand they take the introduced Tree Frog.

Vocalisations

Common call is a graak or graaw given in flight, during intraspecific interactions.
