Physical description Click here for a physical description Striated Herons are small herons with a grey back and a brownish, striated front. Their cap is black, with a black nuchal crest. The eyes are strikingly yellow. The bill is dark-grey. The legs have a greyish-yellow front side and yellow back side. Juveniles have a highly cryptic dark-brown plumage with lighter brown striation that gradually changes into adult plumage.

Taxonomy, classification See Striated Heron at Wikipedia . Click here for classification information The Striated Heron is no longer considered to be conspecific with the Green Heron ("Butorides virescens") found in North America.

Range, habitat, finding this species Click here for information on habitat and range The overall distribution of this species can be assessed, and specific locations where birds have been spotted can be found, based on individual sighting reports submitted by birdwatchers to ebird.org . The global distribution of the Striated Heron is available HERE . There are at least 3 races of Striated Herons, which are a sedentary species of small herons found in tropical and subtropical wetlands of Europe, Africa, Arabia, the Indian subcontinent, Asia, Oceania, Australia and South America. There are two races of Striated Herons in Australia. They are found in a narrow coastal strip around the northern half of the Australian continent, from about Exmouth, WA, via the North coast to the South-East coast (NSW, to about the border with VIC). From the longitude of Mt. Isa, eastward along the coastal fringe, race "macrorhyncha" is found; westward of that longitude race "stagnatilis". Race "stagnatilis" will venture a bit further inland along the major rivers of the western Top End of the NT and the Kimberley coastline than Striated Herons anywhere else on the continent. As their alternative name already suggests, they favour mangrove swamps and tidal flats as their habitat.

Sightings Click here for sighting information Race "macrorhyncha" A Striated Heron, race "macrorhyncha", was first seen by us in Australia in an intertidal wetland, in a mudflat at the Urunga board walk, Urunga Heads, NSW, in January 2011. Since then they are found by us and our contributors regularly at the same location. Subsequently Striated Herons, race "macrorhyncha", were also seen on various occasions in the Hunter Wetlands NP, in the estuary of the Hunter River near Newcastle, NSW. D. Wilczynska reports spotting a Striated Heron, race "macrorhyncha", at Cape Tribulation, Daintree NP, QLD, in March 2015. J. Greaves spotted a Striated Heron, race "macrorhyncha", as far South as Otway, Sydney, NSW, in July 2015. M. Mearns reports spotting a Striated Heron, race "macrorhyncha", at Paradise Dam on the Burnett River, East of Gayndah, QLD, in April 2016. M. Mearns also spotted a Striated Heron, race "macrorhyncha", at Leichhardt Falls, QLD, in September 2019. M. Eaton found Striated Herons, race "macrorhyncha", semi-regularly in various wetlands along the coastline of QLD, including King Island, Moreton Bay, QLD, where one was found in January 2020. J. Boettcher, FNQ Nature Tours reports spotting a Striated Heron, race "macrorhyncha", on the Daintree River, QLD, in October 2019. Race "stagnatilis" B. Hensen reports spotting Striated Herons, race "stagnatilis", semi-regularly in and around Darwin, NT. J. Greaves reports spotting a Striated Heron, race "stagnatilis", at Roebuck Bay, WA, in April 2015. P. Brown reports spotting Striated Herons, race "stagnatilis", semi-regularly in various intertidal wetlands in and around Darwin, NT. P. Brown also found a Striated Heron, race "stagnatilis", on the Victoria River in Timber Creek, NT, in November 2018. Only birds found in the region of Katherine, NT, are found farther from the coastline. Race "brevipes" We have spotted a Striated Heron, race "brevipes"(?), in Oman.

Usually there is no visible distinction between breeding and non-breeding plumage in Striated Herons. However, for a short period near the peak of the breeding season (around the time for mating to egg-laying), they can show signs of a nuptial flush. The lores can turn orange to red and the legs and feet can also turn red.
