The striated heron (Butorides striata) also known as mangrove heron or little green heron, is a small heron, about 44 cm tall.

He placed it with the other herons in the genus Ardea and coined the binomial name Ardea striata. Linnaeus specified the locality as Suriname.

The striated heron is now one of four closely related species placed in the genus Butorides that was described in 1852 by the English zoologist Edward Blyth.
This bird was long considered to be conspecific with the closely related North American species, the green heron, which is now usually separated as Butorides virescens, as well as the lava heron of the Galápagos Islands (now Butorides sundevalli, but often included... Wikipedia →

With luck
About 10% of wildlife watchers report a Striated Heron sighting in Hangzhou on a given day, based on 171 verified sightings from GBIF citizen-science data. It is the 67th most-seen of the 219 birds we can rate there. Over three days the chance rises to about 20%, and over a week to about 50%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Striated Heron in Hangzhou on a given day, against under 5% in October to March, the lowest months.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Striated Heron sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
61st of 146
Of the 146 cities where we can rate Striated Heron sightings, Hangzhou ranks 61st at about 10%. The best odds are in Salvador (Brazil, about 60%), Antananarivo (Madagascar, about 50%) and Fortaleza (Brazil, about 50%).
Same family: Ardeidae
The closest relatives of the Striated Heron that you can see in Hangzhou (family Ardeidae, Herons, Egrets, and Bitterns) are Little Egret (about 60%), Black-crowned Night Heron (about 50%) and Grey Heron (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Striated Heron is recorded against all the birds logged in Hangzhou (171 verified sightings), calibrated against known sighting rates. Figures are rounded to the nearest 10% because citizen-science data supports honest approximations, not decimals, and months with records from fewer than five people show "—". How it works.
