The nankeen night heron (Nycticorax caledonicus) is a heron that belongs to the genus Nycticorax and the family Ardeidae. Due to its distinctive reddish-brown colour, it is also commonly referred to as the rufous night heron. It is primarily nocturnal and is observed in a broad range of habitats, including forests, meadows, shores, reefs, marshes, grasslands, and swamps. The species is 55 to 65 cm (22 to 26 in) in length, with rich cinnamon upperparts and white underparts. The nankeen night heron has a stable population size, and is classified as a species of least concern by the International Union for Conservation of Nature (IUCN).
The nankeen night heron was formally described in 1789 by the German naturalist Johann Friedrich Gmelin in his revised and expanded edition of Carl Linnaeus's Systema Naturae. He placed it with herons, cranes and storks in the genus Ardea and coined the binomial name Ardea caledonica. Gmelin based his description on the "Caledonian night heron" that had been described in 1875 by the English ornithologist John Latham in his multi-volume work A General Synopsis of Birds. The heron had been observed in September 1774 on the island of New Caledonia... Wikipedia →

Possible
About 20% of wildlife watchers report a Nankeen Night-Heron sighting in Makassar on a given day, based on 13 verified sightings from GBIF citizen-science data. It is the 31st most-seen of the 66 birds we can rate there. Over three days the chance rises to about 40%, and over a week to about 70%, if each day is a fresh chance.
Between 10 am and 1 pm
Across all the parks we cover, that three-hour window holds the most Nankeen Night-Heron sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 8 cities where we can rate Nankeen Night-Heron sightings, Makassar has the highest daily chance: about 20%. Next come Perth (Australia, about 10%) and Manila (Philippines, about 10%).
GBIF citizen-science records
It is estimated from how often the Nankeen Night-Heron is recorded against all the birds logged in Makassar (13 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.
