The great argus or greater argus (Argusianus argus) is a large species of pheasant native to the jungles of Borneo, Sumatra and the Malay Peninsula in southeast Asia. It is known for its impressive plumage and courtship behavior. It is not to be confused with the two species of closely related crested argus, genus Rheinardia.
Carl Linnaeus gave the great argus its specific name (from which its common name and genus name are derived) because of the intricate eye-like patterns on its wings, in reference to Argus, a hundred-eyed giant in Greek mythology. There are two subspecies recognized: Nominate argus of the Malay peninsula and Sumatra, and A. a. grayi of Borneo. William Beebe considered the two races to be distinct species, but they have since been lumped.
The genus Argusianus was introduced in 1849 by the English zoologist George Gray with the great argus as the type species. The double-banded argus (Argusianus bipunctatus), known only from a portion of a single primary flight feather, was long considered a potential second species. It was described in 1871 from this feather piece, found in a millinery shipment imported to London. Its origin... Wikipedia →

Possible
About 20% of wildlife watchers report a Great Argus sighting in Khao Luang National Park on a given day, based on 132 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 70th most-seen of the 215 birds we can rate there. Over three days the chance rises to about 60%, and over a week to about 90%, if each day is a fresh chance.
August
In that month about 60% of wildlife watchers report a Great Argus in Khao Luang National Park on a given day, against about 10% in September and November–December, the lowest months.
Between 4 and 7 am
Across all the parks we cover, that three-hour window holds the most Great Argus sightings with a recorded time, and about half of them come between 6 pm and 6 am: it is most active around dawn and dusk.
2nd of 8
Of the 8 parks where we can rate Great Argus sightings, Khao Luang National Park ranks 2nd at about 20%. The best odds are in Danum Valley Conservation Area (Malaysia, about 40%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Great Argus is recorded against all the birds logged in Khao Luang National Park (132 verified sightings from 2019 to 2026), 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.
