The gayal (Bos frontalis), also known as mithun or Drung ox, is a large semi-domesticated cattle in the Himalayan foothills of Indian Subcontinent and primarily in Northeast India. In his first description of 1804, Aylmer Bourke Lambert applied the binomial Bos frontalis to a domestic specimen probably from Chittagong.
In 2003, the International Commission on Zoological Nomenclature fixed the first available specific name based on a wild population that the name for this wild species is valid by virtue of its being antedated by a name based on a domestic form. Most authors have adopted the binomial Bos frontalis for the domestic species as valid for the taxon.
Phylogenetic analysis corroborates the taxonomic assessment that the gayal is an independent Bos species originating matrilineally from gaur, zebu and taurine cattle. There are two major hypotheses on the origin of the gayal:
It was domesticated from wild gaur; It is a hybrid descendant from crossing of wild gaur and domestic cattle, either Bos indicus or Bos taurus. Analysis of the genome of the gayal was published in 2017. In 2020, a phylogenetic analysis using complete mitochondrial genome sequences unambiguously... Wikipedia →

Possible
About 30% of wildlife watchers report a Gayal sighting in Khao Sok National Park on a given day, based on 30 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 7th most-seen of the 14 mammals 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.
June–July, September and November
In those months about 40% of wildlife watchers report a Gayal in Khao Sok National Park on a given day, against under 5% in August, the lowest month.
Between 11 am and 2 pm
Across all the parks we cover, that three-hour window holds the most Gayal sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
12th of 15
Of the 15 parks where we can rate Gayal sightings, Khao Sok National Park ranks 12th at about 30%. The best odds are in Kanha National Park (India, about 70%), Nagarhole National Park (India, about 70%) and Bandipur National Park (India, about 70%). All parks ranked.
Same order: Artiodactyla
The closest relatives of the Gayal that you can see in Khao Sok National Park (order Artiodactyla, Even-toed Ungulates and Cetaceans) are Wild Boar (about 20%) and Sambar (about 10%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Gayal is recorded against all the mammals logged in Khao Sok National Park (30 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.
