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 Chitwan National Park on a given day, based on 15 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 13th most-seen of the 16 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.
March and April
In those months about 40% of wildlife watchers report a Gayal in Chitwan National Park on a given day, against under 5% in January–February, June–July and September–October, the lowest months. Those are among Chitwan National Park's driest months, with about 45 mm of rain a month against 660 mm in July.
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.
11th of 15
Of the 15 parks where we can rate Gayal sightings, Chitwan National Park ranks 11th 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 Chitwan National Park (order Artiodactyla, Even-toed Ungulates and Cetaceans) are Axis Deer (about 80%), Wild Boar (about 50%) and Sambar (about 50%), 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 Chitwan National Park (15 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.
