Acridotheres tristis
In 3 days ~50% in a week ~80%
The common myna or Indian myna (Acridotheres tristis), sometimes spelled mynah, is a bird in the family Sturnidae, native to Asia. An omnivorous open woodland bird with a strong territorial instinct, the common myna has adapted extremely well to urban environments.
The range of the common myna is increasing at such a rapid rate that in 2000 the IUCN Species Survival Commission declared it one of the world's most invasive species and one of only three birds listed among "100 of the World's Worst Invasive Species" that pose a threat to biodiversity, agriculture and human interests. In particular, the species poses a serious threat to the ecosystems of Australia, where it was named "The Most Important Pest/Problem" in 2008.
In 1760, the French zoologist Mathurin Jacques Brisson included a description of the common myna in his Ornithologie, based on a specimen that he mistakenly believed had been collected in the Philippines. He used the French name Le merle des Philippines and the Latin Merula Philippensis. Although Brisson coined Latin names, they do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature.
When...
Possible
About 20% of wildlife watchers report a Common Mynah sighting in Khao Sok National Park on a given day, based on 183 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 52nd most-seen of the 215 birds we can rate there. Over three days the chance rises to about 50%, and over a week to about 80%, if each day is a fresh chance.
July
In that month about 40% of wildlife watchers report a Common Mynah in Khao Sok National Park on a given day, against about 10% in March and May, the lowest months.
Between 8 and 11 am
Across all the parks we cover, that three-hour window holds the most Common Mynah sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
25th of 32
Of the 32 parks where we can rate Common Mynah sightings, Khao Sok National Park ranks 25th at about 20%. The best odds are in Udawalawe National Park (Sri Lanka, about 80%), Yala National Park (Sri Lanka, about 70%) and Kanha National Park (India, about 70%). All parks ranked.
Same order: Passeriformes
The closest relatives of the Common Mynah that you can see in Khao Sok National Park (order Passeriformes, Perching Birds) are White-rumped Shama (about 60%), Black-crested Bulbul (about 50%) and Pin-striped Tit-Babbler (about 50%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Common Mynah is recorded against all the birds logged in Khao Sok National Park (183 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.
