In 3 days ~50% in a week ~80%
Troides minos, the southern birdwing, also called Sahyadri birdwing, is a large and striking species of swallowtail butterfly. It is endemic to southern India. With a wingspan of 140–190 mm, it is the second largest butterfly of India. It is listed as Least Concern in the IUCN Red List.
It was earlier considered a subspecies of the common birdwing (Troides helena) but is now recognised as a valid species. The species is more common in the Western Ghats of southern India, which is a biodiversity hotspot with a high degree of endemism in many taxa. It is much sought after by collectors and is a highlight of many butterfly tours in the Western Ghats. It is the state butterfly of Karnataka, India.
Description from Charles Thomas Bingham (1907) The Fauna of British India, Including Ceylon and Burma, Butterflies. Volume II. Male and female. Differs from Troides helena cerberus as follows. Male: Hindwing: the black along the dorsal and terminal margins both on upper and undersides much broader; on the upperside entirely filling interspace 1, on the underside with only a narrow streak of yellow at the angle between the median vein and vein 2; the cone-shaped black markings...

Possible
About 20% of wildlife watchers report a Southern Birdwing sighting in Periyar National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 31st most-seen of the 44 insects 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.
August
In that month about 50% of wildlife watchers report a Southern Birdwing in Periyar National Park on a given day, against under 5% in March–July, September–October and December, the lowest months. That is one of Periyar National Park's wettest months, with about 410 mm of rain against 15 mm in February.
Between 2 and 5 pm
Across all the parks we cover, that three-hour window holds the most Southern Birdwing sightings with a recorded time, and nearly all of them come between 6 am and 6 pm: it is a daytime animal.
Only Periyar National Park, in our data
Periyar National Park is the only park on Wallace's Line with enough records to rate Southern Birdwing sightings: about 20% of wildlife watchers there report one on a given day.
Same family: Papilionidae
The closest relatives of the Southern Birdwing that you can see in Periyar National Park (family Papilionidae, Swallowtails and Parnassians) are Paris Peacock Swallowtail (about 30%), Common Mormon Swallowtail (about 30%) and Red Helen Swallowtail (about 30%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Southern Birdwing is recorded against all the insects logged in Periyar National Park (6 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.
