Rare
Under 5% of wildlife watchers report a Black-tailed Crake sighting in Manas National Park on a given day, based on 29 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 268th most-seen of the 377 birds we can rate there. Over three days the chance rises to about 10%, if each day is a fresh chance.
November
In that month about 10% of wildlife watchers report a Black-tailed Crake in Manas National Park on a given day, against under 5% in December to October, the lowest months. That is one of Manas National Park's driest months, with about 10 mm of rain against 1070 mm in June.
Between 3 and 6 pm
Across all the parks we cover, that three-hour window holds the most Black-tailed Crake sightings with a recorded time, and about 8 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Only Manas National Park, in our data
Manas National Park is the only park on Wallace's Line with enough records to rate Black-tailed Crake sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Black-tailed Crake is recorded against all the birds logged in Manas National Park (29 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.
