The white-tailed flycatcher (Leucoptilon concretum) is a species of bird in the family Muscicapidae. It is the only member of the monotypic genus Leucoptilon. It is found in submountain forests from the eastern Himalayas and northern Myanmar to southern China, western and southern Thailand, the Malay Peninsula, Sumatra and Borneo.
The white-tailed flycatcher was formally described in 1836 by the German naturalist Salomon Müller based on a specimen collected in the interior of the west coast of Sumatra. Müller placed the species in the genus Muscicapa and coined the binomial name Muscicapa concreta. The specific epithet concretum is from Modern Latin concretus meaning "large", "sturdy" or "strong". It comes from Medieval Latin concretus meaning "concrete". The white-tailed flycatcher was previously assigned to the genus Cyornis but based on evidence from molecular phylogenetic studies the species is now placed in its own monotypic genus Leucoptilon that was introduced in 2021 by George Sangster and collaborators. The genus name combines the Ancient Greek λευκος/leukos meaning "white" with πτιλον/ptilon meaning "feather".

Possible
About 30% of wildlife watchers report a White-Tailed Blue-Flycatcher sighting in Namdapha National Park on a given day, based on 426 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 33rd most-seen of the 298 birds we can rate there. Over three days the chance rises to about 70%, and over a week to about 90%, if each day is a fresh chance.
January and November
In those months about 40% of wildlife watchers report a White-Tailed Blue-Flycatcher in Namdapha National Park on a given day, against about 10% in April, the lowest month. Those are among Namdapha National Park's driest months, with about 45 mm of rain a month against 660 mm in July. June to September have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most White-Tailed Blue-Flycatcher sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is most active around dawn and dusk.
Yes
Of the 4 parks where we can rate White-Tailed Blue-Flycatcher sightings, Namdapha National Park has the highest daily chance: about 30%. Next come Cuc Phuong National Park (Vietnam, about 10%) and Kerinci Seblat National Park (Indonesia, under 5%).
GBIF citizen-science records
It is estimated from how often the White-Tailed Blue-Flycatcher is recorded against all the birds logged in Namdapha National Park (426 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.
