The brown-streaked flycatcher (Muscicapa williamsoni) is a species of bird in the family Muscicapidae. It is found in southern Myanmar, southern Thailand, northern peninsular Malaysia, and northeast Borneo. Some authorities consider it to be a subspecies of the Asian brown flycatcher. In 2020, a vagrant was sighted 300 km (190 mi) south of the Australian town of Broome and its identity was confirmed from DNA analysis of the droppings of the bird.
The species has a rufescent plumage in the breeding season and then becomes drab. The species name is after the collector Sir Walter James Franklin Williamson. Wikipedia →

Rare
Under 5% of wildlife watchers report a Brown-streaked Flycatcher sighting in Sepilok on a given day, based on 103 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 139th most-seen of the 242 birds we can rate there. Over three days the chance rises to about 10%, and over a week to about 20%, if each day is a fresh chance.
February, July and October
In those months about 10% of wildlife watchers report a Brown-streaked Flycatcher in Sepilok on a given day, against under 5% in March–June, August–September and November–January, the lowest months.
Between 9 am and noon
Across all the parks we cover, that three-hour window holds the most Brown-streaked Flycatcher sightings with a recorded time, and about 9 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
2nd of 3
Of the 3 parks where we can rate Brown-streaked Flycatcher sightings, Sepilok ranks 2nd at under 5%. The best odds are in Khao Luang National Park (Thailand, about 10%).
GBIF citizen-science records
It is estimated from how often the Brown-streaked Flycatcher is recorded against all the birds logged in Sepilok (103 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.
