Tessmann's flycatcher (Fraseria tessmanni) is a species of bird in the family Muscicapidae. It is sparsely distributed across the African tropical rainforest from Sierra Leone to the Democratic Republic of the Congo. Its natural habitat is subtropical or tropical moist shrubland.
Tessmann's flycatcher was formally described in 1907 by the German ornithologist Anton Reichenow under given the binomial name Psalidoprocne tessmanni. The specific epithet was chosen to honour the German anthropologist and collector Günter Tessmann (1889–1971). Tessmann's flycatcher is now one of eight species placed in the genus Fraseria that was introduced in 1854 by the French naturalist Charles Lucien Bonaparte. The species is monotypic: no subspecies are recognised.

Rare
Under 5% of wildlife watchers report a Tessmann's Flycatcher sighting in Kakum National Park on a given day, based on 7 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 242nd most-seen of the 250 birds we can rate there. Over three days the chance rises to under 5%, and over a week to about 10%, if each day is a fresh chance.
September
In that month about 10% of wildlife watchers report a Tessmann's Flycatcher in Kakum National Park on a given day, against under 5% in October to August, the lowest months. That is one of Kakum National Park's wettest months, with about 210 mm of rain against 35 mm in January.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Tessmann's Flycatcher 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 Kakum National Park, in our data
Kakum National Park is the only park on Wallace's Line with enough records to rate Tessmann's Flycatcher sightings: under 5% of wildlife watchers there report one on a given day.
GBIF citizen-science records
It is estimated from how often the Tessmann's Flycatcher is recorded against all the birds logged in Kakum National Park (7 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.
