The long-billed bernieria (Bernieria madagascariensis), formerly known as long-billed greenbul and sometimes as common tetraka or long-billed tetraka, is a songbird species endemic to Madagascar. It is the only species placed in the genus Bernieria. Its natural habitat is subtropical or tropical moist lowland forests.
In 1760 the French zoologist Mathurin Jacques Brisson included a description and an illustration of the long-billed bernieria in the third volume of his Ornithologie based on a specimen collected on the island of Madagascar. He used the French name Le grand figuier de Madagascar and the Latin name Ficedula Madagascariensis Major. Although Brisson coined Latin names, these do not conform to the binomial system and are not recognised by the International Commission on Zoological Nomenclature. When in 1789 the German naturalist Johann Friedrich Gmelin revised and expanded Carl Linnaeus's Systema Naturae he included the long-billed bernieria based on Brisson's description. He placed it with the flycatchers in the genus Muscicapa and coined the binomial name Muscicapa madagascariensis. The long-billed bernieria is now the only species placed in the genus Bernieria...

Very likely
About 70% of wildlife watchers report a Long-billed Bernieria sighting in Ankarafantsika National Park on a given day, based on 371 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 8th most-seen of the 83 birds we can rate there. Over three days the chance rises to over 90%, if each day is a fresh chance.
April, July and October
In those months about 80% of wildlife watchers report a Long-billed Bernieria in Ankarafantsika National Park on a given day, against about 50% in June, the lowest month. Those are among Ankarafantsika National Park's driest months, with about 30 mm of rain a month against 560 mm in January. January–March and May have too few records to rate.
Between 7 and 10 am
Across all the parks we cover, that three-hour window holds the most Long-billed Bernieria sightings with a recorded time, and about 7 in 10 of them come between 6 am and 6 pm: it is a daytime animal.
Yes
Of the 3 parks where we can rate Long-billed Bernieria sightings, Ankarafantsika National Park has the highest daily chance: about 70%. Next come Ranomafana National Park (Madagascar, about 40%) and Mantadia National Park (Madagascar, about 30%).
Same order: Passeriformes
The closest relatives of the Long-billed Bernieria that you can see in Ankarafantsika National Park (order Passeriformes, Perching Birds) are Crested Drongo (about 90%), Madagascar Paradise-Flycatcher (about 90%) and Madagascar Bulbul (about 90%), with each one's daily chance of a sighting.
GBIF citizen-science records
It is estimated from how often the Long-billed Bernieria is recorded against all the birds logged in Ankarafantsika National Park (371 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.
