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...

With luck
About 10% of wildlife watchers report a Long-billed Bernieria sighting in Montagne d'Ambre National Park on a given day, based on 6 verified sightings from GBIF citizen-science data from 2019 to 2026. It is the 27th most-seen of the 30 birds we can rate there. Over three days the chance rises to about 30%, and over a week to about 60%, if each day is a fresh chance.
Between 8 and 11 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.
5th of 5
Of the 5 parks where we can rate Long-billed Bernieria sightings, Montagne d'Ambre National Park ranks 5th at about 10%. The best odds are in Ankarafantsika National Park (Madagascar, about 70%), Ranomafana National Park (Madagascar, about 40%) and Mantadia National Park (Madagascar, about 30%). All parks ranked.
GBIF citizen-science records
It is estimated from how often the Long-billed Bernieria is recorded against all the birds logged in Montagne d'Ambre National Park (6 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.
