Long-billed Bernieria

Bernieria madagascariensis

Least Concern

The species is abundant and widely distributed; it faces no significant short-term risk.

Spotted something wrong?

It belongs to the Bernieridae, a family endemic to Madagascar whose existence was only firmly established in the twenty-first century: for decades its members had been scattered among the bulbuls, the warblers and other families on the strength of superficial resemblance.

Fun facts

  • Its family is a recent discovery: well into the twenty-first century its species were still scattered among the bulbuls, warblers and other families, and only genetics revealed that they form a group of their own, confined to Madagascar and descended from a single colonisation.
  • It is an example of island adaptive radiation: from a common ancestor, the species of that family today occupy niches as different as the understorey, the canopy and the tree trunks, with very different bills.
  • It is a regular member of the mixed flocks of the Malagasy forest, in which several species travel together and benefit from the collective watch.
