Assessment Information [top]

Red List Category & Criteria: Data Deficient ver 3.1
Year Published: 2012
Date Assessed: 2012-05-01
Assessor(s): BirdLife International
Reviewer(s): Butchart, S. & Symes, A.
Facilitator/Compiler(s): Mahood, S., Taylor, J.
This recently split species is classified as Data Deficient owing to uncertainties regarding its tolerance of degraded forest. There are very few records of this species, and research into its ecological requirements and status is urgently required.

Geographic Range [top]

Range Description: Micromacronus sordidus is endemic to the island of Mindanao, the Philippines. It was previously considered conspecific with the Visayan Miniature-babbler M. leytensis, and although it slightly better known than that species, there are few recent records. However, it is tiny and unobtrusive and therefore may be more common than currently thought.
