Red List Category & Criteria:

Near Threatened ver 3.1

Year Published:

Assessor/s:

BirdLife International

Reviewer/s:

Taylor, J., Butchart, S.

Contributor/s:

Justification:
This species is listed as Near Threatened because it may suffer a moderately rapid population decline during the next ten years, owing to habitat loss for subsistence agriculture combined with a potential increase in hunting pressure. If the rate of any future decline is found to be greater, the species may qualify for uplisting to a higher threat category.

History:

2004	–	Near Threatened
1996	–	Vulnerable
1994	–	Vulnerable

Geographic Range [top]

Range Description:	Atelornis crossleyi is found in the more humid highland areas of the evergreen forest belt of eastern Madagascar⁴, from Tsaratanana south to Andohahela. Recent work has found that this species has a larger population and wider distribution than previously thought^2,3.

Habitat and Ecology [top]

Habitat and Ecology:	It inhabits humid parts of lowland to high-altitude rainforest, occurring from sea-level to 2,000 m, and is at its most common between 1,250 and 1,750 m⁵. It is predominantly a terrestrial feeder, taking a variety of invertebrates. Breeding may take place in December-January. The nest burrow is 0.3-0.5 m long and is excavated in a sloping earth bank. Its clutch-size has been recorded as two⁵.
Systems:	Terrestrial

Threats [top]

Major Threat(s):	The species's habitat is threatened by slash-and-burn cultivation^1,5, although it is not as affected as species that are restricted to lowland forests, which are under the greatest threat⁵. Increased hunting could seriously impact this species.

Conservation Actions [top]

Conservation Actions:	Conservation Actions Underway It occurs in at least 12 protected areas⁵. Conservation Actions Proposed Conduct surveys to obtain data on density and thus a total population estimate. Monitor rates of habitat clearance and degradation across its range. Increase the area of suitable habitat that is protected.
