NT
Pied Cuckooshrike Coracina bicolor



Justification

Justification of Red List Category
This species is likely to be in moderately rapid decline owing to continued habitat loss and degradation, and is therefore considered Near Threatened. It should be monitored carefully for future increases in the rate of decline.

Population justification
The global population size has not been quantified, but the species is described as genreally uncommon to rare on Sulawesi, common in northern Sulawesi and uncommon on Buton (del Hoyo et al. 2005).

Trend justification
Population declines are suspected to have occurred as a result of deforestation and habitat degradation within the species's range.

Distribution and population

Coracina bicolor is restricted to Sulawesi, the Togian Islands, Muna, Buton and the Sangihe and Talaud islands, Indonesia (BirdLife International 2001). It is generally uncommon, with a fragmented distribution, being apparently absent from many areas within this range, e.g. central and eastern Sulawesi. It is uncommon on Buton, and there are only two records from Sangihe (del Hoyo et al. 2005).

Ecology

This species inhabits lowland primary forest and hill forest with clearings up to 900 m (fairly common on Buton at 500-700 m [T. Martin in litt. 2016]), although in many places it is only found much lower. It is also recorded from scrub and mangroves.

Threats

Forest destruction within its elevation range has been extensive in recent decades, and its populations must have suffered a commensurate decline.

Conservation actions

Conservation Actions Underway
No targeted conservation actions are known for this species, although it occurs in a number of protected areas.

Conservation Actions Proposed
Conduct repeated surveys in areas within and surrounding the species's range to determine current distribution and abundance, as well as assess population trends. Conduct ecological studies to improve understanding of its precise habitat requirements, tolerance of secondary habitats and response to fragmentation. Protect areas of suitable habitat.
