Helmeted Myna Basilornis galeatus

Justification
This species has a highly restricted and fragmented range, and it is likely to have a moderately small global population size. Declines are suspected to be occuring owing to habitat loss, although montane populations (and those in secondary habitats) are likely to be relatively secure. It is therefore considered Near Threatened.

Taxonomic source(s)
Sibley, C. G.; Monroe, B. L. 1990. Distribution and taxonomy of birds of the world. Yale University Press, New Haven, USA.

Distribution and population
Basilornis galeatus is restricted to the Banggai (Peleng, Banggai) and Sula Islands (Taliabu, Seho and Mangole), Indonesia.

Population justification
The population size of this species has not been quantified, but it is described as scarce to locally common.

Trend justification
Whilst this species does persist in secondary habitats in some areas, it apparently prefers pristine forests, and is therefore suspected to be declining slowly as a result of habitat loss.

Ecology
This species inhabits lowland and montane forest and tall trees in reedswamps up to 1,000 m. In the Banggai Islands, at least, it can be found in secondary forests.

Threats
This species may be relatively secure in montane regions as a result of the inaccessibility of its habitats to humans. However, in the Sula lowlands it is becoming uncommon and is increasingly vulnerable to the loss of the least disturbed forest, its preferred habitat.

Conservation Actions Underway


Conservation Actions Proposed
Conduct repeated surveys within the range to determine current distribution and abundance, as well as assess population trends and rates of habitat loss. Conduct ecological studies to improve understanding of its precise habitat requirements, particularly tolerance of secondary habitats and response to fragmentation. Protect areas of suitable habitat, particularly in the Sula lowlands, and protect against disturbance and other threats.
