Andaman Treepie Dendrocitta bayleyi

Justification
This species has a small range, and may be suffering moderate declines as a result of habitat loss, although its habitat and population are not regarded as severely fragmented or restricted to a few locations. 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
Dendrocitta bayleyi is endemic to the Andaman archipelago, India (BirdLife International 2001). It is uncommon to locally fairly common and while habitat on the Andamans remains relatively intact it is probably secure.

Population justification
The population size of this species has not been quantified; it is considered common.

Trend justification
Data are lacking on population trends, but slow declines are suspected to be occurring, owing to increasing human population pressure within the species's range.

Ecology
This species is usually found in pairs or parties of up to 20 birds, or in mixed flocks in tall trees in dense broadleaved evergreen forest.

Threats
Human population pressure and rates of habitat loss may be increasing in the Andaman archipelago, suggesting that natural habitats within the small range of this species might rapidly shrink and become fragmented.

Conservation Actions Underway
No targeted conservation actions are known for this species, although some of its habitat is protected.

Conservation Actions Proposed
Monitor populations across the species's range, as well as trends in human activities and habitat loss. Conduct ecological studies to determine levels of tolerance of secondary, disturbed or fragmented habitats. Protect areas of suitable habitat and safeguard against potentially increasing threats.
