Yellow-rumped Honeyguide Indicator xanthonotus

Justification
This scarce and poorly known species is thought to have a moderately small global population size as a result of its narrow habitat requirements and strong association with giant honey bee Apis dorsata colonies. It is likely to be declining as a result of habitat loss and honey extraction by humans, and is therefore considered Near Threatened.

Taxonomic source(s)
del Hoyo, J.; Collar, N. J.; Christie, D. A.; Elliott, A.; Fishpool, L. D. C. 2014. HBW and BirdLife International Illustrated Checklist of the Birds of the World. Barcelona, Spain and Cambridge UK: Lynx Edicions and BirdLife International.

Distribution and population
Indicator xanthonotus occurs in Pakistan (possibly a seasonal or nomadic visitor; there are no recent records), Nepal (local and uncommon), India (very rare and local), Bhutan (local and uncommon), China (rare in south-east Tibet) and Myanmar (rare resident in the north) (BirdLife International 2001). It is generally assumed to be a rare species, although easily overlooked due to its inconspicuous behaviour and it may be more common than the paucity of records suggest.

Population justification
The population size of this species has not been quantified; it is considered very rare to uncommon throughout its range.

Trend justification
Little is known of the population trends of this scarce species, but slow declines are suspected to be occurring as a result of the human exploitation of giant honey bee colonies, as well as habitat loss and degradation within the range.

Ecology
This species occurs in rocky gorges and valleys with broadleaved or coniferous forest, usually between 1,450 and 3,500 m. Males defend giant honey bee Apis dorsata nests that are usually attached to vertical cliffs. It may be an obligate brood parasite, although hosts are unknown.

Threats
It has been suggested that over-exploitation of bees' nests for honey by human populations in the Himalayas might have a deleterious impact on its populations. Similarly, the loss of floral diversity as a result of agricultural expansion could affect bee populations. Forest loss could also influence this species.

Conservation Actions Underway
No targeted conservation actions are known for this species.

Conservation Actions Proposed

Conduct repeated surveys across the species's range to determine the magnitude of declines and rates of range contraction. Conduct ecological studies to determine precise habitat requirements and breeding biology, as well as tolerance of secondary habitats and response to fragmentation. Campaign for the protection of giant honey bee colonies, as well as flower-rich habitats within the species's range.
