Description
The yellow-rumped honeyguide is sparrow sized and has a stout finch-like bill. The plumage is largely dusky olive and the forehead and lores are orange while the upper plumage. There is a streaked appearance to the wing feathers. The rump is deep orange and extends into the back grading to sulphur yellow. The chin and throat are yellowish while the lower plumage is pale grey with dark streaks. The bill is yellow but dark towards the tip. Females have less extensive yellow on the face and the rump is yellow and lacks the orange. Allan Octavian Hume described the subspecies radcliffi (after Colonel E. Delmé-Radcliffe) based on specimens from Hazara but no specimens or information from the region have subsequently been obtained putting it in some doubt. The species was described by Blyth based on specimens from near Darjeeling. Ripley described specimens from the Naga Hills as subspecies fulvus (not always recognized), said to be smaller and darker, with the streaking on the abdomen reduced and the yellow on the forehead restricted to the anterior. This population may be identical to the nominate of the eastern Himalayas. They have twelve tail feathers and nine primaries. The wing is long and pointed.

Feeding Habits
Yellow-rumped Honeyguide primarily consumes beeswax, particularly from Apis dorsata nests, and catches various insects mid-flight. Yellow-rumped Honeyguide frequents rock-face bee nests for unguarded wax and is known to gather in groups after breeding to exploit wax resources, with males defending territories year-round.
Habitat
The habitat of yellow-rumped Honeyguide predominantly comprises rocky wooded gorges and streamside cliffs, often in proximity to giant honeybee colonies. These birds are typically associated with regions where mixed decidouns-coniferous or dry deciduous forest is present, reflecting a preference for diverse woodland environments.
Dite type
Insectivorous

Behavior
A chipping call is produced in flight and when agitated. The flight is straight (may sometimes be undulating) and direct, sometimes in flocks of 20 to 30 birds. At deserted honeycombs, the bird clings tight and presses its tail on the surface of the comb. They feed mainly on the foundation wax of Apis laboriosa that attach the comb to rocks. They feed on active beehives without disturbing the bees much. They have been observed to make use of the attacks of Vespa mandarinia on Apis laboriosa colonies. A display of a male involved fluffing its feathers, holding the bill high and flicking wings while swaying from side to side. A female was observed flicking its tail and pressing it down with wings drooped before being mounted by a male. They are brood parasites, laying their eggs in the nest of host species. The host species for the yellow-rumped honeyguide are as yet unknown and undocumented. Young birds of honeyguide species have bill-hooks with which they destroy the eggs and chicks of the host. The male holds territories around hives and are polygynous, allowing females with whom it had mated and their young into the territories. This mating system has been termed as "resource-based non-harem polygyny". Unlike other honeyguides, this species has not been observed to lead humans and bears to bee hives.
Distribution Area
The species has been recorded from northern Pakistan (Hazara and Murree Hills) but the population here may have been extirpated and then in the Himalayan regions of India from western Uttar Pradesh and Himachal Pradesh extending into Nepal, Sikkim, Arunachal Pradesh and Bhutan (where it is relatively common). It is also found in southeastern Tibet and northern Myanmar. It is found in coniferous and dry-deciduous forest with rocky boulders and cliffs. May make altitudinal movements seasonally.
