Yellow-rumped Honeyguide

The yellow-rumped honeyguide is a sparrow-sized bird with a stout, finch-like bill, found in Asia mainly in montane forests along the Himalayas. The plumage is largely dusky olive with an orange forehead and lores, and the rump is deep orange, extending into the back and grading to sulphur-yellow. The feet are strong and zygodactyl (Wikipedia, general species account).

Birds perch on honeycombs and feed on wax, mainly the foundation wax with which the giant honeybee attaches its combs to rocks. Males tend to be territorial and stay near honeycombs while females and juveniles forage widely. It is a brood parasite, laying its eggs in the nests of tree-hole breeders, possibly barbets. A chipping call is given in flight and when agitated (Wikipedia, general species account).
