Yellow rumped honey guide, Bhutan 

The yellow rumped honeyguide is a sparrow-sized bird in the honeyguide family that is found in Asia, mainly in montane forests along the Himalayas. They are very finch-like but the feet are strong and zygodactyl, with two toes facing forward and two backward. They perch on honeycombs and feed on wax. Males tend to be territorial and stay near honeycombs while females and juveniles forage widely. They are brood-parasites, laying their eggs in the nests of tree-hole breeders, possibly barbets. They are classified as near threatened by IUCN.
