Tits are small birds, smaller than sparrows, which usually go about in flocks. They spend most of their lives in trees. In seeking for insects, on which they feed largely, they often hang upside down from a branch. All tits have these habits; but all birds of these habits are not tits. Thus the following of the babblers described above have all the habits of tits: the white-eye, the black-throated babbler, the red-headed babbler, the blue-winged siva, the yellow-naped ixulus, the striped-throated yuhina, and the red-tailed minla. The above are all birds of distinctive colouring and may be easily distinguished. Other small birds which are neither tits nor babblers go about in flocks, as, for example, nuthatches, but these other birds differ in shape and habits from babblers and tits, so that no one is likely to confound them with the smaller Corvidae or Crateropodidae. 29. _Molpastes leucogenys_. The white-cheeked bulbul. Common below elevations of 5000 feet. 30. _Hypsipetes psaroides_. The Himalayan black bulbul. Not very common. 31. _Alcurus striatus_. The striated green bulbul. Upper plumage olive-green with yellow streaks. Cheeks dark brown, streaked with pale yellow. Chin and throat yellow, with dark spots on throat. Patch under tail bright yellow. Striated green bulbuls go about in flocks which keep to the tops of trees. They utter a mellow warbling note. They are abundant about Darjeeling. THE SITTIDAE OR NUTHATCH FAMILY 32. _Sitta himalayensis_. Very abundant in the neighbourhood of Darjeeling. THE DICRURIDAE OR DRONGO FAMILY 33. _Dicrurus longicaudatus_. The Indian Ashy Drongo. THE CERTHIIDAE OR WREN FAMILY 34. _Certhia discolor_. The Sikhim tree-creeper. This species displaces the Himalayan tree-creeper in the Eastern Himalayas. The two species are similar in appearance. 35. _Pneopyga squamata_. The scaly-breasted wren. In shape and size this is very like the wren of England, but its upper plumage is not barred with black, as in the English species. It is fairly common about Darjeeling, but is of retiring habits. THE SYLVIIDAE OR WARBLER FAMILY 36. _Abrornis superciliaris_. The yellow-bellied flycatcher-warbler. A tiny bird about the size of a wren. The head is grey and the remainder of the upper plumage brownish yellow. The eyebrow is white, as are the chin, throat, and upper breast: the remainder of the lower plumage is bright yellow. 37. _Suya atrigularis_. The black-throated hill-warbler. The upper plumage is olive brown, darkest on the head. The chin, throat, breast, and upper abdomen are black. THE LANIIDAE OR SHRIKE FAMILY 38. _Lanius tephronotus_. The grey-backed shrike. 39. _Pericrocotus brevirostris_. The short-billed minivet. Very common about Darjeeling. 40. _Campophaga melanoschista_. The dark-grey cuckoo-shrike. Plumage is dark grey, wings black, tail black tipped with white. Rather larger than a bulbul. Cuckoo-shrikes keep to trees, and rarely, if ever, descend to the ground.
