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 SITTIDÆ OR NUTHATCH FAMILY
32. Sitta himalayensis. Very abundant in the neighbourhood of Darjeeling.
THE DICRURIDÆ OR DRONGO FAMILY
33. Dicrurus longicaudatus. The Indian Ashy Drongo.
THE CERTHIIDÆ 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.
