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.
