SUMMARY:
After the flowering season, the party spent three months collecting birds and seeds, moving slowly through the Trashiyangsi valley, revisiting Sakden, and exiting via Dewangiri on 15 Nov. Around 750 skins were obtained, with emphasis on Troglodytidae and other notable species, including range extensions from the East Bhutan frontier and large flocks of grosbeaks at Dewangiri. Notes include a reference to a description of the Yongbon Chu valley and remarks on the Dongkar–Cho La–Me La route used by Bhutanese coolies from the Tawang area.

We moved very slowly, making prolonged halts at various places in the Trashiyangsi valley and again visited Sakden. We finally made our exit via Dewangiri on 15 Nov.

Nearly 750 skins were obtained during these last 3 months. We paid particular attention to the Troglodytidae and secured large and carefully sexed series of

p 104. The Dongkar, Cho La, Me La route is well frequented and many Bhutanese coolies use it on their way from Tawang area to Dongkar. It is fit for pack transport although in places the track is a bad one.
