Ludlow Ibis 45-46
Characteristic birds of Chayal Dzong

Corvus corax tibetanus The Tibetan Raven - Ibis 65
Was seen everywhere north of the main range
but was decidedly scarce in the lower reaches of
the Tsangpo below Lilung.
Seen twice south of the main range
(a) at Trimo in the Nyam Jang Chu valley
at the foot of the Poda in April 1936
(b) at Keupup in Sikkim at the foot of the Jelep La in Feb. 1938

Pica pica bottanensis Tibetan Magpie. - Ibis 65

Trochalopteron henrici Prince Henri's Laughing Thrush. Ibis 77

Parus major tibetanus - Tit

Prunella rubeculoides rubeculoides - everywhere on the Tibetan Plateau Ibis 192

Phylloscopus affinis Willow Warbler. Ibis 197-198.
Occurs all down the Tsangpo as far as Gyala in the Gorge, carefully
avoiding forest, keeping to low scrub growing on the sandy banks
of the river.

Propasser pulcherrimus waltoni Rose Finch. Ibis 352.
Abundant in the upper reaches of the Subansiri & all down the Tsangpo
from Tsetang to Gyala in the Gorge north of the main range common
also up the Gyamda Chu. Undoubtedly the commonest Rose Finch in SE Tibet
most plentiful at the lower elevations especially in the semi-dry areas where
the hill-sides are covered with Quercus ilex.

Carpodacus rubicilloides lucifer Ibis 353
Common bird in the arid parts of Tibet, especially where there are buckthorn thickets
Common in the Tsangpo Valley as far as Lhagyari but not noticed east of
this locality, though it doubtless occurs as far as Nang Dzong.

Perdix hodgsoniae hodgsoniae Tibetan Partridge. Ibis 384.
Seen near Tsong & down the Chayal Chu as far as Chayal Dzong.
Occurred on the Cha La & Bimbi La in Tsari & at Shira above Sanga Chöling

SUMMARY:
Notes describe eggs and nesting of Trochalopteron henrici near Migyitun, including egg color, nest placement, and clutch size, with laying in May and early June. A list of plant taxa with specimen numbers (including several Rhododendron and Corydalis) is recorded.

CONTENT:
L. 100 Set eggs c/3 of Trochalopteron henrici (Prince Henri's Laughing Thrush).
Pale greenish. They are exactly like those of the common Song Thrush at home.
L. Dis 77. I do not think it occurs south of the main range except at Migyitun.
We found numerous nests, they are generally placed in bushes, seldom at no
great distance from the ground. They are rather untidy structures of dried
grass, dead leaves, strips of birch bark, moss etc. lined with dry twisted
grass. Clutches vary from 2-3. Eggs laid in May & early June.

SUMMARY:
After a very cold night with snowfall, the party enjoyed clear weather and fine scenery with Sengdam La visible, noted a large flock of Grandala at Tumbabe, and observed various birds including geese and mallard (two of which were shot and retrieved). They marched from Lunang to Daú below Chunjima, remarked on Lunang ironwork, and collected plants including Notholirion hyacinthinum, a Codonopsis (seed), and a probable Primula sonchifolia.

Last night was very cold indeed, and 1/2" snow fell. The fall was general down to well below this place. It was rather sickening to wake up to a perfect clear morning, which if we had had yesterday would have given us wonderful views. Today the scenery was very fine, even without any sight of Gyala Peri or Namcha. Sengdam La, 20,700', is visible for a good part of the day, in a fine background to the open grassy valley & Picea-clad hills on either side. Again at Tumbabe, we found a huge flock of perhaps 300 Grandala, feeding on Hippophae. I took both cine & still photos of these. Birds were very numerous again, all of a sudden. Trochalopteron henrici & affinis & Ianthocincla ocellata, besides rose finches & accentors. We saw no game birds but 2 geese, which certainly were not bar-headed or grey lag. I think they must have been white fronted. I could easily have shot both, but had just sent off Tsongpen with the gun. In Lunang they make pierced iron work — waist belt ornaments, swords cases & so on. We have seen the waist belt pieces — six, each about 3" long. Total price asked 20 sangs, which would normally equal about Rs 3/-.

21st Dec. Daú. (about 2-3 m. below Chunjima). Last night the cold was intense, due to snow & a very clear sky. There is little doubt that this side of the Temu La is much colder than in the Tsangpo valley at similar heights. It was a difficult job rolling up the tent, but we were off at 7.50 again, arrived here about 2.0. This was a short march, but a very pleasant one indeed. At first the temp was so low that we couldn't get warm, but by 9.30 we were in the sun & comfortable. About a mile from Lunang, I saw four mallard on the river, & shot two. Both fell in the half frozen river, but were rescued. Otherwise there were few birds seen today anything of interest. Of plants we saw more. Notholirion hyacinthinum was again seen & seed of a Codonopsis was taken.
R. Hunter 12021 The most interesting find however, was what I took to be Primula sonchifolia. It was growing on a slope which got no sun, & so the ground was frozen very
