A PRELIMINARY LIST OF THE BIRDS OF KHAO YAI NATIONAL PARK

By E.C. DICKl NSON, M.B.O.U. INTRODUCTION.

This preliminary list of the Birds of Khao Yai National park is primarily based on personal observations by P.F. Cumberlege and the author. However, much valuable comparative material has been drawn from J.H. Riley's excellent treatise on the collections of Dr. H. M. Smith who collected, amongst other places, extensively around Pak Chong (which lies north of our boundary ). I have refrained from including all the Pak Chong collected species, for this article would then be less restricted to the actual park of Khao Yai than is desirable. However, three of the localities at which Smith collected are within, or very close to, the park and birds taken there I have covered (those however which neither P.F.C. nor I have observed are only listed in Appendix I). The three localities are:Trrha Chpanhg } just outside our area to the north of Khao La em. ,_nong ra Kao Lem = Khao Laem. (The last named place has suffered some confusion in Riley's work with Kao Lem Sing, near Chantaburi in S.E. Thailand but only, I think, on Malacocincla abbotti and Cyanops incognita ). NOMENCLATURE/ REFERENCES.

I have used the nomenclature used by H.G. Deigtum in "The Birds of Northern Thailand" and his order, since this work is the most useful local work. I have also given references to it for it contains excellent descriptions for all except a very few of the species annotated here. (" D " indicates this work). Riley'"<: nomenclature varies from that adopted by Deignan in some cases but a synonymy is not necessary. "The Birds of Burma" by B.E. Smythies contains illustrations of many of the species listed and the plate

numbers are given where app ropriate (this work being readily obtainable) . To this work too I refer on 2 of the species not covered by Deig 11an's work, and fo r N ightjar calls. (" S" indicates this work) . Parentheses, [ ], around English names indicate that the species is listed with reservations, further observations are needed to confirm the tentative identification. I have not used trinomials, for sub-specific field id entifications are rarely feasible or wise. I have not felt it necessary for a work of this t ype to include the name of the original describer of the species. For English names I have taken the most appropriate from the above works and even very slightly changed some. LOCATION, GEOGRAJ'HY & HABITATS.

The accompanying article by P.F. and V.M.S. C umberlege on Orchids deals very adequatel y with the general details. Khao Yai lies in the Sankambeng range which runs from S.E. to N.W., nothing in its location makes it apparently important to migration or speciation, except that the bulk of the massif and the heights of the taller peaks give refuge to several forms one might not expect this far South - one such is Enicurus schistacaeus. The habitats need perhaps further description in relation to the birds, and the separation is not quite as for orchids.

1. Lower deciduous forest- to be found along Thanarat road and to the edge of the foothills. Typical birds of the area Psittawla alex andr i, Acridother es f uscus and Coracias benghalensis. 2. Bamboo brakes - together with dry evergreen - replace it on the slopes. Not much explored for birds. 3. Dry evergreen, with strong undergrowth, and in cleared areas a growth of wild bananas, runs up the slopes to the plateau. Birds are very few. 4.

Hill evergreen - which can be split further into : Upper

-

with conifers Podocarpus and Dacridium heavily invested with lianas, moss, lichens, etc. 1100 m. up.

Middle

evergreen chestnuts and oaks, Quercus, LithocarptLS and Castanopsis 1000 m. - 1100 m.

Lower

mainly dipterocarps with varying degrees of undergrowth and fern etc, 750 m. - 1000 m.

Needless to say this is rather arbitrary and much overlapping takes place. I do not think one can justly split the Middle and Lower evergreentogether they form a wonderfully rich bird habitat. The upper does have some other typical forms. e.g. A ethy opaga saturata. 5. Old clearings-lalang covered. T ypical birds are Centropus beng alensis, Prinia rztfescens, Cisti cola ex ilis and Py cnonotzts j ocosus. DATES & COVERA GE.

Oriental Darter.

Anhin g a rufa

(D. 31, S. XXVII).

Seen once on the lake in the camp area by P.F.C. , and seen Aying over going S.W . on 12.4.63 .

k.C. DicKINSON

Green Heron.

Butorides striatus

(D. 33, S. XXVIII). Probably seen by P.F.C. in January 1963, and then definitely recorded on 8.2.63 and 16.3.63 at different points along the Lam Ta Krong (about 700- 850 m.)

Pond Heron.

Ardeola bacchus

(D. 35, S. XXVIII). This species is apparently present during the dry season at the small lakes in the valleys of the massif. These birds assume summer plumage before leaving about June- presumably to the plains to breed. The identification of the three races of Pond Heron is difficult even in summer plumage- and I find little agreement even there between the sources I have been able to consult.

Blyth's Baza.

Ba za jerdoni

There is a crepuscular bird of prey that appears over the lalang clearings at dusk in some numbers and calls plaintively. Limited views have allowed sight of a crest. Only 2 species are possible and both should show white on the underside of their plumage; one of them is this species, the other is the Bat Hawk Machaerhamptts alcirws. However, no white has been seen on the Khao Yai bird. I am of the opinion that the birds are Ba::a jerdoni. P.F.C. is undecided. I base my decision of the following points:1. B . jerdoni is reportedly gregarious- up to 14 individuals have been seen together at Khao Yai. 2. M . alcinus is not believed to have occurred north of Tennasserim and Peninsular Thailand- it is also reputedly associated with limestone outcrops which are lacking at Khao Yai. 3. B . jerdoni has been taken by Smit!t near Pak Chong 17.11 .25 (see Riley p. 43 ). 4. A specimen of B. jerdoni- the only one examined - in the collection of Dr. Boonsong Lekagul shows so little white that viewed from beneath at dusk it could well be impossible to see. For a description see Stuart Baker's Fauna of British India, Birds, Vol. V p. 174.

Honey Buzzard.

KHAO YAi NATIONAL PARK

u37

Pernis ptilorhyncus

(D. 59). Seen just outside the park along Thana rat Road 10.2.63. Also taken at Tha Chang by Smith 15.3.27. This bird must certainly occur within the park.

[ Horsfield's Sparrowhawk]

Accipiter soloensis

(D. 65 ). One near the South end of the ridge on Khao Khieow 9.2.63. , but the species is too difficult to identify in the fi eld for certain from a view of so short a duration.

Rufous-Winged Buzzard Eagle.

Butastur liventer (D 69, S. XX). 1 adult and and an immature bird seen ci rcling ove r 1·he pflrk 11 .8.63.

Black Eagle (D. 72) .

I ctina·etus malayensis

First seen in January from above by P.F.C. when on Khao Khieow. Two seen flying, well separated, towards there on 9.2.63, one wfls seen by P.F.C. at Heo Suvvat waterfall on 21.7.63, and one or two on Khao Khieow 11.8.63.

[Harrier sp? ].

Circus sp ?

One bird, probably a Pied Harrier C. melanoleucos, was seen fl ying over the park during March 1963, and another juvenile was seen near the bungalows by P.F.C. one evening in May 1963.

Crested Serpent Eagle.

Spilornis cheela

(D 78, S. XIX). One seen 3.3.63, a pair circling and calling 17.3.63, and one 12.4.63. The pa le sub-terminal bar on the wings and tail- very clear when looking at a soaring bird from below- is a good field mark.

[Falcon sp?] Falco sp ? A small and rather undistinguished falcon is regularly seen about the camp area. It has not yet been seen really well, but although the bird has never been seen hovering it is most likely to prov e F ulco tinnunculus .

E.C. DICKINSON Microhie ra x caerulescens

This delightful littl e bird has been sPen just outside the park boundary along Thanarat Road. 3 on 4.5.63, with 6 there the follow ing day for a moment they were all perched in a group. 2 on 9.7.63, one of them. in the same vicinity. It almost certainly will be found within the park boundary.

Silver Pheasant. (D. 94 ).

Gennaeu.s ny cthemuru.s

This species has been seen by P.F.C . dawn or dusk.

Junglefowl. (D. 96, S. XXII).

It should be looked for at

Gallu s p:allns

This bird is certainly present in the park 111 good numbers and may be heard crowing by almost any visitor. It comes into the open in early morning and evening and has been seen on numerous occas10ns. P.F.C. found a nest and eggs in May 1962. Smith took a male at Tha Chang 1.1.31.

[ Hemipode sp ?.]. (D. 100).

'l'urni x sp

::J

It seems probable that T. tanki occurs here at least in winter for the bird seen on 3.3.63 had yellow feet, others seen 12.4. and 7.3.63 were not seen so clearly and may well be T. suscitator which could be expected as a resident in the lalang covered clearings.

Little Ringed Plover. (D. 119, S. XXV).

Charadrius dubius

One has been seen by P.F.C. on the edge of the lake about December 1962., another by the author 10.8.63 on a laterite road by the camp.

Pink-Breasted Paral•eet. (D. 135, S. XVI).

Psittatula ale xa.ndr i

This bird occurs in the deciduous forest along Thanarat Road close to, and almost certainly within, the park- parakeets have been seen flying over ~n small flocks on several occasions.

A PRELIMINARY LIST Of TUE BIRDS OF KHAO YAl NATIO'IAL PAHK

Lorikeet.

189

Loriculus verna./is

(D. 139, S. XVI). One seen briefly 10.2.63 perched on a tall bare tree standing above the main canopy at a spot about 800 m. above sea level, and a flock of about 25 at the edge of the massif by the 'Viewpoint' on 12.8.63.

Smaller Thick-Billed Green Pigeon.

Treron wrvirostra

(D. 143, S. XXI). Several lone green pigeons seen briefly have been thought to be this but confirmation was not had until 16.3.63., however on 4.5.63 good views were had of a flock of about 15. 'l'he casual observer should not assume all green pigeons to be of this race- T. potnpa.clora is probably present and others of this large group may well occur.

l\'lountain Imperial Pigeon. (D. 149 ).

Ducula badia

'This large pigeon has been seen on several occasions usually flyin g high over the camp area. It has been seen perched nearby on 16.3.63 and 14.4.63.

Barred Cuclwo Dove.

Macropygia un chall (D. 150). 'This long tailed brown dove is a common resident but hard to get close to. Good views were not obtained until 10.8.63.

[Rufous Dove]. (D. 152, S. XXI).

Streptopelia orientalis

A shy dove that has been flushed from the cleared ground near the bungalows at the camp is thought to be of this species.

Spotted-Necked Dove.

Streptopelia chinensis (D. 153, S. XXI). On 6.7.63 the hill road up onto the massif was swarming with these birds- not long after rain, which were also seen in August. Smitlz took a male at 'Tha Chang 23.11.25.

Emerald Dove.

Clwlcophaps indiciL (D. 156, S. XXI). A bird of the hill evergreen emerging to drink at pools by the roadsides- particularly in the early morning. Seen quite often. ·

190

E.C. DICKINSO N

Large Green-Billed Malkoha. Rhopodytes trisl,is (D. 168, S. XV). Seen 3.3.63, 8.7.63, 10.8.63 and 11.8.63., this is a species which skulks, and is usually only seen as it slips quietly from one thick tree to another.

Greater Coucal. (D. 169, S. XV).

Centropus sin ensis

This bird has been seen towards evening along Thanarat road right up to the sign over the road at the park entrance. It has not been seen higher up.

Lesser Coucal. (D. 170).

Centropus benghalensis

Deignan remarks that this bird can be found in hill stands of lalang and at Khao Yai it has been found up on the main massif where the lalang clearings have weed grown valleys. These birds have all appeared in the dress that Deig11a11 describes as immature, and have been seen in February and March.

Collared Scops Owl. Otus usio (D.175). Heard calling 8.2.63 near the camp area. Long-Tailed Nightjar. Caprinwlgus macruru,s (D.185, S. page 370). There are nightjars regularly around the camp area at Khao Yai and on Forestry Hill. In May 1962 P.F.C. found and photographed one young but unidentifiable chick about a week old. These birds however are notoriously difficult to identify and in spite of good views of birds in the headlights perched at only 10 yards range, I am relying on the 'Summary of Nightjar Calls' published on p. 370 in Smythies to identify these birds.

[Swifts?].

Clwetura/Apus

Swifts can be regularly seen over the area- particularly above Heo Suwat Waterfall- two types prevail: a large swift with very pale under-tail coverts, probably C. gigantea- which was collected at Tha Chang by Smith

oh 16.3.27, and a smaller, slower-flying white-rumped individual probably A . affinis or A. pacificus.

Palm Swift. (D. 191, S. XVIII).

Cypsiu.t'ns pahms

A very few have been seen occasionally over the park- they he stragglers from the lower slopes where suitable palmso ccur.

Red-Headed Trogon. (D. 193, S. XVIII).

niay

H ar pctctes e ry throce ph a lus

This brightly coloured species is a bird of moist hill evergreen. It has been seen twice near the Lam Ta Krong, and once on a tributary. Once between Heo Suwat and Pha Kluay-mai Waterfalls on 2.3.63 and on 16.3.63 much further upstream near Wang Champi, but up the sid e of the valley; finally a female on 10.8.63 near the camp. Smith took it on Khao Laem on 27.12.30.

Kingfisher. (D. 196, S. XVII) .

A fcedo aJ;this

Seen along the Lam Tha Krong a number of times, and during March 1963 probably at least two individuals were present.

White-Breasted Kingfisher. (D. 202, S. XVII).

Halcyon smymensis

Seen by P.F.C. in February 1963 and on March 3rd by the author about half-way up the hill road on to the massif.

Blue-Tailed Bee-Eater. Merops superciLiosus (D. 205, S. XVII). A flock of about 15 were found near Wang Champi in a large tree in a lalang clearing by the river on 8.2.63 . Height about 800-850 m. Bay-Headed Bee-Eater. (D. 208, S. XVII).

Merops les chenaulti

Seen regularly over the clearings at Khao Yai during March and April 1963.

Blue-Bearded Bee-Eater. Nyctiomis a.thertoni (D. 209). 1 seen 10.8.63 is the only record from within the park.

Black-Billed Roller.

DICKINSO N

Coracias benghalensLs

(D. 210, S. XVI). This bird occurs up to the edge of the hills and indeed a pair was seen apparently using a nest hole just within the park along Thanarat Road on 4.5.63.

Red-Billed Roller. (D. 211, S. XVI).

Eurystonws or ienta/is

Seen from March through to August. This bird can often be seen flying over the park- somewhat erratically. It flies slower than the similar wing-patterned Grackles: apparently all dark except for white panels in the underwing. Smith took a female at Tha Chang 19.3.27.

Great Hornbill.

Dichoceros bicomis

(D. 214, S. Frontispiece). Apparently quite common. Usually heard first and then set>n singly or in pairs. Recorded in March, April, Jul y, August and September-and probably resident on the plateau.

Little Pied Hornbill.

Anthracoceros coronaws

(D. 216, S. XVII).

This hornbill is gregarious and perhaps a wanderer in altitude. Two flocks have been seen in March along valleys in the hill evergreen on the massif, and a single bird was seen 5.5.63 at the foot of the hill on Thanarat Road-just outside the park

Waved Hornbill.

Ace rus nnclnlatus

(D.218). Views of large hornbills with all black bodies and white tails are not rare-but until 5.5.63 none was seen close enough to confirm it as this, and not the less likely, but very similar, A. plicutu~ (mentioned by Deig11a11 as Rhyticeros suhrujicollis) which is said to occur in S.W. Thailand north of the Peninsular. All birds seen have been on the plateau or on Khao Khieow.

Green-Eared Barbet.

Cyano ps f aiostr icta.

(D. 224). This bird has been seen twice - on 15.4.63 near Viravudhya Waterfa ll, and on 12.8.63 near the "Viewpoint" . It is however a green bird in a green forest and is probably more common than these two records indi cate.

A PRELl MINAH Y LI ST OF TH 8 BlH DS OF KH AO YA l NA TIO NAL PA RK

Blue-Throated Barbet.

193

Cyanops asiatica

(D. 226, S. XV). This seems to be the commonest barbet in the area-which calls all the time-but the call of C. in.cog nita (see below) is probabl y indistinguishable.

Blue-Eared Barbet.

Cyan.ops australis

( D. 227 ). One seen 11.8.63. This small barbet is hard to see and is proba bl y onl y sparsely distributed in the park.

Home's Blue-Throated Barbet.

Cy anop s incognita

( S. page 313, Riley p. 206 ). This barbet has been seen twice at close quarters by the author and once by P.F.C . . Smith took 2 females on Khao L aem on 27 and 29.1 2.30. ( Ri/ey says "Kao Lem, Chantabun" but the dates must make it the mountain within Khao Yai National Park).

Crimson-Breasted Barbet.

X antholaema haernacephala

( D. 228, S. X V). The coppersmith barbet is a lowland bird and has onl y been seen along Thanarat Road close to the park boundary. 2 males taken by Smith at Knong Phra 16.4.29., and 1 male at Tha Chang 14.3.27.

Scaly-Bellied Woodpecker.

Picus vittatus (D. 230). One seen 12.4.63 in the evergreen jungle near the camp area, another near Gaeng Geow 10.8.63. A pair was taken at Tha Chang by Smith on 20.3.27. T his species is not easy to tell from P. w nus, which Smith took at Knong Phra on 15.4.29 and the student is advised to take full notes-black on the crown/nape alone is not distinctive, but red alone or red plus black will ser ve to distinguish the adult males.

Lesser Yellow-Naped Woodpecker.

Picus chlorulophus

( D. 234 ).

Seen in March, May, July, and August. the massif and the slopes of Khao Khieow.

Probably a resident on

E.C.

DIC K INS ON

3 Toed Golden-Backed Woodpecker.

Dinopiwn juuan en se

(D. 248 ). This is probably the commo~er of the two very similar Golden backed Woodpeckers. Has been seen several times-though not always certainly separated from the following species. Taken by $mith at Tha Chang 1 male 16.3.27 and at Knong Phra1 male 2 females 10- 12.4.29.

4: Toed Golden-Baclwd Woodpecker.

Chrysucolupt cs laciJns

( D.249 ). Only seen certainly on 10.8.63 - a pair ncar the road bridge over the Lam Ta Krong. A female was taken by Smith on Khao Laem 29.12.30.

Long-Tailed Broad bill. (D. 255, S. XIII).

Psarisomus dallwusiae

This species has only been seen in the immediate vicinity of the Lam Ta Krong, several 2.3.63 and 1 only on 12.4.63. Previous autho rs' comments on distribution do not mention this area but P. cl . cycmiccwda. of S.E. Thailand (Riley p. 253) seems to be the nearest race, which suggests that Indo-Chinese forms may influence the birds of this a rea.

:Silver-Breasted Broadbill.

Se rilophu.s lww.tus

(D. 257 ). P.F.C. has recorded a small mixed flock of this, the above, and the

next species along the Lam Ta Krong in April 1962. on K hao Laem on 28.12.30.

Banded Broadbill.

Smith took a pair

Eurylninws j auanicus

(D. 259 ). The only record that I can trace is that of P.F.C. must be expected to be rare, as it is in Thailand generally.

House Swallow.

This species

Hi run do rusticct

(D. 267, S. XII ). During the 'winter' months seen regular! y flying over the lalang clearings and $Ome seen even in July 1963,

Pericrocotus speciosus

This colourful bird is a readily visible resident - keeping mainly to the canopy of the evergreen. Smith took an immature male on Khao Laem 25.12.30. H cntipus pica tu.~

Bar- Winged Flycatcher Shrike. (D. 281, S. VII) .

This species too appears to be a fairly common resident - but is invariably silent and often well above ground level and so not easily found. Smith took a pair at Tha Chang 16.3.27.

Grey Caterpillar Shrike. (D. 284) .

Cumpephu.ga .firnbriot•L

This too is a typical evergreen forest species - rather less addicted to m ixed flocks than the previous species. It is common along the trail sides at Khao Yai- climbing rapidly about trees and lianas.

Pale Ashy Drongo. (D. 287, S. VIII).

Dicrurus leucnpha cns

A dark from of this species - quite different from the one to be found in Dangkok at the same time- evidently occurs in winter months. Plentiful in February 1963. Hron~ed

Drongo. (D. 293, S. VIII) .

Clwptiu, aenea

Apparently a common resident. un the plateau.

Found along the roads and trails

Greater Racquet-Tailed Drongo. (D. 295, S. VIII).

Disse nwrus pu.radisens

This handsome bird appears to be resident and may be found from the level of the plains at Thanarat Road up to the plateau. Often in pairs or flocks.

Black-Naped Oriole. (D. 296, S. X).

Oriolus chinellsis

This species has been met with only once on 17.3.63 when 2 birds were found near the camp area. It is probably either a cool season visitor or a passage migrant. Smitlt took a male at Tha Chang 19.3.27.

196

Jungle Crow. (D. 300, S. I) . Resident

E.C . DICKI NSO N

Corvus macrorhynchos

Green-Breasted Hunting Crow. Kitta chinensis (D. 303, S. I). Fairly common in the evergreen jungle from the level of Heo Suwat Waterfall to the top of Khao Khieow. Fairy Bluebird. Irena pu ella (D. 320, S. X). This picturesque species is one of the commonest jungle birds. It can be constantly heard calling and is usually easily seen- though not always so that the light falls on it. Seen from about 700-900 m. which is most of the plateau area. Smith took a pair on Khao Laem 27.12.30. Golden-Hooded Leafbird. Chloropsis cochinchinensis (D. 325, S. III). Seen quite often on the main plateau, this would appear to be common in the park. Black-Headed Yellow Bulbul. Pycnonotus dispar (D. 329, S. IV). This bird is common in the hill evergreen but the birds have red throats- typical of what has been called P. johnsoni but is more probably a race of P. dispar . Smith took females at Knong Phra 25.2.24. and 16.4.29 and an unsexed bird at Tha Chang 14.3.29. Red-Whiskered Bulbul. Pycnonotus jocosus (D. 330, S. IV). This bird was not, I think, present in the lalang clearings when the camp was established, but it is now an evident resident. The red on the cheeks is not easily seen from any distance, but the bird cannot be confused with anything else. Stl·eaked-Throated Bulbul. Pycnonotus Juday soni (D.334) . This bird has only once been seen within the park -at Wang Cham pi on 13.4.63. But it has also been seen along Thanarat Road just outside the park.

White-Throated Bulbul.

Criniger tephrogenys

(D.337). This bird is common in the evergreen but should not be confused with the duller similar Microscelis chorlottae. The present species has a very white throat and is otherwise a contrasting brown. Taken 26.12.30 on Khao Laem by Smith.

Viridescent Bulbul.

Mi cros ce li s cha rlotta e (D. 339). Apparently somewhat less common than the preceding species but of similar appearance and much the same habitat.

Brown-Eared Bulbul.

Microscelis .fla.vala

(D. 342). First seen on the summit of Khao Khieow 9.2.63 subsequently around the camp area during March and April - this is probably quite a common bird. The greenish yellow on the wing is quite a good field character. A male was taken by Smith on Khao Laem 26.12.30.

Black-Throated Laughing Thrush. (D. 356, S. II).

Garrulox chinen.
1 seen on the slopes of Khao Khieow on 11.8.63. Taken by Smith on Khao Laem 27.12.30.

White-Crested Laughing Thrush. (D. 357, S. II ). This is the commonest of its genus in the park- and can be hea rd calling by every visitor. It is however usually hard to see. A resident.

Indian Herpornis . (D. 372).

Er pornis zantholeuca

This seems to be a common resident of the lower hill evergreen. Smith took a male at Tha Chang 22.3.27.

Spotted Babbler. (D. 378, S. III).

f>ellorneum ru.Jiceps

A small flock seen 10.8.63., this bird is a shy, rarely seen, resident. Taken by Smith- 1 female at Knong Phra 10.4.29 and 1 immature female atTha Chang 21.3.27.

This small undergrowth rambler has been seen quite often and car\ be presumed common .

Ahuott's Babbler. ( S. page 24 ).

Nlct.la cocincla aiJbo f.li

Two were seen in underbrush near the ca mp area 12. 4.63. Riley give.s "2 m ales, Kao Lem, Chantabun, June 7, 1926 a nd D ecember 28, 1930 ". On the former date Smith may well have been on K ao L em Sing, but the second bird must have been on Khao Laem within the park.

Smith also took 2 males 1 fe male at Knong Phra 9 - 10.4.29 and 2.1. :\l

Yellow-Billed Scimitar Babbler. ( D. 393, S. Ill).

Pomatorhinus schisti.ceps

This species has been seen several times and heard many more- it is fa irly common in the lo wer evergreen where there is some underbrush.

Slaty -Backed Forktail. (D. 401 ).

Enicuru s schi:J taCPus

This bird was found in December 1962 by P.F.C. and vvas seen frequently from then until 15.4.63 on which date the author found a young bird near Viravudhya Waterfall. Since then seen once on 12. 8.63. Over the area covered about 5 pairs must have been in residence: they seemed territory conscious. This is believed to be the first record of breeding from this pa rt of Thailand.

Blne Whistling Thrush. ( D . 404, S.V) .

Myophonu s r:ae ruleus

Seen once below Heo Suwat Waterfall by P.F.C. and twice abov e it by the author on 10.2.63 and 12.4.63.

Kitta cincla malabarica

(D. 421 , S. V).

This beautiful bird has been seen several times from the foot of the hill nea r 'Thanarat Roa d up to the a rea around the camp. It is fairly

common, but shy. Smith took an immature male at Knong Pbra 12.4.29. and a fema\ at Tha Chang 18.3.27.

White -Throated Rock Thrush.

M onticola gu la.ris

(D.423). An adult male was watched for some minutes by P.F.C. and the author on 9.2.63 along the road to Khao Khieow. Full field notes were taken even the white triangle on the lower throat being noted. This would appear to be about the 12th record for Thailand.

Chestnut-Bellied Rock Thrush.

Monticula rujiventris

(D.424) . One was seen,- presumabl y on passage- almost at the top of th e bill road up to Khao Yai on 3.3.63.

Blue Rock Thrush.

Monticola solitarius

(D. 424, S. V). This species may be present throughout the year but so far it has on! y been recorded from 15.9. - 14.4. It is often to be seen during th~t period in the immediate vicinity of the bungalows.

White-Browed Thrush.

Turdu s obscu ras

(D. 427).

One presumably on passage, in the edge of the eve rgreen, 10.2.63.

Grey-Breasted Flycatcher.

M uscicapa la tirostris

(D.439). This is apparently another cold season visitor, or passage migrant. It has been recorded only on 15 -16.9.62., but no doubt in view of its presence elsewhere occurs to a much greater extent.

Red-Breasted Flycatcher. (D. 440 ).

Siphia p arva

This like the preceding species can be expected throughout the cool weather in open jungle, but so far has been recorded only once: on 3.3.63 on a lone tree in a huge lalang clea ring.

[ Cyornis sp. ]

Cyornis sp

(D. 447-452, S. VI) . A male- almost certainly C. bany umas - on 16.3.63 along the Lam Ta Krong by W ang Champi, and a female on the east slope of Khao

DICKI~SON

Khieow at about 1250 m. and suspected of being C. hainana, are the only individuals of this difficult group seen. The identifications which are tentative are thanks to the skins in the collection of Dr. Boo11soug Lelwgul. Smith took C /win ana- a female- at Tha Chang on 23.11.25., C. tickellia e- 2 males- atKnongPhra 15-16.4.29, and C. whitei = C. banyumas5 males 2 females -on Khao Laem 26-28.12.30.

H)'pothymis azurea

Only seen 10.2.63, 12.4.63 and 10.8.63 in the same habitat as the preceding species. Smith took a fema le at Knong Phra 11.4.29. Probably a regular winter visitor.

[Warblers sp ?]

Ph)'Lloscopus sp! During the cool weather these small birds are probably present in good numbers- in February and March 1963 a few were seen, but never near enough or for long enough to get a useful description.

Blacl\-Throated Tailorbird.

OrthotorntLS atrogula ris (D. 489). One 13.4.63 near Wang Champi.

Rufescent Prinia. (D. 492 ).

Prinia mfescen:;

This speeies is typical of the lalang clearings but is probably not resident there. Those seen there were seen durins March-August 1963. Smitlt took a female at Tha Chang 2.3.27.

Summary: 1. A general picture is given of the bird habitats within Khao Yai National Park, Thailand.

2. A preliminary list of species recorded within the park based upon field observations over the last eighteen months and the collections of Dr. H. M. Smith [as per Riley ( 1938) J made between 30 and 40 years ago is given. 3. The list contains cross-references to good descriptions and colour plates of many of the birds mentioned. It is annotated with remarks on the probable status of some species and with field identification characters in certain cases. 4. It is hoped that this list will encourage the publication of additional data on the birds of Khao Yai National Park
