Grey Laughingthrush. Nakai-Nam Theun NBCA, December 1998. The chestnut head-markings are characteristic of race Garrulax maesi castanotis of this Globally Near-Threatened species, which has a very small world range. W. G. Robichaud / WCS and IUCN. Silver-eared Mesia, Nakai-Nam Theun NBCA, spring 1997. This red-throated race Leiothrix argentauris ricketti is restricted to evergreen forest of central and northern Indochina and to adjacent southern China. J. A. Tobias / WCS and IUCN. Coral-billed Scimitar Babbler, Nakai-Nam Theun NBCA, April 1994. A species typical of hill and montane evergreen forest in Lao PDR. T. D. Evans / WCS. White-winged Magpie. Nakai-Nam Theun NBCA, December 1998. This Globally Near- Threatened species has a small world range, occurring only in parts of Indochina and southern China. W. G. Robichaud / WCS and IUCN. Birds 141
Wildlife of Lao PDR: 1999 Status Report Status Information: Records prior to 1997 were reviewed by Thewlis et al. (1998). It is unclear whether there has been a major decline. Observations come from ten recent survey areas (Table 11) and other incidental sites. These come nowhere near matching one past count, of thousands along the Xe Banghiang (David-Beaulieu 1949-1950). There is probably a complex pattern of seasonal occurrence at individual sites. The record in Showler et al. (1998b) was on the Xe Kong west of Phou Ahyon and the Dakchung Plateau and 20 km south of Xe Sap NBCA. Hirundo daurica Red-rumped Swallow. Winter visitor; north B2 , centre B9 , south B2 . Largely in open country, especially near wide rivers. Records from prior to 1994 were reviewed by Thewlis et al. (1996). Hirundo striolata Striated Swallow (included in H. daurica Red-rumped Swallow by ^K, ^T). Resident; north, centre, south B2 . Rugged country with exposed cliffs in both limestone and non-calcareous regions. Records from prior to 1994 were reviewed by Thewlis et al. (1996). Delichon urbica Northern House Martin (= Common House Martin, ^K, ^T). Winter visitor; north (historically B21 ), centre B9 , south (historically B19 ). The few recent records were of small numbers in flocks of mixed hirundines over pools and agricultural land on the Nakai Plateau. Records prior to 1996 were reviewed by Duckworth et al. (1998a). The absence of historical records of Asian House Martin, which recent records show to be much commoner than Northern, suggests that re-examination of any historical house martin specimens (which were all identified as Northern) that can be traced would be desirable. Delichon dasypus Asian House Martin. Winter visitor; north B1 , centre B10 , south B5 . Forests, open wooded country, around villages, especially in hilly and mountainous areas, but locally over the Mekong plain. First recorded for Lao PDR in 1994 (Evans and Timmins 1998). Field characters of birds in Lao PDR were discussed by Duckworth et al. (1998a). Delichon nipalensis Nepal House Martin. Presumed resident; north B9 , south B2 . Escarpments and limestone karst, feeding over adjacent flatlands. First recorded in 1993 (Thewlis et al. 1996). Records prior to 1996 were reviewed by Duckworth et al. (1998a). Subsequently the species has been seen around limestone karst near Vangviang, a substantial northward extension of its known distribution in Lao PDR (RJTim). Conservation Management and Research Proposed for Swallows and martins: • Habitat conservation, with special attention to Plain Martin and Wire-tailed Swallow. 142 • Field investigation of causes behind the undoubted decline in Plain Martin; egg collecting from colonies could perhaps be a contributory cause, although there is no direct evidence (but see Pied Kingfisher and Blue-tailed Bee-eater). • Location and monitoring of breeding colonies of Plain Martin. These are currently known only from the Mekong in Louangphabang Province and in Sangthong District. Pycnonotidae: Bulbuls (17 species) Spizixos canifrons Crested Finchbill. Resident; north B6 . Forest edge, scrub, grass and secondary growth above 1200 m. Pycnonotus striatus Striated Bulbul. Resident; north B13 , centre (WCS 1996a). Evergreen forests and secondary growth above 1200 m. Pycnonotus atriceps Black-headed Bulbul. Resident; north, centre, south B2 . Evergreen forest, secondary growth, riverine forest, generally below 800 m. Pycnonotus melanicterus Black-crested Bulbul. Resident; north, centre, south B2 . Evergreen forest and forest edge, mature secondary growth, dense scrub up to at least 1250 m. Pycnonotus jocosus Red-whiskered Bulbul. Resident; north, centre, south B2 . Cultivation, villages, towns, secondary growth, forest edge up to at least 1600 m. Often rather locally distributed in natural habitats but abundant in degraded ones. Pycnonotus sinensis Light-vented Bulbul (= Chinese Bulbul, ^T). Presumed winter migrant; north (TDE). Sole Lao record came from lowland limestone scrub. First recorded for Lao PDR in 1999 near the southern tip of Nam Kading NBCA (TDE), when one bird of race P. s. sinensis was seen. Pycnonotus xanthorrhous Brown-breasted Bulbul. Resident; north B8 . Scrub, secondary growth and rank grassland above 1020 m. Records prior to 1996 were reviewed by Duckworth et al. (1998a). Pycnonotus aurigaster Sooty-headed Bulbul. Resident; north B9 , centre B10 , south B2 . Dry dipterocarp and other open forest, its secondary derivatives, scrub and tall grass; up to at least 1560 m. Pycnonotus finlaysoni Stripe-throated Bulbul. Resident; north, centre, south B2 . Degraded forest, secondary growth, scrub, chiefly in lowlands and foothills.
