generally below 1000 m. Some records could conceivably refer to the extremely similar P. borealoides Sakhalin Leaf Warbler. The latter’s winter distribution and field characters are not well known (see Inskipp et al. 1996; C. R. Robson verbally 1998). Phylloscopus coronatus Eastern Crowned Warbler. Passage migrant, overwintering at least sporadically in the south; north B2 , centre B9 , south (historically B19 ). Forests and other areas with mature trees. Records prior to 1996 were reviewed by Duckworth et al. (1998a). Phylloscopus reguloides Blyth’s Leaf Warbler. Winter visitor, locally resident in south B3 ; north, centre, south B2 . Evergreen forest and adjacent tall regrowth, commonest in hills and mountains but occurs down to Mekong plains. Phylloscopus davisoni White-tailed Leaf Warbler. Resident; north B4 , centre B10 , south B2 . Evergreen forest and tall secondary growth above 900 m, perhaps lower in winter. • Phylloscopus cantator Yellow-vented Warbler. Conservation Significance: Globally Near-Threatened. Not At Risk in Lao PDR. Documented Range and Habitat: Winter visitor, perhaps local breeder; north, centre B10 . Evergreen and mixed deciduous forests, often beside rivers; usually at 500- 1000 m. Status Information: Records prior to 1997 were reviewed by Thewlis et al. (1998). The species is relatively widespread, usually at low density, in northern and hilly central Lao PDR. Records come from seven recent survey areas (Table 11). Post-1996 records include several in song in Phou Louey NBCA, which were still present on 13 May 1998 in suitable breeding habitat (Davidson 1998). Similar behaviour was observed in similar habitats in Nam Ha NBCA in March 1997 (Tizard et al. 1997). Phylloscopus ricketti Sulphur-breasted Warbler. Winter visitor to south, passage migrant throughout; north B2 , centre B7 , south B2 . Evergreen forests and regrowth, up to at least 1520 m on passage. Until the taxonomic status of the ‘Limestone Leaf Warbler’ is resolved, records of this species in parts of central Lao PDR may be best left unidentified; but birds in late March in Nakai-Nam Theun NBCA were clearly longdistance migrants (PD). [Phylloscopus sp. ‘Limestone Leaf Warbler’]. Breeding resident; north, centre B9 . Evergreen forest on limestone karst, dispersing to adjacent wooded non-calcareous formations outside the breeding season. This form of Phylloscopus resembles P. ricketti in external appearance but vocalisations suggest it belongs to an un-named taxon, possibly distinct at the species level (P. Alström in litt. 1997). Seicercus burkii Golden-spectacled Warbler. Winter visitor, probably breeding in south B3 ; north, centre, south B2 . Birds Evergreen forest, bamboo, streamside thickets, up to at least 1650 m. Birds breeding in the Phou Ahyon area were presumed to be S. burkii rather than S. affinis on the basis of their yellow eye-rings. They differed clearly in vocalisations and plumage from the common wintering form across Lao PDR (RJTim). The taxonomic status of ‘S. burkii’ has recently been re-assessed (Alström and Olsson in press), and it is likely that three forms recognisable as full species occur in Lao PDR. [Seicercus affinis White-spectacled Warbler]. Seasonal status unclear; north (provisionally B6 ). Habitat in Lao PDR unclear. Some recent birds in Lao PDR were left unidentified beyond S. affinis / S. poliogenys pending further experience (e.g. WCS 1995a, Tizard 1996). Birds in Nam Ha NBCA were given in Tizard et al. (1997) as S. affinis, but until the details of the various forms currently included within S. burkii are clarified, these Nam Ha birds should be considered as provisional S. affinis (RJTiz). The only historical records are from Xiangkhouang Province (David-Beaulieu 1944). Here the species was noted as a winter visitor, mainly to the low valleys (perhaps about 500 m). Elsewhere in its range it is montane and so these records are also best considered provisional until any extant specimens can be re-examined. Seicercus poliogenys Grey-cheeked Warbler. Resident; north B13 , centre B10 , south B2 . Evergreen forest and secondary growth, generally above 900 m, perhaps lower in the winter. Seicercus castaniceps Chestnut-crowned Warbler. Resident; north B4 , centre B10 , south B2 . Evergreen forest above 1000 m. Abroscopus albogularis Rufous-faced Warbler. Resident; north, centre B10 . Evergreen forest, bamboo and secondary growth above 600 m. Records prior to 1997 were reviewed by Thewlis et al. (1998). The species is common or abundant in higher hill and montane areas in and around the Nam Theun catchment, and not uncommon, or at least present, in several other survey areas. It is unlikely to be under elevated threat. Thus it was dropped from the recommended list of key species. In 1997 and 1998 it was recorded from several further areas. Abroscopus superciliaris Yellow-bellied Warbler. Resident; north, centre, south B2 . Bamboo and secondary growth within and near evergreen forest, up to at least 1450 m. Megalurus palustris Striated Grassbird (= Striated Warbler, ^K, ^T). Resident; north B2 . Reed beds, marshes, extensive tall grassland; all known localities are near water and on flat terrain, up to 1200 m. Garrulax leucolophus White-crested Laughingthrush. Resident; north B1 , centre, south B2 . Evergreen and mixed 147
Wildlife of Lao PDR: 1999 Status Report deciduous forest and tall secondary growth, riverine areas within dry dipterocarp forest, up to at least 1200 m. Garrulax monileger Lesser Necklaced Laughingthrush. Resident; north B7 , centre, south B2 . Forest, tall secondary growth and bamboo, especially mixed deciduous forest and riverine forest through dry dipterocarp forest; up to at least 1000 m. Garrulax pectoralis Greater Necklaced Laughingthrush. Resident; north, centre B10 . Evergreen and mixed deciduous forests and tall secondary growth, from foothills up to at least 1800 m. Garrulax strepitans White-necked Laughingthrush. Resident; north B6 . Evergreen forest at 600-1100 m (probably higher); uses mixed oak - pine forest in north-west Thailand. • Garrulax milleti Black-hooded Laughingthrush. Conservation Significance: Globally Threatened - Vulnerable; Potentially At Risk in Lao PDR; endemic to south Lao PDR and central and southern Vietnam. Documented Range and Habitat: Resident: south B14 . Evergreen forest at 980-1550 m. Status Information: The species was first found in Lao PDR in 1996, in the Phou Ahyon area (Thewlis et al. 1998). Since then it has been found in only one other area, Dong Ampham NBCA (Davidson et al. 1997). • Garrulax maesi Grey Laughingthrush. Conservation Significance: Globally Near-Threatened; endemic to Lao PDR, Vietnam and southern China. Not At Risk in Lao PDR. Documented Range and Habitat: Resident; north, centre B10 . Evergreen forest at 600-1700 m. Status Information: Records prior to 1997 were reviewed by Thewlis et al. (1998). The species is common in six recent survey areas in the north and central Annamites south to Nakai-Nam Theun NBCA, and in northeastern Lao PDR (Table 11). The race concerned (varennei; Plate 12), together with castanotis may best be grouped as a full species, G. castanotis Rufous-cheeked Laughingthrush (Inskipp et al. 1996; C. R. Robson verbally 1998). This proposed species is endemic to Hainan (south China), north and central Lao PDR and north and central Vietnam. Garrulax chinensis Black-throated Laughingthrush. Resident; north, centre B10 , south B9 . Evergreen and mixed deciduous forest, dense rank growth, streamside thickets within dry dipterocarp forest, bamboo; up to at least 1350 m. Garrulax vassali White-cheeked Laughingthrush. Resident; south B2 . Evergreen forest, forest edge and adjacent dense tall scrub and grass at 800-1200 m. Records prior to 1997 were reviewed by Thewlis et al. (1998). As the species is widespread on the Bolaven Plateau and recorded in the Phou Ahyon area, and tolerant of habitat degradation, it was 148 dropped from the recommended list of key species. Large flocks have subsequently been recorded on the Dakchung Plateau and in Dong Ampham NBCA (Davidson et al. 1997, Showler et al. 1998a). Although sometimes stated to inhabit central Lao PDR (e.g. King et al. 1975), this appears to be based on David-Beaulieu’s (1949-1950) records from Muang Somoy, which was one of his few observation sites falling within south Lao PDR. Special Significance: Endemic to south Lao PDR, east Cambodia and central and south Vietnam. • Garrulax gularis Rufous-vented Laughingthrush (included in G. delesserti Rufous-vented Laughingthrush by ^K). Conservation Significance: Little Known in Lao PDR. Documented Range and Habitat: Resident; north B8 , centre (historically, Delacour and Jabouille 1940). Secondary growth, scrub, bamboo and evergreen forest in hills and mountains. Status Information: The only recent record is from Nam Et NBCA where a presumed pair was seen in secondary scrub with much bamboo at 1000 m in May 1998 (Davidson 1998; DAS). The few documented historical records all came from Xiangkhouang Province: a small series was collected in the mountains (Delacour and Jabouille 1927) and, while David- Beaulieu (1944) never saw the bird in the field, he once found a villager carrying one. Nape is given as a locality by Delacour and Jabouille (1940), although we have traced no primary reference to the species there. The lack of recent records indicates that the species should be considered Little Known in Lao PDR. G. delesserti Wynaad Laughingthrush, within which this species is sometimes included (e.g. King et al. 1975), was considered to be Globally Near-Threatened by Collar et al. (1994), but this designation does not include gularis. • Garrulax sp. A. Laughingthrush sp. A. Conservation Significance: Little Known in Lao PDR; perhaps endemic to south-east Lao PDR and probably adjacent Vietnam. Documented Range and Habitat: Resident; south B3 . Forest undergrowth, including at the edge of degraded areas, at 1350- 1450 m. Status Information: A laughingthrush seen several times in the Phou Ahyon area in May 1996 fitted no described form. Although birds showed some similarities to G. rufogularis Rufous-chinned Laughingthrush (recorded from Indochina only in west Tonkin, Vietnam; C. R. Robson in litt. 1998), the number of plumage differences indicates the form should be left unidentified pending further taxonomic investigation. It is likely to have a restricted range and may be at risk, so is classed as Little Known in Lao PDR. • Garrulax merulinus Spot-breasted Laughingthrush. Conservation Significance: Globally Near-Threatened; Little Known in Lao PDR. Documented Range and Habitat: Resident; north B13 . Dense thickets within evergreen forest, including bamboo tangles, forest edge and secondary growth from
