Wildlife of Lao PDR: 1999 Status Report - IUCN

Wildlife of Lao PDR: 1999 Status Report
Dicrurus paradiseus Greater Racket-tailed Drongo. Resident;
north, centre, south B2 . Evergreen and mixed deciduous
forests and tall secondary growth, generally below 1000 m.
Hypothymis azurea Black-naped Monarch. Resident; north,
centre, south B2 . Evergreen and mixed deciduous forest and
other thick vegetation types; up to at least 1200 m, although
generally lower.
Terpsiphone paradisi Asian Paradise-flycatcher. Seasonal
status unclear; north, centre, south B2 . Evergreen forest, tall
secondary growth, mainly lowlands but up to at least 1450
m.
• Terpsiphone atrocaudata Japanese Paradise-flycatcher.
Conservation Significance: Globally Near-Threatened; Little
Known in Lao PDR. Documented Range and Habitat:
Passage migrant; centre B10 , south (historically B19 ). Evergreen
forests. Status Information: Recorded only on the Bolaven
Plateau in 1930 (Engelbach 1932) and in Nakai-Nam Theun
NBCA in 1994 (Thewlis et al. 1998), both in April.
Aegithina tiphia Common Iora. Resident; north, centre,
south B2 . Open forest and forest edge, gardens, secondary
growth and wooded areas; among natural habitats, dry
dipterocarp forest supports the highest densities. Occurs to
at least 1050 m.
Aegithina lafresnayei Great Iora. Resident; north, centre,
south B2 . Evergreen forest and adjacent secondary growth,
generally below 750 m.
Tephrodornis gularis (= T. virgatus, ^K, ^T) Large
Woodshrike. Resident; north B1 , centre, south B2 . Forests and
well wooded country up to 1500 m.
Tephrodornis pondicerianus Common Woodshrike. Resident;
centre B10 , south B2 . Mixed deciduous and dry dipterocarp
forest, sometimes in other open areas with scattered trees;
generally below 700 m. The record for Nam Et / Phou Louey
NBCAs in Davidson (1998) was an editorial error.
Conservation Management and Research Proposed for
Corvidae:
• Conservation of adequate habitat.
• Hunting controls on larger species (magpies and jays),
notably White-winged Magpie and Indochinese Green
Magpie; both are restricted in range and the former is
particularly conspicuous to hunters.
• Field investigation of reasons why Large-billed Crow and
perhaps Black-billed Magpie have declined; nest disturbance
may be a major factor.
• Field investigation of the use of the various types of dry
dipterocarp forest by White-browed Fantail.

Cinclidae: Dippers (1 species)
• Cinclus pallasii Brown Dipper. Conservation Significance:
Potentially At Risk in Lao PDR. Documented Range and
Habitat: Resident; north, centre B10 . Upland streams and rivers
in both forested and cleared areas; generally above 600
m. Status Information: Records prior to 1997 were reviewed
by Thewlis et al. (1998). Historical and recent records both
come from scattered montane areas of the north and down
the Annamites into central Lao PDR. The species is known
from six recent survey areas (Table 11). It was only considered
to be common, and only locally so, in two. It has not
been found in various other areas of superficially suitable
habitat within its Lao range. There may be specific
microhabitat requirements. In the absence of any understanding
of these, and given the ecological fragility of upland river
systems in Lao PDR, the species is retained as Potentially At
Risk in Lao PDR.
Conservation Management and Research Proposed for
Dippers:
• Conservation of adequate habitat.
• Research into factors leading to the patchy distribution
of the species.
Muscicapidae: Thrushes, shortwings, true flycatchers,
robins, redstarts, forktails, cochoas, chats (70 species)
Monticola gularis White-throated Rock Thrush. Winter
visitor; north B9 , centre B16 , south B2 . Forests, mainly evergreen;
generally below 700 m.
Monticola rufiventris Chestnut-bellied Rock Thrush. Resident;
north B13 . Open evergreen forests and cleared areas above
1500 m.
Monticola solitarius Blue Rock Thrush. Winter visitor;
north, centre, south B2 . Open forest with rocky areas, limestone
karst, open stream and river banks, secondary growth
with bare areas, towns and villages; up to at least 1500 m.
Myophonus caeruleus (= Myiophoneus caeruleus, ^T; =
Myiophonus caeruleus, ^Sm) Blue Whistling Thrush. Winter
visitor and local resident; north B1 , centre, south B2 . Forested
streams (especially in rocky areas) and dry karst valleys, from
lowlands to highest altitudes.
Zoothera citrina Orange-headed Thrush. Seasonal status
unclear; north B9 , centre B10 , south B2 . Evergreen forest, particularly
in gullies, and mature secondary growth, including on
limestone, to at least 1165 m.
