Wildlife of Lao PDR: 1999 Status Report - IUCN

Wildlife of Lao PDR: 1999 Status Report
• Gallinago nemoricola Wood Snipe. Conservation Significance:
Globally Threatened - Vulnerable; Little Known in
Lao PDR. Documented Range and Habitat: Winter visitor;
north (historically B21 ); centre B9 . Recent records from wide
forest rivers at 520 m. Status Information: Records prior to
1997 were reviewed by Thewlis et al. (1998). Historical
records come only from Xiangkhouang Province (David-
Beaulieu 1944), recent observations only from the Nakai Plateau
(four singles in 1995). Assessing this species’s status is
difficult, as it is a skulking bird, but it is sufficiently distinctive
from other snipes to suggest that it would be only rarely
overlooked. The listing in Table 7 of Srikosamatara et al.
(1992) was an editorial error for Wood Sandpiper.
Gallinago stenura Pintail Snipe. Winter visitor; north B2 ,
centre B9 , south B2 . Marshy areas, paddy-fields; occasionally
along forest rivers. The species’s similarity to Swinhoe’s
Snipe make it difficult to determine status, but previous specimen
records indicate that most or all such birds observed
recently are likely to be Pintail Snipe.
[Gallinago megala Swinhoe’s Snipe]. Non-breeding visitor,
perhaps vagrant; south (provisionally B11 ). Sole Lao record
was from a sedge-bed. First recorded, albeit provisionally,
for Lao PDR on 29 March 1997: two birds in Dong
Khanthung PNBCA (JAW in Round 1998).
Gallinago gallinago Common Snipe. Winter visitor; north,
centre, south B2 . Marshes, paddy-fields, marshy stream and
river banks.
Numenius arquata Eurasian Curlew. Non-breeding visitor;
north (historically; see below). Wetlands. There are no published
primary records, but two were seen by the Mekong
10 km west of Vientiane on 29 December 1962 by W. W.
Thomas (in litt. to C. M. Poole 1999).
Tringa erythropus Spotted Redshank. Winter visitor; north B9 ,
centre B10 , south B2 . Wide rivers, marshes, margins of pools,
adjacent cultivation. Records prior to 1994 were detailed in
Thewlis et al. (1996).
Tringa totanus Common Redshank. Winter visitor; north
(Perennou and Mundkur 1991), centre B9 . Habitat use in Lao
PDR similar to congeners. Records prior to 1996 were reviewed
in Duckworth et al. (1998a). Delacour and Jabouille
(1940) listed the species for south Lao PDR but we have
traced no individual records.
Tringa stagnatilis Marsh Sandpiper. Winter visitor; north B10 ,
centre B9 . Marshy margins of pools, sand-bars in wide slowflowing
rivers. Delacour and Jabouille (1940) implied that
the species occurred in south Lao PDR, but we have traced
no individual records.

Tringa nebularia Common Greenshank. Winter visitor;
north B2 , centre B10 , south B2 . Marshes, pools, wide slowflowing
rivers.
Tringa ochropus Green Sandpiper. Winter visitor; north B1 ,
centre, south B2 . Shady pools, slow forest rivers, occasionally
around other surface water.
Tringa glareola Wood Sandpiper. Winter visitor; north B2 ,
centre B10 , south B2 . Marshes, short flooded vegetation, including
cultivated areas; sand-bars in wide slow-flowing rivers.
Xenus cinereus (= Tringa cinerea, ^Sm) Terek Sandpiper.
Vagrant; north (historically B21 ). Sole Lao record was in rice
paddies at 1150 m near Xiangkhouang (David-Beaulieu
1944).
Actitis hypoleucos (= Tringa hypoleucos, ^Sm) Common
Sandpiper. Winter visitor; north, centre, south B2 . Edge of all
water-bodies.
Calidris alba (= Crocethia alba, ^K) Sanderling. Presumed
passage migrant; south B15 . Mekong sand-bars. First recorded
in 1996 (Evans et al. in prep. a).
Calidris ruficollis Red-necked Stint (= Rufous-necked Stint,
^K, ^Sm, ^T). Presumed passage migrant; north
(provisionally B9 ), centre B16 , south B15 . Mekong sand-bars. After
a provisional record in Vientiane on 21 November 1994
(RJTim), the first confirmed record for Lao PDR was in southern
Champasak Province in May 1996 (Evans et al. in prep. a).
Calidris temminckii Temminck’s Stint. Winter visitor;
north B2 , centre B16 ; south B15 . Margins of standing and slowflowing
water in and beside large rivers with much exposed
sediment; likely also to use marshland but no records as yet
from such habitat.
Calidris subminuta Long-toed Stint. Presumed passage
migrant; north B9 , south B15 . Mekong sand-bars. First recorded
for Lao PDR in 1995 (Duckworth et al. 1998a).
Calidris alpina Dunlin. Non-breeding visitor; north B9 ,
south B15 . The only Lao records were on Mekong sand-bars,
in 1995, 1996 and 1998 (Duckworth et al. 1998a, Evans et
al. in prep. a; J. N. Dymond per C. R. Robson in litt. 1999,
TDE).
Calidris ferruginea Curlew Sandpiper. Presumed passage
migrant; south B15 . Mekong sand-bars. First recorded for Lao
PDR in 1996 (Evans et al. in prep. a).
Philomachus pugnax Ruff. Presumed passage migrant;
south B15 . Mekong sand-bars. First recorded for Lao PDR in
1996 (Evans et al. in prep. a).
