BIRDS J. W. Duckworth, P. Davidson and R. J. Timmins INTRODUCTION Species Included The following list includes all bird species recorded from Lao PDR. Provisional records (those modern ones where observers are confident of the identification but were unable to clinch it, and those historical ones where subsequent information suggests a re-examination of any extant specimens would be desirable) are placed in square brackets. There are also a few ‘potential’ records. These refer to cases where it is difficult to distinguish between a closely similar pair of species (e.g. Riparia riparia and R. diluta; Phylloscopus sichuanensis and P. chloronotus) and most or all sight records of birds in these groups are best left unidentified to species. There are many records of birds observed in Thailand at sites such as Chiang Saen (Chiang Rai Province) which include records in the Mekong channel and on islands in the river. The latter are part of Lao territory. All such records known to us are incorporated in the following list, but others doubtless remain to be traced. A few species which have been stated to occur in Lao PDR in largely authoritative sources, but for which adequate supporting evidence cannot currently be traced, are listed in the Appendix to this chapter. Recent field work has added many new species to the country’s list and others will undoubtedly be found as work continues; Table 9 lists some potential further additions. Approximately 700 species of bird are known or provisionally recorded from Lao PDR and another 100 or so are reasonably likely to occur. Although birds are by far the best surveyed class of animals in Lao PDR, a more precise total would be of limited use. The pace at which species new to the country are being found would render any ‘accurate’ figure obsolete within months of publication. Taxonomy and Nomenclature Sequence, species limits and scientific and English nomenclature follow An annotated checklist to the birds of the Oriental region (Inskipp et al. 1996). Differences in species limits and nomenclature from the two field guides most frequently used in Lao PDR (King et al. 1975, Lekagul and Round 1991) and from The distribution and taxonomy of birds of the world (Sibley and Monroe 1990, as amended 1993) are indicated. The decisions of Inskipp et al. (1996) are retained uniformly, as the present list is not a taxonomic work. Names differing only in orthography from those in Inskipp et al. (1996) are not presented as alternatives. References for alternative treatments are abbreviated as in Inskipp et al. (1996): ^K, King et al. (1975); ^Sm, Sibley and Monroe (1990, as updated 1993); ^Sm 1 , Sibley and Monroe (1990 only); ^Sm 2 , Sibley and Monroe (1993 only); ^T, Lekagul and Round (1991). Distribution Within Lao PDR For each species, one primary source is cited for each of north, central and south Lao PDR (see main Introduction) in which it has been recorded. Where one source listed records for adjacent regions, it is only cited after the last. For example, ‘centre, south (Thewlis et al. 1998)’ implies that Thewlis et al. (1998) listed the species for both centre and south. No attempt is made to indicate the first record for the region, and indeed the focus is on recent (post-1988) information. Where possible, citation is to records in refereed journals rather than to those in internal survey reports or other grey literature. More details are given for significant records not yet formally published than for those published. Key distribution references are abbreviated as follows: (recent) B1 Duckworth (1996a), B2 Thewlis et al. (1996), B3 Timmins and Vongkhamheng (1996a), B4 Tizard (1996), B5 Davidson et al. (1997), B6 Tizard et al. (1997), B7 Tobias (1997), B8 Davidson (1998), B9 Duckworth et al. (1998a), B10 Evans and Timmins (1998), B11 Round (1998), B12 Showler et al. (1998a), B13 Showler et al. (1998b), B14 Thewlis et al. (1998), B15 Evans et al. (in prep. a), B16 Evans (in prep.), B17 Walston (in prep.), (historical) B18 Bangs and Van Tyne (1931), B19 Engelbach (1932), B20 Delacour and Greenway (1940a), B21 David-Beaulieu (1944), B22 David-Beaulieu (1949- 1950). Seasonality of Occurrence Seasonality of occurrence is based on the compilers’ and other reviewers’ experience. No comprehensive analysis of seasonality of Lao records has previously been attempted for most species. Some species are covered nationally in Thewlis et al. (1996), Duckworth (1996a) and Duckworth et al. (1998a), and locally in various sources, notably Engelbach (1932), David-Beaulieu (1944) and Cunningham (1998). Objective categorisation of the seasonal status of all species based solely on Lao records is difficult. Many species are still known by few records. Recent bird survey work has been concentrated in the months of December to May with very little during July to October. Few areas have had multiple visits spread across seasons. Therefore, seasonal categorisations have incorporated understanding of species’ seasonal status from neighbouring countries (particularly Thailand; Lekagul and Round 1991). It is possible that some assessments will turn out to be misleading. The alternative would have been the cumbersome insertion of ‘presumed’ before the seasonal status assessment of most species. This has only been used for species where although we believe the assessment given to be correct, a larger-than-usual doubt remains. The selection of species where ‘presumed’ is used is necessarily somewhat subjective. Ongoing analysis of recent and historical records will doubtless allow resolution of 69
