Global status category codes: G(N)T, Globally (Near-)Threatened; 0, considered secure. Global status Reasons: 1, species occupies areas or habitats under no obvious threat and seems unlikely to be under specific threat. 2, although undoubtedly harvested whenever opportunity permits, species is clearly widespread, still relatively numerous, and tolerant of degraded habitat 3, sole Lao record found to be in error. 4, further information gathered: see species account. 5, status is analogous to that of various large waterbirds, so species is reclassified accordingly. 6, resident species with no recent field records. Historical Sources The ongoing Annotated checklist and bibliography of the birds of Indochina (Mlikovsky and Inskipp in prep.) presents a cross-referenced species checklist of all literature (published and ‘grey’) and the many unpublished notes available to the compilers. This base is invaluable to all bird surveyors in the region. A synopsis of the historical information sources for Lao PDR is given in Thewlis et al. (1998). Recent Information Bird surveys exceeding one week have taken place in 30 areas of Lao PDR, supplemented by intermittent observations in and around the towns of Vientiane and Savannakhet (Table 11, Fig. 6). All surveys used a similar approach, except that in Nam Kan PNBCA (Pasquet 1997). Ethical, conservation and practical grounds meant that these surveys relied overwhelmingly on sight records rather than specimen collection. Where specimens would be desirable to confirm a record, records are square bracketed. Specimen collection allows objective subsequent verification of records (except in cases of fraud: see e.g. Knox 1993). This is not possible with sight records, but the problem can be minimised by observers documenting unusual records in detail and securing photographs and tape-recordings. To minimise the number of mistaken identifications in Birds this review, a conservative approach is taken to inclusion of records. Where a bird list in a report is dominated by species likely to occur and where unexpected records are discussed, and/or where observers are known to be experienced in the region and to make identifications critically (with detailed field notes and subsequent examination of specimen collections) all records are included, unless specifically retracted by the original observer(s). By contrast, species lists which present a number of unlikely records without comment suggest that the observer may not have been aware of the records’ significance, and thus was unfamiliar with the avifauna in general. The cautious course is taken of excluding the whole of such lists from this review. Many survey reports are written with insufficient time for surveyors to check skin collections or elusive references. The need for speedy output means that many of them contain a few errors, both typographical and of fact. Therefore, in cases of inconsistency, journal papers are assumed here to be more accurate than survey reports. It is particularly helpful where they detail the retractions and corrections made to survey report lists, as it is then unambiguous that a record omitted in the journal paper was not accidentally deleted (see, e.g., Thewlis et al. 1996: 64). The more significant records subsequently retracted or modified from internal reports are mentioned here. 77
