Laos is an important country for bird conservation. Bird surveys between 1992 and 1996, the first since 1949, covered 20 main areas, with incidental records from many others.

This paper reviews the status of all Lao species reported to be of elevated conservation concern (key species) in any of the following categories: Globally Threatened or Globally Near-Threatened (sensu Collar and Andrew 1988 and Collar et al. 1994), and At Risk or Rare in Thailand (sensu Round 1988 and Treesucon and Round 1990). Several additional species are covered which have clearly undergone a National Historical Decline in Laos. A comprehensive review of other Lao species was not possible, and some species which are in truth of conservation concern have doubtless been overlooked. Historical and modern records were reviewed and population trends identified where possible.

Current global status listings (Collar et al. 1994) were supported, except that consideration should be given to changing Red-collared Woodpecker Picus rabieri and Sooty Babbler Stachyris herberti from Threatened to Near-Threatened. If the Lao situation is representative of the species throughout their range, then consideration should also be given to placing Ratchet-tailed Treepie Temnurus temnurus and River Lapwing Vanellus duvaucelii as Near-Threatened.

Twenty-seven Globally Threatened species are known from Laos, of which there are recent records of 22. There are recent unconfirmed records of two more. Forty-seven Globally Near-Threatened species are known from Laos, of which there are recent records of 39; there are unconfirmed records of one further species. Five Globally Threatened and five Near-Threatened species were recorded for the first time in Laos in recent years, suggesting that further species of elevated conservation concern remain to be found.
